This process will turn the molten aluminum into a steel die. It will go through machining and finishing so a precise aluminum mold will be formed.

  • Permanent Mold Casting

This is to finish the mold for the product to be made. It will involve cores of metals or steel. It is important that the product molded is easily removed from the mold. This is when semi-permanent mold casting techniques are used.

  • Sand Casting

This is the most versatile process in using aluminum for investment casting. Though this process is slow, it is more economical.

Industries these days are lucky to have better and useful machines so investment casting can be made easily. And now that aluminum investment casting is becoming more popular, more trades and businesses are looking into switching to this process. Though the other castings are also useful, many design engineers prefer the one that will fit perfectly with the product to be made. Aluminum’s versatility and strength make it a suitable material for any design molds and form.


With the need to create the tool, aluminum is easy to melt, machine, and modify. It makes the entire process fast to accomplish creating more end products more speedily. The popularity of aluminum investment casting makes it an in-demand process in many industries. With the versatility and other features of aluminum, it makes a good choice in making any complex forms and designs needed. Therefore, it has become a common choice among design engineers. Aluminum investment casting provides a lot of benefits and efficiencies to industries. Its purposes extend to different businesses, trades, and industries.
