Top 15 Micro Molding Companies In the World


According to our statistics, there are millions of injection molding companies worldwide. Some plastic injection molding factories produce their own products, while others provide customized injection molding services. Among these plastic molding enterprises, micro-molding enterprises account for about 5%. The high threshold is the primary reason restricting their entry. There are both cost and technical reasons.

Today, we collected and organized well-known micro-molding manufacturers worldwide and described each company’s advantages in detail. If you are looking for a micro injection molding injection molder, these companies can provide a reference for you.

Micro Molding Overview

Micro molding is a specialized manufacturing process used to create small, highly detailed plastic parts. It is predicted that the size of the global microinjection molding market will reach US$1.58 billion by 2024. Some key aspects of micro molding include:


Micro molding uses precision molds and complex injection molding machines to form miniature plastic parts with feature sizes often less than 1 mm. Tight tolerances on the order of microns allow for creating intricate microscale detail.


Areas where micro molding is applied include electronics, medical devices, optics and more. It enables manufacturing small components for technologies like microfluidics, lab-on-a-chip devices, micro-optics and MEMS.


Specialty engineering thermoplastics like LCP, PEEK, Nylon, PMMA and PP are commonly used as they can achieve high resolutions. Epoxies and silicones are also suitable for certain micro molded parts.


Producing very small parts with fine detail poses challenges in areas like mold design/machining, precise process control and handling/assembling finished micro parts. Sophisticated equipment and production techniques are required
