DEYING mold selling High Quality Fast Ballistic Helmet Mold,It is an earlier supplier of molding molds for military products in China
The most common modern helmets are Kevlar helmets, which are one of the modern individual armors. Compared with the old steel helmets, they have two major advantages that cannot be replaced:
1-Different from heavy metal helmets, the lightest Kevlar helmet only needs 680 grams, and the center of gravity is low. Soldiers can turn their heads to observe aiming while wearing it.
2- This kind of helmet can be said to be made of super high-strength aromatic polyamide fiber material, which is soft and rigid. Compared with the steel helmet, the anti-ballistic performance is increased by about 25%.
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured.
UD/KEVLAR product mould
UHMWPE is commonly known as very high molecular weight polyethylene. Its molecular weight can reach 1 to 5 million. It has high wear resistance, low friction coefficient, high impact resistance, and better sound-absorbing performance. Compared with ordinary thermoplastics, it has lower fluidity and is difficult to process. At present, it can only be produced by molding. Our company cooperated with the *** unit, using its good impact resistance, developed the body armor and bulletproof helmet molds, realized segmented pressurization and heating on a pair of molds, and switched the heating mold to cooling in the later stage of molding. The mold ensures that the product is cooled and shaped to the set temperature and set material hardness, ensuring that the product can be easily taken out of the mold.
