The pros and cons of your Electric Bike Battery

by Chirag November 26, 2018
written by Chirag

Whenever you hear the word battery, the first thing that should come to your mind is electrochemical cells. I will tell you that a battery is a device that contained electrochemical cells which power electrical devices like bikes, mobile devices, electrical cars and torches.

There are two categories of batteries, which are the Primary Electrochemical cell Battery and the Secondary Electrochemical cell Battery.

The Primary Electrochemical Cell: this type of battery is a non-rechargeable battery whereby once the electrode migration is complete, there is no reversal and the next thing to do is disposing. Examples are the Alkaline batteries.

The Secondary Electrochemical Cell: this is a rechargeable type of battery that permits the reversal of ions between the electrodes and let the chemical reaction occur over and over for a specific period of time. Examples are the Lead-acid and Lithium-Ion batteries.

You can get your 48v lithium ion battery for bikes for the best experience in using rechargeable batteries for bikes.

Secondary or rechargeable batteries are supposed to be charged using electric current before its first usage, so as to make the battery work for a very long period of time.

The charge cycle of your battery is also a very important thing to consider because the number of times your battery is being recharged reduces its lifespan until it stops working. Your battery can still sustain several hundreds of recharging but still relatively depends on the type of battery it is.

The way you maintain your battery is also a key factor in the battery lifespan. for example, if your battery is always prevented from moisture and high temperature, it will last longer than when you use it in the opposite manner. Generally, if you use your electric bike battery frequently, its quality will reduce after 3 to 5 years.

 

The different types of battery and their lifespan

  • Lithium batteries: It’s the best battery for electric bikes and it can hold up to 1000 charge cycles or more depending on maintenance. Especially the latest lithium iron phosphate models.
  • Nickel batteries: it’s more likely the second best for bikes, it has around 500 charge cycle but you can probably get more if you give it the adequate maintenance.
  • Lead batteries: This is the least of them all, doesn’t work for too long but can still last up to 300 charge cycles on the first-generation electric bikes.

Even if your battery has reached its maximum number of charges, it still doesn’t become totally useless. What your battery will lack will just be the reduction in its efficiency thereby, it will start holding its charge time for a short period and the performance will also be affected.

Do you think leaving your battery unused is helping your battery lifespan? No, it’s not because the energy that is stored in the battery escapes gradually. The battery will “self-discharge” completely until it has no energy left. If the battery now remains totally uncharged for a long period of time, the probability of an irreparable damage will be very high owing to the chemical reactions that would have taken place inside the battery.

How to give your battery a longer lifespan?

  1. Charging: when charging your battery make sure you use the charger and adapter supplied with the battery, let your battery cool off before charging and always make sure your battery charges fully i.e. charged to 100% before using.
  2. Storage: Just as I said earlier, make sure your battery is always shielded from any form of moisture and high temperature (preferably between 0°C – 20°C).
  3. Cleaning: Always clean off dirt from the battery power connector to avoid rusting or corrosion.

Conclusion: having a rechargeable battery for your bike is good but, having a lithium-ion rechargeable battery precisely and strictly following the maintenance step is best for you and your bike. This will make you enjoy the full efficiency of your bike and its attribute.

Tips to Find a Best Manufacturer in China

by Chirag November 17, 2018
written by Chirag

How Do I Get Started in Finding a Manufacturer If I Don’t Know Anyone In China?

Original Design Manufacturer (OEM) companies are those that design and manufacture a specified product. The product is later branded by another firm for sale. OEM companies in China have doubled in size and number over the last couple of years. They are now capable of taking orders from many clients simultaneously.

OEM companies let the brand company get their products without necessarily running the factory. This type of trade is common with international companies which purchase manufactured goods and retail them under their brand name. In this case, the manufacturing company is the OEM.

In recent years, China has changed its manufacturing strategy by keeping the factory costs as low as possible while producing high-quality goods.

How do I find the right Manufacturer?

