Micro Molding
As medical devices push the boundaries of anatomical access, miniaturization is essential across components and subassemblies. Traditional injection molding has long been a cornerstone of medical manufacturing, but as devices shrink, the need for precision micro molding has emerged.
At Nissha Medical Technologies, micro molding is a core capability, enabling the cost-effective production of highly intricate, ultra-small components with exceptional accuracy. Whether for complex geometries or critical dimensional precision, our expertise ensures that even the smallest parts meet the highest performance standards.

Advantages and Capabilities
Thin Wall and Long Aspect Ratio Parts
Precision micro molding allows for wall thicknesses as thin as 0.001" and aspect ratios up to 400:1. These parts are engineered for strength, flexibility, and performance in demanding medical and drug delivery applications.
Uses:
- Drug Delivery
Multi Shot Parts & Two Shot Molded Parts
Two-shot molding combines different materials or colors into one micro part for added functionality or simplified assembly. This technique is ideal for seals, gaskets, overmolded features, and geometries that are too complex or delicate for manual handling.
Uses:
- Minimally Invasive Surgical Devices
Parts for Optics
Micro injection molded components engineered for optical clarity and precision—ideal for guiding lasers, lenses, and light through highly sensitive medical and diagnostic devices.
Uses:
- IOL (Interocular Lens)
Parts with Slides/Undercuts
Micro molds use side actions, lifters, and collapsible cores to form undercuts, internal threads, and other trapped features that cannot be ejected straight. This enables complex geometry in one shot with reliable ejection and repeatable tolerances.
Uses:
- No specific uses, very common in all micro molded components
Extreme Small Parts
Micro molded parts can be as small as a dust speck and still meet tight tolerances for critical medical and drug delivery applications. These ultra-miniature components often enable the entire device’s performance and functionality.
Uses:
- No specific uses, very common in all micro molded components
Medical Device OEMs are constantly innovating to develop lifesaving / life changing devices and technologies. I believe that it is our duty as sub-micron precision tooling, molding, and automation experts to push the boundaries of injection molding and assembly to enable medical OEMs to achieve their miniaturization and cost reduction goals.
