Micro Molding Services
Liquitac offers the highest quality micro molding services and can assist in the production of parts with intricate and complex geometries and excellent surface finishes. Subject to availability.Â
Micro molding is a highly advanced and specialized manufacturing process that enables the fabrication of complex, miniature parts with incredible precision. Considered a subset of plastic injection molding, micro molding is tailored for producing parts with features typically less than one millimeter. It has gained prominence in industries like: medical device manufacturing, electronics, automotive, and aerospace. The ability to efficiently create precise parts with minute features in large volumes and in a wide range of compatible materials are some of the biggest advantages of custom plastic injection micro molding.
Liquitac offers high-quality micro molding services for a variety of industries and applications. Common applications for micro injection molding include integrated circuit components and automotive door-locking mechanisms. Our vast manufacturing network coupled with our extensive manufacturing experience ensures your parts will be made to the highest standards of quality with short lead times.
The Micro Injection Molding Process
The micro molding process is nearly identical to the standard plastic injection molding process but requires more careful control to ensure high-quality parts. Before micro injection molding can actually begin, molds and die sets must be fabricated. Precise and advanced manufacturing methods such as electric discharge machining (EDM), micro EDM, and micro-machining are used to create extremely precise molds with tolerances as small as a few micrometers. Once fabricated, molds can be mounted in a micro injection machine. Then, a thermoplastic or liquid silicone rubber is melted and maintained at a consistent temperature. The molten material is forced into the micro mold with a controlled flow rate and held at a particular pressure while it cools. Advanced programming and controls within micro injection molding machines ensure molding parameters are stable and consistent. Once sufficiently cooled, the micro injection molded parts are ejected from the mold and inspected to ensure dimensional tolerances are met.
Types of Micro Molding Processes
There are various types of micro molding, each with its own sets of advantages and disadvantages and special use cases. The different types of micro molding processes are listed and described below:
- Insert Molding
- Overmolding
