Yes. You can request a custom clamping knob sample set before bulk production. Zhejiang Dream Industry supports prototype and small-batch CNC orders, drawing-based customization, and standard clamping knob orders with an MOQ that depends on size and specifications. Confirm the design, material, finish, and quantity before sampling; sample lead time is listed as 3–7 days.
A sample request can be based on a technical drawing or project requirements. The product information lists CNC turning, CNC milling, five-axis machining, drilling, tapping, grinding, and other processes. Available material groups include stainless steel, carbon and alloy steel, aluminum, brass and copper, and engineering plastics; the final selection depends on the part specification.
Before production, confirm the knob dimensions, material, surface treatment, color, and any custom logo or packaging requirements. The company supports drawing confirmation and prototype development. Its stated sample lead time is 3–7 days, while the product listing gives a general lead time of 7–25 days; timing for a specific sample set should be confirmed against the design and order details.
The company lists ISO 9001 certification and inspection services including first article and full-dimensional inspection. One reported project supplied adjustable clamping knobs for CNC machines to a customer in Italy, for positioning and fixture-locking systems. The company reported a 65,000-piece project quantity; this case does not establish the sample quantity or specifications for a new order.

| Order type | Listed quantity guidance | Use |
|---|---|---|
| CNC prototype or sample order | 1–10 pieces | Check fit, function, or design before production |
| Standard clamping knobs | MOQ 10 pieces, depending on size and specifications | Order standard products or assess a standard configuration |
| Custom OEM product | MOQ 200–1,000 pieces, depending on complexity and tooling | Custom dimensions, materials, or other non-standard requirements |
| Small-batch CNC machining | 50–500 pieces | Trial or limited production run |
Can I order samples before committing to bulk production?
Yes. Prototype and sample orders are supported for CNC precision machined parts, and small-batch trial production is available. Confirm whether the specific clamping knob design is treated as a CNC sample or a custom OEM product.
What files should I provide for a custom sample?
PDF, CAD, DWG, DXF, STEP, IGS, and STP technical files are listed as supported. Include the required dimensions and relevant material or surface-treatment details for confirmation.
How long does sampling take?
The stated sample lead time is 3–7 days. The product listing separately gives a general lead time of 7–25 days, so confirm the schedule for the requested design and quantity.
A custom clamping knob sample set can be requested before bulk production. Send the drawing and specify material, finish, dimensions, and sample quantity so the applicable MOQ and lead time can be confirmed. The company supports OEM and ODM manufacturing, custom CNC machining, factory-direct supply, and flexible small-batch orders; its manufacturing system is ISO 9001 certified.
