Pattern
Patterniakking and toolmaking are at the core of the foundry process. While technology has
evolved with the introduction of 3D printing, the demand for exceptional quality remains
unchanged.
- Whether sourcing a 3D-printed pattern for rapid prototyping or a CNC-machined die for high-precision investment casting, we ensure that the quality of the tooling directly translates into the quality of the final casting—we never compromise on excellence.
Our Expertise in Tooling & Design
Our design engineering team and foundry experts work closely with customers to develop
tailored tooling solutions for every project. By considering:
- Component specifications
- Production processes
- Casting alloys
- Production volumes
We ensure that the tooling we provide consistently delivers high-quality castings throughout its service life.

At SEI, our commitment to precision and quality in patternmaking and toolmaking ensures that every casting meets the highest industry standards.
