SHE100B Bakelite Injection Molding Machine

SHE100B Bakelite Injection Molding Machine

Series :Bakelite Injection Molding Machine

Brand :SANSHUN

Model :SHE100B

Applications :For making bakelite

SANSHUN Machinery is one of the top 10 Chinese injection molding machinery manufacturer. We are manufacturing different types of injection molding machines, injection blow molding machine, and Auxiliary equipment. Our machines had been exported to more than 60 countries.

Characteristics
Sanshun Machinery manufacturing special Injection molding machines for Bakelite products. Bakelite has a number of important properties. It can be molded very quickly, decreasing production time. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity and prized for its low conductivity. It is not flexible. These characteristics made Bakelite particularly suitable as a molding compound. For Bakelite injection molding, the barrel temperature is set to 70-90'C to heat (with screw shear) the raw materials flowing. The screw is only for compressing and delivering the material into the mold, without melting it. Mold is heated to a temperature (180'C, for instance) to cure the raw materials
Screw configuration - The compression ratio of the screw for bakelite is 1:1 whereas for thermoplastics it's about 1:3-1:4.5
Process - Molding of thermoplastics involve melting whereas in the molding of bakelite only the fusing takes place between particles and no melting is involved.

Advantages
Energy Saving, Easy processing operations, specially designed Screw & Barrel, High Efficiency, Less production time, Automatic Mould adjustment.
