Knowing in details about pressure die casting

When it comes to naming the top processes happening across the metal industry, pressure die casting comes as one of the preferred names. The manufacturing activity utilizes high pressure for melting the metal and forcing the liquid to flow within a steel cavity (popularly called mold). The high degree of precision, cost-effectiveness, and smooth finishes are the primary reasons any industry prefers going by this method.

Called in general press die casting, it is gaining a new name in the market. Therefore, read on to find more about it and understand the details associated with it.

Principle of working

The principle of die casting is quite straight-forward: inject the molten metal within a steel mold at very high pressure and allow it to solidify rapidly (starting from a few milliseconds to some seconds based on the net shape of the part). Post removal of the tool, the cast gets extracted and used based on the application area.

Again, based on the pressure applied, the pressure die casting is divided into low pressure and high pressure die casting. Some of the differences between the two include the following:

• 35 MPa pressure in a low pressure, whereas 150 MPa and above in the otherwise case. Accordingly, they find suitable applications for low and high melting point metals, respectively.
• Metal is held within the chamber for forced injection by the piston in the former case. In the latter, the molten metal is melted in a separate furnace and transferred into the chamber using a short sleeve.

Basis the requirements, the choice can be made for a particular variant of die casting.

Common materials used

Aluminum, zinc, and magnesium are some of the common materials that are used in the industry for this process. The following machining properties add numbers to the overall usability of the element:

• Zinc is the easiest metal for casting and maintaining fluidity at lower temperatures.
• Aluminum having plastic properties and eventually bending into multiple profiles of choices.
• Magnesium bearing the ability of quick machining and higher strength to weight ratio.

And when they are poured within the die-cast molds of hot die steel, the physical properties are enhanced. Therefore, they find particular applications in areas of high performance and enhanced durability of the materials.

Major applications

The following are some of the major applications found in the entire process:

• Aerospace engineered parts
• Automotive parts
• Kitchen tools
• General hardware equipment, like appliances, plumbing parts, pump parts, and others

Thus, if your brand belongs to any of these industries, then press die casting is the choice for you.

Taking the best services

Yes, you can choose any service available in the market for pressure die casting. Just keep in mind the following points before finalizing:

• A good name and brand value in the market
• Perfect costing to the companies (scope of incentives)
• Smooth finish on the jobs done
• Experience in the field
• Robust technology is used for carrying out complex activities

All in one, the overall process is highly efficient and needs to be focused upon further.
