Emans high-performance PPA material is applied to clutch hydraulic bearing bracket, which can reduce weight and cost by more than 20%

In today's automotive market environment, strict carbon emission regulations and fierce competition together lead to rapid changes in the entire automotive supply chain. According to the study, for every 10% reduction in the weight of a car, carbon dioxide emissions can be reduced by 2.45kg. Therefore, in today's car weight loss is still a top priority.

Lightweighting of the most effective solution is through the whole car use lighter parts to lose weight, but have very strict requirements about the quality of the material, must ensure the strength of the car and at the premise of safety performance, as much as possible to reduce the weight of the vehicle, so as to improve the power performance of vehicle, reduce fuel consumption, reduce exhaust pollution.

Plastic has light weight, corrosion resistance, impact resistance, high specific strength, sound insulation, low cost and easy to process, and many other characteristics, can simultaneously meet the requirements of reducing the weight and cost of the vehicle, for the safety, comfort and appearance of the vehicle.

Among automotive components, the "clutch hydraulic bearing bracket" is an extreme load bearing component that disconnects and connects the engine to the gearbox during the gear shift.

Even short vehicle trips can require hundreds of such shifts, so OEM components need to be able to withstand millions of them, and the product needs to withstand 120bar of internal pressure. This requires that the material must have excellent wear resistance, even at high temperatures.

In collaboration with Germany's Schaefler Group, Emans developed components using Grivory HT, a high-performance polyphthalamide with ultra-high mechanical strength and heat resistance that maintains excellent mechanical strength even in automotive gearboxes with temperatures as high as 170 ° C.

In addition to the material characteristics, mold design and processing is also particularly critical. Polyphthalamide has a super high melting point of about 320℃, and can achieve the best performance at mold temperature of 140 ~ 150℃. Material suppliers and tier 1 suppliers need months of project work and continuous development and testing before they can be approved by oems.

There are now a variety of models on the streets of China, all equipped with the clutch hydraulic bearing bracket made of Iman material, which also saves more than 20% in weight and cost.
