Dynacast
While Dynacast specializes in high volume die casting, many of our projects generate less than $50,000 a year in revenue.
Dynacast specializes in small, precision components. We can cast parts up to the size of a laptop computer depending on the weight of the component but parts that fit in the palm of your hand and even tip of your finger are our niche.
The 3 CAD files are helpful, but most do not include tolerances or additional notes that may apply to the part, which is why the 2D drawings are needed.
To expedite your request for a quote, please include:
- Component application or function
- Alloy/Material
- Annual production quantity
- Approximate size of component
- Approximate life of program
- Where the program ship to location is
- 3D CAD and 2D files
To expedite your request for a quote, we suggest signing our NDA form. We can use your form if that is necessary, just know that it may slow the RFQ process.
Yes, Dynacast does guarantee the life of our dies depending on the material used. For specific information on our guarantees, contact our engineering team.
Dynacast multi-slide tools are only available for hot chamber die casting alloys.
Yes, Dynacast can utilize dies from other casting companies; however, we have to evaluate the quality of the tool before putting it into production to ensure the best quality parts.
Most designers are surprised to learn the best time to connect with our engineers is early on in product design. Our expertise in design for manufacturing can help to determine the best material and design for your part to be successful during mass production.
Dynacast offers zinc, aluminum, and magnesium die cast alloys.
Die Casting
The minimum or maximum cross-sectional wall thickness on any part is very much dependent on the overall part size and design. As an example, a 0.010” wall thickness may be possible if it’s localized but is not possible if it is across the entire length of the 4” long part. Generally, the optimum wall thickness is 0.040” to 0.120” and again, is related to the overall size of the part. Minimizing wall thickness also reduces the material content of a part and its cost.
Yes, Dynacast tries to recycle as much scrap metal as possible. Aluminum is the best and easiest metal to recycle.
No, the exact alloys are not appropriate for each process. Your design engineer can help you find an alloy that is similar. It will not be the exact same alloy, but it will have very similar physical properties.
No, porosity is inherent to the die casting process. However, with proper tool design, porosity can be minimized and localized in noncritical areas.
You can view all of the surface finishes we offer, here.
The density of a die casting alloy in the molten state is less than its density in the solid state. Therefore, when an alloy changes phase from the molten state to the solid state, it always shrinks in size—causing solidification or shrinkage porosity. Entrapped air or gas porosity is caused by poor shot end control, poor venting or overflow function, or a bad gating and runner design.
Yes, zinc, aluminum, and magnesium are all used in EMI-RMF shielding applications.
Yes, it is necessary. The appearance, adhesion, and acceptance of the finished article depend primarily on a sound foundation for the final finish, which is achieved only with an active and clean substrate. To ensure quality parts, a properly designed pre-plating process is a must.
Almost all of the surface finishes that we have are appropriate for aluminum die casting, including all plating, painting, e-coating, anodizing, and chem film.
Yes, we can anodize die cast aluminum. For larger parts, it’s a functional coating that acts as a base coat for painting or provides additional corrosion resistance. For smaller parts that ‘fit in the palm of your hand’, it can be cosmetic with proper tool design and production processes.
B390 has the highest thermal conductivity (143 W/m K) it is an aluminum alloy with high hardness and good wear resistance.
No, you cannot weld a die cast part. It destroys the casting and due to the nature of the alloy content no weld would occur. You can, however, solder a zinc die cast part that has ben tin-plated. This is typically done on electronic components.
