Investment Casting Quality Control testing tools and Inspection items

EASIAHOME is ISO 9001:2015 certified. Our quality assurance system covers all activities from design, development, production, installation, service, and documentation.

What is the inspection of casting?

Each step in the metal casting process, from plate making to heat treatment, should be completed with care to avoid problems with the soundness, surface finish, mechanical properties and final dimensions of the finished casting. However, even carefully made castings should be subject to inspection for quality control. Minor problems can arise unexpectedly, and the mechanical requirements of many castings can be undermined by a hidden defect. Thus, in order to ensure the quality of metal casting parts products, a series of inspection means for precision casting inspection carried out in the various processes of production, never make casting inspection can make foundries and customers have confidence in the quality of their castings.

Visual inspection

Foundry casting visual inspection standard

Defects that are obvious when castings are visually inspected are: cracks, tears, slag adhesion, blow holes, metal penetration, crusting, shifting, unfilled, mold or core cracking, and similar defects can be inspected by visual criteria acceptance will be based on surface appearance only, in normal white light, by corrected vision of the naked eye to check whether the casting or casting and machined surfaces meet visual acceptance criteria.

If otherwise agreed between the customer and the foundry can include root mean square or AA values, consider the requirements for magnetic particle, fluorescent penetrant, radiographic or other non-destructive testing.

Dimensional inspection

  • Measuring tools
  • Testing gauge
  • CMM(Co-ordinate Measuring Machine)

CMMs are many times the only way to measure manufactured parts because they are very accurate and can measure to within a few microns. Following a program agreed with the customer, the CMM will measure the part consistently and accurately according to the drawn specifications.

Chemical composition inspection

Manufacturers and product assembly companies require specific chemical compositions for the precision investment casting products they use in their operations. These precise chemical composition requirements are necessary to ensure high-quality products that will not fail in their intended applications. Manufacturers who work with EASIAHOME’s expert precision casters can expect their products to meet their chemical composition requirements, while still maintaining superior product quality and reliability. Our chemical certification and testing services are available upon request.

EASIAHOME will thoroughly test the physical properties of your investment casting products to fully ensure that they meet the needs of your manufacturing center. We know that casting parts with specific chemistries is critical to ensure they maintain the highest standards for the desired application.

Destructive Testing

Non-Destructive Testing of Investment Mold Castings

Non-destructive testing (NDT) is a type of testing that is typically performed on molten die castings to ensure that the finished product meets specified quality standards. NDT involves testing a part without damaging or distorting it.

Benefits of Non-Destructive Testing (NDT) for Melt Mold Castings

There are many reasons why this type of testing is so important. Some of the reasons are listed below.

Overall product reliability is improved. Possible failure areas can be identified before problems occur. The product is not damaged during testing

Industries Served

We can provide NADCAP NDT services to a wide range of industries, including.

  • Aerospace
  • Medical
  • Energy Industry
  • Defense
  • Turbine Engines
