ABOUT FLOWVEINS
An Innovator, Not Just an OEM Factory.
FlowVeins is the exterior cladding brand of MexyTech — a Foshan WPC manufacturer since 2009, and the first in South China to master Molecular Crystallization Bonding Technology. Where most WPC factories stop at OEM orders, we engineer our own brands and ODM systems: FlowVeins for cladding, ZipDeck for decking.

WHO WE ARE
A Technology Brand, Not Just an OEM Factory.
MexyTech has manufactured WPC building materials in Foshan since 2009 — and was the first factory in South China to master Molecular Crystallization Bonding Technology, the process that fuses the texture into the ASA surface instead of printing it on.
That technical edge shapes how we work. Unlike WPC factories that only run OEM orders, we build our own brands — FlowVeins for exterior cladding, ZipDeck for decking — and take on ODM programs where we engineer the product, not just produce it.
The same mindset has produced easy-install systems, upgradable base systems, and easy-install interlocking decking for our clients. FlowVeins carries that standard into wall cladding.
MILESTONES
From a WPC Line to a Cladding Brand.
Key steps in how MexyTech grew from a composite manufacturer into the team behind FlowVeins.

Incorporation of MexyTech
The company is incorporated in Foshan. One WPC line, one export market, and a decision to extrude in-house rather than buy the process in. That choice still decides how every batch is made.

R&D cooperation with South China University of Technology
Joint development for material formulation and production control, led with Dr. Michael and his 20 years of R&D experience. In-house testing becomes part of the process, not an afterthought.

Capacity expansion to 20 production lines
Output scales to 20 extrusion lines, letting larger project volumes be scheduled rather than queued behind stock orders.

Suprotect — second-generation WPC
A co-extruded protective shell wrapped around the core. Suprotect set the durability baseline every MexyTech line since has been measured against.

60 extrusion lines, 30,000 m² of plant
Production grows to 60 in-house extrusion lines across more than 30,000 m² of facility.

Third-generation WPC
Deeper embossed grain over a tougher co-extruded surface — the material step that made the FlowVeins texture possible.

FlowVeins launches
A dedicated exterior wall cladding line: fourth-generation WPC core, composite ASA surface, and Molecular Crystallization Bonding. Built for facades, not adapted from decking.
WHAT WE DO IN-HOUSE
Capability You Can Verify.
The work that decides cladding quality happens inside our facility. Here is what we control directly, end to end.
In-House Extrusion
Fourth-generation WPC cores are extruded on our own lines, so core density, toughness, and dimensional stability stay consistent from batch to batch.
Surface Engineering
The composite ASA surface and FlowVeins brushed texture are bonded through Molecular Crystallization Bonding — texture fused in, not printed on.
Quality Control
Performance is verified by third-party SGS testing — UV aging, water absorption, flexural strength, and fire classification — not just internal checks.
Customization
OEM programs, custom colors, and non-standard lengths are supported for project and distributor orders beyond the two standard profiles.
Export & Logistics
Years of container-load export to international markets, with documentation and packing built for long-haul project delivery.
Technical Support
Installation guidance — joist spacing, clip systems, predrilling — and specification support for facade contractors and project teams.
