HOW TO MAKE ALUMINUM MOLDS

 With the rapid development of the manufacturing industry, the aluminum alloy die-casting industry has also obtained many development opportunities, especially the aluminum alloy die-casting castings have been widely used. So what are the manufacturing processes of Aluminum molds? What other matters need attention? Let’s find out together

What is a Die Cast Aluminum Mold?

Die Cast Aluminum Molds is also commonly known as Dies. These molds are used for the mass-production of aluminum parts. Mold making used to be a difficult task before. Thanks to the CNC Machining technology mold making is now faster and more efficient than ever.

Aluminum Die casting Mould requires a material that has higher strength and melting temperature than Aluminum. Otherwise, the die will be damaged during the casting process. Usually, steel molds are used for aluminum die casting.

High-quality steel is quite costly and hard to machine. So, the die tooling cost is relatively high. Even though the high tooling cost, aluminum die casting toolings provides the best economy and quality for large volume production.

How To Make Aluminum Molds

Aluminum mold design: divided into product distribution, runner design, slider, thimble, exhaust, slag design, etc. This requires the mold designer to have sufficient professional experience and familiarity with the product, so that the designed aluminum alloy die-casting mold can have a positive impact on the service life and die-casting products

Aluminum mold design drawing: draw all the parts and accessories of the aluminum alloy die-casting mold one by one, first draw the three-dimensional drawing, and then draw the two-dimensional drawing. After the drawing is completed, the design is checked first, and then the supervisor of the mold department, the corresponding engineer of the project and the company check the drawing to ensure the smooth production of aluminum alloy die-casting molds

Aluminum mold processing: mold processing is divided into mold base processing, mold core (mold core) processing, thimble, slider and other accessories processing. In addition, it is also necessary to use mold manufacturing equipment such as electric discharge machine, milling machine, grinding machine, numerical control, heat treatment, etc.

Assembling the aluminum mold: This section requires the smooth completion of the previous process and the completion of various accessories, usually completed by the assembler responsible for the set of molds. This assumes that the assembler is very familiar with such molds, has some experience, and has a good understanding of drawings, assembly techniques and various mold making machines. Otherwise, assemblers cannot handle it independently during assembly, and experienced assemblers can often assemble a set of molds independently in the face of various problems

Aluminum mold real mold: After the mold assembly is completed, the corresponding die-casting machine should be set up to match the production and actual mold progress, and the mold should be tested for T1. Here, the person in charge of the die-casting department and the assemblers, engineers and business personnel in charge of the mold group should help to complete, and the quality inspection should be carried out after the sample is cooled.

Product inspection after aluminum mold trial: This process must be carried out jointly by quality personnel, engineers and the company. If the precision, appearance, and structure of the product conform to the design parameters of the mold and are considered qualified, the clerk can send it to the customer for inspection and acceptance. If not, it is necessary for the mold designer, mold manager and fitter to discuss improvements and solutions together until the product is qualified

Advantages of  Aluminum Die Cast Mold

Aluminum die cast mould has made the production of aluminum parts a lot easier. Some of the benefits of die casting molds are explained below.

• A single mold can produce thousands of parts
• Can produce parts with very tight tolerances
• Can withstand high temperatures
• Can withstand very high pressure
• Significantly reduces production cost for large volume production
• Can manufacture multiple aluminum parts at one go
• Increased rate of cooling and solidification allows faster production

For these multiple advantages, aluminum die-cast mold is being used for boosting aluminum die casting capacity.
