From Casting to Finished Parts

Many custom parts require more than casting alone. Based on your drawings and application requirements, we can combine investment casting, CNC machining, secondary processing and quality inspection to deliver parts closer to their final assembly condition.

01 Drawing Review

Review drawings, materials, tolerances and key functional requirements before production.

02 Investment Casting

Produce near-net-shape steel castings using the silica sol investment casting process.

03 CNC Machining

Machine critical faces, bores, threads, holes and other functional features as required.

04 Secondary Processing

Coordinate heat treatment, blasting, polishing or other specified downstream processes.

05 Quality Inspection

Check material, dimensions and critical features according to project requirements.

06 Finished Parts

Deliver completed parts prepared for your next assembly or production stage.
