Precision Casting, Also Known As Investment Casting

  Precision casting, also known as investment casting

  Casting production Casting precision, surface finish, material density and microstructure, mechanical properties and other aspects are often poor, so when the casting of these performance requirements higher, should use other casting methods, such as melting (lost wax) Casting, die-casting, low-pressure casting, etc., the following for everyone:

  Precision casting of the characteristics and advantages:

  Precision casting, also known as investment casting, with other casting methods and parts forming method compared to investment casting has the following characteristics:

  1. Casting size accuracy, surface roughness value is fine, the size of the casting can reach 4-6 level, surface roughness up to 0.4-3.2μm, can greatly reduce the casting allowance, and can achieve no margin manufacturing, reduce manufacturing cost.

  2. Castable shapes are complex and difficult to use other methods of processing castings. Casting outline size as small as a few millimeters to thousands of millimeters, wall thickness of the smallest 0.5mm, the smallest hole by 1.0mm or less.

  Alloy materials such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and superalloy, titanium alloy and precious metals can be used for casting production.For difficult forging, welding and cutting alloy materials, more Is particularly suitable for casting production.

  4. Production flexibility, adaptability. Can be used for mass production, but also for small quantities or even single production.

  In summary, precision casting has the advantages of small investment scale, large production capacity, low production cost, simple process of complex products and quick investment, so as to be in a favorable position in competition with other processes and production methods. The
