What Gets Checked, and What You Get in Writing
A casting is only as good as the evidence that travels with it. This page sets out the inspection points on a DINGDAR order, the records released with the shipment, and the scope we do not claim without checking first.
Five Stages, Five Records
Each stage produces a document. The scope is fixed in the technical review before production, not negotiated after the parts are cast.
| Stage | What is checked | Record released |
|---|---|---|
| Before pouring | Pattern and drawing review, material grade confirmed against the duty, melting charge checked | Approved drawing / part number, grade confirmation in the technical review |
| At pour | Melt chemistry — manganese, chromium and carbon content against the specified grade | Chemical composition report per heat |
| After heat treatment | Hardness verification on the working section | Hardness results with test location noted |
| Before despatch | Dimensional check against drawing, visual inspection of working faces, casting defects | Dimensional report; visual inspection record |
| On request | Ultrasonic or magnetic-particle testing on heavy-section parts; third-party inspection | NDT report or third-party certificate, scope agreed before production |
The Record Is the Argument
Wear part failures are usually argued after the fact, and the argument is almost never settled by opinion. A plate that cracked through a bolt hole, a liner that wore through in half the expected hours, a blow bar that chipped on the first day — each has a small set of possible causes, and the paperwork narrows them quickly. Chemistry tells you whether the grade poured matches the grade ordered. Hardness tells you whether the heat treatment landed. Dimensions tell you whether the part seated correctly. Without those three, every conversation about a failure starts from zero.
That is why the inspection scope is agreed at quotation stage. A buyer who specifies the evidence before production receives it with the shipment; a buyer who asks afterwards is asking a foundry to reconstruct a heat that has already been poured.
What We Do Not Claim
Certification lists published on websites go stale, and a stale certificate is worse than no certificate — it wastes a buyer's audit. We do not publish a badge wall. If your market or your customer requires a specific certificate, tell us the standard and the part, and the current scope for that combination is confirmed in writing with the quotation.
The same applies to capacity and lead-time claims: both are confirmed per project after the drawing and quantity are known, because a number that is right for a 200 kg mantle is wrong for a 4-tonne mill head.
