Choosing the right injection molding material for automotive precision connectors


Choosing the right injection molding material for automotive precision connectors


Choosing the right injection molding material for automotive precision connectors is a critical decision, which directly affects the performance, reliability and durability of the connector. The following are several factors to consider when selecting injection molding materials for automotive precision connectors:
Electrical properties: Automotive precision connectors need to have good electrical properties, including conductivity, insulation and arc resistance. Therefore, the injection molding material should have good conductivity and insulation properties to ensure the electrical connection and transmission performance of the connector.
Heat resistance: Automotive precision connectors work in high-temperature environments such as automobile engine compartments, so injection molding materials need to have good heat resistance. Materials should be able to maintain stable properties at high temperatures without softening, deforming or failing.
Chemical resistance: Automotive precision connectors may be exposed to various chemicals, such as gasoline, lubricating oil, coolant, etc. Injection molding materials should have good chemical resistance and be able to resist erosion and corrosion from chemical substances to ensure the long-term stability and reliability of the connector.
Wear resistance: Automotive precision connectors may be subject to friction and wear during the plugging and unplugging process, so the injection molding material needs to have good wear resistance. The material should be able to resist friction and wear to extend the life of the connector.
Environmental protection: In the automotive industry, the requirements for environmental protection are getting higher and higher. Therefore, when selecting injection molding materials, the environmental performance of the material should be considered, such as whether it complies with relevant environmental standards and regulations.
Commonly used automotive precision connector injection molding materials include engineering plastics, such as polyamide (PA), PA66,PBT,polyimide (PI), polyetheretherketone (PEEK), etc. These materials have good electrical properties, heat resistance, chemical resistance and wear resistance, and are suitable for the manufacture of automotive precision connectors.
When selecting injection molding materials, factors such as cost, processing performance and availability also need to be considered. By comprehensively considering the above factors, select the appropriate injection molding material to meet the requirements and performance of automotive precision connectors. At the same time, it is also necessary to strictly abide by relevant safety regulations and operating procedures to ensure the safety of the working environment and the health of employees.
