02 The company
Cast here.
Machined here.
Inspected here.
We are a single-site operation: melting, moulding, sand reclamation, machining, testing and warehousing all sit inside the same 80,000 m² campus. Nothing critical is outsourced, which is why our lead times hold and why a problem can be traced from a shipped carton back to the heat it was poured from.
Tianhe Casting has been pouring iron in Shanxi since 2005. Today the plant runs two imported Danish DISA vertical moulding lines, three domestic vertical lines and a resin-coated sand shell line with a 1,800 × 1,100 × 1,100 mm flask — the combination that lets us run both high-volume pipe fittings and heavier, low-volume OEM castings.

03 Plant
Capacity at a glance
Eighty thousand tonnes a year, split between high-volume fittings and short-run OEM castings — with tooling made in-house so a new part does not wait months for a pattern.

What the numbers buy you
Volume moulding and short-run work share the same melting and lab, so a 500-piece trial gets the same chemistry control as a 50,000-piece repeat order.

04 OEM process
From drawing to container
OEM programmes are the core of what we do. Tooling, sampling and validation are handled by the same team that runs production, so nothing gets lost between departments.
01
Drawing & RFQ review
Send a 2D drawing or 3D model. We come back with a manufacturability review, tolerance callouts and a tooling proposal, usually within two working days.
02
Tooling design & build
Patterns and core boxes are designed and cut in our own tooling shop, so trial dates do not queue behind outside suppliers.
03
T1 samples & report
First-article castings ship with a dimensional report, material certificate and metallographic results for your approval.
04
Process validation
Casting trials on DISA or shell lines, machining fixtures proven, control plan and inspection criteria agreed.
05
Batch production
Repeat orders run on dedicated lines with SPC on critical dimensions; every heat is spectro-tested before pouring.
06
Finish, pack, ship
Machining, coating or galvanising, then export packing with photos and inspection records before dispatch.
05 Quality
Every heat is tested before it is poured
A Swiss ARL spectrometer reads 26 elements in about 30 seconds, so chemistry is corrected at the furnace rather than discovered after machining. Castings then go through metallography, hardness, tensile testing and, where the drawing calls for it, dimensional inspection on a CMM.

Chemistry
ARL optical emission spectrometer, 26 elements, 30 s; CS-9900 carbon–sulphur analyser.

Structure & properties
Zeiss metallographic microscope, hardness tester, SANS electro-hydraulic servo tensile machine.
C
Dimensions & integrity
CMM, gauges and fixtures, plus flaw detection for porosity, shrinkage and cracks.
D
Sand control
Full sand testing laboratory; both sand plants run on-line moisture and compactability control.
06 Export
Where our products go
Piping products and castings ship across Europe, the Middle East, Southeast Asia, South America and Africa. Malleable iron fittings are held in stock by a partner in Brazil, who handles local technical support.
