MOQ50-100pcs
OEM custom cast-iron parts combine sand casting with precision-machining and heat-treatment requests. The minimum-order reference is 50–100 pieces. Select the complete grade and drawing for the component, including the material condition and manufacturing stage required at acceptance.
Define large-part geometry and key dimensions
Size enquiries include 120 cm or larger, with the actual envelope and capability to agree from the drawing. Key-size tolerance is referenced as 0.01–0.02 mm. Identify the affected dimensions, convention, datums and supplied stage used to assess the selected component’s fit.
Keep QC coverage aligned with the drawing
Random checks during production are combined with 100% checks of key sizes. Mark those dimensions and define measurement methods and reporting. Identify material and surface evidence needed alongside dimensional records, including the checks required after any selected treatment or machining.
- Choose painting, powder coating or a customer-requested finish.
- Define color by drawing, sample or a specified Panton reference.
- Supply 2D PDF/CAD or 3D IGES/STEP information.
- Packing combines bubble bag, carton and wooden crate.
Set the approval result and protected supplied state
Provide quantity, the controlled revision and protection requirements for finished interfaces. Identify the protected working surfaces when specifying the final packing arrangement. Explain what an initial part must demonstrate about geometry or appearance. Retain approved material, key-size and finish changes with the component definition so the order’s acceptance follows the actual casting and precision-machined result.
