Built for What Lies Beneath
Composite underground enclosures and complete FTTH components — molded, tested and packed under one roof.
Two product lines, one supply base
Jiangsu Fuzhuo Intelligent Technology Co., Ltd. (FZ Tech) manufactures composite underground enclosures and complete FTTH components for telecom carriers, ISPs, utilities and contractors.
Founded in 2021 in Yancheng, Jiangsu Province, we operate a 40,000 m² production base where the material, the mould and the finished part all come from the same plant. Every manhole, handhole and cover is molded in a single high-temperature shot — no welding, no seams, no corrosion path. The same site also builds the cables, closures and terminal boxes that complete the route, so a network builder can source the whole outside plant from one supplier and one shipment.
Four production disciplines, under one roof
Rare among composite enclosure suppliers, our plant combines moulded composite, precision plastic, sheet metal and in-house tooling. That is what lets us quote a complete, ready-to-install product instead of a part that somebody else has to finish.
SMC & BMC compression molding
The core of the plant. Large presses mold fiber-reinforced sheet and bulk compound into manhole bodies, handholes and covers — high-temperature, single-shot, no welded seams.
Injection molding
Dedicated injection machines run the precision plastic parts: terminal-box and enclosure bodies, adapter plates, trays and small components that must hold tight tolerances.
Sheet metal fabrication
Cutting, punching and bending lines produce brackets, mounting frames, internal supports and metal accessories — so hardware arrives with the product, not from a third party.
In-house tooling & mould shop
Mould design, machining and maintenance sit on site. New tooling, custom pigments, molded-in logos and cable-port knockouts are developed and proven without outsourcing.
From raw material to loaded container
Compounding, moulding, machining, assembly and packing all happen on the same floor — which keeps lead times short and quality traceable end to end.

We test it before you do
Moulded composites only earn their reputation through consistency, so we run our own materials laboratory. Raw compound is checked on arrival, molded parts are verified in process, and finished goods are tested before they are packed. That data is what backs the load ratings and material properties we quote — not a brochure figure.
Mechanical & hardness testing
Digital Shore durometer and hardness benches confirm the material has cured to spec, batch after batch.
Electrical & insulation testing
Insulation resistance instruments verify the non-conductive, no-grounding property that keeps composite enclosures safe.
Wear & durability testing
Abrasion and rub-wear testers check the surface and coating performance that decides service life underground.
Load & dimensional control
Cover load ratings and hard dimensions are checked against the drawing before any set leaves the plant.
