Molds of  high quality silicon rubber for toys mod making :

HY-528# is applicable to make molds of smaller products and the production will be 2-3 pieces.

HY-540# , compared to other two types, for its moderate hardness and better quality & performance, its production will be 20-30 pieces.

HY-570# is applicable to large size products duplications and  Electronic equipment antivibration 

Features of  high quality silicon rubber for toys mod making: 

Manual mold silicone has good elasticity, non-deformation , high temperature resistance, low shrinkage. And it is suitable for manual mold design and small duplication mold production.

Operation Instruction for  high quality silicon rubber for toys mod making: 

(1)  Correct mixing ratio

Component A is silicone rubber, and component B is curing agent or vulcanizing agent, usually the mixing ratio  will be 2-3%. Such as to 100G silicone rubber should be added 2G catalyst and then mix them totally

(2) Preparation of the Original molds

Firstly, you should deal carefully with the Original mold or the products you want to be molded. (3)Vacuum-Pumping Process

To mix the silicone and catalyst with a standard mixing ratio and then do the process of Vacuum-Pumping. Bubbles will come out during the mixing of the silicone and hardener, if without Vacuum-Pumping, the bubbles cannot be released from the mixture, as a result, there will be many bubbles in the finished silicone mold. Then the mold has a less tensile strength which will affect the reproduction times. Such an unsmoothed silicone mold will affect the quality of the production directly.

FAQ of high quality silicon rubber for toys mod making: 

The solutions of the sticky of the high quality silicon rubber for toys mold?

The main reason for this problem is that you do not handle the products or original molds well, then you should deal with the original mold or products carefully before molding. Such as for the products with a complicated

pattern or a unsmoothed surface, you should polish and clean the products after which it will be molded ,then spray the release agent. Normally, the release agent can be Vaseline , detergent. liquid wax Etc. In practical process, you can bush different release agent according to different material.

The second reason is that the operator pour the silicone into the mold when the mixture is mixed evenly, then the finish silicone mold will not cure and dry entirely
