Runpeng Precision Hardware understands quality products are key to business success. But there are some universal issues that can reduce the quality of die castings, which can result in a loss of profit. Today, we are going to talk about the five most common defects in die casting and how to resolve them.
How to overcome porosity in die casting?
One common defect in die cast parts is porosity, which can result in weak or failed parts under pressure. It happens when bubbles of air are captured in the metal as it is poured into the mold. Die casting porosity can be detected by small holes or voids on the surface.
To solve the problem of gas porosity in die castings, chassis or other casting products, it is necessary to degas the metal as it is cast. This will allow any air bubbles to be released. Furthermore, the adjustment of casting conditions, such as temperature and pressure, can also suppress porosity of the die casting.
COLD SHUTS IN DIE CAST PARTS: Understanding & Eliminating Defects
Another common defect in die cast parts that can happen when metal doesn’t come together during the casting process is cold shuts. This may form weak spots in the part that may allow the part to fail when put under pressure. Cold shuts can be recognized as seam lines on the outside of the part.
To get rid of cold shut defects in die castings, it is vital to achieve the element of the right temperature of the metal and to keep that temperature consistent during the casting process. Moreover, recasting and reconfiguring the part design for the proper flow of metal are practical means to reduce the cold shuts.
How to avoid inclusions and shrinkage in Die Casting
I include and shrinkage are defects that form during die casting as a result of foreign materials or impurities becoming caught in the metal as it solidifies. The presence of inclusions may result in the weakening of the part, and shrinkage can lead to dimensional inaccuracy. In order to avoid inclusions and shrinkage in die castings, high-quality metal, that is free of impurities is a must.
Dealing with Misruns in Die Casting Production
A defect that can occur during die cast production when molten metal fails to fill the mold cavity. This may produce under formed or deformed parts of parts we won't be able to use. In order to eliminate misruns during production of die castings, it is important that the metal be heated and kept at the right temperature. Furthermore, the casting conditions, as pressure and speed, can be also modified to avoid misruns.
Addressing Parting Line Defects to Achieve Better Profitability in Die Casting Processes
Parting line The parting line is the area where the two halves of the die meet, and parting line defects (often simply called line defects) are a consequence of the molten metal reaching this area and cooling. This may result in a less aesthetically appealing part and/or one of less quality. If you are a parting line of die-cast CNC Machining molding process to improve the quality is the most important is that two halves of the mold are exactly straight alignment, good performance. In addition, the application of high quality mold materials can also decrease the occurrences of parting line defects.
In summary, through eliminating these typical die casting defects, companies will discover the quality of their products increasing and their bottom lines improving. At Runpeng Precision Hardware, we know the value of getting quality die castings and we want your business to be successful in everything you do. By implementing the tips given above, companies can avoid defects in die castings and create parts to the highest quality standards for a satisfied customer.
