Our Factory
A real factory in the Greater Bay Area.
Not a trading desk with borrowed photos. We own our injection moulding line and mould room, and we run a vetted partner network for ceramics and brass — all to one QC standard.
Why we exist
We started TRILINE to kill the middleman tax.
Most Western brands buying from China are quietly paying a trading company 10–40% on top of the real factory price — for a product made in a workshop they will never see. We think that is broken.
So we built the opposite: a founder-run factory where the factory price is your price, where the tooling is ours and stays yours, and where you can verify everything — the licence, the audits, a live walkthrough — before you wire a cent.
One manufacturing backbone, injection moulding, lets us go deep across three lines: plastics, toys and bathroom. One mould, three lines.
Inside the factory
The proof, workshop by workshop
Injection moulding hall
In-house presses from 80T–650T running plastics, toys and bath components.
In-house mould room
CNC, EDM and tooling bench — we build and own the moulds, so samples are fast.
Quality control lab
Gauges, CMM and salt-spray testing. Every batch checked at AQL 2.5.
Finishing & assembly
Polishing, PVD-finish partners, assembly and leakage testing under one roof.
Warehouse & consolidation
Free in-house storage, multi-supplier consolidation and FBA prep.
Packaging line
Custom retail boxes, branded inserts, barcoding and poly-bagging.

The honest model
We own one line, and we're transparent about the rest.
We will never pretend one factory makes everything. Here's exactly how it works:
Our captive injection line
Plastics, plastic toys and bath components are made on our own floor — full control of tooling, QC and lead time.
Audited partner factories
Ceramics, brass faucets and specialist work go to vetted partners in Chaozhou, Kaiping and Foshan — same QC and audit standards, pass-through pricing.
One accountable partner
You deal with us for the whole line — design, production, QC, packaging, freight — under a single point of accountability.
Audited & certified
Factory-level and product-level — every certificate number is independently verifiable.

Equipment & capability
What's on the floor
A trader can't show you this. Here's the machinery that makes us a real factory.
Injection presses
40+ machines, 80T–650T — small precision parts to large housings.
Mould-making shop
CNC machining, EDM and wire-cut — we cut our own steel.
Brass casting & CNC
Gravity casting and multi-axis CNC for faucet bodies.
Finishing line
Robotic polishing and PVD-finish partners for matte black & gold.
QC lab
CMM, projection system, gauges and salt-spray testing.
Assembly & packaging
Multiple assembly lines, leak testing, and an in-house packaging line.
Our story
From a mould shop to a full-line factory
Started as a mould shop
Cutting tooling for the plastics and toy industries — tooling has been our craft from day one.
Added injection moulding
Brought production in-house so clients could go from design to finished part under one roof.
Three lines, one backbone
Extended the same injection-moulding capability across plastics, toys and bathroom — and built the audited partner network for ceramics and brass.
Factory-direct, founder-run
A full-service partner — design, production, packaging, shipping and dropshipping — for brands that want the factory, not the middleman.
