Common Plastics for Injection Molding

Prototype and plastic mold is the abbreviation of a combination mold for compression, extrusion, injection, blow molding and low foam molding. The coordinated changes of mold convex and concave molds and auxiliary molding systems can process a series of plastic parts of different shapes and sizes.

Prototype Plastic Molding Commonly Used Materials
P20 steel is a low alloy steel with a wide range of uses. It is the most commonly used mold material in the plastic molding and manufacturing industry. Its main characteristics are as follows. High hardness, good polishing ability, heat treatment after processing, good corrosion resistance, good wear resistance and tear resistance.

S136 plastic mold steel has excellent corrosion resistance, wear resistance, polishability, machinability and dimensional stability, and can be widely used in cameras, sunglass lenses, syringes, analytical bottles, food industry mechanical components, etc.

NAK80 is a pre-hardened plastic mold steel with excellent polishability, machinability, etchability, sculptability, and electrical discharge machinability. The steel is pure with vacuum degassing and refining treatment, and no heat treatment is required. Therefore it can be widely used in mirror polishing molds, anti-dust, TV filter plates, cosmetic cases, precision wrinkle processing molds.

What are The Uses of Plastic Mold?

A mold is a tool used to make molded objects. This tool consists of various parts, and different molds consist of different parts. It is mainly used to process the shape of an article by changing the physical state of the material being molded. It is a tool to make a blank into a manufactured part with a specific shape and size under the action of external force. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and forming processing of engineering plastics, rubber, ceramics and other products of compression molding or injection molding. In products such as electronics, automobiles, motors, instruments, appliances, meters, home appliances and communications, 60%-80% of the parts rely on mold molding. The high precision, high complexity, high consistency, high productivity and low consumption of parts produced by molds are incomparable to other processing and manufacturing methods. Mold and is the "benefit amplifier", the value of the final product produced by the mold, often dozens of times the value of the mold itself, hundreds of times.
