What does metalworking mean?
Plastic molding processing includes:
Forging: Under the condition of cold working or high temperature operation, metal is shaped by beating and extrusion, which is one of the simplest and oldest metal modeling processes.
Matching: The high-temperature metal blank passes through several continuous cylindrical rollers, and the rollers insert the metal into the mold to obtain the predetermined shape.
Wire drawing: the process of drawing metal strips into filaments with a series of wire drawing dies with decreasing specifications.
Extrusion: a low-cost process of continuous processing. Solid or hollow metal is formed with the same cross-sectional shape, which can be used for both high-temperature operation and cold working.
Impact extrusion: a process used to process small and medium-sized parts without taper requirements. The production speed is fast, parts with various wall thicknesses can be processed, and the processing cost is low.
Powder metallurgy: a process that can process ferrous and non-ferrous metal parts. Comprises two basic processes of mixing alloy powder and pressing the mixture into a mold. Metal particles are formed by high temperature heating and sintering. This process does not need mechanical processing, the utilization rate of raw materials can reach 97%, and different parts of the mold can be filled with different metal powders.
Solid forming process
Solid forming processing: refers to the use of raw materials such as some metal bars, sheets and other solid forms that can be formed at room temperature. It belongs to labor-intensive production. The processing cost can be relatively low.
