Plastic Die Casting Machine

Die casting is a versatile process for producing engineered metal parts by forcing molten metal under high pressure into reusable steel molds. These molds called dies, can be designed to produce complex shapes with a high degree of accuracy and repeatability. Parts can be sharply defined with smooth or textured surfaces and are suitable for a wide variety of attractive and serviceable finishes.

A plastic die casting process is commonly in use today because of some its distinct advantages over plastic molding or other precesses. For instance, die casting produces stronger parts with closer tolerances that have greater stability and durability. Also, die cast parts have greater resistance to temperature extremes and superior electrical properties.

The basic die casting process consists of injecting molten plastic under high pressure into a 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.

Regardless of their size, the only fundamental difference in die casting machines is the method used to inject molten plastic into a die. The two methods are hot chamber or cold chamber. A complete die casting cycle can vary from less than one second for small components weighing less than an ounce, to two-to-three minutes for a casting of several pounds, making die casting the fastest technique available for producing precise non-ferrous metal parts.

The Advantages of Die Casting :
Die casting is an efficient, economical process offering a broader range of shapes and components than any other manufacturing technique. Parts have long service life and may be designed to complement the visual appeal of the surrounding part.

• High-speed production
• Complex shapes within closer tolerances than many other mass production processes
• Dimensional accuracy and stability
• The End products are heat resistant and stronger (than plastic injection moldings having the same dimensions)
• Multiple finishing techniques like smooth or textured surfaces and can be easily plated or finished with a minimum of surface preparation
• Simplified Assembly
