Quality is controlled throughout our investment casting process, from incoming material and wax preparation to melting, heat treatment, machining, final inspection and dispatch.
Our objective is not only to inspect quality at the end of production, but to control it throughout the manufacturing process.
Material chemistry, mechanical properties, dimensional conformity and casting integrity are verified according to customer and application requirements.
Material chemistry is verified using ferrous and non-ferrous base spectrometer facilities capable of analysing up to 32 elements. Heat chemistry is checked against the specified material grade before release.
Spectrometer analysisCast and machined components are inspected against customer drawings using appropriate measuring instruments, gauges and inspection fixtures. First Article Inspection and dimensional reports can be supplied on request.
Drawing conformityMechanical properties can be evaluated using a Universal Testing Machine with electronic extensometers. Tensile strength, yield strength and elongation are verified as required by the applicable specification.
UTM with extensometerBrinell and Rockwell hardness testing is available to verify material condition and post-heat-treatment properties against specified requirements.
Brinell and RockwellImpact testing is available up to 300 J to evaluate material toughness according to the applicable test standard and customer requirement.
Capacity up to 300 JCastings are visually inspected for surface discontinuities, incomplete filling, cracks, inclusions and other visible defects before further processing and final dispatch.
Stage-wise inspectionLiquid Penetrant Testing and Magnetic Particle Testing are available for surface defect detection. Ultrasonic Testing and Radiographic Testing can be arranged when specified by the customer.
NDT as requiredMaterial Test Certificates, chemical analysis reports, mechanical test results, hardness reports, dimensional inspection reports and applicable NDT reports can be supplied with dispatch.
Documentation availableFacilities used for material verification and mechanical property evaluation.
Ferrous and non-ferrous base spectrometer facility for material chemistry analysis of up to 32 elements.
Universal Testing Machine with electronic extensometers for tensile and mechanical property testing.
Impact testing facility for evaluating material toughness according to the applicable specification.
NDT methods are selected according to component geometry, material, service condition and customer specification.
Used to identify surface-breaking discontinuities in non-porous cast components.
Used for detecting surface and near-surface discontinuities in ferromagnetic materials.
Available where internal soundness verification is required by the applicable specification.
Available for internal defect evaluation when required by drawing, standard or customer inspection plan.
Testing is performed in-house where facilities are available or arranged through approved or accredited laboratories according to the agreed inspection plan.
Heat-treatment cycles are selected according to alloy grade, required mechanical properties and customer specification.
Heat treatment can be carried out according to material grade, drawing requirements and applicable customer specifications — available in-house or through approved processing partners. Process records and hardness verification can be provided where agreed.
Availability of individual processes may depend on component size, alloy and required specification.
Cast components can be supplied with cleaning, finishing and protective surface treatments according to end-use requirements.
Surface treatments are selected according to the casting alloy, corrosion resistance requirement, appearance, coating specification and intended service environment.
Inspection and production documentation can be prepared according to the customer's purchase order, drawing and agreed quality plan.
Documentation scope should be agreed at the enquiry or order stage.
Certified quality management system for the manufacture and supply of investment cast components. Customer audits and third-party inspection visits can be supported by prior arrangement.
Customer representatives and nominated third-party inspection agencies can be accommodated at agreed production and inspection stages. Inspection points, witness requirements and documentation should be finalised before order execution.
