What are the protection performance requirements for injection molded automotive products?
Publish Time: 2024-08-22
The protective performance requirements of injection molded automotive products are multifaceted, aiming to ensure that the products can maintain their good performance and appearance in various use environments.
1. Weather resistance
Requirement: Injection molded automotive products need to be able to maintain stable performance for a long time under various climatic conditions, and are not affected by natural environments such as sunlight, rain, snow, ice, high or low temperatures.
Implementation method: Select materials with good weather resistance, such as specially treated ABS, PP, etc., and consider drainage, ventilation and other structures when designing products to reduce the accumulation of water and moisture.
2. Corrosion resistance
Requirement: Automotive products will be exposed to various chemicals during use, such as gasoline, engine oil, coolant, detergent, salt spray, etc., so they need to have excellent corrosion resistance.
Implementation method: Select materials with good corrosion resistance and perform anti-corrosion treatment on the surface of the product, such as spraying corrosion-resistant coating or electroplating.
3. Wear resistance
Requirement: Automotive products are often subject to friction and wear during use, such as bumpers, door handles and other parts, so they need to have high wear resistance.
Implementation: Select materials with good wear resistance, such as reinforced plastics or rubber materials, and consider reducing unnecessary friction points when designing products.
4. Impact resistance
Requirement: Automotive products need to be able to withstand a certain degree of impact and collision to ensure the safety of occupants in the car in the event of an accident.
Implementation: Use high-strength and high-toughness materials, such as glass fiber reinforced plastics or metal alloys, and make reasonable structural layout and strength design when designing products.
5. Sealing
Requirement: The sealing performance of automotive products is crucial to prevent moisture, dust, noise, etc. from entering the car.
Implementation: Ensure good sealing of the mold during the injection molding process, use high-quality seals and sealing materials, and consider the design and optimization of the sealing structure in product design.
6. Environmental protection
Requirement: With the improvement of environmental awareness, injection molded automotive products need to comply with relevant environmental standards and regulations, such as reducing the emission of harmful substances, recyclability, etc.
Implementation: Select environmentally friendly injection molding materials and additives, optimize the injection molding process to reduce the emission of exhaust gas and wastewater, and consider the recyclability and reuse of products when designing products.
7. Quality control
Requirements: Injection molding automotive products need to go through a strict quality control process to ensure that the performance indicators of the products meet the design requirements.
Implementation: Establish a complete quality management system, including raw material inspection, injection molding process monitoring, finished product inspection and other links, and strictly control key process parameters. At the same time, regularly conduct product performance tests and reliability tests to verify the quality and performance of the products.
The protective performance requirements of injection molding automotive products cover multiple aspects such as weather resistance, corrosion resistance, wear resistance, impact resistance, sealing, environmental protection and quality control. The realization of these requirements requires comprehensive efforts in material selection, process optimization, product design and quality control.
