Introduction

• Die casting is the Metal forming process in which
  molten metal is forced into a cavity or mold
  under high pressure. This takes place under high
  pressure which is applied to the molten metal
  which is inserted into mold cavity.
• Die casting is an efficient, economical process
  offering a broader range of shapes and components
  than any other manufacturing technique.

Process

• Die casting provides complex shapes within closer
  tolerances than many other mass production
  processes. Little or no machining is required and
  thousands of identical castings can be produced
  before additional tooling is required.
• Die casting is one of the most versatile and
  prolific metalworking processes, creating
  countless varieties of parts used in almost every
  industry imaginable. Interestingly enough, it
  dates back to the mid 1800s, and today,
  innovations keep it moving forward.

The Hot Chamber Die Casting Process

• Hot chamber die casting is one of the two
• main techniques in the manufacturing
• process of die casting, Hot chamber die
• casting has the advantage of a very high rate
• of productivity. During industrial
• manufacture by this process one of the
• disadvantages is that the setup requires that
• critical parts of the mechanical apparatus,
• (such as the plunger), must be continuously
• submersed in molten material.

The Vacuum Die Casting Process

• Vacuum casting creates good
• conditions for decisively reducing gas
• porosity, since air is evacuated from the
• die cavity. Depending on the alloy used,
• the required values may be achieved in
• vacuum casting even without additional
• heat treatment. But if such treatment is
• necessary, it will produce surface flaws
• in the presence of even minor gas
• porosity, which cannot be tolerated on
• the end product.

The Cold Chamber Die Casting Process

• Cold chamber die casting is a permanent
• mold metal casting process. A reusable
• mold, gating system and all, is employed. It
• is most likely machined precisely from two
• steel blocks. Large robust machines are used
• to exert the great clamping force necessary
• to hold the two halves of the mold together
• against the tremendous pressures exerted
• during the manufacturing process.

10
The Low Pressure Die Casting Process

• Low pressure die casting is competitive casting
  method when the production quantity is relatively
  small and/or when heat treatment is needed to
  improve the mechanical properties. The tolerances
  and the surface finish are the same as achieved
  by gravity die casting. The tooling costs are
  somewhat higher than by sand casting.

What Are The Benefits of Die Casting?

• The benefits of using die casting over other
  methods of part
• production are numerous. Die casting provides
  cost-effective
• solutions to create parts that have complex
  shapes, parts that require
• a high heat tolerance, and also allows us to
  produce a part with
• tighter and stricter tolerances. Die casting
  historically has inherently
• produced less scrap and requires less machining
  than machining
• parts our of raw billets. When compared with
  forgings, plastic
• injections, stampings, etc, die casting is the
  clear choice for superior
• part quality with a low cost. Die casting
  produces parts with excellent
• strength to weight ratios and allows for many
  different finishing
• capabilities.
