What is micro moulding?

Micro moulding is a distinct kind of tight tolerance injection moulding method that necessitates precision and skill. It is a process where aluminium moulds or micro-structured steel are Computer Numerical Control (CNC) machined to a submicron or even a micron resolution. This product is small and light and used in specialised industries and crucial applications. Finished components can easily weigh less than 1 g and have cross-sectional dimensions less than 1 mm. A precise technique is designed for the mouldable material to achieve its melting point and then transfer it to the micro-moulding chamber to produce a micro-component. It creates a mould with a cavity specifying the shape of the component and injects mouldable material into the cavity. The required part is produced once the material is set. Because micro moulding machines offer higher resolution choices, they can inject a gram's fraction with excellent precision, resulting in equal pressure distribution. While micro moulding is about filling, CNC machining is a subtractive process that uses cutting tools and high-speed rotation to produce custom-designed parts or components by progressively removing material until the desired shape for the part is achieved. The CNC relies on digital instructions, often created using Computer-Aided Manufacturing (CAM) or Computer-Aided Design (CAD) software. The computer converts these files into a series of commands, which are then supplied to one or more milling tools, which work on the material to create the final product. It enables a quick transition between digital designs and physical parts.
