Benefits of Precision Casting

What is the benefits of precision casting?

Precision casting is one of the casting methods.

Compared with traditional casting technology, precision casting is a special casting method.It can obtain relatively accurate shape and high casting accuracy together.The more common method is:

  • According to the product requirements to plan and make mold (margin is very small or no margin), using the casting method to cast wax to get the original wax mold;
  • Repeat coating and grinding on the wax mold to harden the shell and dry;
  • The inside of the wax mould is then melted to remove the wax and obtain the cavity.
  • Roast shell to obtain satisfactory strength and air permeability;
  • Metal materials needed for fine casting;
  • The sand is cleaned after the shell to obtain a high precision finished product. According to product requirements or heat treatment and cold working.

The following is to introduce the advantages of precision casting.

  • 1. Precision casting has a wide range of applications, which is not restricted by the scale, thickness and complexity of the casting, and the production mode is convenient.
  • 2. Precision fine casting can use a variety of materials, including steel, iron, aluminum, copper, gold, silver and so on, and their alloys can be cast. Compared with the ordinary casting method, it consumes less.
  • 3. The casting has certain scale accuracy, small machining allowance, saving the processing time and metal materials.
  • 4. Low cost, good overall economic benefit, low energy consumption and less consumables.
  • 5. Fine Casting is capable of casting superalloy castings, such as jet engine blades, streamlined profiles and cooling chambers, which are difficult to assemble through machining skills. However, the use of fine casting skills can not only achieve mass production, ensure the consistency of the casting, and can avoid the residue after processing.
  • 6. Fine casting has high scale precision and surface finish, which can reduce the processing workload. Parts that satisfy a small number of requirements require only a small number of machining allowances. Even some castings can be processed without mechanical processing, leaving only polishing and polishing allowance. It can be seen that fine precision casting can save a lot of machine tools and processing time, and greatly save metal raw materials.
