DEYING is a professional manufacturer of bulletproof helmet molds, Kevlar helmet molds, UHMWPE helmet molds, etc., and has very rich experience in this area. If you have any needs in this area, please contact us!
DEYING mold selects H13 mold steel, which is tempered and nitrided. The workpiece has good comprehensive mechanical properties, large rigidity and small deformation. Later, the inside and outside are chrome-plated and mirror polished. Good flatness, high precision and easy demoulding. The mold hardness can reach 55HRC, which greatly enhances the life of the mold.
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.
