Silicone as a common environmentally friendly raw material, because of its many advantages and favored by consumers, its softness and safety and environmental protection performance is widely used in industrial seals and medical devices, the most important of which is its working temperature of -40~+240 degrees Celsius is plastic products can not be compared.
The use of silicone wrapped metal or plastic parts to form some new properties is to make the product soft and hard. For example, silicone coated silicone spatula, its environmental performance is loved by consumers, so what are the molding processes of silicone products produced by silicone materials?
1. Extrusion molding process
Extrusion molding process is just like we squeeze toothpaste, the head of the silicone extrusion equipment is also the cross-section shape of the product, there is a certain length, under the action of force and temperature, the product out of the machine has been vulcanized, the product processed by this process is generally a strip product, the product cross-section can be a variety of rectangular strips, ring silicone tubes and so on.
2. Glue dropping process
Silicone products can also use the glue dropping process to drop out, but this process requires liquid silicone, the liquid silicone is installed in the syringe, the raw material is dropped on the mold with pneumatic and manual operation, heating vulcanization molding, this process is a manual process, requires more labor, and the production capacity is not high. However, there is a more important feature, that is, the products made by this process can drop a variety of colors according to the requirements, and the silicone products that drop out are also very delicate and concave. What we do more is a variety of colors of silicone bracelets, a variety of color patterns of silicone phone cases, all kinds of exquisite cartoon silicone key rings and other small pendants.
