What is the silicone injection molding machine output way?

Time:2015-9-21 From:http://www.hc-machine.com/1_product.html

Through the efforts of technical team, now have a silicone cold runner mold, it is commonly used in horizontal liquid silicone injection machine, good reduced the amount of raw materials, reduce the production cost.
        1.The characteristics of liquid silicone
        Liquid Silicone (Liquid Silicone Rubber) is a non-toxic, heat resistant, high recovery of solid materials, mainly its rheological line is generally low viscosity, fast curing, shear thinned and thermal expansion coefficient.
It is characterized by excellent thermal stability, cold resistance, good electrical insulating properties, combustion can't appear toxic substances, etc.So in health supplies, car, baby supplies, medical supplies, kitchen utensils, and seal manufacturing is essential in the design of materials, and so on.
        2.Molding process
        LSR is A two-component liquid material, can have the part A and part B, the operation of the mixer to part A and B with precise 1:1 ratio completely mixed.Because some products are colored design, equipped with color pump group and color measurement area.A + B component, color, etc to plasticizing system after completely mixed.When using cold runner system, pay attention to port to fully cold.Could put an end to leak adhesive, needle valve used in the mold parts appearance, shoot rubber at the end of the needle valve quickly closed mouth.
