Our ServiceCustom make Sand Casting Products as per drawings or samples
Iron castings made from a drawing or sample need the blank and the finished part considered separately. This custom sand-casting service covers ductile and grey iron components with machining and requested surface finishing. Begin the enquiry with the material designation and the surfaces that determine the component's completed condition.
Keep the ductile-iron designation explicit
QT450, GGG40, GGG50 and GGG60 are material enquiry designations for the ductile-iron offering. Identify the grade and applicable standard required for the individual part rather than treating these names as automatic equivalents. A grey-iron component should likewise retain its own material specification when the drawing or sample is submitted for the casting discussion.
Separate blank tolerance from final machining
Sand-cast blanks carry a CT9-11 tolerance reference. Machining capability is stated up to IT7 according to customer requirements, with surface roughness to be agreed for the particular surfaces and units on the drawing. This distinction allows the iron enquiry to describe what is needed from the casting stage and what belongs to the completed machined component.
- CNC machining supports the finished iron-part requirement.
- Lathing and turning are available for the selected component geometry.
- Milling, boring and drilling are additional operation choices.
- Painting and Dacromet coating are requested finish options.
- Packaging uses a multilayer wooden box with an inner plastic bag.
Build the order around the drawing or sample
Provide the intended quantity, material requirement and acceptance dimensions when requesting the custom iron part. If a sample defines the starting geometry, identify the finished surfaces and requirements that the new component must satisfy. The useful manufacturing brief for this foundry service connects the chosen iron grade, cast blank, machining work and final surface condition without assuming every part needs the same operations.
