General FAQ

What industries and parts do you customize?

We focus on three core business areas: agricultural & garden robot components, industrial equipment structural parts, and electric sports device accessories. We provide professional OEM custom metal manufacturing and component assembly solutions. We only produce and assemble functional structural modules and accessory parts, and do not manufacture complete whole equipment or finished machines.

What processing technologies do you support in your own factory?

We have independent in-house production capacity, including CNC precision machining, sheet metal fabrication, and structural component assembly integration. All core metal structure parts and module assemblies are finished and strictly quality-controlled in our own workshop to guarantee stable quality.

Can you provide one-stop hardware and plastic integrated solutions?

Yes. We have a mature and stable supporting supply chain for hardware and plastic parts. We provide one-stop supporting and assembly services for custom structural modules and accessories. Our service only covers component and module matching and assembly, and does not include whole machine production or complete equipment manufacturing.

Do you support prototype and low-volume small batch orders? Any MOQ limit?

We have no strict MOQ limit. We fully support 1-piece prototype verification, 1–500pcs low-volume trial production, and large-batch mass production for custom structural parts and modules. Our flexible production lines perfectly adapt to product iteration, project testing and formal commercial production stages.

Can we modify drawings during small batch production?

Absolutely yes. We fully support iterative design optimization and drawing revision for prototype and small-batch module orders. We record complete production process data for each version, ensuring consistent quality for subsequent product upgrades and repeated orders.

What quality certifications do you have? Can you provide inspection reports?

Our factory is certified with the ISO 9001 quality management system. All products undergo full dimensional inspection before delivery. For assembled structural parts with waterproof and sealing requirements, such as lawn mower motor and electric hydrofoil battery compartments, we conduct professional air tightness testing before shipment to ensure reliable sealing and waterproof performance. We can provide official quality inspection reports, air tightness test records, production records, and related documents for your inspection and factory audit.

What is your standard production lead time?

Prototype orders take 3–7 working days. Small-batch production takes 7–15 working days based on product structure complexity. We arrange dedicated flexible production lines for trial orders to ensure stable and efficient delivery of custom parts and modules.

What are your core advantages compared with other manufacturers?

We integrate in-house core metal processing technologies and mature hardware & plastic supply chain resources. We provide one-stop manufacturing services including drawing optimization, precision production, and structural module assembly. We are specialized in customized parts and module processing only, without involving whole machine manufacturing, helping clients reduce multi-supplier coordination costs and procurement risks.