If you don’t know any Chinese resident, it is still possible for you to build a successful long-term relationship with a manufacturing company. Here are ways n which you can find the right manufacturer:

  1. Identify a couple of potential suppliers that you would be interested to work with. Initiate direct communication with these companies to negotiate the pricing. It can be hard finding the right manufacturing company and building a successful relationship.

Some of the ways that you can meet potential suppliers are via a sourcing agent, Alibaba.com, and through canton fair.

  1. Talk to your close friends and family. Ask them if they can connect you to any manufacturing company in China
  • Pay a visit to the factory. This will allow to clarify any misunderstandings and talk with them to let them know exactly what your expectations are. Use that opportunity to look at samples and review the facility to see whether they’re well equipped.
  1. Use prototyping methods to come up with the final design
  2. Conduct enough research about the company before entering into any form of agreement with them

The Pros and Cons of Outsourcing Manufacturers in China

Cons

1. Finding the right factory

The biggest challenge that people face is finding the right company to work with.

2. Language Barrier

Communication is another issue that makes it difficult for international companies to outsource in China. Language barriers can lead to misunderstandings which can affect the quality of the final product.

3. Stigma

Most people have a low opinion about products that are made in China

4. Good Quality

At times, the quality of goods is the same as that you would have gotten if the products were manufactured domestically.

Pros

1. Lower costs

Generally speaking, it is cheaper to get your goods produced in China. This is after you have factored in shipping costs and duties.

This is a huge advantage for companies who are working on a tight budget.

2. Better Service

Chinese manufacturers are more likely to give you better service compared to domestic manufacturers.

3. Higher Output/Quicker Time

Most of the factories are able to produce large orders within a relatively short time. These quick turnaround times are really impressive for international companies.

When you want to work with a domestic manufacturer, you might be disappointed because they often have a limited capacity and so they can’t deliver within the expected time.

3 Useful Tips for Store Adhesive Tape

by Chirag July 24, 2018
written by Chirag

When it comes to most products like food; refrigeration prevents the food from going bad. The ‘Use by’ dates’ guarantees freshness. But, not all products come with such simple guidelines, right?

Most products like adhesive tapes can and will degrade and depreciate with time.

Tape storage is critical in its longevity. Ensure you know how and why to store it, even narrows down to how tape is manufactured. then contact your adhesive tape suppliers.

First of all, let’s take a keen look at these tapes.

The adhesive tapes are manufactured from natural rubber or certain types of pressure sensitive resin. Through simple oxidation, these materials can easily have their bonds broken. Exposure to extreme heat; natural or artificial can also have devastating effects on the adhesiveness of the tape.

The continuity of these tapes degradation over time can have a devastating impact in the tape adhesiveness.

Well, these are some other ways your adhesive tape may get degraded.

  1. Applied stress: electrical, radiation, mechanical or any other form of pressure.
  2. Environment: the liquids, solids, and gases that come into contact with the tape.
  3. Temperature: the higher the temperature, the higher the degradation.

The overall effect of each of these changes depends on how long a given condition exists. Put simply; they are all dependent on time.

While the manufacturer may add antioxidants, heat stabilizers and formulas to decelerate aging, they don’t protect the reliability of adhesive tape indefinitely. You’ll need to do something to stop the degradation.

To avoid these natural courses degrading your tape, the first step should be implementing the manufacturer’s storage guide.

The proper storage improves the quality of your adhesive tape and gives the best value for your dollar.

So, what are the best storage tips for adhesive tapes?

Well, how can you keep track of inventory at the same optimum quality as delivered to your premises? These are some tips to follow when transporting and storing adhesive tapes.

  1. Avoid direct sunlight

Do not put your adhesive tape near a window or any other place that it can soak UV rays. Exposure to UV rays for long affects the viscous nature making it hard and brittle. That would not be last long.

