Silicone rapid prototype is a kind of silicone product mainly used for making hand molds. The rapid prototype silicone series silicone is a kind of flowing liquid. No matter what color it is, the quality is actually the same. The rapid prototype silicone has low viscosity and good fluidity. Operation, so it is commonly used to make various silicone models. The main requirements of silicone prototypes are: no shrinkage, no deformation, and hardness suitable for less complicated products. But most people don't know the content of the silicone hand model making process, so the Xiehe rapid prototype manufacturer will give you a brief introduction.

Silicone prototypes are used to make prototype models, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy crafts, plastic toy crafts, gift stationery, large statues, cultural relics reproduction, sole mold manufacturing, pad printing positioning, electronic equipment shock resistance, etc. . For large-scale products, hand model design, electronic product pad printing positioning, model design, the number of mold flips is about 5-10 times. It is used to make simple pattern products, toys, and cars. The main requirements: no shrinkage, no deformation, hardness Suitable for less complicated products.

Silicone hand rubber operation:

Silicone hand rubber is a flowing liquid, component A is a flowing liquid, and component B is a curing agent. First process the model or copied product, take a certain amount of colloid, add 2-3% curing agent, stir well and then use it, and the mold can be cured and formed within 2-3 hours.

Silicone prototype production process:

There are package mold, brush mold (segment mold, three-dimensional mold, flat mold) and pouring mold to open the prototype silicone mold, which is determined according to the size of the product.

1. Molding: First, wrap a layer of soil with a thickness of 3~5mm on the mold to make a gypsum coat, remove the soil stains and release the mold, pour the stirred silica gel and curing agent into the gypsum coat with the mold, curing and forming.

2. Mold brushing: Generally, the three-layer brushing method is multi-layered according to the mold requirements, and one layer of brush is used to vacuum the mold and brush it in place. The second layer of gauze. The third layer of cover is cured and formed.

3. Pouring mold: Pour evenly stirred silica gel and curing agent into the container surrounding the mold, vacuumize and solidify. Some molds that cannot be taken out directly need to be removed from the mold with a knife, so that the production can go smoothly.

The above content is the making process of the silicone prototype model, and I hope it can be helpful to everyone. If you want to know more about the production process of the silicone hand model, please call the Xiehe rapid prototype processing factory, we will serve you wholeheartedly.
