Large sealed battery housings, still dominated by ABS engineering plastics, PVC battery enclosures have excellent flame retardant properties and better rigidity than PP, so they also occupy a certain market share. However, ABS is too permeable and
What are the main materials used in the battery housing?
Is it necessary to check the battery housing?
What are the precautions for the use of sealed battery housings?
The main varieties of plastics used for automotive battery housings are PP, ABS, PVC, etc., of which modified PP has the best performance to price ratio.
85% of battery housings made of PP material, usually PP as the main material, HDPE, elastomer (SBS, SR, etc.) for the modified plastic and add other additives to the co-blending process. Of which 80% to 90% with injection molding process, quality than hard rubber can be reduced by 50%, with high strength, low temperature resistance, good toughness, light density, long life and other characteristics.
It is very necessary to check the battery housing of the car
In fact, all kinds of parts of the car should go for relevant inspection, also in order to reduce the risk of occurring on the road, everyone driving on the road will certainly be the existence of the corresponding risk factors. This is why it is important to check all the components before driving to ensure your safety. It is also necessary to check the battery housing of the car to prevent cracks from occurring.
The sealed battery housing is used to hold the electrolyte and the pole plate, and should be made of acid resistant, heat resistant, shock resistant, well insulated and have a mechanical strength. In recent years, with the rapid development of engineering plastics, polypropylene plastic shells have been adopted.
Sealed battery housing compared with hard rubber shell, has a better toughness, thin and light wall wall thickness of only 3.5m, and rubber shell wall thickness of l0 mm or so), and the production process is simple, high production efficiency, easy to heat sealing, will not bring in any harmful impurities, beautiful appearance, transparent, the advantages of low
In the early days, the hard rubber used for the troughs, covers and other components was vulcanised rubber (sulphur content above 25%) with different kinds of fillers and accelerators. At that time natural rubber was chosen, and after the 60s it was gradually replaced by synthetic artificial rubber. Apart from the large-capacity starter batteries, which are still in use today, the battery compartments of all other product categories are made of plastic. We will not go into details here.
FHZL has achieved three firsts among its Chinese peers: the first successfully launched the binder jet sand 3D printer, the first utilized its sand 3D printer to foundry applications and the first exported the sand 3D printer to the overseas market. After nearly 20 years’ hardworking, FHZL has become an expert in Rapid prototype and batches manufacturing of metal parts (abbreviated as “RM” division) and Additive 3D printer Equipment manufacturing (abbreviated as “AM).
