Five Pillars of WECOME
From raw materials to finished equipment, every pillar is built on quality control, industry experience, and a commitment to long-term partnership.
WECOME: Your All-in-One RO Membrane Supply Partner
Headquartered in Shanghai, WECOME was established to solve a real problem in the RO membrane industry: manufacturers had to coordinate with dozens of suppliers for just one membrane element — tapes, spacers, carriers, seals, adhesives, and machines all from different sources.
We changed that. By building a vertically integrated supply chain and maintaining direct partnerships with factories in Zhejiang and Henan provinces, WECOME delivers every core material and the equipment to process it — from a single point of contact.

Controlled. Scalable. Transparent.
WECOME's manufacturing footprint spans three strategically located provinces in China — giving us both geographic resilience and logistics efficiency. Each facility is purpose-built for membrane material production and operates under strict internal quality protocols.
Our clients are welcome to visit our factories. We believe seeing is believing — and that's why we publish factory documentation and invite partners to audit our production lines in person.

Every Batch. Every Specification. Verified.
Quality control at WECOME isn't a department — it's a process that runs from incoming raw materials to the final outbound inspection. We use standardized test protocols for thickness, tensile strength, adhesion, durometer hardness, and dimensional accuracy on every product category.
SGS test reports for selected RO membrane components are available on request, supporting downstream compliance review and supplier qualification.

Export-Ready. Globally Connected.
WECOME has built a robust export operation serving membrane manufacturers and water treatment companies in 30+ countries. Our export team handles documentation, customs clearance coordination, and freight logistics — so you receive your order complete and on time.
We support FOB, CIF, and DDP terms and work with established freight forwarders for sea and air shipments. Our export experience spans Southeast Asia, the Middle East, Europe, North America, and South America.

Your Brand. Our Materials. Built Together.
WECOME's OEM and custom manufacturing service lets membrane brands source high-quality components under their own brand identity — without the capital investment of building their own factory. We support color-matched formulations, custom dimension rolls, branded packaging, and anti-counterfeit labeling.
Whether you need a specific color for your brine seal, a non-standard width for your outer wrap tape, or custom barcodes for your component boxes, our technical team will work with your specs from prototype to mass production.
