OEM / Custom Manufacturing Process
As a flexible belt pulley supplier, NDS supports both standard catalog orders and OEM custom drawing-based orders. Use our V-belt pulley selector to confirm your designation, groove count and bore diameter before sending the inquiry. Our custom order workflow:
- Inquiry — submit your drawing, spec sheet, or sample
- Quotation — receive a detailed quote based on drawing complexity and order scope
- Drawing Review — our engineers confirm feasibility and propose DFM improvements
- Production — pattern making → casting → machining → surface treatment → QC
- Inspection & Delivery — pre-shipment inspection, packing, and tracking
MOQ: depends on the pulley model, material, machining requirements and customization level.
Lead Time: confirmed according to product specification, quantity and production requirements.
Payment Terms: confirmed with the quotation and order.
Frequently Asked Questions
What is your MOQ for custom belt pulleys?
MOQ depends on the pulley model, material, machining requirements and customization level. Mixed models within one container are often acceptable; please contact us to confirm.
Do you provide material certificates?
Yes. We provide mill test certificates (MTC) for all metal materials and dimensional inspection reports for each production batch.
What is the typical lead time?
Lead time is confirmed according to product specification, quantity and production requirements. Standard catalog orders are typically faster than custom drawing-based orders.
Can you manufacture to my drawing?
Yes. We accept DWG, DXF, STEP, IGES, and PDF drawings. Our engineers will review your drawing for manufacturability and provide DFM suggestions if needed.
What surface treatments are available?
We offer phosphating, zinc plating, black oxide, electrophoresis, and powder coating. For marine applications, salt-spray-resistant treatments are available.
Do you offer warranty?
Warranty terms vary by product and order; the applicable warranty statement is provided with the quotation.
