3. in or screw add pressure lower material material by pressure shrink toward front 移动, through machine front 射嘴以 very fast speed degree relatively low temperature degree combined mold cavity inner;

4, time cooling type rear mold products.

02

extrusion

借助 screw or 柱塞 挤 pressure function, make hot melt polymer/macromolecule material in pressure lower, strong/high through machine mold molding is tool has 恒定截面连续 type 材. currently extrusion molding products plastics products amount 1/3 above.

03

旋转 molding

also rotational molding molding, 旋塑, 旋转模塑, 旋转铸塑, molding and other, molding methods is will amount plastics (liquid or powder material) to add mold in, in mold combined rear, make 之沿两垂直旋转轴旋转, meanwhile make mold add hot, inner plastics raw materials in heavy force and hot can function lower, uniform coating 布, melt viscous mold cavity surface upper, molding is and mold cavity same 形状, again cooling type, demolding made 需形状 products.

04

blow molding

也称 in blow molding, is types development speed plastics processing methods. thermoplastic property resin extrusion or injection molding to tube/pipe plastics type 坯, hot （ or add hot to soft 化状态）, for mold opening in, rear in type inner pressure shrink gas, make plastics type 坯吹胀而紧贴 in mold inner upper, cooling demolding, to various in products.

05

thermoforming

一 types plastics processing process, main/primary principle is will plastics hard sheet/slice add hot soft rear, using/adopting true 空吸附于 mold surface, cooling rear molding, used for 各行各业 一 types technology process.

06

模 pressure molding

also pressure made molding or pressure shrink molding, is will powder 状,粒状 or fiber plastics molding temperature degree lower mold type in,然 rear add pressure make its molding solid as 业.模 pressure molding can used for hot solid property plastics, thermoplastic property plastics and 橡胶材 material.

07

calendering molding

is will thermoplastic property resin add hot to viscous temperature degree formed is melt 体, through above 平行异 toward 旋转辊筒间隙, make melt to 辊筒挤 calendering 展, tensile function formed is tool has specifications dimensions and combined quality requirements sheet/slice products, cooling rear molding.

08

foaming molding

is in foaming material （PVC, PE and PS and other ） in add 入适当 foaming agent, make plastics generate micro structure process. has hot solid property and thermoplastic property plastics can made formed foam plastics, foaming molding already formed is plastics processing in important field/area.

09

缠绕 molding

process is will resin liquid fiber （ or belt/tape, 预浸纱） according to 一定规律缠绕 to upper, rear solid 化, demolding, obtain products .

10

lamination molding

is in add hot, add pressure lower more same or different material combined overall molding processing methods. used for plastics processing, used for processing.

11

coating molding

is utilizing property solvent or has machine solvent coating and or and other surface, made formed leather products, or plastics and other, or will powder plastics coating and metal surface process. Common plastics coating products has 人造革, 漆布, plastics and various metal coating products.

12

浇筑 molding

is plastics processing types methods. 早期 浇铸 is in at atmospheric pressure will liquid mono or poly material polymer mold inner, polymerization solid molding formed and mold inner 腔形状 same products. 60 year 代出现 nylon mono 体浇铸见 polyamide (PA) molding technology development, 传统 浇铸 concept has 改变, polymer solvent liquid, dispersion polyvinyl chloride (PVC) and melt can used for molding.

13

滴塑

technology is utilizing thermoplastic property polymer/macromolecule material tool has can features, in conditions lower tool has property, normal temperature lower also can solid features, use methods and 专门 工 tool 喷墨, in its 黏流状态 lower requirements formed design 形态, rear in normal temperature lower solid molding.

14

cold pressure 模塑

is pressure shrink 模塑 一 types. and pressure shrink different is in normal temperature lower make material material add pressure 模塑. demolding rear product can again add hot or chemical function make its 熟化.

15

pressure shrink method

main/primary used for hot solid property plastics products production . molding add hot make its 熔化, add pressure 冲模, again add hot crosslinked solid 化, demolding rear products.

16

resin 传递模塑

is will resin to combined mold in lubricating reinforcement material solid process methods. technology can use material, hot pressure 罐, has reduce equipment cost, molding cost.

该项 technology in recent years development very fast, in machine industrial, automotive industrial, industrial and other field/area application day 广, research development 出RFI, VARTM, SCRIMP, SPRINT and other multiple separation 支, meet/satisfy different field/area application demand.

17

挤 pressure

is use or for in in material add pressure, make generate property flow, from obtain versus mold type or 凹凸模形状 made parts types pressure processing methods. pressure 时, material generate toward pressure force, make is property relatively low material, can by pressure formed 形.

18

hot molding

is types will thermoplastic property plastics sheet/slice processing formed various products relatively plastics processing methods. will thermoplastic property plastics sheet/slice processing formed various products types relatively plastics processing methods. sheet/slice in frame upper add hot to soft 化状态, in outer force function lower, make its mold type 面, and type versus 仿 形状. cooling type rear, 经修整即 formed products.

19

手糊 molding

also 称手工裱糊 molding, molding, in coating good demolding agent mold upper, using/adopting as 业, 即一边铺设 reinforcement material, coating resin to plastics products thick degree is 止, rear through solid and demolding plastics products this formed process.

20

激 light fast speed molding

（LaserRapidPrototyping: LRP） is will CAD, CAM, CNC, light, precision 伺服驱动 and new material and other technology formed types full new manufacturing technology. and manufacturing methods versus ratio tool has: type made property, property high; manufacturing process and manufacturing type 几何形状无关; processing cycle short, cost low, generally manufacturing use reduce 50%, processing cycle shrink short 70% above; high degree technology formed, achieve design manufacturing 一体化.

21

熔 melt molding method

(FDM,Fused Deposition Modeling), this type of process is through will filament material thermoplastic property plastics, wax or metal filament from add hot nozzle extrusion, according to parts 每一层 预定轨迹, solid speed rate melt 沉积.

22
