Material
PMMA is a clear, glass-like plastic. We mold it into transparent, light parts.
Overview
PMMA is a clear, glass-like plastic. We mold it into transparent, light parts.
PMMA (Acrylic, also called Plexiglas) is a clear plastic. It looks like glass but is lighter and tougher, and molds into precise parts.
We melt plastic resin and inject it into a steel mold to form identical parts.
High-volume parts with consistent size and finish, made to your drawing.

How It Works
From your file to a finished part in five clear steps. Start with a free quote.
Upload your 3D file and drawings. Get a quote with free DFM feedback, usually within 24 hours.
Our engineers check wall thickness, draft, and gates. We suggest changes that cut cost.
We design and build the steel mold that shapes your part.
We melt the resin and inject it into the mold, then cool and eject the part.
We check dimensions and quality, then pack and ship worldwide.
Applications
Clear guards and displays.
Even, soft light.
Bright, clean panels.
Clear, neat housings.
Design Tips
New to this process? These simple rules help your part turn out well and cost less.
Use a steady wall thickness so the part fills evenly and warps less.
A small draft (1–2°) on vertical faces helps the part release from the mold.
Plastics shrink as they cool. We size the mold to land on your final dimensions.
Finishes
The natural molded surface straight from the tool. Lowest cost.
A custom color coat for branding or looks.
A matte or patterned surface for grip or style.
A glossy protective layer for a premium look.
