How does Yindi compare to other die casting companies?
When looking for the best die casting company, customers not only search for the lowest costs, but they want quality parts, on time and they want to be able to communicate more easily with manufacturers. With knowledgeable and experienced die cast engineers who can design for manufacturing is important for our customers and for a successful project. From material selection to choosing the optimal process and eliminating secondary operations, our engineers work with each customer during the design process to make sure the part design will succeed in mass production.
Hot chamber and cold chamber die casting
High pressure die casting can be divided into cold-chamber die casting and hot-chamber die casting processes. In the cold-chamber process, molten metal is metered into a cold chamber for each machine cycle. The molten metal is then forced by a single plunger through a narrow feeder channel, into the die cavity itself, by the application of pressures from 7 to 207 MPa. The metal solidifies rapidly because the die is water-cooled within a fraction of a second. Upon solidification, the dies are opened and the casting is removed using ejector pins. Most of the castings will have flash where the two die halves come together. This is usually removed in a trimming die. The high cost of dies and the capital cost of machines limit this process to high volume production of components. Hot-chamber die casting is limited to the low melting point magnesium and zinc alloys, where contamination by the iron will be less extensive. A gooseneck shot sleeve is submerged in a heated pot of molten melt. A plunger descends and forces the molten metal into the die. As the piston retracts, the cylinder is filled with metal.
