Minimize the costs for deep drawing process: experts’ advice
Those who are familiar with this domain know that sometimes the costs for manufacturing parts using the deep drawing process can be quite high and in many cases this can seriously affect the business. This is the reason why some experts in this industry decided to share some of their opinions and offer people some great advice in order to reduce the costs of manufacturing deep drawn parts.
One primary aspect manufacturers have to pay attention to is the engineered scrap that results from manufacturing a blank. They should focus on this facet, calculate the amount of scrap and the blank size and try optimizing it, since by doing so, the final part cost is significantly reduced and more parts can be used using the same amount of material.
Another important cost saving tip experts provide is related to including in the design phase the amount of material that is going to thin and thicken. Throughout the forming phase of the manufacturing process, some sections of the material may either thicken or thin towards the open end, respectively the closed end of the shape. Knowing about this aspect from the very beginning, the design phase can actually help the amount of scrap to not exceed the estimated quantity and the design to work accordingly.
When it comes to deep drawn metal stampings, it is highly recommended to choose the right type of material in order to benefit from the desired results. Going for a more form-able type of material and tempering the draw process can actually help you minimize scrap and in many cases even eliminate it. It is important to choose the exact type of material needed for the specific deep drawing process, because this way the results will meet the expectations. For instance, aluminium is recommended in certain situations because it can be better tempered in order to increase the quality of mechanical properties, whereas in other situations stainless strain is a better option when parts that need to be hardened when formed are manufactured. Choosing materials that are of superior quality can be a better investment in the long term, because there are high chances for the manufacturing costs to be lower.
Last but not least, upgrading your tooling to provide a minimum number of draws is also a great way to save costs. A part has its size reduced with respect to the length, width and diameter of the part every time it goes through the drawing process.
There are various companies on the market that provide deep drawing services and one very good example is National Manufacturing Co., Inc.. Those who are interested in deep drawn parts should keep in mind that they can only benefit from products of the highest quality if only they work with the best deep drawn manufacturer on the market. This means that they should do some detailed online research, ask for some recommendations and go for the best company in this industry that matches their needs, budget and interests.
