    Mold types and classification

    Mold types and classificationType of moldMany types of moldsAccording to the processing object and processing technology, it can be divided into:① Die for processing metal.② Process non-metallic and powder metallurgy molds. Including plastic molds (such as two-color molds, compression molds and extrusion molds, etc.), rubber molds and powder metallurgy molds. According to the structural characteristics, the die can be divided into a flat blanking die and a cavity die with space. Moulds are generally single-piece and produced in small batches.Mold classificationDepending on the material being formedMetal molds, plastic molds, and their special molds.Hardware dies are divided into: including stamping dies (such as punching dies, bending dies, deep drawing dies, turning dies, shrinkage dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies, upsetting dies, etc.) forging dies, etc.), extrusion dies, extrusion dies, die-casting dies, forging dies, etc.;Non-metallic molds are divided into: plastic molds, inorganic non-metallic molds, sand molds, vacuum molds and paraffin molds.Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds, etc.Suzhou Huihong Electric Co., Ltd. is a professional manufacturer of precision molds , injection molding, assembling and silk-printing. Some moulds are exported to Japan, Europe and the United States. We have the right to import and export the goods. We can develop and manufacture the moulds according to the needs of our customers. We pay attention to quality control, new project development, personnel training, team spirit. In recent years, we have established long-term business relationships with many well-known enterprises at home and abroad.

    What is a mold?

    What is a mold?Molds, various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In a nutshell, a mold is a tool used to make a shaped item, this tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. Known as the "Mother of Industry".Under the action of external force, the blank becomes a tool with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with the cutting edge can separate the blank according to the contour shape (blanking). Applying the cavity shape allows the blank to obtain a corresponding three-dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or a punch and a concave mold), which can be divided and combined. When separated, the parts are taken out, and when closed, the blanks are injected into the mold cavity to form. The mold is a precision tool with complex shape, which bears the expansion force of the blank, and has high requirements on structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of machinery manufacturing.Many types of moldsAccording to the processing object and processing technology, it can be divided into:① Die for processing metal.② Process non-metallic and powder metallurgy molds.
