Brief introduction of prototype mold silicone:

Prototype mold silicone is also called prototype silicone. Compared with conventional mold glue, the price is low,  the number of re-molding is  high. Generally, it may be about 20 times, while the number of conventional mold silicone re-molding can reach thousands of times. Therefore, prototype silica gel is mainly used for model development of various products  small batch production.

Shouban model mold silicone use:

Hand model mold silicone is widely used in the production of hand model molds, handicraft model design, PVC plastic molds, alloy toy crafts, plastic toys, low melting point alloy product mold production, simulation product model replication, shoe sole mold manufacturing, electronic equipment earthquake resistance, pad printing Development of product models such as positioning.

Features of hand model mold silicone:

1. Low viscosity, good fluidity  convenient operation;

2. It is  limited by the thickness of the product  can be deeply cured;

3. Low price  cost saving.

Hand model mold silicone operation:

1. The silica gel  a certain amount of curing agent are mixed according to the proportion,  the mixing can be manually stirred  mixed with equipment;

2. The mixed rubber should be defoamed before filling the mold. During the degassing process, the volume of the rubber compound will increase by 4-5 times, so the volume of the degassing container is 4-5 times larger than that of the rubber compound,  the colloid will return to normal after about 10 minutes. When no bubbles escape on the surface Time can be completed.

3. The surface of the model product  the surface of the material model to be contacted by the rubber material needs to use liquid paraffin  surfactant as a release agent.

4. The curing of the model after mixing  degassing requires a certain temperature  time, such as curing at 120±5°C for 30 minutes, curing at 60~70°C for 2 to 3 hours,  curing at room temperature for 24 hours.

Hand model mold silicone operation note:

1. After making the product with hand-made silica gel, wait for 24 hours before putting it into production;

2. During the stirring process, the silicone  curing agent must be fully stirred evenly,  the vacuuming time should  be too long to avoid curing of the silicone during vacuuming.
