Micro Injection Molding: Principle, Benefits, and Applications – MING LI

What Is Micro Injection Molding

Micro injection molding is a specialized manufacturing process that produces small and accurate parts in large quantities. It is often used in the production of intricate and delicate items that require high precision and quality. Despite its small size, micro injection molding involves a complex set of processes and techniques that require specialized machinery and skilled operators.

At MING-LI, we are proud to be a leading manufacturer of micro injection molding solutions in Taiwan. Our state-of-the-art facilities and experienced team enable us to deliver high-quality and efficient micromolding services to clients from a wide range of industries, including healthcare, electronics, and automotive.

The basic of Micro Injection Molding

To understand the fundamentals of micro injection molding, it is important to first understand the basics of injection molding. Injection molding is the process of injecting molten plastic material into a mold cavity to create a specific shape or design. The process involves several steps, including melting and pressurizing the plastic material, injecting the molten material into the mold cavity, and cooling the material to form a solid part.

Micro injection molding is a variation of this process that is specifically designed to produce small, intricate, and precise parts. The process involves the use of high-precision molds, specialized machinery, and advanced control systems to produce parts that are often just a few millimeters in size.

The benefits of Micro Injection Molding

One of the key advantages of micro injection molding is its ability to produce complex geometries and designs that are difficult or impossible to achieve with other manufacturing processes. This is because the process enables the production of extremely small features, such as thin walls, sharp angles, and small cavities.

Another advantage of micro injection molding is its ability to produce parts with high dimensional accuracy and repeatability. This is because the process enables tight control over the molding parameters, such as temperature, pressure, and flow rate, ensuring that each part is produced to the exact same specifications.

To achieve these high levels of precision and quality, micro injection molding requires specialized machinery and tooling. This includes the use of high-precision molds that are specially designed for micro molding, as well as advanced control systems that enable tight control over the molding parameters.
