Shanghai Daoqin Plastics Co., Ltd.

         plastics mold, is plastics processing industrial in and plastics molding machine sleeve/set, plastics products 以完整构 type and dimensions tool. according to molding methods different, can separation is different mold types type.

        1.  injection molding mold

         it main/primary is thermoplastic property plastics parts product production in application most is 普遍 一 types molding mold, injection molding mold for processing equipment is injection molding machine, plastics in injection molding machine add hot material inner hot melt, rear in injection molding machine screw or 柱塞推动 lower, injection molding machine nozzle and mold system mold type 腔, plastics cooling hard molding, demolding to products.

         its structure usually molding parts, system, toward parts, launch machine 构, temperature system, gas system, 支撑部 parts and other separation formed, manufacturing using/adopting plastics mold 钢. injection molding processing methods usually suitable for hot plastics product products production, use injection molding process production plastics products separation 广泛, from active day use product to type complex electrical appliances, automotive parts and other is use injection molding mold molding, it is plastics products production in application most 广 一 types processing methods.

        2.  blow molding mold

         use molding plastics container type in products (如饮 material bottle, day use product and other various packaging container) types mold, blow molding 形式按 process principle main/primary has extrusion blow molding in molding, injection molding 形式按 process principle main/primary has extrusion blow molding in molding, injection blow molding in molding, injection blow molding in molding (俗称注拉吹), more blow molding in molding, sheet/slice blow molding in molding and other.

         in products blow molding for equipment usually is plastics blow molding machine, blow molding suitable for hot plastics product types products production. blow molding mold structure relatively is simple, use material more carbon more manufacturing.

        3.  extrusion mold

         use molding production 连续形状 plastics product type mold, also extrusion molding machine 头, used for pipe/tube, rod 材, Monofilament, sheet/plate 材, film, electrical cable 包覆层, type and other processing.

         and its for production equipment is plastics extrusion machine, its principle is solid plastics in add hot and extrusion machine screw add pressure conditions lower melt, 塑化, through 特定形状 口模而 made formed and 口模形状 same plastics products. its manufacturing material main/primary has carbon structure 钢, alloy tool and other, has extrusion mold in need wear resistant parts upper also 会镶嵌金 rigid and other wear resistant material.

         extrusion in process usually suitable thermoplastic property plastics product products production, its in structure upper and injection molding mold and compression molding mold has obvious difference.

        4.  thermoforming mold

        以 plastics sheet/plate, sheet/slice is raw materials molding certain relatively simple plastics products types mold, its principle is utilizing true 空盛开 methods or pressure shrink gas molding methods make solid in or upper plastics sheet/plate, sheet/slice, in add hot soft 化 情况 lower deformation in mold type upper to molding product, main/primary used for day use product, food, toys type packaging products production 方面.

         thermoforming mold molding pressure relatively low, therefore mold material more selection aluminum or non metal material manufacturing, structure relatively is simple.

        5.  compression molding mold

        包括 pressure shrink molding and pressure molding types structure mold type type. it is main/primary use molding hot solid property plastics type mold, its for equipment is pressure molding machine.

         pressure shrink molding methods according to plastics features, will mold add hot molding temperature degree (generally in 103°108°), rear will amount good compression molding powder mold type and add material 室, combined mold, plastics in high hot, high pressure function lower soft viscous 流, 经一定 time rear solid type, formed is products 形状.

         pressure molding and pressure shrink molding different is has mono add material 室, molding front mold combined, plastics in add material inner formed preheating viscous 流态, in pressure function lower adjustment mold type 腔, hard molding.

         compression molding mold main/primary type 腔, add material 腔, toward machine 构, launch parts, add hot system and other formed. pressure mold used for electrical appliances parts 方面. compression molding mold manufacturing use and injection mold basic same.

        6.  high foaming polystyrene (PS) molding mold

         is application can property polystyrene (PS) (由 polystyrene (PS) and foaming agent formed material) raw materials molding various 需形状 foam plastics packaging materials types mold.

         its principle is can polystyrene (PS) in mold inner can 入蒸汽 molding, 包括简 easy 手工操 as mold and liquid pressure machine 直通式 foam plastics mold types type type, main/primary use production industrial product packaging product. manufacturing types mold material has aluminum, 不锈钢, copper and other.
