Design and construction principle of screw of plastic extruder

Feeding area of plastic extruder: the groove depth of the screw groove of the fixed screw. Its function is to be responsible for preheating, plastic solid transportation and extrusion. It must be ensured that the plastic begins to melt at the end of the feed section - that is, preheat to the melting point. The general length is: amorphous (as, ABS, PS) about 48 ~ 58% L, crystalline (PA, POM, PE, PP, CA) about 48 ~ 58% L, and glass fiber added about 45 ~ 55% L.

Introduction to the production and application process of steel castings

Steel castings are widely used in people's lives. Steel castings are used in automobiles, high-speed railways and buildings in people's lives. Although steel castings have shortcomings, their advantages are also very obvious.

Methods of preventing cracks in steel castings

Cracks are divided into hot cracks and cold cracks. Hot cracks are mainly caused by S, mostly irregular shapes, and the metal skin at the cracks is oxidized; Cold cracks are mainly caused by P, the cracks are relatively straight, the cracks have metallic luster, and sometimes a slight oxidation color appears. Some steel castings use water blasting and sand cleaning process, which can also cause cracks.

Investment casting machining

Investment castings after casting process could only reach freedom tolerances itself.For more accurate tolerances,we have to meet by rough machining,some even require secondary machining.To serve our customers better,we have developed a machining line to machine parts we could not reach by investment casting.
