Overview of Services

Cti provides a suite of testing to meet the needs of casting producers, users and suppliers.  These services encompass all parts of casting production, from mould manufacture to the assessment of castings in use.

Accompanying the expertise held within the castings field, many of the testing services are covered by independent quality bodies including BSI, UKAS and Nadcap (GE Aero Engines & Rolls Royce).

Non-Destructive Testing

A host of Non-Destructive Testing techniques are available on components of different sizes and alloys.  Surface inspection is regularly conducted using Magnetic Particle Inspection (MPI) and Dye Penetrant Inspection (DPI).  Sub-surface defects in sections up to around 250mm thick (Steel) are identified using X-ray and Ultrasonic Testing (UT). 

In addition to the routine testing, other more diverse methods have been utilised, such as real-time radiography of liquid metal filling ‘real’ moulds.

Metallurgical

Cti have developed an un-rivalled knowledge covering a wide variety of metals and alloys, frequently handling steel, iron, nickel, copper, aluminium, titanium and magnesium alloys.

There are few problems related to castings that we have not seen before.  With many years experience within the metal casting industry, we have the ability to conduct a wide range of testing, usually as part of an investigation or assessment.  This knowledge enables us to not only provide results of analysis, but diagnose the root cause of defects / failures and to prescribe effective solutions.

Sand

Testing of both green sand and resin bonded sand systems is an essential part of foundry control, impacting directly on casting quality.  Cti have extensive facilities for the testing of such moulding materials, allowing the analysis and benchmarking of different sand systems and effectiveness of reclamation.

We recognise the importance of providing a fast and reliable service.  In achieving this, continuous dialog throughout work in progress is encouraged.  Such specialist knowledge is not available from other laboratories and testing facilities.
