Manufacturing of screws

Here is an example of the production of a screw for extruding a mixture.

Here is an introduction to a case study of screw production that we handled. A screw is generally a propulsion device used for waterborne movement of ships, but what we manufactured this time is a screw for extruding powder. By using the screw for extrusion, we can efficiently transport the powder while eliminating clumps. 【Production Overview】 ■ Step 1: Prepare the materials for the shaft and blades. ■ Step 2: Weld the ring with cuts together. ■ Step 3: Stretch it out. ■ Step 4: Set it onto the shaft. ■ Step 5: Adjust the spacing of the blades. ■ Step 6: After adjustment, secure it with welding.
