Die Casting

Die casting is an efficient, economical process offering a broader range of shapes and components,also castings are among the highest volume, mass-produced item manufactured by the metalworking industry.With today’s modern die casting,we can produce a variety of sizes, shapes and wall thicknesses that are strong, durable and dimensionally precise parts. The Advantages of Die Casting: Parts have long service life. High-speed production Dimensional accuracy and stability Strength and weight Multiple finishing techniques Simplified Assembly Die casting VS. sand casting - Die casting produces parts with thinner walls, closer dimensional limits and smoother surfaces. Production is faster and labor costs per casting are lower. Finishing costs are also less. Die Casting Process The basic die casting process consists of injecting molten metal under high pressure into a steel mold called a die. Die casting machines are typically rated in clamping tons equal to the amount of pressure they can exert on the die. Machine sizes range from 400 tons to 4000 tons. Regardless of their size, the only fundamental difference in die casting machines is the method used to inject molten metal into a die. The two methods are hot chamber or cold chamber Choosing the Proper Alloy Each of the metal alloys available for die casting offer particular advantages for the completed part. Zinc - The easiest alloy to cast, it offers high ductility, high impact strength and is easily plated. Zinc is economical for small parts, has a low melting point and promotes long die life. Aluminum - This alloy is lightweight, while possessing high dimensional stability for complex shapes and thin walls. Aluminum has good corrosion resistance and mechanical properties, high thermal and electrical conductivity, as well as strength at high temperatures.
