Plastic injection molds are ideal for producing high volumes of plastic parts, due to the ability of making multi-cavity injection molded parts, where multiple parts are made with one cycle. Some advantages of injection molding are high tolerances, repeatability, a wide range of material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding.
- Injection Molding Machine
Injection Molding Machine, also known as presses, consist of a material hopper, an injection ram or screw-type plunger, and a heating unit. Molds are clamped to the platen of the molding machine, where plastic is injected into the mold through the sprue orifice.
Mold or Die are the common terms used to describe the tooling to produce injection plastic parts. Molds are typically constructed from hardened steel, pre-hardened steel, aluminum, and/or beryllium-copper alloy. The choice of material to build a mold from is primarily one of economics.
Modern hard aluminum with proper mold design can easily make molds capable of 100,000 or more part life with proper mold maintenance.
Two main methods: standard machining and EDM. Standard machining has been the method of building injection molds. CNC machining became the predominant means of making more complex molds with more accurate mold details in less time than traditional methods. The electrical discharge machining (EDM) has become widely used in mold making. As well as allowing the formation of shapes that are difficult to machine, the process allows pre-hardened molds to be shaped so that no heat treatment is required.
Gestion de Compras supplies plastic injection molds for household appliances sector (trays and front refrigerators, washing machine parts...), automotive (bumpers, grille, fans, control panel...), packages(boxes horticultural, beverage boxes, storage boxes...) packaging (thin wall IML, glasses, caps, PET preforms), and air conditioning (indoor machine housings, vents...). And molds with drawings specifications can be supplied also.
