According to the manufacturer of Automotive plastic part, engineering plastics have played a vital role in the improvement process of automobiles.

In order to meet the requirements, the resin materials used have high functions in many aspects, such as high heat resistance, dielectric breakdown strength, material strength, fluidity during molding, and low outgassing. It is about heat resistance. In the IPM manufacturing process, everything has to go through a soldering process. The surface temperature of the resin is very high, which requires the resin material used to be able to withstand it.

As a molded product of LAPEROS LCP resin, the IPM shell has a large size that has never been seen before, and its accuracy requirements are almost the same as those of small parts such as connectors currently used. In addition, on the IPM shell, there are many copper sheets called busbar crosses, and the resin covers the network of these crossed copper sheets, so the composite material with the metal meets the requirements of combined molding without the use of adhesives.

LCP molding products face the problem of fusion strength. During the IPM manufacturing process, it is necessary to ensure that the fusion part does not crack when heated. The flow analysis data provided by Baoli Plastics Technology Solutions has played a great role in solving this problem. In fact, the large parts of LCP have little accumulated data, and it is difficult to fully meet the demand. Autonomous driving has an increasing demand for high-speed and high-frequency transmission components of automobiles.

Due to the high development of ADAS, the control functions of some actuator components have been automated, so related products are required to have high operational reliability. Therefore, more and more redundant considerations are emphasized in the design, such as dividing the power supply circuit and the signal circuit into two systems and so on. This change puts forward high requirements on reliability, requiring actuator components, even if installed in a harsh environment, it cannot fail. The application of this resin to these components also requires high reliability and long life.

PBT with hydrolysis resistance can meet the harsh application environment of actuator parts

The ambient temperature under the car is very high and will be exposed to water and deicing agent, which is an environment where metal parts are prone to rust. Iron will not only corrode and rust, but also produce alkaline substances when it rusts. This contact between the alkaline substance and the resin part may cause stress cracking of the resin. In order to prevent this kind of stress cracking, it is necessary to take any of the following measures: ① Use alkali-resistant resin; ② Take anti-corrosion measures for metals. 532AR grade alkali resistant substance, even if the metal rust liquid contacts the resin, it is not easy to cause stress cracking. It is very suitable for the parts installed under the vehicle
