Fashionable, quality, variety, wholesale and retail can I plant a professional injection steel production capacity and design development and build a variety of sizes and flower-shaped plastic color brick mold box according to user needs, using fully computerized and automated injection molding equipment and production technology. The main choice of cover plate steel mold iron welded together, with good ease, the full protection of the shroud preform normal use. Such a cover plate steel mold is often used to better meet the high-speed high-speed rail use. Shutters common mold material structure and depending on the material, divided into two categories: one is metal cover plate mold; one is the non-metal cover plate mold. Metal mold which is characterized by high cost, poor security, but because of its high capacity, good impact resistance to fatigue, and beautiful and durable, modern image of the city in line with the specific requirements, which is still the biggest usage. Non-metallic mold material is generally the case of concrete, steel fiber concrete and composite materials, which is characterized by low cost, high security, but the weight, impact fatigue resistance is poor, prone to breakage, short life, the image of the poor and not open Convenience. In the matter due to mold plastic flow to fill and suffer greater stress and friction, requiring precision molds link shape and dimensional accuracy of stability, to ensure adequate mold service life. Mold wear resistance depends on the chemical factors punishment hardness of steel and heat treatment, thereby increasing the hardness of the mold will help improve the wear resistance.