  1. Be mindful of temperatures

Too much heat or cold is not suitable for this tape. High heat can melt the adhesiveness making it sticky and messy. Then you have to give it up.

If you keep it in shallow temperatures, the tapes may become too hard and brittle. Ideally, store this tape in a calm and dry place.

  1. Develop a cycling system for your tape

Despite how hard you try, the tape is still going to give way at some point in time. To minimize wastage develop a cycling system.

Here, emphasize the need to use the older tapes first before releasing the new ones. Well, you can do this with the help of a simple labeling system.

Whereas the tape doesn’t get better with age, if you maintain it correctly, it will be ready for use when you need it.

written by Chirag

The manufacture of variety of smart devices currently has become an easy task for many upcoming companies. In recent years the manufacture of different devices such as smartphones, laptops, televisions, smartwatches, and smart home devices has risen. Xiaomi a Chinese electronic and software manufacturing company is one of the many companies producing a variety of devices. Started in 2011, the company has grown to become a universal company.

Xiaomi is manufactures the following products:

  • Smartphones
  • Applications
  • Smartwatches
  • Televisions

These are only but a few of the products they produce. Presently Xiaomi is the fourth best smartphone manufacturing company and the best in China. To increase its manufacturing capabilities, Xiaomi has over 15000 employees in various countries such as India, Malaysia, Singapore, and China. The company is now expanding its territories to other countries such as:

  • Philippines
  • South Africa
  • Indonesia

History of Xiaomi Smart Manufacturing

Xiaomi was founded by Lei Jun, Lin Bin, Dr. Zhou Guangping, Lui De, Li Wanqiang, Wong Kong-Kat, and Hong Feng. Xiaomi publicly launched its first android-based firmware in August of 2010. The firmware was similar to that of Apple’s iOS and Samsung’s TouchWiz. Since its introduction to the market, the company has produced very sleek devices every year.

Xiaomi Mi 1 was the first smartphone produced by the company. Later in 2012, the company produced a second version of its first smartphone “Xiaomi Mi 2.” This smartphone was a breakthrough for the company due to its vast sales. Ten million plus Xiaomi Mi 2 was sold worldwide. In 2013, the company announced production of three-dimensional television. That was not the end of the year for the company, in the same year they manufactured Xiaomi Mi 3.

The company continued to make huge strides in device manufacturing sector. September of 2013, the company stated ideas of opening its first service center in Beijing, China. In the same year, the company sold over fifteen million smartphones making it the fifth best smartphone manufacturing company on China.

Singapore was the first country to have a Xiaomi company outside China. The company was launched in 2014. Since that year, the company has made huge impact in the smart devices manufacturing opening various companies in different countries in Asia. Xiaomi has grown to become one of the best in the market.

Xiaomi Products and Features

Apart from the manufacture of smartphones, the company has go a mile in manufacturing of other devices involving current technologies.

Smartphones

Xiaomi has become popular due to its vast manufacture of smartphones. However, since its first smartphone it has produced many other smartphones.

Xiaomi Mi 1

Being the first to be produced by the company, it has several features, which include:

  • A resolution of 480×854 pixels
  • Four inch display screen
  • Its battery size is 1930mAh
  • ROM is 4GB
  • Dual core Processor of 1.7GHz
  • Its operating system is android 4.0
  • Primary camera is 8 Megapixels
  • Front camera is 2 megapixels

The phone led to the production of many other phones. Other versions of this phone were produced such as the Mi 1 youth edition and Mi 1S that had few different features.

Xiaomi Mi 2

One of the most affordable smartphone by Xiaomi, Mi 2 came with lots of reception from most customers.

Features
  • Has a quad core processor of 1,5 GHz
  • Its random access memory is two gigabytes
  • Its primary camera is 8 megapixels while its front camera is two megapixels
  • It has a 16 GB internal storage
  • 30 inch display screen
  • Has a resolution of 720×1280 pixels
  • Its battery capacity is 2000mAh
  • Android version is 4.1

It also has Wi-Fi connectivity and it is 3G enabled. Same to Mi 1 the Mi 2 also has other versions like Mi 2S and Mi 2A.

