Our core process for assisting clients from concept to mass production
Submit your samples or drawings for a manufacturability review by our engineers. Potential risks—such as warpage, sink marks, and ejection issues—are identified before tooling begins, with material recommendations provided as needed.
Where needed, SLA 3D-printed samples help clients verify appearance, assembly interference, and other design details before tooling—reducing the risk of design changes after mold fabrication begins.
Molds are fabricated using CNC milling and other precision machining equipment. Upon completion, a first trial shot (T1) is submitted for client review. Production begins once the samples are approved.
Once the mold is approved, production begins. The appropriate injection machine and process parameters are selected based on client requirements and part characteristics, ensuring product quality and on-time delivery.
