Precision plastic molds are at the heart of industries like medical devices, automotive sensors, optical lenses, and connectors, where even the slightest deviation can impact performance or safety.

At MID Mold, we specialize in precision mold manufacturing using the following materials:

Key Capabilities

Using high-grade steels such as S136, H13, 1.2343, and 1.2344
Advanced machining equipment: Swiss EDM machines (AgieCharmilles), Japanese CNC machines (Mazak, FANUC), and high-speed engraving machines
In-house quality control tools: Coordinate Measuring Machines (CMMs), projectors, height gauges, and 2.5D viewing scopes

Mold Features

The molds we routinely manufacture feature the following:

Extremely tight tolerances, down to ±0.005 mm
Polishing to SPI A1/optical grade
Precision injection molding of metal parts with precise alignment
Microstructured surface patterning or engraving

Common Applications

These precision molds are commonly used in:

Medical: Syringe barrels, test cards, implant housings
Optical devices: Lenses, light guides, LEDs Reflectors
Electronics: Plug housings, micro connectors, switch components
Automotive: Sensor housings, gearboxes

Our Process

Each mold undergoes:

DFM analysis and tolerance studies
Moldflow simulation where necessary
Material and shrinkage compensation
Steel certification and dimensional verification

Our dedication to detail ensures every molded part meets our customers' critical specifications—from first piece to final batch.
