Four or above stages precise temperature PID control for barrel.Ningbo SuRui Machinery Co.,ltd Established in 2006, Located in Ningbo City, the famous harbour city in china.

As you will run dozen tons of PET material and heated it up to 190 degree from your in-house temperature.

Nano-heating band is also an important part.

A support construction is in need to avoid the barrel is getting bended after years running.

A longer screw and barrel is need due bigger L/D ratio and adding longer mixing element.

Bigger hole of injection nozzle for PET material injection.

As most PET bottles require high transparency, high color uniformity, high gloss surface.

The mixing element is more complex and very very important.

Raw materials will become discolored or opaque due to excessive shear heat.

Low shear, low compression ratio screw is a most collection.

The Diamer of the Screw is big as the shoot weight is very big comparing to other materials.
