Packaging Mould Manufacturers introduces the characteristics of 6 common plastic molds:
1. Injection mold:
It is mainly a molding mold that is widely used in the production of thermosetting plastic products. The production equipment that matches the injection molding mold is an injection molding machine. Injection molding production and processing methods are generally only suitable for the production and manufacture of thermoplastic products. Plastic products manufactured by injection molding processing techniques are very common, ranging from daily appliances to various complicated household appliances and auto parts. Molded by injection molding, it is a widely used production and processing method in the production of plastic products.
2. Injection mold:
A mold is used to mold hollow products such as plastic products. According to the basic principles of the processing technology, the injection molding methods include extrusion injection molding, hollow molding, and injection molding. According to the basic principles of processing technology, the specific methods include extrusion injection molding, hollow molding, and injection molding. Hollow molding, injection broadening injection hollow molding (alias injection stretch blow), double-layer injection hollow molding, plastic sheet injection hollow molding, etc. The corresponding facilities for injection molding of hollow products are generally called plastic injection molding machines, and injection molding is only suitable for the production of thermoplastic products.
3. Extrusion die:
A type of mold used for molding and manufacturing continuous injection products, also known as extrusion molding engines, is commonly used for the production and processing of pipe fittings, bars, wire drawing, plates, plastic films, cable and wire coatings, and PVC profiles. . Rather than say that the corresponding production equipment is a plastic granulator, its basic principle is that the solid plastic is melted and melted under the condition of heating and the screw of the plastic extruder rotating and filling, and the cross-section and Continuous plastic products with the same die-like shape.
4. Shock absorption mold:
A mold that uses plastic plates and plastic plates as raw materials to form some simpler plastic products. The basic principle is to use vacuum packaging or air compression molding to make the plastic plates and sheets fixed on the cavity or mold base. Under the condition of heating and dissolving, it is deformed and pasted on the concave mold of the mold to obtain the desired molded product. The key is to use the production and manufacturing level of some daily utensils, food, and small toy plastic packaging products.
5. Injection molding machine mold:
Contains two types of structural molds: shrink molding and injection molding. The key is a type of mold used to mold polyurethane elastomers. The corresponding facility is a working pressure molding machine. The key of the injection molding machine is a concave mold, a feeding cavity, a guiding organization, a release component, and a heating system. Bet molds are commonly used to encapsulate electrical components. The common materials used in the production of injection molding machine molds are basically the same as the injection molds.
6. High polyurethane foamed polyethylene molding mold:
A mold that uses expandable polyethylene raw materials to form various desired shapes of plastic foam packaging products. The basic principle is that the polyethylene can be steam-formed in the mold, including two types of simple manual actual operation molds and four-column hydraulic direct-connected plastic foam molds. The key is to produce packaging design at the level of manufacturing industrial supplies.
