With the continuous growth of China's automobile market demand, the automobile manufacturing industry keeps pace with The Times and flourishes.
Many joint venture brands generate localized production needs, and actively seek suitable partners in China;
Many domestic independent brands urgently need the cooperation of leading technology because of hybrid and electric generation development or body development.
Point of pain
Under the new situation in China, some parts of the traditional transmission and power transmission system have been increasingly unable to meet the stringent requirements of the innovation environment: high strength, high speed, low friction, high temperature environment, etc.
With the increasing requirements of transmission efficiency of gearbox, many parts originally using ordinary engineering plastics are not competent, so they are constantly replaced by high-performance plastics; Many accessories were required to be redesigned due to new application requirements. This situation is particularly prominent in the application of transmission seal rings and plastic thrust washers:
Automotive Transmission Seal Rings/Automotive Transmission Seal Rings
The seal ring must have a special shape that has been professionally designed to meet the leakage rate, pressure, temperature and speed conditions required by the OEM. These key parts are essential to enable smooth shifting of the transmission and optimize mechanical/frictional efficiency. In torque output applications, the seal ensures precise hydraulic actuation (the tighter the seal, the more precise the hydraulic control).

Plastic Thrust Washers/Plastic Thrust Washers
Thrust washers and other load-bearing components are critical to the performance of power transmission systems. They need to withstand extreme temperatures while reducing the impact of friction on the overall system. The mechanical strength and dimensional accuracy of plastic thrust washers are important to improve the performance of these high-speed, high-load applications.

HUIWEN PLASTIC PARTS, founded in 1996, is a global leader in the development of polymer materials and the manufacture of customized high-performance elastomers and thermoplastic sealing components. It has been supplying PEEK sealing rings to many automotive manufacturers for more than 15 years.
HUIWEN PLASTIC PARTS produces 20 million sealing rings per year for automatic transmission, CVT and clutch applications. We specialize in tailoring garments, designing and developing, manufacturing and processing precision thrust washers and friction resistant parts for various demanding applications such as powertrain and high torque management.
Advantages of technology
Advantage 1: Materials science
1) For: high strength + low friction
Due to the importance of mechanical strength and low friction, material selection is critical for thrust washer parts. High performance thermoplastics (bearing-grade PEEK, Torlon, Aurum, etc.) are often required in order for these parts to be used in the harsh environments within the powerline system. HUIWEN's team will calculate the PV value of the limit for the customer's application conditions, and determine the best material based on the size and processing requirements.
2) For: high temperature application environment
Through extensive research in advanced materials laboratories, MRP will ensure that transmission seals can withstand the heat and pressure generated by automatic transmissions and other torque management systems; And further study the influence of material structure, characteristics and processing on product characteristics, as well as the relationship between the performance of materials in the application, so that the product performance can achieve perfect application in the high temperature environment.
Advantage two: mold and manufacturing
High performance plastics often have higher requirements for molds. They require higher molding temperatures and complex die structures to optimize process stability and reduce material waste. HUIWEN has extensive experience in injection molding of these high performance materials and is even better equipped to develop and mass produce the complex multi-cavity molds required.

Advantage three: molding and manufacturing
Engineers must analyze and optimize the injection molding process required to construct the perfect seal ring before mass production. This step is essential to optimize the location of the gate, ensure uniform cavity filling, evaluate various materials, and identify potential appearance defects. For these reasons, more engineers turn to us because of HUIWEN's superior ability to manufacture high-precision sealing rings.
Scientific injection molding methods are essential for the development of optimal injection molding processes, including continuous cavity pressure monitoring. Because the quality of the part directly affects the sealing performance, the mold is also critical.
Revenue to customers
HUIWEN, with its professional material engineers and expert team, can provide perfect solutions for the development and design of domestic automobile brands or the localized production needs of joint venture automobiles: according to the application conditions of customers, it calculates the limit PV value and selects the best materials to help customers save materials and reduce costs.
