        【 in in 线讯】 plastics products application day 益广泛, is plastics mold provide vast market has 关方面 forecast, mold market trend is toward upper, in future mold market in, plastics mold development speed degree will high its it mold, in mold industry in ratio/proportion will improve/increase. plastics products development, plastics mold as conditions add complex and 苛刻, from belt/tape plastics mold material fast speed development, main/primary performance is full scope/range inner plastics mold material development speed degree add fast, product types speed increase. currently plastics mold material still is 主.

         plastics mold, is plastics processing industrial in and plastics molding machine sleeve/set, plastics products 以完整构 type and dimensions tool. due to plastics product types and processing methods more, plastics molding machine and plastics products structure also 繁简不一, therefore, plastics mold types type and structure is multiple more 样.

        随 automotive manufacturing and IT manufacturing 业 飞 speed development, for plastics mold industrial requirements is 越 越严格, therefore is plastics mold industrial development provide large force. 至2015 year mold industry value will breakthrough 2万 100 million yuan.

         according to molding methods different, can separation for different process requirements plastics processing mold type type, main/primary has injection molding mold, extrusion molding mold, thermoforming molding mold, high foaming polystyrene (PS) molding mold and other.

        1, plastics injection (塑) mold.

         it main/primary is thermoplastic property plastics parts product production in application most is 普遍 一 types molding mold, plastics injection mold for processing equipment is plastics injection molding machine, plastics in injection machine add hot material inner hot melt, rear in injection machine screw or 柱塞推动 lower, injection 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 material usually using/adopting plastics mold block, commonly used main/primary is carbon structure 钢, carbon tool 钢, alloy tool 钢, high speed and other. 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 machine 械, electrical appliances, 交通工 tool parts and other is use injection mold molding, it is plastics products production in application most 广 一 types processing methods.

        2, plastics compression molding mold. 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. pressure shrink mold use molding certain thermoplastic property plastics difficult melt thermoplastic property plastics (如 poly add fluorine ethylene)毛坯(cold pressure molding), optical property can very high resin sheet/slice, light micro foaming acid fiber automotive direction and other. 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.

        3, plastics 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, plastics blow molding mold. is 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 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.

        5, plastics thermoforming mold. is 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.

        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.
