At Household Appliance Enterprise, we are frequently asked for suggestions on how to improve the design of a component. I wanted to share with you some of the more common design tips that we recommend for die casting, and I thought you might find them useful. die casting can be carried out in a variety of metals, and the parts that are produced are extremely diverse. These suggestions, which are listed below, can assist with the design of a variety of parts. Always consider the alloy you intend to use as well as any surface finishing that you would like to have done after the part has been cast before making your decision.
Die Casting Variables are those that affect the way a die is cast.
a first draft
The first tip that I'd like to share is about adding draft to a part that has already been created. A slight taper is applied to the internal and external walls of a part, normal to the parting line, which is referred to as "adding draft."This helps to mitigate the effects of shrinkage and makes it easier to remove the casting from the cavity. Adding draft to a part makes it easier to cast the component. According to the alloy and process choices, recommended draft angles are typically in the range of 14 degrees to one degree per side. Ensure that your technical representative is aware of any critical areas where draft must be kept to a minimum. In many cases, it is possible to achieve a draft that is close to zero in specific areas. When designing your component, try to keep draft in mind at all times and use liberal draft in non-critical areas from the beginning.
Fillets and Radii are two terms that are used to describe the shape of a filter or a radius
Also, remember to incorporate fillets and radii into the design of your component. Make use of generous fillets and radii wherever it is possible, especially in non-critical areas. In the event that a fillet or radius is not possible or desirable in a particular area, make a note of it on your component drawing. Filets and radii help to strengthen the component, improve metal flow, and make the application of subsequent finishes more straightforward.
Ribs and Bosses are two of the most important words in the English language
It is common practice to incorporate ribs and bosses into part design to increase the strength of a component's structural integrity. To the greatest extent possible, they should be blended with fillets and radii to eliminate sharp corners. Because the majority of ribs and bosses have non-critical side surfaces, it is important to apply draft in the appropriate manner.
Pockets are a type of storage space
If the part that is being designed must be lightweight, one option that is frequently used is to incorporate pockets into solid sections of the part. Besides reducing the weight of the part, this also reduces cycle time and lowers the cost of manufacturing the part. Make certain to apply the appropriate draft and radii once more.
When designing a die cast component, consider all of the advantages and disadvantages of the process as a whole. Consider including features that will incur little or no additional expense. Logos, surface textures, integrated fasteners (rivets, studs), embossed part numbers, and other design elements are examples. Even greater adaptability is possible with the 4-slide die casting process. Your technical representative can assist you with all of these options and others as necessary.
