Product Description

Auto Parts Making Machine Liquid Silicone Injection Machine For Auto Parts

Silica gel products are a kind of environmental protection, low carbon and green products processed and formed with silica gel as raw material. The main processing technologies are injection molding, extrusion molding and molding. Silica gel has other irreplaceable advantages of soft rubber, such as good elasticity, water and moisture resistance, acid and alkali resistance, no harmful substances, and not easy to deform.


Silica gel products are often used in the field of high requirements for human contact, such as baby nipples, human organs, medical supplies, etc., with a very broad application prospect. At the same time, silica gel is a non petroleum product and does not rely on the increasingly scarce petroleum resources. Therefore, silica gel products have become a substitute for similar rubber and plastic products. Among them, injection molding liquid silica gel can produce all high-temperature rubber products, with many advantages such as simple process flow, high product accuracy and large output, which will become a new trend in the next few years.


Advantages of liquid silica gel:


● non toxic, odorless and tasteless to human body;


● good transparency and can be disinfected;




Good touch, elasticity and anti-aging properties.


● good high temperature resistance and thermal stability (continuous working temperature up to 180 ° C);


● good low temperature performance (still soft at - 50 ℃);


Excellent electrical insulation, no harmful substances will be produced during combustion


The solidification reaction of liquid silica gel injection mold occurs at the mold temperature of 120-150 ℃, and the mold temperature control is very important


● the mold surface temperature shall be stable: if the surface temperature is too high, the products will be burnt, the parting line will crack, and the products will become brittle. If the surface temperature is too low, the curing speed of the compound is slow, and the product cannot be demoulded, etc;


● the temperature of the mold needs to be heated evenly: the mold is heated unevenly and the temperature difference is large, which will make the flow of the rubber material unstable and prone to the phenomenon of air block and insufficient injection;


● location of heater: enough distance shall be kept between heater and parting line to prevent formwork from warping and deformation, resulting in overflow of finished products;

The reason of affecting the life (aging) of silica gel in mould



1. In the process of mould making, improper operation leads to quality problems of products;



2. When the mold is formed, the product can be put into production directly, and the product will be damaged before its performance is stable;


3. The raw material is not good, and other ingredients are added to reduce the product performance;



4. The oxidation reaction will break the molecular chain of silica gel, reduce the function of silica gel and shorten the service life of the product;



5. The thermal effect is beyond the heat resistance range of the product, which makes the silica gel molecules split or cross-linked, accelerates the diffusion of oxygen, and results in the catalysis of oxidation reaction;



6. Light reaction is the same as heat effect. Different light wave irradiation has different effects on the product, especially UV;



7. Human factors
