Getting a handle on die casting mold can be difficult

Getting a handle on die casting mold can be difficult. For this reason, the experts at Pace Industries are available to assist you throughout the entire process. A good example of how Pace is constantly working to provide customers with uncommon solutions would be the extensive product design assistance we provide.

On the design of our customers' castings, we collaborate with them to incorporate functional features that will keep the casting functional while also optimizing features that will make the casting more straightforward to manufacture. Consequently, we are able to provide our customers with a casting from Pace that is designed to reduce their costs while also allowing Pace to reduce our production costs.

Customers frequently know exactly what they want in terms of functionality, and we are experienced in producing castings that meet those requirements. Here are our top five tips to help you better understand our design process and the reasoning behind the design guidance we provide. 1. Know your audience.

TIP #1: Ensure that the wall thickness of the casting is consistent throughout the entire cast. Try to keep the variations in wall thickness to a bare minimum, even if this is not always possible.
In order to improve casting quality, this helps to improve metal flow and filling the mold cavity. It also helps to reduce dimensional variation caused by differences in cooling rates between the casting walls of different sizes.

IMPORTANT #2: The casting's corner radii (outside corners) and fillet radii (inside corners) should be the largest they can be.
In addition to increasing die life due to a reduction in the degradation of the die steel in sharp corner areas, this improves casting filling for improved quality and increases die life for improved quality.

3rd tip: When designing the casting, consider the draft (tapered walls). On the inside walls of the casting, you should have more taper (draft) than you do on the outside walls of the casting.
In order to remove the casting from the die, it is necessary to draft it out first.(This is the same reasoning that was used in the design of muffin tins, which have tapered walls to make it easier to remove the muffins from the tins. Due to the fact that the casting alloy shrinks as it solidifies, there is more draft on the interior walls. Molds are becoming smaller and more tightly fitted to the inside of the mold as time passes. Because of the increased draft, it is easier to remove the casting from the mold.

Tip #4: Keep critical dimensions on the same side of the die as possible. • Due to the fact that the die has moving components, dimensions that are based on features in multiple die components will have greater variation than dimensions based on features in a single die component.
When there is more variation in dimensions, tighter tolerances are required. These tolerances may not be acceptable in terms of the casting's functionality. Whenever this occurs, additional operations on the casting are required in order to maintain tolerances, resulting in increased costs to the client.(This is something we try to avoid at all costs!

Undercut geometry cannot be cast in a standard die cast die, so avoid them if at all possible. TIP #5:
Adding a sliding die member (also known as a "slide") to this undercut is necessary in order to cast this piece of casting geometry correctly. It is more expensive to cast a die with a "slide" added. The geometry of the undercut also has an impact on the amount of time required to complete the casting, which increases the cost to the client.

When you need help, we at Pace are here to help you out. It is our goal to assist you in understanding the design process and determining what will be the best fit for your casting requirements in the end. Also available at customer locations are casting design seminars where we meet with product design engineers in an informal, educational setting to provide a better understanding of what designs work best for precision die casting suppliers.

Our top priority is to provide our customers with high-quality products at competitive prices at all times, no matter what the situation. We can assist our customers in developing casting designs that meet their functional and castability requirements by working together on the development of the casting designs.
