Tooling to Manufacture Die Cast Parts: The design and manufacturing of Die Cast Tooling, Dies, or Molds is critical to the final quality of your die cast component parts. The type/ form of tooling best suited for your die cast parts will depend on the quantity, part design and size, and perhaps mating parts (family die/ mold). In addition to the die/ mold to cast your component parts, it may also increase quality and reduce part cost by utilizing a trim die.

Manufacturing New Die Cast Tooling: Shamrock Industries understands that tool design and manufacturing is critical to successful and timely production of aluminum and zinc die cast parts. Because Shamrock Industries services numerous industries with diverse part designs, we have found it beneficial to the customer for Shamrock Industries to obtain tooling quotations from our qualified tooling craftsmen located in the U.S. and present our recommendations to the customer. Commercial transactions for tooling are directly with the customer and the toolmakers. Shamrock Industries interfaces with both the client and toolmaker on design consideration and schedule of initial first article die cast parts. Typically, first article die cast parts are manufactured within a couple days of receiving the new die cast tool. Tooling manufactured in U.S. also helps control of your intellectual property and market introduction of new products.

Transferring of Die Cast Tooling: Shamrock Industries welcomes your existing die cast tools and molds. Shamrock Industries can accommodate insert dies and unit dies utilizing our mold bases, family mold tools, and full Class “A” die cast tooling. When your die cast tooling arrives at Shamrock Industries we will immediately inspect and photograph and advise you of status tooling. Any needed repair/ maintenance will be performed and first articles provided immediately for your review. There is no charge for running first articles on transferred tooling for aluminum and zinc die cast parts.

Maintenance of your tooling: Tooling maintenance and minor modifications are performed in-house. Shamrock Industries takes great care in maintaining your tooling to insure optimal quality of die cast parts and life of tools.

Aluminum and Zinc Die Cast Parts versus Plastic Injection Molded Parts

  • Die cast parts will have better mechanical strength than most plastics
  • Die cast parts are more resistant to heat and thermal cycling
  • With the same dimensions, die cast parts are stronger than plastics
  • Die cast parts can be thinner and lighter than plastic equivalent and still meet mechanical requirements
  • Thin-walled die castings can accommodate stresses where a comparable plastic parts cannot succeed
  • Die cast parts are more dimensionally because of the stiffness of the alloys versus plastics
  • Die cast alloys are inherently electrically conductive
  • Die cast alloys provide inherent shielding from EMI
  • Die cast alloys are 1,000 times more thermally conductive than plastics
  • Die cast alloys resist creep better than plastics
  • Die cast parts can hold closer tolerances than plastics because of stiffness and thermal stability
  • Die cast parts are ‘green’ --- over 95% of aluminum die cast parts produced in North America use recycled aluminum
  • Die cast parts can be plated for aesthetics
  • Die cast parts have high yield and impact strength
  • Die cast alloys are not affected by UV rays
