Processing process of prototype silicone compound mold

The prototype silicone series silica gel is a liquid that flows. No matter what color, the quality is actually unchanged, component is liquid flowing, and component B is curing agent. First handle the molded or copied products, take a certain amount of gel, and add 2- The curing agent of 3% can be used after mixing evenly, 2-Mold can be cured in 3 hours. It has no deformation, no shrinkage, high temperature resistance, and can be used repeatedly after mold molding. It provides rapid replication for products, and the shrinkage rate of products can reach 2‰. It is mainly used for prototype models and Small Batch replication products.

The production process of prototype silica gel:

there are package molds and brush molds for opening molds (Slice mode, stereo mode, plane mode) , Perfusion mold, which is determined according to the size of the product.

1. Package mold: First pack a layer of thickness on the mold to be 3 ~ 5mm of the soil, make a plaster coat, remove the soil stains and demoulding, pour the stirred silica gel and curing agent into the plaster coat with a mold, and solidify it.

2. Brush mold: generally brush three layers according to the requirements of the mold, one layer of brush vacuum on the mold, brush in place. Gauze on the second floor. The third layer of cover surface is solidified and formed.

3. Pouring mold: Pour the evenly stirred silica gel and curing agent into the container of the good mold, vacuum curing. Some who cannot directly remove the mold must also be demoulded with a knife so that the production can be smooth.

prototype silicone features:

1, low viscosity, good fluidity, good operation.

2. The shrinkage rate is small, not deformed, and the shrinkage rate is 2. If the shrinkage is large, the products produced will become smaller, other liquids will deform

prototype silicone operation method:

1. first of all, you should handle the original model or the product to be copied. Because the product or model you copy is not polished or polished, in fact the model or product itself is not smooth or perfect enough, they are liquid flowing, component is silica gel, component B is curing agent, the mold you make with silica gel is not good enough, and the products actually filled are not smooth enough.

2. vacuum treatment, according to a certain amount of proportion, after mixing the silicone with the curing agent evenly, the vacuum treatment time should not be too long. Because the mixing time of silica gel and curing agent will generate bubbles, and if the bubbles are pumped out, the silicone mold will have a lot of air holes, which directly affects the quality of the product.

3. Pour the spare silica gel into the mold frame.

Why do many enterprises choose the extension model?

Why do you choose extension dimensions multiple times? The old customer said this:' I believe that Tuowei is because the prototype of Tuowei is good in materials, without cutting corners, with good quality and excellent service. ' This is the customer's trust in Taowei. This trust, Tuowei has the obligation to provide customers with satisfactory products and services, and is also the driving force for us to do well!
