Leading Zinc Die Casting Companies

Zinc is the most commonly used die casting metal for many reasons. It is among the simplest alloys to cast, providing high impact strength, high ductility, and simple plating. Read More…

Zinc Die Casting Zinc die castings are shaped metal products that are shaped by machines called die casters. Die casters are metal formation machinery that take raw metals, heat them and then form them into usable products. Metal castings are some of the most important industrial products in existence. They serve as essential components in manufacturing equipment, helping to operate the machinery that assembles the industrial, commercial and consumer utilities that drive economies worldwide.

Precision die castings plus a multitude of related services, including engineering, designing, machining, finishing and assembly, occur at A and B Die Casting. Specializing in low to medium volume solutions, we also offer competitive prices.

What are Zinc Die Castings?

Zinc also has a lower melting point, meaning that lower heat can be used in the casting process, doing less harm to the die and enabling long die life. A long die lifespan means that a die can be utilized for longer durations before it has to be retooled, minimizing costs for business.

Zinc Die Casting

As with injection molding, the core of the operation is to create a tool, in this instance, a zinc die casting tool. It is a machine designed to operate in a challenging environment and can often be costly. However, these costs may be reduced by guaranteeing that the design is made “molding friendly” by a competent design team.

Die Casting is placing liquid metal into a die (like a mold) under high pressure to create sophisticated parts out of metal. Die casting is similar to injection molding, only with metal and not plastic.

Zinc Die Casting Process

The high-pressure zinc die casting procedure is done in an automatic machine fit to handle high pressure. The liquid metal is pushed inside a two-piece steel die with one or more cavities; each is an accurate inverse copy of the component or components.

The mechanical characteristics of pressure zinc die casting are usually superior to other casting procedures because of the rapid chill and quick solidification when the liquid metal comes in contact with the cooler steel side. Zinc can use both cold and hot chamber casting processes:

Hot Chamber Die Casting

In the zinc hot chamber die casting procedure, the injection instrument of a hot chamber machine is submerged in a liquid metal bath in a metal holding furnace. After the metal solidifies inside the cavity, the plunger is removed.

The die opens up, and the casting is ejected. The furnace is joined to the machinery by a metal feeding mechanism called a gooseneck.

Hot Chamber

The zinc hot chamber die casting processes can produce 4 or 5 shot outputs per minute.

Cold Chamber Die Casting

The cold chamber die casting method is the opposite of the hot chamber process. In cold chamber die casting, liquid metal is fed into the cold chamber or cylinder-shaped sleeve using a ladle. A hydraulically controlled plunger closes the cold chamber port, then forces the molten metal inside the die cavity under high pressure.

Cold Chamber

Accuracy and Considerations of Zinc Die Casting

The die casting process offers the ability to repeatedly create complete and highly accurate parts, making it a great choice for mass production.

Due to the advantages of zinc alloys, durable and dimensionally stable components are produced without compromising the requirement for close tolerances.

Dimensional Stability

  • Conventional zinc alloys have outstanding dimensional stability properties when cast.

Draft Angles

  • Zinc die castings help when considering draft angles.
  • Zinc alloys can be die cast with less draft angle than most competitive metals.
  • There are also certain instances where parts may be cast with zero draft angles. This is a major benefit when producing components in moving mechanical contacts like gears.


  • Zinc alloys offer superior thin wall castability since they have exceptional casting fluidity.


  • Zinc die casting produces parts with high degrees of accuracy and volume.
  • More often than not, it rivals machining tolerance and can be utilized to cast closer tolerance than any molded metal or plastic.

Advantages of Zinc Die Casting

There are many advantages of using Zinc die castings over others:

  • Wall sections are thinner than other metals due to high casting fluidity
  • High production rates
  • Few secondary machining processes
  • Smooth surfaces of finished products
  • Simple to cast inserts such as heating elements, threaded inserts, and high-strength bearing surfaces
  • Can cast low fluidity/viscous metals
  • Highly accurate dimensions
  • High tensile strengths

Applications of Zinc Die Casting

Many applications can use zinc die casting, including:

  • Interior automotive artistic parts
  • Engines and other hood components
  • Power steering systems
  • Brake parts and systems
  • Air conditioning components and systems
  • Fuel systems
  • Complex net-shaped housings
  • Electronic devices
