Why Altera

Four things that set us apart

01

Digital file to finished part

STEP, IGES, STL, OBJ — we handle mechanical and organic geometries with equal confidence. File decimation, format conversion, and DFM feedback included.

02

Common tool base systems

Standardized steel bases with interchangeable inserts. Your first mold pays for the base; subsequent variants only need new inserts — dramatically lower per-part costs across product families.

03

On-shore production model

Molds tooled by our partners in China, air-shipped as components, with final production and QC in Portland, Oregon. Global tooling economics, domestic quality assurance.

04

Product assessment

We evaluate existing designs and production methods to identify cost reduction and quality improvement opportunities before you commit to tooling. Cross-industry R&D insight applied to every project.

Strategic On-Shore Production

Molds are produced by our tooling partners in China — where decades of precision mold-making infrastructure deliver exceptional quality — then air-shipped as components to Portland for domestic production, QC, and fulfillment. You get globally competitive tooling costs with US-based quality control. No single-country dependency. No overseas quality risk.

Tooling: China & USA Production: Portland, OR QC: 100% domestic

"We sent them a PEEK manifold that three other shops said couldn't be done. They shipped finished parts in four days."
