Your technical third eye in India

Specialist casting sourcing from India

India has a large and capable foundry ecosystem. The challenge for an international buyer is not simply finding a foundry. It is finding the right foundry for the product, the applicable standard and the required production conditions, and then keeping control throughout the manufacturing cycle.

What QX does

India has the foundries. QX finds the right one for your casting.

QX Engineering provides the India-side technical layer. We identify and qualify suitable foundries, support casting development, monitor manufacturing and verify the finished product against the agreed technical requirement.

We do not simply search for a supplier that says, “Yes, we can manufacture it.” We evaluate whether the foundry has the actual technical capability to manufacture it repeatedly.

The test

Eight questions decide the foundry.

Q01
Drawing

What exactly is required?

Q02
Material

What grade, chemistry and mechanical properties are required?

Q03
Process

Can the foundry manufacture the geometry consistently?

Q04
Tooling

Can the pattern and core system produce the required casting?

Q05
Metallurgy

Can the foundry control the melt, treatment and final structure?

Q06
Testing

Can the required testing be performed and documented?

Q07
Production

Can the supplier deliver the required volume consistently?

Q08
Shipment

Can the finished castings be packed, identified and dispatched correctly?

From drawing to dispatch

One technical control system.

Six linked stages keep the requirement, the foundry, development, production, verification and shipment under technical control. Scroll: the colour runs from cold blueprint to hot metal to a released shipment.

Requirement

The path starts with the product, not the supplier.

  • Drawing, specification, material
  • Standard and load class
  • Dimensions and testing
  • Quantity

02

Supplier

The requirement becomes a capability profile; foundries are mapped and audited against it.

  • Foundry mapping, capability review
  • Factory audit, process assessment
  • Capacity assessment

Development

For new castings, technical decisions carry through tooling and first-off trials.

  • Pattern, core, gating, riser
  • Simulation coordination
  • Trial casting and validation

Casting specialisation

We specialise in foundry castings.

QX is built around one manufacturing discipline: casting. Our focus is on ferrous foundry products, particularly ductile iron and grey cast iron.
