模具硅橡胶用途： 

模具硅橡胶主要用于玩具、工艺礼品、花纹精细的产品、包模、灌注模具产品 、POLI工艺品、树脂工艺品、灯饰、蜡烛,等工艺品的复模及精密的模具制造。 

模具硅橡胶特色：   

模具硅橡胶620，具有优异的流动性，良好的操作性，不变形、耐高温，不膨胀,拉力好，撕裂强度好，翻模次数多，可反复使用，适合精密细小或复杂花纹的小件产品.并且容易脱模,收缩率可以达到千分之二。
模具硅橡胶操作： 

硅胶模具有三种开模方式：包模，涮模，灌注模。包模操作方法：模具硅橡胶是流动的白色液体，分两二组：Ａ组是硅胶，Ｂ是固化剂，例如１００克硅胶加入２％固化剂搅拌均匀，倒入围好的模种里面，放到抽空机进行抽真空，抽完真空让模具硅胶自然固化． 

Usage:For large size products, master mold design, electronic product printing positioning. Description:

HY-628 manual mold silicon rubber is flowing liquid with consistent quality in whatever color. It consists of two components, component A is silicone rubber, and component B is curing agent or catalyst. Firstly,prepare the master mold or the product to be duplicated, take certain amount of the silicone rubber, add 2-3Percent curing agent, and mix them evenly for use,a mold can be obtained in 2-3 hours. The mold with resistance to deformation and linear shrinkage and high temperature can be used repeatedly to provide fast duplication, and it with low shrinkage up to 2. The 628 manual molding silicon is mainly applicable to manual molds and small quantity of product duplication.

Applications:

The 628 silicone rubber is mainly applicable to manual mold design, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc.

Operation Instruction for Manual Mold Silicone rubber:

1. The manual mold silicon is applied to small products or products with fine patterns. The mold  for the fine detailed and small products should be made of soft silicon to protect the products from easy breaking when demoulding.

2. If large product duplication or fabrication, the mold should be made of higher hardness silicone rubber so that the products made will not deform.
