Our ServiceSupply large resin sand ductile iron casting
Custom large resin-sand ductile-iron enquiries include GGG70, GGG40 or FCD500 grade requests with CNC machining and sandblasting. Identify the full material designation and governing standard for the component. The actual drawing should define the envelope, functional interfaces and condition required at delivery.
Establish the large casting’s dimensional scope
The resin-sand blank has a CT9–CT11 casting-tolerance reference. Assign the relevant dimensions and checking arrangement for that stage. Show the mounting and mating geometry in relation to the overall form, and agree actual capability for the selected large component.
Define the operations after casting
Named machining includes CNC work, drilling, milling, boring and tapping. For the finished areas, define the dimensions and surface checks against the up-to-IT7 and Ra 0.8–3.2 references. Specify the roughness unit, datum scheme and supplied stage used for acceptance. Include any measurement-access requirements for the large part in the approval plan.
- Give quantity and the controlled drawing revision.
- Identify cast and finished surfaces.
- State the material condition and inspection records required.
- Define sample or first-part approval for the actual geometry.
Coordinate treatment and packing protection
Dacromat coating and finish painting are additional finish choices. Mark masking boundaries and the required appearance at functional areas. Packing is a multilayer wooden box with a large inner plastic bag; include separation and protection for the delivered interfaces. Confirm the production scope and schedule using the selected drawing, grade and treatment requirements.
