Injection molding is a production procedure for making pieces by pouring molten plastic material into a mould, usually made from metal, plastic or any other material usually made of hardened thermo-plastic. Injection molding is usually done with a host of different materials mostly comprising metals, plastics, glasses, thermoplastics, and most recently thermoplastic and polymers. The most common materials used in injection molding are polyethylene (PE), polypropylene (PP) and thermoplastic. Other materials that can also be used in the production of parts are polyester, fiberglass, nylon, polystyrene and others.
One of the most common uses of a Lego Injection Mould is when a person needs to produce large numbers of small parts that require frequent replacement of particular parts due to breakage or wear. Plastic Lego parts can be easily moulded into different sizes according to the requirement of the manufacturer or the customer. They can also be produced at a low cost, as the plastic parts and accessories produced by this process are generally very low priced. By using Lego Injection Moulds, an individual can also make very intricate detailed pieces.
A Lego Injection Mould is made up of two major parts - the motor and the pallet. The motor includes all the electrical components required to drive the machine during the whole injection moulding cycle. The pallet on the other hand contains the material that is to be injected into the plastic part during the whole cycle. The speed at which the motor spins affects how quickly the plastic part fits into the mould, thus controlling the diameter and thickness of the polymer filament needed to manufacture the Lego piece.
