Development of a Cold Rolled Steel Starburst Core Die for the Diesel Trucks Industry

( Click image to enlarge )

With more than 50 years’ experience, CLL Engineering is highly capable of innovating value solutions for unique manufacturing requirements. We fabricated this finely detailed starburst core die shown here for a customer in the diesel truck industry, it represents our ability to deliver a novel solution for a singular application.

Our precision step-by-step process began with a design review, followed by a 3D CAD rendering to validate the die design and simulate the manufacturing process. Fabricated from cold rolled steel, our master toolmakers utilized a variety of capabilities, including prototyping, machining, heat treating, finish grinding, and assembly, to complete the diemaking process. The finished die featured dimensions of 30" in length, 20" in width, all to tolerances of ±0.001". A die try-out, combined with a long list of inspection procedures, ensured that our customer’s end-product requirements would be met.

With careful consideration of tolerances, finishing requirements, and all other project parameters, we were able to deliver this starburst core die to the customer on time and within budgetary constraints.
