Twenty years of silicone, one plant, no middlemen.
Dongguan Yutian Silicone Rubber Technology Co., Ltd. has been compounding and extruding silicone since the early 2000s. Today 38 extrusion lines, an in-house tooling shop and a 500+ customer base across 30+ countries run from one industrial park in Dongguan — which is why your drawing reaches the person who sets the machine.

A silicone factory that answers
its own emails
We started as a small extrusion workshop supplying local manufacturers. Two decades later the same team still runs production — the difference is that the workshop became a plant with its own compound lab, tooling shop and inspection room.
We are not a trading company with a catalogue of other people’s factories. Every metre of tubing, every profile and every gasket shipped from Dongguan is made by people we employ, on machines we maintain, against drawings we have read ourselves.
In-house compounding
Hardness, colour and conductivity formulated on site
±0.05 mm tolerance
Measured on every production run, not sampled from the end
7–10 day tooling
Dies cut and polished in our own tool room
100% inspection
Final AQL check before cartons are sealed
Six capabilities, one supplier
Most projects need more than tubing. Because compounding, extrusion, moulding and packing all sit in the same plant, a mixed order ships as one consignment — and one team owns the tolerance.
Compound development
Platinum-cured, peroxide-cured, FDA and LFGB compounds formulated in our own lab — including custom colour matching and hardness from 20 to 80 Shore A.
Precision extrusion
Tubing from 0.5 to 50 mm OD, profiles down to ±0.05 mm, plus multi-lumen and co-extruded sections on 38 lines.
Compression & LSR moulding
Gaskets, O-rings, diaphragms and over-moulded parts from 500 pcs, with flash-free finishing.
Calendering & slicing
Sheet from 0.5 to 10 mm, slit to width or cut to panels, with or without fabric reinforcement.
Inspection & documentation
Dimensional reports, material certificates, PPAP and batch traceability issued with every shipment.
Assembly & packing
Cutting, bonding, printing, bagging and kitting — packed to your retail or line-side requirements.
Four gates before
anything ships
Quality is not a final inspection. Each batch passes four checks, and the records travel with the cartons.
Incoming material
Every compound batch is checked for hardness, specific gravity and cure rate before it reaches a line.
In-process
First-off approval, then dimensional checks every 30 minutes with records kept per machine.
Final inspection
AQL sampling on dimensions, appearance and elongation before packing.
Documentation
Material certificate, dimensional report and batch number issued with the packing list.
What changes when you buy from the plant
Both can send you a quotation. Only one of them can change a die, adjust a compound or explain why your tolerance is drifting.
You talk to the people who make it
Quotation prepared by the engineer who will run your job
Tooling made and maintained in our own shop — 7–10 days
Compound changed in-house when a test fails, not outsourced
Tolerance and lead time confirmed against real machine capacity
One batch record for every shipment, traceable to the line
You talk to a mailbox
Quote passed between three parties before it reaches a factory
Tooling subcontracted, schedule depends on someone else’s queue
Material issues take days to diagnose and longer to fix
Lead times padded to protect the middleman
Paperwork assembled after the fact, often incomplete
Nothing here is subcontracted
Extrusion, moulding, post-curing and packing are all on the same site. If a run needs a die polished or a compound adjusted, it happens in the building — not in a truck going to another supplier.
Come and see the plant —
or send us a drawing first.
Factory visits are welcome Monday to Saturday. If you are not travelling yet, a drawing and a target price are enough to start.
