Product types – two forms, one process
Both types are produced using the same pure extrusion process – ensuring consistent cross-section quality, dimensional accuracy (±0.1mm), and material integrity. The only difference is the final form: a continuous strip or a closed ring.
| Product Type | Process | Form | Delivery Format |
|---|---|---|---|
| Sealing Strip | Pure extrusion | Strip / profile | Coils or cut-to-length |
| Bonded Gasket (Ring) | Extrusion + automated bonding | Closed ring | Bonded and delivered as finished rings |
Pure extrusion vs. molding – why extrusion wins
| Feature | Extrusion (Yutian) | Molding |
|---|---|---|
| Tooling cost | ✅ Low – simple die | ❌ High – expensive metal molds |
| Length flexibility | ✅ Any length – coils or cut-to-size | ❌ Limited – each size needs a mold |
| Cross-section options | ✅ Any profile – quick die change | ❌ Fixed – each profile needs a mold |
| Lead time for new sizes | ✅ Fast – days, not weeks | ❌ Slow – weeks to months |
| Dimensional precision | ✅ ±0.1mm | ⚠️ ±0.3mm |
| Batch consistency | ✅ Excellent – continuous process | ⚠️ Good – but cycle variations |
| Cost for short runs | ✅ Low – no mold cost | ❌ High – mold amortization |

Customer feedback
“We've been using Yutian's extruded silicone seals for our automotive door seal program for three years. The dimensional accuracy is excellent – ±0.1mm consistently. The extrusion process allowed us to test 12 different profiles without expensive mold costs. Reliable partner.”
— Engineering Manager, European Automotive Supplier
“Yutian provided custom silicone gaskets for our outdoor LED displays. UL94 V-0 flame retardant and UV resistance were critical – 5 years outdoors with no degradation. The factory-direct pricing made our budget work. Highly recommended.”
— Product Manager, US Electronics Manufacturer
Frequently asked questions
What is the difference between sealing strips and bonded gaskets?
Sealing strips are continuous profiles delivered in coils or cut-to-length – ideal for linear applications (door frames, cabinet edges). Bonded gaskets are extruded profiles cut and bonded into closed rings – ideal for circular applications (connectors, housings, enclosures).
Can you custom design a profile for my specific application?
Absolutely. We offer custom profile design – send your drawing or sample, and we'll produce the exact profile you need. Low tooling cost, fast turnaround.
What hardness range is available?
