Machine Quality Assurance

Start your project

When parts put into service are defective, processes or equipment may fail. This can lead to lower productivity, shutdowns, and environmental incidents. Quality control in CNC machining is a must!

Marberry Machine wants the machined components or fabricated assemblies manufactured at our facility to fit, form, and function as intended. Consequently, we offer an extensive array of services to confirm material integrity.

Non-Destructive Testing

Non-destructive testing, or NDT, is the process of inspecting raw materials, finished components, and welded areas for discontinuities without destroying serviceability. Also called non-destructive examination, or NDE, it’s suitable finding flaws at, near, or below the inspected item’s surface.

Marberry Machine brings in independent, ASNT SNT-TC-1A Level II-certified inspectors to perform NDT. Common examination types offered include:

  • Visual Testing, or VT
  • Liquid Penetrant Inspection, or LPI
  • Magnetic Particle Inspection, or MPI
  • Ultrasonic Testing, or UT
  • Radiographic Testing, or RT

Metallurgical Testing

Metallurgical testing identifies the chemical and mechanical condition of materials, which helps ensure that products or components are fit for purpose. It can also verify raw materials received are in what was promised by a supplier.

These examinations are done in-house or at approved laboratories, depending on the method performed. Types of metallurgical testing include:

  • Chemical Testing
  • Hardness Testing
  • Bend Testing
  • Surface Finish Verification
  • Microstructure Testing
  • Impact Testing
  • Grain Size Confirmation
  • Fatigue Testing
  • Tensile Testing
  • Wear Testing
  • Corrosion Resistance Testing 

Functional Testing

Functional testing provides a pass-or-fail determination on semi-finished or fully finished products to prove functionality before shipment. It simulates the operating environment for the tested item. Any nonconformities, such as leaks, can be resolved on site instead of in the field.

These tests are done in-house or at approved facilities, depending on the method performed. Types of functional testing include:

  • Pressure Testing
  • Hydro Testing
  • Hydrostatic Testing
  • Open or Close Testing
