Casting Quality Control
and Certifications
Technocast Foundry is an ISO 9001, ISO 14001, ISO 45001, IATF 16949 and PED certified foundry in Coimbatore, Tamil Nadu, India. Every casting passes eight control points between raw material and the packing bay, checked in our own metallurgical lab, on two Brown and Sharpe coordinate measuring machines, and by in-house ultrasonic and magnetic particle testing.

Control Points
How Is Every Casting
Checked Before Despatch?
Eight control points sit between raw material and the packing bay. A casting that fails one does not move to the next.
Incoming Material
Pig iron, steel scrap, ferroalloys and moulding sand are checked against specification before they are accepted into the plant.
Sand Testing
Moulding sand is tested for strength, moisture and permeability on the shop floor. Sand controls surface finish and dimensional accuracy, so it is checked before it is used, not after.
Melt Chemistry
Every heat is analysed on an ARL spectrometer before it is poured. Grey iron, ductile (SG) iron and steel each have their own chemistry window, and the heat is corrected until it sits inside it.
Nodularity
Ductile iron is checked by ultrasonic velocity while the metal is still in the ladle, then confirmed under a microscope with image analyser for graphite shape, size and count.
Mechanical Properties
Tensile strength, elongation and hardness are tested on cast samples from the same heat. Digital micro Vickers is used where a local hardness reading is needed.
Soundness
Ultrasonic and magnetic particle inspection are carried out in house. Radiographic inspection is arranged through an accredited partner when the drawing calls for it.
Dimensions
Two Brown and Sharpe coordinate measuring machines, contour testing and ring gauge masters confirm the finished part matches the drawing before it leaves the machine shop.
Function and Packing
Pressure testing, load testing and dynamic balancing are carried out where the part needs them. The casting is then painted, packed and documented for despatch.
Equipment
What Testing Equipment
Does the Foundry Have?
All of it is on site at Arasur, Coimbatore. The one exception is radiographic inspection, which is outsourced to an accredited partner.
| Equipment | What it checks |
|---|---|
| ARL spectrometer | Chemical composition of every heat, before pouring |
| Sand testing equipment | Moulding sand strength, moisture and permeability |
| Microscope with image analyser | Graphite shape and count, and matrix structure |
| Ultrasonic velocity instrument | Nodularity check on ductile (SG) iron |
| Tensile and hardness testing machine | Tensile strength, elongation and hardness on cast samples |
| Digital micro Vickers | Local and case hardness readings |
| Brown and Sharpe CMM, 700 x 1,000 x 700 mm | Dimensional inspection with touch probe |
| Brown and Sharpe CMM, 1,500 x 1,200 x 1,000 mm | Dimensional inspection with scanning probe, plus gear profile testing |
| Ultrasonic and magnetic particle equipment | Internal and surface defects, in house |
| Radiographic inspection | Internal soundness where the drawing calls for RT. Outsourced to an accredited partner |
| Contour testing and ring gauge masters | Profile and bore checks against a master |
| Pressure testing rig | Leak testing on pump, valve and hydraulic bodies |
| 2,000 tonne hydraulic press | Load testing to customer specification |

Yes. Technocast holds IATF 16949:2016 alongside ISO 9001:2015, and supplies Tier-1 automotive customers on that basis.
Which quality certifications does the foundry hold?
Five: ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, IATF 16949:2016 and PED. All are current and independently audited.
Is non-destructive testing done in house?
Ultrasonic and magnetic particle inspection are done in house. Radiographic inspection is outsourced to an accredited partner and arranged when the drawing calls for it.
How is nodularity checked on ductile iron?
By ultrasonic velocity, then confirmed under a microscope with image analyser for graphite shape, size and count.
Can Technocast supply castings for pressure equipment in Europe?
Yes. The foundry is PED certified, which is required for castings that go into pressure-bearing equipment sold in the European Union.
What materials do the certificates cover?
The certified scope is the manufacture of grey iron and ductile (SG) iron castings, supplied machined and assembled. We also pour steel, which sits outside that certified scope. Single pieces run from 1 kg to 1,500 kg.
Where is the foundry located?
At 127/3B, Sangothipalayam Road, Arasur, Coimbatore, Tamil Nadu 641407, India. The foundry and the machine shop sit on the same 523,200 sq ft site, so buyers in Coimbatore and across Tamil Nadu can audit the whole process in a single visit.
