Die casting forces molten metal into mold cavities under high pressure. Aluminum die casting and alloy die casting are the most common forms. Other metals die castings use zinc, copper, magnesium and lead, all of which are non-ferrous metals.
Die casting creates many small- to- medium-sized parts that are all the same and have fine detail, making die casting one of the highest-volume products in the metalworking industry. Before proceeding with a die casting job, be aware of some basic issues, and decide whether you will be purchasing die casting machinery for your shop, or whether you will be using the services of a die casting company.
1. Look for die casting machines that can achieve precise tolerances and accuracy if you are buying one to use in-house.
2. Find a die casting manufacturer with a long-standing reputation for excellence if you are outsourcing.
3. Seek out a die casting distributor of imported castings to save money and ensure quality.
Purchase a pressure die casting machine with precise tolerancesDie castings should have uniform wall thicknesses and cores of simple shapes. Dies should not come out uneven or weak, and the molds should have a draft allowance that lets the die come out easily. Make sure the machine you buy can work to these standards.
Connect with die casting manufacturers with long-term experience and a great reputationThe longer a company has been in business, the more time it has had to gain a good reputation, grow and become more innovative. The fact that a company has a history of customers which goes back many decades speaks volumes about the company's trustworthiness in providing quality products and services.
