Isometric Micro Molding Technologies for Medical Devices, Optics, Microfluidics, and less invasive parts

Isometric Micro Molding

The largest medical-focused micro molder in the US

As medical devices push the limits of anatomical access and minimally invasive techniques, miniaturization across components and subassemblies is more critical than ever. Traditional molding methods often fall short when dimensional accuracy, complex geometries, and ultra-small features are required.

When it comes to micro molding, especially for high-precision markets such as medical and drug delivery devices, it’s critical to choose a partner with industry experience. With 35 years of experience and over 1,000 completed projects, Nissha Medical Technologies delivers precision-molded components that meet tight micron-level tolerances, including thin walls, micro holes, and high-aspect-ratio features.

Our vertically integrated approach allows us to design, tool, mold, and assemble complete micro solutions in-house, ensuring greater speed, reliability, and performance for every project. Nissha Medical Technologies provides complete end-to-end solutions for high-precision component design and micro mold manufacturing for micro-sized parts to larger parts with micro features, thin walls, complex geometries, micro holes, and/or tight tolerances.

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.
