Inventor & General Manager: Feng Jian (冯健)
This profile is one of four CNIPA design patents granted to Dezhou Jiasheng Rubber And Plastic Products Co., Ltd. in 2019. Mr. Feng is named as the sole designer on all four patent certificates.
Overview
For the most demanding heavy-load conveying — bulk material on triple-strand chains, large carrier platforms, parallel drive systems — the T3 patented profile integrates three precision chain pockets on a single wide UHMWPE base.
Design Principle
T3 extends the T2 concept to three pockets, with a wider base (60-90 mm typical) and reinforced shoulder geometry to handle the increased lateral loads of triple-chain systems. The three pockets are machined in one setup, holding inter-chain parallelism within ±0.15 mm over 6 m.

Real-World Applications
Heavy steel coil transfer
Triple-chain transfer cars in steel mills use T3 to spread coil weight across three load paths.
Glass furnace exit conveyors
Three-strand chain conveyors at glass tempering lines benefit from T3's heat resistance and parallel chain accuracy.
Large-format panel handling
Wood, MDF and gypsum board transfer lines with 1.2-2.4 m wide panels use T3 for stable triple-chain support.
Mining and bulk material
Triple-chain apron feeders and bulk drag conveyors use T3-based wear rails to extend chain life under abrasive loads.
Automotive body-in-white
Heavy car-body carrier lines on triple chain use T3 for silent, lubrication-free operation in paint shops where oil contamination is forbidden.
Why a Patented UHMWPE Profile vs Alternatives
| Solution | Engineering Performance Summary |
|---|---|
| UHMWPE patented profile (our solution) | Self-lubricating · 0.10-0.15 friction · Silent · 25,000-40,000 hr life · No grease · -50 to +80 °C |
| Generic UHMWPE flat strip | No chain pocket, requires external chain guides → assembly complexity, alignment errors |
| Steel side rails (greased) | Requires daily / weekly lubrication · 0.20-0.30 friction · Noisy · 5,000-8,000 hr life · Oil contamination · Energy +10 % |
| Stainless-steel side rails | 5-10× cost · Same friction issues · Heavier · Used only when hygiene mandates exclude polymer (rare) |
| PA6 cast nylon profile | Higher temperature (+120 °C) but absorbs moisture (swells), 2× friction of UHMWPE, shorter wear life |
| Phenolic / paper laminate | Brittle under impact, cannot absorb chain slap, obsolete technology in modern conveyor design |
Material — Verified 8.62 Million Mw UHMWPE
All patented profiles are machined from our in-house UHMWPE compound with verified molecular weight of 8.62 × 10⁶ Da (CTIC report no. CTICAAD39240944050802BR, ISO 1628-3 method). This molecular weight is at the high end of commercial UHMWPE grades and delivers the abrasion resistance, impact strength and low coefficient of friction that the patented geometry was designed to exploit.
- Tensile strength 32.8 MPa (SGS report TJIN2007009852MR_CN)
- Elongation at break 240 %
- Coefficient of friction (dry) 0.10 – 0.15
- Compressive yield ~ 22 MPa
- Service temperature -50 °C to +80 °C continuous
- FDA compliance 21 CFR 177.1520 (CTB220513031CX)
- RoHS 2011/65/EU 26-substance scan, all below detection (SCT-20141027-036N)
Frequently Asked Engineering Questions
What chain centres are standard for T3?
40 / 60 / 80 mm typical. Custom centres CNC-machined to your DWG.
What chain pitches does T3 support?
T3 is stocked for 06B-3, 08B-3, 10B-3, 12B-3, 16B-3, 20B-3, 24B-3 triplex chains.
How much load can a T3 profile carry?
Static load capacity depends on UHMWPE compressive yield (~22 MPa). For a 90 mm wide T3 with 6 m length supporting three chains, distributed load capacity exceeds 8000 kg. Detailed engineering calculation provided on request.
Can T3 be supplied in stainless-steel reinforced form?
For extreme loads or impact applications, we machine T3 profiles with embedded stainless 304 reinforcement bars in the base. Lead time 30-40 days.
Patent reference?
CNIPA design patent ZL 2019 3 0404445.X, certificate no. 5552326, inventor Feng Jian (冯健), granted 2019, valid through 2029.
Is T3 available in food-grade UHMWPE?
Yes, but most T3 deployments are in heavy-industrial applications where food grade is not required. Specify in your quote if needed.
What overall heights for T3?
20 / 25 / 30 / 35 / 40 mm standard.
How are T3 profiles mounted?
Standard pattern is M10 or M12 bolts on 200-300 mm centres along the base. We CNC-drill and counterbore at our factory based on your DWG.
Lead time and MOQ?
7-15 days for stock profiles · 20-30 days for custom CNC. 1 piece for stock SKUs · 50 pieces for custom CNC.
What freight options are available?
Sea freight FOB Qingdao (most economical for >100 m of profile), or air freight for urgent prototypes. We also handle DDP terms to EU and US destinations on request.
