Excellent weather resistance, ensuring no discoloration, aging and cracking after long-term use (including thermal oxidative aging and photoaging);
Good chemical resistance, resistant to oil and household chemicals;
Formability: injection molding materials must have sufficient fluidity to ensure the molding of complex parts and improve production efficiency;
Economy requires materials with high cost performance.
Weather resistance: Weather-resistant materials, such as AES, ASA (AAS), PC/PBT (PET), etc., should be selected for parts that are not painted or electroplated for Petrol Car;
Heat resistance: Due to the low ambient temperature, the standard heat resistance level can meet the requirements;
Low temperature resistance: The material is required to have a certain degree of low temperature resistance to prevent components from cracking in low temperature environments in winter;
Chemical resistance: prevents corrosion from oil and acid rain;
Scratch resistance: The material is required to have a certain surface hardness and a low friction coefficient to prevent scratches.
Heat resistance: Due to the long sunshine hours in summer and the high temperature inside the car, interior materials are required to have high heat resistance;
Anti-aging: including thermal oxidative aging and photoaging to prevent components from aging, discoloration and deterioration;
Odor: For the health of drivers and passengers, materials must ensure low volatility and low odor;
Matte: To ensure driving safety, choose matte material or matte leather thread;
Scratch resistance: The material is required to have a certain surface hardness and a low friction coefficient to prevent scratches and fluffing.
Without affecting the appearance and use of plastic parts, plastic parts should meet the following requirements as much as possible when designing.
(1) Metallic luster will make the original shrinkage more obvious, so uneven wall thickness of the product should be avoided to avoid shrinkage. The wall thickness should be moderate and avoid the wall being too thin, otherwise it will cause poor rigidity and the Wuling Car will be easily deformed during electroplating. , The coating has poor bonding force and is easily deformed during use, causing the coating to fall off.
(2) Avoid blind holes, otherwise the residual treatment liquid in the blind holes will not be easy to clean and will cause contamination to the next process, thus affecting the quality of Wuling Car electroplating.
(3) The plating process of Petrol Car has sharp edges and thickening. Sharp edges in the plating of Petrol Car can cause discharges, causing the coating to bulge at the corners. Therefore, rounded corner transitions should be used as much as possible, with a radius of at least 0.3mm. Flat plastic parts for Petrol Car are difficult to electroplat. The middle part of the plated part is thin, and the closer to the edge, the thicker the plated part. The entire plated part is uneven and should be Change the flat shape to a slightly rounded surface or a matte surface made from orange peel. The larger the electroplating surface area of Petrol Car, the greater the difference in gloss between the middle and the edges. A slight paraboloid can improve the gloss uniformity of the electroplating surface of Petrol Car.
