What is the difference between silicone mold and plastic mold?

The silicone mould is divided into solid silicone mould and liquid silicone mould. The solid mould is extruded up and down by vulcanizing machine at high temperature to make the silicone inside formed, and the liquid mould is extruded by AB two needle holes for injection molding. Plastic mold is used for pressure molding, extrusion, blow molding and low foam molding of a combination of molds referred to as thermoplastic materials, generally using injection molding mold. What is the difference between silicone mold and plastic mold? Let Suzhou Jiopeng intelligent to tell you!

First, the difference between the two materials

Solid state molds are generally divided into upper and lower plates or upper, middle and lower plates, and are cured at high temperatures. It has the characteristics of high temperature resistance, corrosion resistance, strong tear resistance and high simulation precision. Silica gel is a thermosetting material, and the fluidity is good when the solidification temperature is not reached, so the silica gel mold does not need to be boiled like the plastic mold, and the mold is generally opened with 50#, P20 or 718, and the price is cheaper than the plastic mold.

Plastic mold is a combination mold for compression, extrusion, injection molding, blow molding, and low foam molding, also known as plastic mold or injection mold. The structure of the plastic mold is more complex than the silicone mold, and the steel is also better, generally 757, 718, S136, when the product volume is large, when the mold life is required, the mold can be hardened.

Second, the difference of use

Silicone raw materials can be divided into solid silicone and liquid silicone. Solid silica gel is mainly used for molding products. Such as: silicone accessories, silicone tableware, silicone mold, silicone sheath, etc., liquid silicone is mainly used for extrusion products, such as silicone pacifiers, silicone tubes and so on.

Plastic parts are widely used in every field of life today, such as household appliances, instrumentation, wire and cable, construction equipment, communications and electronics, automotive industry, aerospace, daily hardware and so on. The use of plastic is so wide, so easy to use, that it has brought side effects, in some areas people have to carry out "plastic ban".
