Calibration intervals & IATF 16949
Setting intervals and satisfying clauses 7.1.5.3.1 / 7.1.5.3.2, including the OEM route.
Read the guide →Calibration traceability & certificates
The chain to national standards, what a good certificate shows, and QR verification.
Read the guide →Sand testing instruments
Sand strength machine (green compression strength) calibration
Verifying the force path of the universal sand strength machine and GCS targets.
Read the guide →Permeability meter calibration
The traceable-nozzle method, the monthly primary check and leak errors.
Read the guide →Moisture, compactability & clay-test calibration
Balances, driers, rammers and sieves behind moisture, compactability and clay.

Hardness tester calibration (Brinell, Rockwell, Vickers)
Brinell / Rockwell / Vickers to ISO 6506/6508/6507 with traceable blocks.
Read the guide →Casting defects
Casting defects: types, causes and prevention
Types of casting defects - gas, shrinkage, sand, pouring, inclusions - with a page for each.
Read the guide →Blowholes in castings
Smooth-walled gas cavities: how to tell them from shrinkage, and how to prevent them.
Read the guide →Shrinkage porosity in castings
Spongy voids at thermal hot spots, and the feeding and gating that fix them.
Read the guide →Sand inclusion casting defect
Loose mould sand trapped in the casting - mould strength, erosion and clean closing.
Read the guide →Cold shut casting defect
Two streams that met but did not fuse - pouring temperature, speed and gating.
Read the guide →Misrun casting defect
An incompletely filled casting - fluidity, venting and thin-section filling.
Read the guide →Metal penetration casting defect
Metal forced into the sand - grain fineness, ramming, temperature and coatings.
Read the guide →The casting defect register
Recording and naming rejections consistently, down to the cavity and heat, so the cause is findable.
Read the guide →Cavity-wise rejection analysis
One impression rejecting more than its neighbours - the cleanest comparison a foundry has.
Read the guide →Sand properties and casting defects
Which sand property drives which defect, and how to read the sand lab against the register.
Read the guide →Foundry rejection analysis
Ranking, slicing by pattern, shift, heat and cavity, and checking the corrective action held.
Read the guide →Identifying casting defects
Naming a defect at the bench: families, the tells that separate confusable pairs, and when to say unknown.
Read the guide →Heat-wise rejection analysis
Grouping defects by heat to tell a melt problem from a mould problem, including fade within a heat.
Read the guide →Calibrate with the people who build the equipment
Versatile Equipments manufactures foundry sand testing and metallurgical instruments and calibrates them with traceable certificates - the original-equipment-manufacturer route recognised under IATF 16949 cl. 7.1.5.3.2.
