●Place of Origin:Fujian, China (Mainland)
●Shaping Mode:Plastic Injection Mould
●Product Material: All kinds of Plastic raw material
are moulded, typically pelletised raw material is fed through a hopper
into a heated barrel with a reciprocating screw. Upon entrance to the
barrel, the temperature increases and the Van der Waals forces
that resist relative flow of individual chains are weakened as a result
of increased space between molecules at higher thermal energy states.
This process reduces its viscosity,
which enables the polymer to flow with the driving force of the
injection unit. The screw delivers the raw material forward, mixes and homogenises the thermal and viscous distributions of the polymer, and reduces the required heating time by mechanically shearing the material and adding a significant amount of frictional heating to the polymer. The material feeds forward through a check valve and collects at the front of the screw into a volume known as a shot.