From these two smartphones, there are other types of Mi like Mi 3, Mi 4, Mi 5, and Mi6. All this have advanced features from the Mi 1 and Mi 2. Xiaomi also manufactures Note pads. They include the Mi Note, Mi Note 2, Mi Note 3, and Mi Note Pro, having a display screen of 5-7 inches.

Xiaomi is not left behind in the manufacture of internet connectivity devices. Not that popular as the smartphones but they produce quality and long lasting devices. MiWiFi is a Xiaomi device launched in 2014. Its latest model has the ability to store data of up to six terabytes. In addition, there are also Mi televisions, which are one of the smart televisions in the market.

Mi TV was introduced in 2013 its display screen is 43 inches. The television is manufactured using the latest technologies. To its software developing section, Xiaomi has an application known as MiTalk that enables users to communicate. The application is available for both iOS and Android users.

Xiaomi has also ventured in laptop manufacturing. Currently it has been able to produce a variety of laptops for example:

  • Mi Gaming Laptop
  • Mi Notebook Pro
  • Mi Notebook Air
  • Mi Notebook Air 4G

Why You Should Buy Xiaomi Devices

For a number of years buying a Chinese smartphone is seen as a fake device. Nevertheless, this has not affected legit and quality devices from Xiaomi to sell. The following are reasons why you should buy Xiaomi devices.

  1. High Definition Camera

Comparing to other smartphone manufacturing companies, their camera quality is lower comparing to Xiaomi camera quality and technology used.

  1. Cheap Devices

I know there is a perception that cheap is equivalent to low quality products but as per my experience with Xiaomi devices, they are very quality even though they are cheap. If you are looking for the quality devices, I think you should purchase one of their devices.

  1. Ability to Uninstall Apps

Many smartphone manufacturers install applications that you cannot uninstall. This is a big problem for most smartphone users. Xiaomi has considered this problem hence you can uninstall all third party smartphones applications.

  1. Fast

Do not under estimate Xiaomi devices. They are one of the fastest smart devices produced.

Conclusion

Since the introduction of smart devices manufacturing many companies have come to existence. However, no matter what the other manufacturers produce, Xiaomi is among the best smart devices manufacturing companies.

CNC Processing Techniques

by Chirag April 12, 2018
written by Chirag

Civilization has scaled its way past human labor. In big companies you are bound to find machine workers outnumbering human labor. The essence of this is to increase work output and it is all held together by Computer Numerical Control (CNC).

CNC systems are automated and this trademark has brought about an alliance with computers that program sequences for processing equipment and machine tools. While CNC was overly a manufacturing venture when it was first discovered, it has slowly found its way into the processing arena.

Traditional Processing Technology

You will find CNC Processing has completely phased out traditional processing. CNC Processing has overtaken its predecessor because traditional processing technology found it hard keeping up with precision. This new wave of processing is a well processed thought and its maneuver past vintage processing is in calculated steps.

For starters old processing technology could not keep up with processing of globoidal cam. A study done by a College of Mechanical Engineering in China will tell you to immediately resort to CNC processing.

Study on the CNC Processing of globoidal cam   

Globoidal cam, a non-developable spatial surface was normally produced via traditional processing. If you contrast the globoidal now and globoidal before, you will find that the cam on the markets is the kind drenched in processing finesse.

The study revealed the need for an upgrade in globoidal processing. An upgrade that could stand up to the required procession specific to processing of globoidal. Research followed suite giving major reference to the processing technology.

If you heed to the analysis that was executed you will see a turnover in the horizon of globoidal cam that is CNC Processing. The analysis was a background check on the existing processing equipment and the current processing technology.

At that time the processing technology was sloppy. The work turnover revealed stitches that had to be patched up. Getting down to this would switch up the processing principle in the key gradual steps of processing cam.

