MHM Ltd - A Culture of Quality

Maintaining the Highest Standards for Almost 70 Years

Consistent quality is ensured because we control ALL stages of manufacture from the raw powder arriving in our factory. This provides us with 100 % traceability.
We have the latest ISO 9001:2008 accreditation and have held an ISO certificate for almost 20 years.
Our production and quality control procedures have been audited by leading oilfield and aerospace companies.
Only highest quality raw material is used in the production of components.
All products are hot isostatically pressed (HIP) to remove internal porosity.
A test piece is sintered from each alloy and laboratory approved before production commences.
Components are inspected at various stages of manufacture.
Inspection facilities include die penetrant, ultrasonic, Vickers and Rockwell 'A' hardness, fracture toughness, coercive force, photographic, grain and microstructural apparatus.
A 'culture of quality' ensures that components are strictly to customer drawings.
