Model 400 Corrosion Resistant Twin Screw Extruder Screw Elements For Petroleum Industry

4. Our strength

They finish machining is carried out before heat treatment, and after heat treatment, the shape of the products are uncontrolled, so they cannot control precision. Our finishing is done after heat treatment, and can eliminate deformation of the parts in the heat treatment, then the precision of gear precision can reach level 6, achieving seamless connection.

5. Equipment

Joiner is state-of-the art and spans over 20,000 square meters. The factory houses more than 140 sets of different domestic and foreign high precision production equipment, with the degree of numerical control up to 95%.
