HIP Process Long Life Twin Screw Extruder Replacement Screw Elements
1. Descriptions
We are working for years about the life enlarging of the replacement parts of twin Screw Extruder Now , we can produce high quality of Bimetallic screw parts and cylinders. it will have the following charactors:
1. Using process of PM-HIP bimetallic tool steels
2. WC alloy coating and grinding. enlarge the life about 2- 5 times then normal steel
3. producing based on customer requirement, OEM production.
Screw
Screw Kneading block built on modular principle allows various L/D ratio of screw easily be changed to suit different material. Screw component made of high speed & wear-resisting steel.
Barrel
By means of the replaceable screw barrel sections, the processing sections is devided into individual zones. The barrels are heated electrically. In addition, the barrels are provided with longitudinal bores for cooling with water. Uniform temperature distribution, namely on the circumference of the eight-shaped barrel bore, is achieved by a reverse force-flow temperature control circuit. Connections of pipes for temperature control are in groove-tongue design to balance alternating thermal stress and avoid leakage.
The screw barrels are made of nitrided steel. In order to increase the service life of the screw barrels, these are provided with wear resistant inserts.
