Your Full-Service Custom Parts Manufacturer

Topmetry offers fast, high-quality prototyping and production — from single parts to large volumes — thanks to our own factory and trusted partners.

CNC Machining

High-precision CNC milling and turning for prototypes and production parts — tight tolerances (±0.001″) and fast lead time.

Sheet Metal Fabrication

In-house die stamping with tooling expertise, combined with laser cutting, bending, and welding — delivering custom sheet metal parts with speed and precision.

Plastic Injection Molding

Custom plastic injection molding for prototypes and production — fast lead times, low tooling costs, and broad material options.

Wire EDM

Burr-free wire EDM for sharp internal corners, tight tolerances, and complex geometries — ideal for high-precision parts without tooling.

Surface Finishing

Access a full spectrum of surface finishing services — anodizing, plating, powder coating, polishing, and more — to make your parts durable, functional, and visually striking.

Assembly

Streamlined assembly services to simplify your supply chain — from basic mechanical subassemblies to ready-to-use components.

Built to
Manufacture

Faster, Easier, and Affordably

Back in 2010, Topmetry was founded with a clear goal: to make custom manufacturing faster, easier, and more dependable. It started with one engineer helping customers solve real production challenges.

Since then, we have grown into a trusted manufacturing partner for businesses in over 50 countries. With our own factory and a carefully vetted manufacturing network in China, we deliver precision parts quickly and cost-effectively — without compromising quality.

Whether you are prototyping or scaling up, we are here to help you build with confidence.

Quality You Can Count On

From First Cut to Final Check

At Topmetry, quality isn’t just a box to check — it’s built into every step of your project. From prototype to production, we follow strict standards to make sure every part meets your expectations for precision, consistency, and reliability.

Our experienced quality team uses calibrated tools and equipment — including CMM, micrometer, caliper, gauge, and XRF analyzer — to inspect dimensions, materials, and finishes. We conduct in-process checks as well as final inspections to deliver flawless parts — right the first time, every time.

Whether you need basic visual checks or detailed inspection reports like FAI (First Article Inspection), RoHS, or material certificates, we’ve got you covered. With an ISO 9001:2015-certified system and a commitment to continuous improvement, we help you manufacture with confidence — every time.
