We provide design for manufacturability support and offer free consultation to customers regarding material specifications and process selection to ensure optimal performance properties and overall cost effectiveness. With our robust process capabilities, we manufacture cast parts for leading OEMs in the medical industry.

Investment casting provides a high degree of design flexibility. Complex and multi-part components can be cast into one piece and net shape, reducing or eliminating the need for secondary machining. With our state-of-the-art foundry equipment and automation process controls, we achieve consistent and high quality of the products.

Inside our quality lab, our team of experienced engineers, chemists, and technicians leverage a wide range of non-destructive and laboratory test methods to ensure the integrity of the internal structure and the material composition. We handle orders for both high and low volumes. For more information about our investment casting capabilities or to request a quote, contact us now.
