Liquid silicone with excellent transparency, resistance to tear strength, resilience, yellow degeneration resistance, thermal stability, water resistance, good permeability and heat aging resistance and weatherability, moderate viscosity, good fluidity at the same time, convenience of operation, products high transparency.
In recent years, liquid rubber seals
injection molding method (
, that is, liquid silicone rubber injection molding to obtain the widespread popularization and promotion.
Recently, this method has a short period of time can be because of the advantages of automatic molding and plastic composite, became the molding method of common concern to the personage inside course of study.
Under the latest developments of liquid silicone rubber injection molding, and is suitable for the molding method, we give a brief introduction of material.
If use a word to explain the LIMS (
Liquid silicone rubber injection molding)
, is the addition type liquid silicone rubber with pump to the injection moulding machine, curing method in the model.
From these two methods of process flow and the difference of curing reaction, there are a few points: the advantages of LIMS (
Save manpower, material transporting, metering, mixing, injection process to achieve continuous automation, such as reducing power consumption.
Can improve the production efficiency, through rapid solidification to further shorten the molding cycle.
To improve the quality of our products: no reaction by-products generated, no impurities mixed with.
Suitable for composite forming: good liquidity in the material, the molding pressure is low, and the curing temperature range wide, therefore, can be carried out in addition to able to insert molding compound shape.
About the full automatic molding process, people from many aspects, such as injection machine, mould, materials were studied.
It's not just on the process operation can save manpower, and because it won't create useless curing, so the material cost reduction, from the perspective of both environmental protection and the method also popular attention.
For automotive skeleton oil seal as miniature products molding, ask its molding cycle (
From the injection next injection)
Within the 10 s, such a short time can do it.
