1. Gypsum sculpture molds making silicone rubber instruction:
Gypsum sculpture molds making silicone rubber are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold
making for poli crafts, resin crafts lighting and candle crafts.
2. Applications of Gypsum sculpture molds making silicone rubber:
Gypsum sculpture molds making silicone rubber also can be applied for manual mold design, PVC plastic mould, cement product mold, low melting-point alloy mould, alloy toy crafts, plastic toy, craftwork, gift and stationery, big statue, cultural relic duplication,pad printing orientation, electronic appliances vibration resistance, etc.
3. Features of Gypsum sculpture molds making silicone rubber :
a. Good characteristics of easy-operation
b. Light viscosity and good flowability
c. Low shrinkage
d. Favorable tension
e. No deformation
f. Favorable hardness
g. High temperature resistance, acid and alkali-resistance and ageing resistance

5. Operation of Gypsum sculpture molds making silicone rubber:
If the customer want to make large products and large size molds the mold should be made of silicone rubber mold making with high hardeness On the contray, if the mold with fine and precision patterns , it should be made of silicone rubebr low hardness, the amount of the cruing agent depends on the actual requirements of the customer.
FAQs of the manual mold silicone rubber :
The solutions of the sticky of the silicone 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.
