What is Micro Molding?
Micro molding is a highly specialized injection molding process engineered for the fabrication of miniature, complex components with micron-level precision. As a sophisticated subset of traditional molding, it is specifically tailored to produce components weighing less than 1g and measuring within a few millimeters, enabling the consistent achievement of tight tolerances of ±0.001mm or better.
By leveraging micromolding machinery and high-performance resins like PEEK and LCP, this process enables the mass production of intricate geometries—such as 0.3mm thin-wall sections and complex micro-holes—while maintaining incredible consistency. Our in-house micro-tooling design (CNC/EDM) ensures that even the most ambitious designs are bridgeable to large-volume manufacturing. From microfluidic devices and mini-connectors to integrated circuit components, XY-GLOBAL delivers cost-effective excellence across the Medical, Electronics sector, and beyond.

Micro Molding FAQs
1. What is micro molding?
Micro molding creates tiny plastic parts, typically under 1mm, for medical devices, electronics, and microfluidics using specialized injection processes.
2. What sizes and tolerances can you achieve?
Minimum part sizes range 0.3–20mm, walls 0.15–0.3mm, holes 0.1mm+; tolerances ±0.01–0.02mm standard, ±3µm on critical features via SPC.
3. Which materials do you support?
PEEK, LCP, PPS, PC, PA, PEI, and 20+ high-flow thermoplastics; LSR for seals—all optimized for thin walls and <1cm³ shots.
4. What are your typical lead times for micro molding?
For most projects, prototype molds take about 3 days, and initial sample parts are usually ready in a week. Production then scales up seamlessly from those approved samples.
5. Do you have a minimum order quantity (MOQ)?
There is no MOQ for trial or prototype runs, so you can start with small quantities to validate your design before committing to full production.
6. When does micro molding become more cost-effective than CNC machining?
For complex geometries, high-volume runs of around 5,000 pieces or more can reduce per-part costs by over 50% compared with CNC machining.
