What is the plastic molding of metal products?

Plastic molding processing: refers to the high temperature of heating and molding metal for molding, which is labor-intensive production.

Classification of plastic molding and processing of metal products:

Forging: It is one of the simple and ancient metal molding processes.

The hot metal blank section passes through a plurality of continuous cylindrical rollers, and the metal is embedded in the mold to obtain the basic shape.

Wire: The process of creating a silk shape that grips a metal strip using a series of silk dies of progressively smaller gauges.

Extrusion: is a low-cost process for continuous processing, with the same cross-sectional shape, solid or hollow metal shape, and can be processed at high temperature and cold at the same time.

Impact extrusion: used to process small to medium-sized parts without chimney taper requirements. Fast production and can process parts with various wall thicknesses. Low processing cost.

Powder metallurgy: It is a process that can process both ferrous metal parts and non-ferrous metal parts. There are two basic procedures including mixing the alloy powder and placing the mixture into the mold. The metal particles are formed by high temperature heating and sintering. This process does not require machining, and the utilization rate of raw materials can reach 97%. Different parts of the mold can be filled with different metal powders.

How are metal products formed in solid form?

Solid forming processing: refers to the use of metal strips, chips and other solid forms that can be formed from raw materials at room temperature. It is labor-intensive production. The processing cost input may be cheaper.

Solid molding processing classification:

Rotation: It is a very common processing method for producing circular symmetrical parts (such as plates, cups, cones, etc.). During processing, a metal plate rotating at high speed is pushed onto a model of a fixed bed that is also rotating to obtain a predetermined shape. The process is suitable for production in various batch formats.

Bending: is an economical production process for processing certain forms of sheet, rod and tubular materials.

Continuous binding type: The metal sheet is fed between the rollers to obtain a metal shape with continuous length and uniform cross-section. Similar to the extrusion process, but there are restrictions on the wall thickness of the machined element, so only a single wall thickness can be obtained. The processing cost is reasonable only under the premise of mass production.

How are metal products stamped?

A sheet of metal is placed between the positive and negative shapes for the processing of hollow shapes by compression molding, which may be shallower in depth.

Stamping: The process of cutting a specific shape can be all applied to sheet metal in large and small batches using special tools.

Punching: Basically similar to the stamping process, except that the former uses a punched part, while the latter uses the rest of the sheet metal after punching.

Cut: Cutting a metal piece is like cutting paper with scissors in place.

Cutting debris forming: When metal, the cutting methods with debris production are collectively referred to as milling, drilling, lathe processing and wear, sawing and other processes. Non-Chip Molding: Modeling using existing metal strips or sheets, etc. No crumbs were produced. These processes include chemical machining, etching, electrical discharge machining, sandblasting, laser cutting, spray cutting, thermal cutting, and more.
