Precision of Metal Molds Influences the Standard of Die Casting Production Quality

Fundamentally speaking, Die Casting is a process used for creating metal parts by forcing molten metal into a mold cavity through an application of high pressure. The mold cavity is manufactured using two hardened tool steel dies that are previously machined into shape according to specifications for the part/product. Most die castings are made of non-ferrous metals (an absence of iron), such as:

  • Zinc
  • Copper
  • Aluminum
  • Magnesium
  • Tin-based alloys
  • Lead-based alloys
Die Casting Mold

Based on the type of metal or metal alloy to be used, the die casting process will encompass one of two following methodologies:

Hot-Chamber Die Casting – in this process, a pool of molten metal is fed/ into the mold through pressure that is applied by a pneumatic-powered or hydraulic-powered piston. It is an advantageous method due to its fast cycle times, up to 15 cycles per minute on average, and the convenience of melting the metal directly in the chamber/machine. Conversely, the use of hot-chamber machines is limited to low-melting point metals only, which eliminates aluminum die casting as an option.

Cold-Chamber Die Casting – this method requires the metal to be melted in a separate furnace then transported in precise amounts to the cold-chamber machine. This molten metal is then injected or shot into the mold by hydraulic or mechanical pistons. This system is ideal for use with aluminum and zinc alloys containing large concentrations of aluminum, magnesium, and copper. Its primary disadvantage is longer cycle times, due to the need to transfer the molten metal from a furnace to the machine.

5 Axis CNC Machining die casting

Die casting is used to manufacture a wide variety of products in numerous shapes/sizes. The following are but a few examples within the range of outputs from this process:

  • Firearms
  • Golf clubs
  • Gear shifters
  • Medical devices
  • Locks and deadbolts
  • Drone camera housings
  • Industrial pumps, compressors

In order to make these types of items, particularly with the production volumes, efficiencies, and tolerances expected by their clients and/or end-users. Manufacturers will need mold cavities that are very precise in design; products that are delivered with irregularities or of inferior quality will likely be rejected, along with any and all invoice for services rendered.

Thus, manufacturers who rely upon metal molds/die casting within their business operations may want to consult with the precision mold making, die casting, and tooling specialists at Noble Precision. In order to ensure the highest standards of quality and accuracy for their products.

Cutting-Edge Technology and Related Services to Support Your Die Casting Needs

Although the manufacture of parts/products using die casting can be a relatively straight-forward process. It is all predicated on significant capital costs for the die casting equipment and the metal dies/molds. And while a manufacturer might have the resources to invest in this equipment, and the plans/strategies to recover and surpass their investment. All can be for naught if the precision and quality of the mold is anything less than the highest degree.

Consequently, manufacturers may want to capitalize on the mold-making expertise of Noble Precision. Supported by Noble’s substantial investment in state-of-the-art technology. Such as the latest in 5-axis simultaneous CNC machines and CAD/CAM software. This will in turn allow their clients to benefit from the most advanced and accurate machining methodology with respect to:

  • Metal mold-making
  • Metal finishing services
  • Die casting and tooling services
  • And much more …
