Reduce Manufacturing Costs with the Right Die Casting Design

Posted by sunainaram on September 16th, 2015

In the die casting process, molten metal is poured into a mould that is designed in the shape of end product. The molten metal is injected at very high pressure into the mould, so it takes up the shape of the mould. This die casting process is efficient and economical as it saves time, effort and also decreases wastage at the same time. Different metals such as zinc, tin, magnesium and aluminium as well as their alloys are used in the die casting process.

There are small steps that you can take to further reduce aluminium die casting process expenses. The entire production process can be made less costly by making subtle changes in the die casting design.

Reduce the Weight

When you reduce the volume of components required for die casting, you can proportionately decrease the weight and cost of die casting. If you pour more metal into the cast, then it will take more time to set and cool, which will eat up into your production time. So, you can go for slight alterations in the die casting design like designing pockets to make thinner cross sections or use ribs to strengthen the cast product. Care should be taken while designing the location of the pockets because the wrong positioning of the pockets can affect the product’s accuracy and strength.

Parting Lines and Ejector Pins

While designing the aluminium die castings, careful consideration should be given to the parting lines and ejector pins. The parting line should preferably be straight or flat, so removal becomes easy. Ejector pins are used to remove the cast products from the mould. If the pins are neatly designed, then they will not leave any marks on the cast when it is removed from the mould. So, you finished product will not have any unnecessary marks and scratches which could then require another finishing touch.

Radii and Fillets

While creating the <a href="http://www.dynacast.com.sg/die-casting-design">die casting design</a>, care should be taken to avoid sharp corners. If there are less sharp corners in the <a href="

Also, there should not be quick ups and downs in the cross section, which will lead to erratic flow of molten metal in the cast, and finally lead to an irregular finish.

There are lots of the other techniques that can be used while designing the cast. These techniques will not only ensure product strength, but also reduce production time and decrease manufacturing costs.
