Kingmax Outdoor (永康市青沐户外工贸有限公司) operates a vertically integrated 40,000 m² manufacturing campus in Yongkang, Zhejiang. The facility houses four specialised workshops — metalwork, assembly, wood/bamboo, and QC — producing 300,000+ units monthly across folding chairs, tables, cots, shelves, and wagons. Capabilities span from rapid prototyping (7-day samples) through mass production, with ISO 9001 / 14001 / FSC / BSCI certified quality systems. This guide details each production department and the end-to-end OEM/ODM process.
The metalwork shop houses a 60-person team operating automatic laser cutters, CNC tube benders, precision welding stations, and anodising lines. It processes 7075 and 6061 aluminium alloy tubing, carbon steel tube, and stainless steel sheet. Monthly throughput exceeds 150 tonnes of processed metal. All aluminium cutting produces burr-free edges; welding uses TIG (tungsten inert gas) for aluminium and MIG for steel. In-house anodising eliminates the 5-7 day delay of outsourced surface treatment.
Assembly operates across 12 production lines staffed by 160+ skilled workers using 180 assembly machines. Each line is configured for a product category (chairs, tables, cots). Kingmax uses a four-stage QC system: first-piece inspection (before production run), 2-hour patrol inspection (during production), 100% final inspection (every finished unit), and AQL 1.5 outbound sampling (before container loading). The in-house lab conducts load testing, cycle testing (10,000+ open-close cycles), salt spray corrosion testing (500+ hours), and UV fade testing.
The wood/bamboo workshop processes FSC-certified walnut, beechwood, oak, and bamboo for Kermit chairs, table surfaces, and premium accessories. Equipment includes CNC routers, drum sanders, and spray lacquer booths with dust extraction. All timber enters with FSC chain-of-custody documentation, maintaining certification through to finished goods. Monthly wood processing capacity is approximately 20,000 units. Custom wood stain colours and finish textures are available from 500 pieces.
Kingmax's standard OEM/ODM process: Day 1-2 — receive brief, return quotation with BOM. Day 3-10 — sample production (7 business days standard, 3 days rush). Day 11-15 — sample review, revision if needed. Day 16-20 — order confirmation, 30% deposit, tooling/mould if required. Day 21-55 — mass production (30-35 days). Day 56-58 — final QC, container loading, shipping documents. Total lead time from brief to port: approximately 8 weeks for standard products, 10-12 weeks if new moulds are required.
