  Supply custom metal parts service for sand casting turbine housing

OEM ductile-iron sand casting supports agricultural-machinery and tractor-component enquiries from customer drawings. Grade options include GGG40, GGG50 and GGG60, with complete standard and material condition selected for the actual design. Separately specified cast-iron pulley or turbine-housing work requires its own component definition.

Identify the actual equipment connection

Show the tractor, pulley or housing interfaces relevant to the ordered part. Describe the working loads and operating conditions that govern its evaluation. Mark mounting and locating relationships so a heavy-duty request becomes a defined geometry and acceptance requirement rather than an assumed load rating.

Keep casting and machining criteria separate

CT9–CT11 is a casting-tolerance reference for cast-iron pulley work; agree its applicability to the selected order. Machining references are up to IT7 and Ra0.8–3.2, with convention, roughness unit and assessment stage to define. Available operations include CNC machining, drilling, milling, boring and tapping.

Choose the surface package for the part

Dacromat coating and finish painting are offered treatments. Identify treated areas and their required result for the chosen substrate. Define functional contacts separately from visible surfaces, including the condition in which their final dimensions are accepted.

• Provide the controlled drawing revision and complete iron specification.
• State quantity, actual assembly duty and initial approval requirements.
• Specify inspection coverage and the material or dimensional records needed.

Packing uses a multilayer wooden box with a large inner plastic bag. Record approved changes to geometry, material and finishing within the selected component’s work package for subsequent manufacturing requests.
