Lsr Injection Molding Machine Silicone Injection Moulding Machine

In the composition of liquid silicone rubber, the role of catalyst and inhibitor is particularly important. Because liquid silica needs to undergo vulcanization reaction, catalyst is added to accelerate the vulcanization reaction. When the temperature of liquid silica reaches the vulcanization temperature, it has a very high vulcanization speed (at 200 ℃, the vulcanization speed is only 3-5s per millimeter of wall thickness), and the liquid silicone can not exist in the temperature of 40-50 ℃ for a long time (at 50 ℃, even if the vulcanization temperature is not reached, the reaction will occur slowly within 3-4 minutes). Therefore, in order to keep the temperature of liquid silicone from curing before it reaches the curing temperature, inhibitors should be added to its components. When the curing temperature is reached, the inhibitor fails and the liquid silica gel reacts rapidly.

Characteristics

1) Compared with the solid rubber molding, the liquid silica gel injection molding does not need the operation procedures such as molding, mixing, pre molding, etc., which saves manpower, material resources and energy, reduces equipment investment and floor space.

2) The injection molding of liquid silica gel can realize the automatic processing under the fully closed condition, eliminate the manual operation deviation, reduce the influence and pollution of various variable factors in the processing, and ensure the dimensional accuracy and internal quality of the product, which is conducive to the application of liquid silica gel in medical treatment.

3) Because the viscosity of liquid silica gel is very low (generally in the range of 10-1000pas), and its fluidity and processability are good, its injection pressure is much lower than that of solid rubber and plastic. Generally, the injection pressure is 20MPa, which can be lower than 1MPa in some cases. Therefore, it can produce products without flash, reduce material waste, and reduce the wear of equipment and mold. In addition, due to the good fluidity of liquid silica gel, it is especially suitable for forming large-scale products, extremely complex shape products or ultra-thin products, such as ultra-thin products with a forming thickness of 0.5mm and a length of 100mm, which is difficult for solid rubber materials to form.

4) The curing rate of liquid silica gel is very fast. During injection molding, the curing reaction can be completed in the range of 160-220 seconds to several minutes, so the molding cycle is short and the production efficiency is high.

5) The back pressure required for liquid silica gel in screw metering is very small, generally less than 1.5MPa. For some liquid silica gel materials with very low viscosity, even no back pressure can be set, which is mainly due to the good fluidity of low viscosity silica gel and the low gas content in liquid silica gel in normal operation. On the contrary, the large back pressure will increase the density of the unvulcanized silica gel and destroy the accurate measurement effect of the metering device.

6) Liquid silica gel does not shrink in the process of injection molding, but due to its high thermal expansion coefficient, it usually shrinks by 2% ~ 3% after demoulding and cooling. The exact shrinkage data depends on the material formula. From the point of view of processing, designers should consider some factors affecting shrinkage in advance.
