ContactQuanzhou Keshiman Kitchen & Bathware Co., Ltd.
Inside Quanzhou Keshiman's 2,000 sqm vertically integrated sanitaryware factory in Nan'an Luncang: in-house mold R&D, gravity brass casting, CNC machining, 6-layer electroplating, and 24h acid salt spray testing.
Quanzhou Keshiman Kitchen & Bathware Co., Ltd. (泉州柯诗曼厨卫有限公司) was established in 2017 with a registered capital of 1,000,000 RMB and Legal Representative Qin Zuoyuan (覃祚远).
Verified via enterprise registration profile; operating in China's core plumbing cluster (Nan'an Luncang / Anxi Yutian Valve Industrial Park, Quanzhou, Fujian).
Operates a 2,000 sqm standardized manufacturing facility staffed by 50+ skilled technicians and production specialists, achieving stable annual sales output exceeding 10 million RMB (10M+ RMB).
Source-factory operational scale supporting both bulk B2B project orders and agile cross-border wholesale replenishment.
Strategically rooted in the Luncang Plumbing & Sanitaryware Industrial Base (Nan'an, Quanzhou) with registered industrial premises at No. 19-3, Yutian Valve Phase II, Chengxiang Town, Anxi County, Quanzhou, Fujian.
Full supply-chain transparency: buyers are welcome to audit both the Luncang supply-chain center and the Yutian Valve Phase II facility prior to contract signing.
Executes 100% closed-loop manufacturing across 5 core stages: (1) In-house mold & tooling R&D, (2) Gravity & low-pressure brass casting, (3) Multi-axis CNC machining, (4) Multi-stage fine polishing, and (5) In-house 6-layer electroplating.
Eliminates trading-company markups and external plating delays while maintaining strict batch-to-batch dimensional tolerance.
Faucet and mixer bodies utilize thickened solid brass one-piece gravity casting to eliminate sand holes, porosity, and internal leakage, paired with low-lead eco-friendly waterway engineering suitable for potable water applications.
Available in CW617N, HPb59-1, DZR brass, and 304 stainless steel grades depending on destination market specification.
In-house electroplating workshop applies a 6-layer thickened plating process validated by 24-hour Acid Salt Spray (ASS) testing to prevent rust, blistering, and peeling in high-humidity coastal and tropical climates.
Available finishes include Mirror Chrome, Gunmetal Grey, Matte Black, Brushed Gold, Rose Gold, and Antique Bronze.
Kitchen mixers and matte/gunmetal shower systems feature a hydrophobic anti-scale nano surface coating that repels hard-water limescale, cooking oil, and fingerprints for single-wipe cleaning.
Reduces hotel housekeeping maintenance time and prevents hard-water mineral crusting in Europe and Middle East installations.
Every assembled faucet, thermostatic mixer, and angle valve undergoes water pressure and pneumatic seal testing (up to 0.80 MPa test bench pressure) prior to export packaging.
Ensures zero-leakage reliability across both low-pressure residential and high-pressure commercial plumbing networks.

Many sanitaryware exporters operate merely as assembly workshops that buy thin-walled zinc or sub-standard brass castings from unverified job shops, resulting in pinhole leaks, thread stripping, and plating blisters after six months in humid bathrooms.
Over the past decade, Quanzhou Keshiman Kitchen & Bathware Co., Ltd. has built a complete, self-contained production chain across 2,000 square meters with 50+ experienced technicians:
1. In-House Mold & Tooling Development: Custom core boxes and die-casting molds engineered directly from buyer 3D STEP/IGES files.
2. Gravity & Low-Pressure Solid Brass Casting: Thickened brass bodies cast with dense grain structure to eliminate internal blowholes and sand porosity.
3. Multi-Axis CNC Precision Machining: Automated CNC turning and milling hold thread pitch (BSPP G1/2", NPT, UNEF) and ceramic cartridge seat flatness to strict industry tolerances.
4. Multi-Stage Robotic & Manual Polishing: Mirror-grade substrate preparation prior to surface treatment.
5. In-House 6-Layer Electroplating & Nano Coating: Copper-nickel-chrome and PVD surface layers validated by 24-hour Acid Salt Spray (ASS) testing, followed by 100% 0.80 MPa hydrostatic water pressure and air-under-water leak testing.
