Deco Products Questions
Do you offer prototyping services?
- When it comes to prototype zinc die castings, there is no perfect solution currently. Prototyping methods can include rapid tooling, machined parts, investment casting, spin casting, sand casting, and 3D printing, all of which has some advantages and disadvantages. To learn more about each of these prototyping methods, check out our Prototyping Zinc Die Castings page. Or contact a Deco Product expert to help you navigate these options for prototyping and further support during the design verification/validation processes.
How large of a die casting can DECO produce?
- Deco products can produce parts from as small as a few ounces to as large as 8 lbs.
Can Deco accept and utilize dies transferred from other die casters if they have not been designed to run on Deco machines?
- Deco Products has decades of experience in tooling transfers. Our expert engineers will work with you to ensure it fits onto one of our 88 zinc die cast machines. If needed, we can modify the tool in our tool room, and sample the part without interruption of ongoing production.
When is the best time to contact Deco for a quote?
- The best time to contact Deco for a quote is early in the part design process. By incorporating our engineering team early in the design process, Deco can help ensure the die cast parts are going to be manufactural and ready for your testing and/or production needs.
What materials does Deco offer?
- Deco does all die casting with zinc specifically. The zinc alloy types we use at Deco are ZAMAK #3, ZAMAK #5, ZAMAK #7, ZAMAK #2, ZA-8, and EZAC. (MATERIALS PAGE)
Die Casting Questions
What is the typical minimum wall thickness of zinc die castings?
- Typically, our engineering team aims for 1/10th of an inch over long areas, but for specific features parts can be cast thinner. Although this is typical, all parts and designs are unique. Our expert engineering team anticipates working with customer’s design idea regardless of desired thicknesses and thinness.
Can Deco recycle gates and runners?
- Yes, Deco recycles scrap zinc left over from the die casting process. This scrap gets melted down and molded back into parts. Unlike plastic, zinc material properties do not degrade when being re-melted.
Can I expect to receive die cast parts that are 100% free of porosity defects?
- All die cast parts will have some level of porosity. The trick is to minimize the size and amount of porosity. Deco uses mold-flow software to help minimize part porosity.
What die cast alloy has the highest thermal conductivity?
- Measured (BTU/ft/hr/degrees F), the zinc alloy thermal conductivity for the alloys used at Deco are: (Zamak #3: 65.3) (Zamak #5: 62.9) (Zamak #7: 65.3) (Zamak #2: 60.2) (EZAC: 60-67) (ZA-8: 66.3) For more information look at our materials page.
Can you weld die cast parts?
- Die cast parts are not easily soldered or welded together. However, a property of zinc die casting is its ability to be molded or cast into the desired shape. Thus, it is possible to take a design of multiple parts into a design with a single casting. Our exceptional engineering team can assist in your project to make sure Deco is providing you with the best option.
Powder Coating and Plating Questions
What powder coating finishes does Deco offer?
- Deco offers over 100 different powder coating finishes with the ability to process special colors. Contact our sales team to request a color chip sample.
Is it necessary to wash or shot blast die castings prior to applications of any plating or coating?
- Deco washes and dries all parts during the zinc die casting process to ensure that parts are smooth and free of imperfections that will impact the appearance of the finished part.
- It is a standard rule of thumb to clean any part prior to applying a finish. It is the same for zinc die castings. However, it is not required to shot blast a zinc die casting prior to plating.
