Special silicone products difficult to stripping solution
For machining special material of silica gel products, product sticky resulted in the molding process of mould is difficult to clean the burrs and products.
Greatly reduce the efficiency of our production.
And some of the more special products often stick can appear the phenomenon of mold, such as some degree of hardness is low, such as some shapes in sticking mold product, not too big not too small general mold can open one hundred to point products, hardness at about 30 products, and so on will appear to the phenomenon of mold release, there are many separation after the mold, the cutting edge and fracture resulting product stick mold core need to deduct the phenomenon of one by one, what are the reasons which cause?
In silica gel forming silica gel process for stripping is also have certain skills, such as mould temperature reached after the first mould without stripping injection water, sulfide it must be stick mold, so a lot of silicone products manufacturer must all know that the first mould release agent, release agent will be dedicated to the product of the demoulding, the appropriate spraying in the mold sticking mold parts, mold release agent is made up of different chemical resin main or styrene and amine, so there is a certain concentration, general mould release agent is not need too thick, so you can add a part in the release agent water blending into a suitable concentration, otherwise the product will appear as well as the weld mark and flow mark.
Difficult to release from the mold to the cause of problems, first of all, just open a new mould need to be sand in case a burr or mold sundry goods and so on, so the sand in the first test.
Second in the mold of the understanding on the edge of the exhaust slot and the mold core from the cutting edge is accurate, the development of the mould is reasonable, such as product is difficult to release or mold release products appear separation or edge phenomenon that will have to look for problems with temperature, the temperature of the molding machine units are commonly lower die is a little lower than the upper die temperature, can be appropriate modulation, non-stick upper die products, mold release under the water in the upper die spray mold spray less, secondly in control as far as possible when put the raw materials to the appropriate weight.
