Using China die casting mold requires special equipment because it is a highly corrosive and highly heated procedure. The temperature of molten aluminum is maintained at 1,100 degrees Fahrenheit/593 degrees Celsius, that of molten magnesium at 1,250 degrees Fahrenheit/677 degrees Celsius, and that of die temperatures at 350 degrees Fahrenheit/177 degrees Celsius, respectively. One of the most significant and persistent issues that die casters have to deal with on a regular basis is die soldering (also known as die sticking), which is a problem that occurs in the https://www.diecasting-mould.com/cnc-machining-service cnc machining industry. When molten metal is brought into contact with the surface of a die or die component, it has been observed that the steel is heated above its soldering critical temperature, causing iron to dissolve into the melt while, at the same time, molten metal diffuses into the die surface, resulting in the formation of a layer of intermetallics at the interface between the metals. https://www.youtube.com/watch?v=1543I_5XMJo Die casters have reported that corrosion caused by die soldering (also known as "die sticking") is one of the most persistent issues they have encountered. It is known as die soldering (also known as die sticking) and occurs when molten metal welds to the surface of an extrusion die, resulting in part sticking, tool and component damage (including the die), and a poor surface on the part. For the problem to be resolved, casters must frequently stop their process in order to clean the die and its components, and some of the components must be replaced on a regular basis. Increased costs and scrap rates are the result, as is a loss of process and shot-size stability, as well as a higher overall cost of quality, to name a few of the consequences. Furthermore, die casters are required to keep large inventories of spare parts on hand for emergencies.During the course of time, this layer thickens and gets increasingly thick. After they have been allowed to cool, the molten metal solidifies and interlocks at their surfaces, effectively welding the two components together. This results in components sticking to one another while castings have poor surface finish due to tooling damage. While going through this reaction, the die and its components become more susceptible to microcracks and pits, and the walls of the die and its components become thinner and weaker, necessitating the need for constant cleaning. The result is that a typical aluminum casting die will only last for 100,000-150,000 aluminum parts and 200,000-300,000 magnesium parts before requiring significant repairs or replacement. A properly maintained steel injection mold, on the other hand, can produce a million shots before needing to be repaired or completely replaced.One classic example of the soldering issue is what can happen to core pins, which are used in the casting process to create holes in the part in order to reduce the need for secondary drilling. Core pins are used to create holes in cast parts in order to reduce the amount of secondary drilling required later on. Several large jobs in magnesium were being produced at the Twin City Monticello plant, according to Dan Sheridan, toolroom/die repair supervisor at the company's Monticello facility. The project in question involved the design and manufacture of a two-piece frame for the center display panel on passenger vehicles that measured approximately 6 by 6 inches/15 by 15 centimeters. Stopping the casting process on a regular basis was necessary in order to clean and polish the core pins in order to reduce the likelihood of soldering occurring during the casting process. Twin City was producing 240,000 pieces per year, and their four-cavity die used four custom core pins per cavity, so the downtime and productivity losses were becoming unaffordable.We'd already experimented with a number of high-end coated products that, as Sheridan explained, didn't last very long after they were applied. We were becoming more and more irritated by the minute. Once the protective coating began to flake away after a short period of time, the benefits would be lost for good. As a result, we were having to shut down the facility three or four times per shift in order to clean and polish the core pins. This was necessary because our parts were becoming out of specification, and it took us an average of 45 minutes to clean and polish them each time we went into them. Even worse, we had to swap out those pins on a monthly basis, which was extremely inconvenient for everyone involved. As a result of this seemingly never-ending cycle, the organization experienced significant downtime, scrap parts, and frustration.
