Lead-tin Alloy Craft Silicone Disc Description: The disc silicone rubber consist of Past A and Part B, Part A is the working surface, Part B acts secondary role. It mainly applicable to cast lead tin craftworks and product models.Fix the product upon one piece of A, cover with another pieces of A , and put pieces of Part B over the upper and lower sides of Part A, then take it to a press molding machine, the temperature is generally at 160～180℃, and it can be demouled in 30 minutes. After take out the mold, make a round hole at the central point of the disc with diameter of 30mm for material injection, inject the lead-tin alloy liquid into the disc silicone mold,the products can be shaped by the force of a mode of centrifuge.

Lead-tin Alloy Craft Silicone Disc Features and properties:
1.Temperature resistance of 380℃～400℃ or even higher.
2.Fast cooling,easy to grinding and polish.
3. The usual sizes are 9 inches and 12 inches. Thickness is 4.5~5mm, special requirements can be customized.

Condensation silicone for mold making description

Condensation siilcone for mold making is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

Frequently asked questions of silicone rubber for mold making

The solutions of the sticky of the Condensation 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..
