Add too much in the process of production mold silicone oil, silicone oil destroyed the molecular weight of the silica gel, so the mold can appear the phenomenon such as fewer rolling over not durable.If do small decorative pattern more complex products, with high hardness of silica gel to open mold, can appear the phenomenon of fewer rolling over, because the silicone hard time will be very fragile, easily broken.On the contrary, if make building products with small hardness of silica gel to do the mold, the results also is not satisfied.Because the silicone is too soft, its tensile and tear ...

Mold the silicone is belong to the condensation silicone, it is by absorbing moisture in the air and curing, silica gel in the process of making the water boiled, without calling in just the right amount of moisture, can appear the phenomenon.Solution: this phenomenon does not belong to quality problems, but because there is no control moisture, improve the shelf life of silicone, long shelf life will appear some phenomenon, as long as in the use of silica gel, add 0.05% water, stir evenly can solve some conditions.

Because the customer in the process of making mould, in order to reduce the viscosity of silica gel, the silica gel easy to operate and large amounts of added silicone oil in the silica gel, this will make silicone is very soft, not resistant, pull, tear strength is reduced, the phenomenon of tension variation, resulting in the mould is not durable, service life is short, the phenomenon such as fewer rolling over.

Mold silicone itself is not taking oil, appeared to take oil is because of the complex silicone oil is added in the operation process with complex ligand (silicone oil and white mineral oil), because the white mineral oil is oil chemical products, not silicone oil.

In the process of making silicone mold, we suggest that the customer had better do not add any silicone oil, if necessary, silicone oil to add up to not more than 5% ~ 10%.Because the amount of silicone oil to add too much can destroy the molecular weight of silica gel, so the mold to produce not resistant to acid and alkali, not resistant to ageing phenomenon.

Appear this kind of phenomenon is not to copy products or models of grinding or polishing.Because in fact the model or the product itself is not enough smooth or perfect, so to copy products or model if without grinding or polishing, again good made of silicone mold will not beautiful, not smooth enough.Another is that playing release agent, not besmear brushs homogeneous can cause mould is not smooth.

This happens because the early to die (product model) there is no reasonable processing, so before the open mold to mold processing, such as the surface of the kind of relatively coarse or do very complicated mould, must be carefully polished smooth and clean.Then brush evenly on release agent.Commonly used mold release have vaseline, detergent, liquid paraffin, etc.Practice according to the modulus of the material of coating different release agent.

Never spray paint plastic toys or products, ten products have two at the time of printing design is not complete, also is not oil, is a normal phenomenon.For injection molding machine in the process of production of toys, each dozen products to steel surface spraying mold release agent, release agent had just spray mold first product or second product surface has a lot of mold release deposit, if this product without water or water to clean that wash a face that day, for pad printing directly, this phenomenon will emerge.