The research on the processing principle closely latched onto the problems which arose from the current traditional processing technology. This meant squaring down on generating cum, to its cutting, processing until finally carburizing. These processes are in sequence as is tradition with processing and made it easier to point out processing problems.

The clarion call was to fix:

  • Position deviation
  • Twice clamping

The two gravely impacted on processing. From the problems that arose, solutions were founded and they further proofed the processing technology of globoidal cam. A suitable fixture was designed to counteract the two problems that incapacitated processing of cam.

It was incorporating CNC into processing of globoidal cam. This phase was clouded by uncertainty as it was a huge switch up from traditional processing technology. It however proved to be a fast, efficient and profitable resolve and finally led to manufacturing of the qualified samples.

Applications of CNC Processing

CNC systems have taken over and some even say it is the first you have seen of a cybectronic age. CNC systems are overly electrified and this makes them suitable for one too many uses.

  • Plasma cutting. You may know plasma cutting from Star Wars and light sabers. Far from a fictional stance, CNC has heavily invested in plasma cutting. Plasma cutters need an arc to start and work besides CNC hardware.

There are plasma cutter manufacturers who build CNC cutting tables whilst others prefer an inbuilt cutter. CNC tables give manufacturers a sharp cut because the torch head is controlled by a computer.

  • CNC milling machines.When you place a work piece on a mill it will shave, cut and slice its pieces using rotary parts. In comparison, a CNC milling machine will give you greater precision than a hand mill job.

This is because incorporating CNC technology into a milling machine will allow you programming freedom. It will slice your work piece with precision of angle, depth and direction.

  • CNC Lathes. Lathes turn centers thus operate by rotating material on a spindle. You cut the work piece into a desired shape while the material rapidly turns. For perfect symmetry, CNC lathes is ideal when dealing with conical, cylindrical and spherical shapes.
  • CNC grinding machines. Grinders grate or grind material using a rotary wheel into desired shapes. Grinders, unlike CNC milling machines and CNC lathes work more easily with CNC technology. CNC grinders are easily programmable and require less precision.
  • CNC drilling machines. Precision in positioning of holes in materials is not easy. Applying CNC technology in drilling machines will facilitate precision. Moreover, CNC technology implores different drilling techniques.
  • Peck– Technique used to drill a hole in a stepwise procedure. Also called Interrupted cut drilling.

CNC drilling machines mount drill bits and cutting materials on their turret. This specification for CNC turret drilling machines allows for quick indexing and accurate positioning for drilling.

  • Welding– Friction star welding and Ultra-sonic welding.
  • Bending

These applications are affiliated with CNC because they all have a process which you can describe as a series of movements and operations. Also noteworthy is the applications are lined up with CNC machines.

Examples of CNC machines

CNC machines usually have a G-code. G-codes are any words in a CNC program which begin with the letter G. This code tells the CNC machine what type of action to perform and it makes them more relative to CNC technology.

As a result, CNC machines are able to conduct movement rapidly in between cuts. With automation, they can also send a controlled feed in an arc. Such machines are mills, lathes, drilling machines and plasma cutters.

Advantages of CNC Processing

  • Boosts production volumes. The precision, design and specification parameters of CNC technology is impeccable. This translates to constant huge work turnovers on a flexible scale.
  • Creates flexibility in processing. Conventional processing is unlike CNC processing. CNC processing creates uniformity and thus products match.
  • Facilitates complex tasks. Incorporating CNC into processing allows for versatility. As a result, you can create virtually any form from a material.

Disadvantages of CNC Processing

  • CNC Processing can be viewed as a strategy to make conventional processing obsolete.
  • It is

Conclusion

CNC is more like the Starbucks of processing. It’s affiliation with computers tons down processing to help achieve not just a high work turnover but also increased productivity. Even though conventional processing is affordable, CNC Processing is a bang for your buck.
