What are the advantages and performance of ABS injection molding for battery shells?
Flame-retardant ABS plastic is usually used for battery shells. ABS is a thermoplastic polymer material structure with high strength, good toughness and easy processing and molding. It has good moldability, and the surface of the processed products is smooth and easy to dye and electroplate. It can also be mixed with a variety of resins to form a blend, with high strength, light weight, non-toxic and tasteless, and is a good engineering material. Since batteries will generate a certain amount of heat during use, ABS has the problem of flammability and is unsafe at high temperatures. In addition, the existing batteries are heavy and the ABS battery shell is thick, which increases the overall quality of the battery. Therefore, the shell needs to have certain high temperature resistance.
Flame-retardant ABS plastic is a composite material made of three monomers: acrylonitrile, butadiene and styrene. It has high impact strength and chemical corrosion resistance, can effectively protect the internal structure of the battery, and ensure the safe and stable operation of the battery.
During use, the material of the battery shell can also affect its life and performance. High-quality flame-retardant ABS plastic has high wear resistance and corrosion resistance, which can extend the service life of the battery. In addition, the thickness and structure of the shell will also affect the durability and pressure resistance of the battery, so it is also very important to choose a shell material with good quality and reasonable structure.
HUIWEN PLASTIC PARTS Inspection of the process of producing energy storage battery shell:
① Product appearance inspection of energy storage battery shell: Under standard light source, visually inspect the product at a distance of about 40CM, and the product has no scratches, Deformation, weld line, scorch, perforation, impurities, color streaks, whitening, protrusions;
Product matching of battery shell: the upper cover and the bottom shell match well, can be gently removed by reversing, and match the cover plate flatly;
③ Impact test of battery shell: height 1 meter, steel ball weight 1000 grams, no cracks or damage at room temperature;
④ Internal stress test of battery shell: carbon tetrachloride infiltrates the four walls of the sample, then pours it out immediately, and observes the product for 5 minutes without cracks;
⑤ Product *** test of battery shell: first measure the length, width and height of the product, mark the test points, put the product in a constant temperature box at 70±2℃, keep it for 3 hours, cut off the power, open the door of the constant temperature box and cool it for 24-30 hours (to room temperature), pour out the water in the tank, immediately use a ruler to measure the length and width of the sample at the same position and record it, the product should be qualified in size without deformation.
HUIWEN PLASTIC PARTS, the factory currently produces molds and develops 100A 150A lithium battery injection molding shells, and has both flame retardant and non-flame retardant properties to suit different processing needs.
