It’s all about how you build the tool to build the part.’ ~ Alan Lipman, CEO Romar
Precision molding is the process of molding either silicone or plastic in a particular way, with a very high degree of accuracy and tolerance, to ensure repeatability in long machine runs.
What is metal casting?
Metal casting is the process of making objects by pouring molten metal into an empty shaped space. The metal then cools and hardens into the form given to it by this shaped mold. Casting is often a less expensive way to manufacture a piece compared with machining the part out of a piece of solid metal. There are many metal casting methods to choose from. What type of casting is most efficient depends on the metals used, the size of the run, and the complexity of the casting.
Before starting a production run, it is helpful to know some of the terms and methods from the foundry floor.
What is injection moulding? – definition, types and materials
Injection moulding is a manufacturing process that allows for parts to be produced in large volumes. It works by injecting molten materials into a mould (or ‘mold’ in the United States). It is typically used as a mass production process to manufacture thousands of identical items. Injection moulding materials include metals, glasses, elastomers and confections, although it is most commonly used with thermoplastic and thermosetting polymers.
How does it Work?
The first stage of injection moulding is to create the mould itself. Most moulds are made from metal, usually aluminium or steel, and precision machined to match the features of the product they are to produce.
When is Injection Moulding Used?
Injection moulding is used to make a range of widely used products, including common plastic items like bottle tops as well as remote control casings, syringes and more. It is also commonly used for manufacturing larger items such as car body panels.
Injection moulding is mainly used where there is a need to manufacture many thousands or millions of identical parts from a mould.
