POM gears
Where POM can fit quiet, wear-resistant injection-molded gear applications.
CNC or injection
How quantity, geometry, and tooling change the right production route.
Mold decisions
What to define before paying for tooling and approving production samples.
Tooling Ownership: What to Lock In Before You Pay
Injection molds outlive any production run. Decide who pays, who owns, and who can move the tool before the first tooling invoice — in writing.
What to Send When You Start a Manufacturing Project
A sample, CAD file, or clear photos are usually enough for a useful first review. Here is what helps an engineer answer faster — and what you do not need yet.
Why POM Fits Quiet, Wear-Resistant Gears
POM is not the only gear material, but its friction, stability, and wear behavior often make it a strong starting point for precision plastic gears.
Designing for Manufacturing: 5 Decisions Upfront
Material selection comes last, not first. Decide function, environment, volume, tolerance, and budget before asking what a part should be made of.
CNC vs Injection Molding: Which Fits Your Part
The two most common processes for custom parts are not interchangeable. Here's how to decide which one fits your project.
