jewelry casting mold making silikon rubber is generally named as twopart addition

silicone rubber that vulcanizes at room temperature. Part A is a flowable liquid,

part B is the curing agent (platinum catalyst). It features an exceptional fluidity,

good operability, excellent physical properties and very low shrinkage.

The mixing ratio between Part A and Part B can be 10:1 or 1:1.

Main application of liquid silicone for jewellry or jewelry mold making

Food mold making (chocolate mold, cake mold etc. )

Rapid prototyping (urethane casting/silicone tooling/vacuum casting)

Concrete molding /cement products

PU resin casting

General Mold making

Superior manual mold design

OPERRATING INSTRUCTION of liquid silicone for jewellry or jewelry mold making

1.Stir part A and part B with right mixing ratio

evenly. And get the mixture for vacuum-

FAQ

Why is the appearance of the finished mold striate and unsmooth?It is because the appearance of the product or the model itself is not perfect, and it has not been polished before
the further operation. So when you make silicon molds, firstly you should polish the product, spray the mold spray
evenly on the product. In this case, the problem can be avoided.
