Shanghai Daoqin Plastics Co., Ltd.

当今 market upper, plastics pipe/tube product types type more, dimensions, and applications same. types type type plastics pipeline will according to types type type features application different production process, optimization cost, production rate and 运营. types plastics pipeline manufacturing process has its advantages and disadvantages. Euro Plas will review currently used for processing product 3 types methods.

  industrial in use certain type type plastics tube/pipe

I.  plastics pipe/tube is use what process manufacturing?

how to made as plastics tube/pipe is very more 人问 一 issues. 今天, technology development, 越 越 more plastics pipe/tube production methods 应运而生, meet/satisfy many field/area demand. plastics pipe/tube production 线越现代化, product quality and price 就会越 good.

1. plastics pipe/tube extrusion

this is manufacturing plastics pipe/tube most commonly used methods. plastics extrusion process below/following 5 main/primary steps:
 - 第1步: will raw materials plastics pellets and additives material 斗. plastics 会逐渐 from material 斗进入油箱

- 第 2 步: material in screw will mixed combined resin and additives will its full toward front 推. meanwhile material will plastics add hot formed liquid 体

- * 3 步: rear, sheet/plate will liquid plastics. sheet/slice has remove liquid plastics in 任何异 material. rear liquid in mold front through material tube/pipe

- 第 4 步: will liquid plastics mold in, solid 定 需形状 plastics tube/pipe

- 第 5 步: from mold in 取出, plastics tube/pipe will cooling 以永久塑造 tube/pipe 形 

一 strip/profile plastics pipe/tube extrusion production 线

advantages:
- production cost low
- easy control as process
- 一致 product quality
- ratio other methods more resistant use
- can large amount production
 
disadvantages:
- a large amount of plastics
- machine system versus heavy, difficult 以自动化
- 操 as tips/techniques large effect/influence product quality

2. plastics pipe/tube mold

一 types mold machine

advantages:
- more plastics can heavy new used for production
- for mold and dimensions has made, therefore can production complex and large dimensions plastics pipe/tube.
 
disadvantages:
- 铸造 product process versus long, therefore can other methods that 样连续 large amount production

3.  plastics pipe/tube injection molding

- 夹紧: through 夹紧两 semi mold 准备一 循 ring - injection: mold good rear, will add hot formed liquid plastics pellets through nozzle injection to mold in. - cooling: plastics mold rear, cooling, make parts is solid solid its 形状. - 拆卸: product cooling rear, injection molding mold, product by 释放, from mold in elastic 出. mold will clamping is lower 一 循 ring 做准备

PVC injection molding machine

advantages:
- can pressure very more fine product
- high degree
- product quality stability
- 冲 pressure cycle fast, can large amount production
 
disadvantages:
- high production cost
- complex injection molding mold structure
- 挤 pressure process must 持续监控, very easy effect/influence product quality
