What is Die Casting ?
Die casting is a metal casting process that is characterized by the use of a mold cavity to apply high pressure to molten metal. The mold is usually machined from a stronger alloy, similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine is used
Die Casting Advantages
Die casting can have a big advantages compair to other manufacturing processes, which is lead a major cost savings, not only in the cost of die casting part but also in the overall cost of production. When you casting a part, you can create complex net shapes, Whatever your parts needs a external threads or complex internal features — Die casting can minimizing secondary operations. You can also combine multiple parts into a single part, eliminating assembly operations and lowering labor costs, with the added benefits of simplified stock control and greater component consistency.
1. Quality assurance
Die casting has the characteristics of high strength, high hardness, strength than sand casting increased by 25 ~ 30%, casting size tolerance by the mold control, high precision, dimensional stability, can die-casting thin-walled complex castings. For example, the current zinc alloy die casting minimum wall thickness up to 0.3mm; aluminum alloy castings up to 0.5mm; minimum cast out hole diameter of 0.7mm; minimum pitch of 0.75mm.
2. High production efficiency
Mechanization and automation, efficient machine productivity, ordinary horizontal cold air die-casting machine can die-cast 600-700 times in eight hours on average, small hot chamber die-casting machine can die-cast 3000-7000 times every eight hours on average; long life of die-casting type, one pay die-casting type, die-casting bell alloy, life can reach hundreds of thousands of times, even millions of times.
3. Excellent economic effect
Because the die casting size has high accuracy, surface finish and other advantages. Die-casting products can generally be used directly without further mechanical processing, which not only improves the metal utilization rate, but also reduces a large number of processing equipment and labor; and castings are cheap; can be used in combination die-casting to other metal or non-metallic materials. Both save assembly time and save metal.
Other benefits include:
Variable wall thicknesses
Fewer steps from raw material to finished part
Fast production cycle times
Reduction in material scrap
Die Casting Applications
Die casting is widely used in variety industries, making a variety of products, parts and shapes for a variety of industries, such as automotive manufacturing, electronics, building and construction, EMI shielding, HVAC, fixtures and plumbing, furniture, and industrial manufacturing. Customers value the durability, precision detail and consistently high quality of die cast parts.
