Plastic molds are an important tool for manufacturing plastic products, and there are many types of them, which can be divided into different types according to different classification standards. This article will introduce the main types of plastic molds and explain their characteristics.
1. Classification according to the shape of plastic products.
1.Extrusion molds.
Extrusion molds are mainly used for the production of plastic products such as pipes, sheets, and profiles. This kind of mold is usually composed of multiple parts, including the machine head, shaping mold, cooling system, etc. Extrusion molding molds have the characteristics of simple structure, high production efficiency and stable product size.
2.Injection molding molds.
Injection molding molds are mainly used to produce plastic products of various shapes, such as daily necessities, toys, medical equipment, etc. This kind of mold is usually composed of two parts: a moving mold and a fixed mold, and the molten plastic is injected into the mold through an injection molding machine, and the product of the desired shape is obtained after cooling. Injection molding molds have the characteristics of complex structure, high precision and wide range of application.
3.Blow molding molds.
Blow molding molds are mainly used to produce various hollow plastic products, such as beverage bottles, shampoo bottles, etc. This kind of mold is usually composed of a blown film head, a shaping mold, a cooling system, etc. The blow molding mold has the characteristics of simple structure, high production efficiency and light product weight.
2. Classification according to plastic products.
1.Polyethylene (PE) molds.
Polyethylene is a common plastic material with excellent corrosion, abrasion and impact resistance. Polyethylene molds are usually used to produce various daily necessities, pipes, sheets, etc. This kind of mold has the characteristics of simple structure, low cost and long service life.
2.Polypropylene (PP) molds.
Polypropylene is a lightweight, highly transparent plastic material with good impact and heat resistance. Polypropylene molds are commonly used in the production of various medical devices, food packaging, etc. This kind of mold has the characteristics of simple structure, low cost and long service life.
3.Polyvinyl chloride (PVC) molds.
Polyvinyl chloride is a plastic material with excellent corrosion resistance, flame retardancy and impact resistance. PVC molds are commonly used in the production of various building materials, wires and cables, etc. This kind of mold has the characteristics of complex structure, high cost and long service life.
4.Polycarbonate (PC) mold polycarbonate is a plastic material with high transparency and high strength, with good impact resistance and heat resistance. Polycarbonate molds are commonly used in the production of various optical instruments, medical devices, etc. This kind of mold has the characteristics of complex structure, high cost and long service life. 5.Polystyrene (PS) mold polystyrene is a lightweight, easy-to-process plastic material with good insulation and heat resistance. Polystyrene molds are usually used in the production of various daily necessities, toys, etc. This kind of mold has the characteristics of simple structure, low cost and short service life. 3. Classification according to the size of plastic products 1Large Size Plastic MoldsLarge size plastic molds are usually used to produce large plastic products, such as auto parts, building templates, etc. This kind of mold has the characteristics of complex structure, high precision and high cost. 2.Small Size Plastic MoldsSmall size plastic molds are usually used to produce small plastic products, such as electronic components, cosmetic packaging, etc. This kind of mold has the characteristics of simple structure, low cost and high production efficiency. Fourth, according to the use of plastic products classification 1Industrial Plastic MoldsIndustrial plastic molds are usually used to produce various industrial products, such as mechanical parts, pipes, etc. This kind of mold has the characteristics of complex structure, high precision and corrosion resistance. 2.Medical Plastic MoldsMedical plastic molds are commonly used in the production of medical devices and supplies, such as syringes, infusion sets, etc. This kind of mold has the characteristics of non-toxic and harmless, environmental protection and hygiene, and meets the relevant standards of medical devices.
