WHAT WE DO
From inquiry to validated sealing solution.
Our service is built around the real sealing problem: lid groove geometry, filled media, compression, production method and long-term storage conditions.
Material selection
Compare economy EVA, high-density EVA, high-elastic / food-grade EVA, solvent-resistant EVA, NR, EPDM, silicone, PVC and PU options.
Sample and prototype
Prepare ring, strip, compound or accessory samples for dimensional check, compression fit and compatibility evaluation.
Process validation
Support strip lining, PVC oven-curing FIP and two-component PU dispensing trials, including bead path, curing and overlap review.
Equipment matching
Match EVA automatic gasket lining machines, PVC single-component dispensing machines and PU two-component dispensing machines to the selected material.
Production support
Help troubleshoot leakage, rebound, bead weight, joint strength, curing, storage and batch consistency during scale-up.
SERVICE SCOPE
Support matched to each product family.
Each category has a different approval path. We organize the service around the product system customers are actually buying.
| Product system | Service focus | Typical output |
|---|---|---|
| EVA rings / liners | Supply form, grade selection, cross-section, compression and chemical fit. | Sample ring, grade recommendation, TDS and quotation. |
| EVA roll stock | Width, thickness, roll length, core ID and automatic lining compatibility. | Roll specification and machine feeding recommendation. |
| NR / EPDM / silicone | Temperature, weather resistance, rebound and media compatibility. | Material comparison and custom shape / size proposal. |
| PVC / PU FIP | Dispensing path, bead size, curing or reaction process and machine settings. | Compound data, trial guidance and equipment configuration. |
| Packaging accessories | Handle, welding ear, welding piece, cap and closure selection by drawing. | Accessory SKU confirmation and sample matching. |
