2. Description

Numerous nonferrous alloys, cast irons, powder-metallurgy and plastics are used in the manufacture of gears. However, steels are most commonly used because of their high strength-to-weight ratio and low cost. Plastic is commonly used where cost or weight is a concern. A properly designed plastic gear can replace steel in many cases because it has many desirable properties, including dirt tolerance, low speed meshing, the ability to "skip" quite well[26] and the ability to be made with materials that don't need additional lubrication. Manufacturers have used plastic gears to reduce costs in consumer items including copy machines, optical storage devices, cheap dynamos, consumer audio equipment, servo motors, and printers. Another advantage of the use of plastics, formerly (such as in the 1980s), was the reduction of repair costs for certain expensive machines. In cases of severe jamming (as of the paper in a printer), the plastic gear teeth would be torn free of their substrate, allowing the drive mechanism to then spin freely (instead of damaging itself by straining against the jam). This use of "sacrificial" gear teeth avoided destroying the much more expensive motor and related parts. This method has been superseded, in more recent designs, by the use of clutches and torque- or current-limited motors.

At present, our factory has become the base to produce electro-tricycle and its parts depending on advanced welding, spray painting and drying equipment, as well as one group of advanced and qualified technologist and managers possessing abundant professional knowledge and practical experience.

Customized products:

Generally speaking, the electric vehicle's color is customized. At the same time, we can make a change according to customers' reasonable suggestions.

Support on sales:

Welcome enquiries from all over the world. We would like to send you best quotation according to your requirements.

Technical service:

If customers have bought our car and encounter some difficulties in assembling the electric vehicles, you can associate with our customer service staff. They will help you solve these problems. If so, the problems still have not been solved, our factory will send our technicists to you to find the problems and solve it.

Quality control

With our comprehensive inspection methods, our quality control covers the material of the wire, weight of spare parts and so on. Before the shippment, we will inspect each products and take photos of it. This will ensure the products are sent to customers correctly.
