What is the MOQ?
We typically don't set minimum order quantities, though larger quantities receive better pricing. We're happy to produce prototype parts or samples to ensure quality standards.
Can you provide samples?
Yes, sample costs are required, but we refund these costs when proceeding to mass production. If tooling is needed, we charge mold fees before starting production.
What's your products range?
Our OEM & ODM products range includes: Auto parts, Truck Parts, Engine parts, Agriculture equipment parts, Train parts, Hardware, and various industrial components.
What machining machines do you have?
We operate CNC punch presses, laser cutting machines, CNC bending machines, and other advanced fabrication equipment.
Do you have any test equipment?
Yes, we have Optical Spectrum Analyzer, CMM, Hardness test equipment, and Tensile test machines for comprehensive quality verification.
How do you handle poor quality products?
All our products undergo QC inspection with reports before delivery. In the rare case of non-conformance, please contact us immediately with pictures/videos or return defective products for replacement.
