硅膠手板模型是重要的一種手板材料。很多產(chǎn)品中都需要用到硅膠產(chǎn)品。那么硅膠手板模型加工注意事項有那些呢？下面濟(jì)南手板廠家就來為大家進(jìn)行介紹。

Silicone prototype is an important prototype material. Silicone products are required in many products. What are the precautions for the processing of silica gel prototype? Now, Jinan Prototype Factory will introduce to you.

1、模具硅膠里有很多氣泡

1. There are many bubbles in the silica gel of the mold

這種情況要依據(jù)條件來處里，在有抽真空機(jī)的條件下，先要把硅膠與固化劑攪拌均勻后進(jìn)行抽真空處理。如沒有真空機(jī)則可以適當(dāng)減少固化劑的添加量來進(jìn)行處理，比如原硅膠與固化劑的比率為4%,現(xiàn)在可以改成1%-2%。這樣前期模具硅膠膠連時間就會變慢，模具中的空氣就會慢慢排出，減少氣泡。

This situation should be dealt with according to the conditions. If there is a vacuum pump, the silica gel and the curing agent should be stirred evenly before vacuumizing. If there is no vacuum machine, the addition of curing agent can be appropriately reduced for treatment. For example, the ratio of original silica gel to curing agent is 4%, which can now be changed to 1% - 2%. In this way, the silicon gel bonding time of the mold in the early stage will be slow, and the air in the mold will be slowly discharged to reduce bubbles.

2、硅膠出現(xiàn)粘模

2. Silicone adhesive

出現(xiàn)這種情況一是因?yàn)榍捌趯δ７N（產(chǎn)品模型）沒有合理處理造成的，所以在開模前要對模種進(jìn)行處理，如模種表面比較粗燥或做很復(fù)雜的模具，一定要認(rèn)真打磨光滑清洗干凈。然后再均勻刷上脫模劑。常用的脫模劑有凡士林、洗潔精、液體石蠟等。實(shí)際操作中可根據(jù)模種的材質(zhì)涂刷不同的脫模劑。二是固化劑攪拌不均勻就倒入模具框中，脫模時一塊干一塊不干。

One reason for this is that the mold (product model) was not properly treated in the early stage, so the mold must be treated before opening the mold. If the surface of the mold is rough and dry or the mold is very complex, it must be carefully polished, smooth and cleaned. Then evenly brush the release agent. Common mold release agents include Vaseline, detergent, liquid paraffin, etc. In actual operation, different release agents can be applied according to the material of the mold. Second, the curing agent will be poured into the mold frame if it is not stirred evenly, and it will be dried one by one during demoulding.

3、硅膠模具產(chǎn)品變形

3. Silicone mold product deformation

這個要依據(jù)產(chǎn)品的大小來分開處理，原則上是產(chǎn)品的大小尺寸與所使用硅膠的硬度成正比。若是小件產(chǎn)品或非常精細(xì)的產(chǎn)品可以使用很軟的硅膠來開模，硬度一般在10-20度，這樣會好脫模，還不會破壞精細(xì)產(chǎn)品的紋路。

This should be handled separately according to the size of the product. In principle, the size of the product is proportional to the hardness of the silica gel used. For small products or very fine products, very soft silica gel can be used to open the mold. The hardness is generally 10-20 degrees, which will facilitate demoulding and will not damage the grain of fine products.

若是大件產(chǎn)品比如大于50公分的產(chǎn)品就一定要使用硬度為40-50的硅膠來開模。這樣才不會變形。

For large products, such as products larger than 50 cm, silicone with a hardness of 40-50 must be used to open the mold. This will not deform.

若是做很大而且又很精細(xì)的產(chǎn)品可以使用硬度為30度左右的硅膠來開模（方法是刷一層硅膠蒙上一層玻璃纖維布再刷一層硅膠），外面可以用石膏，玻璃鋼（即不飽和樹脂+玻璃纖維布）來做外膜，以此來保護(hù)的產(chǎn)品不變形。

For large and fine products, silica gel with a hardness of about 30 degrees can be used to open the mold (the method is to brush a layer of silica gel, a layer of glass fiber cloth, and then a layer of silica gel). Plaster and glass fiber reinforced plastic (i.e. unsaturated resin+glass fiber cloth) can be used outside to make the outer film to protect the products from deformation.
