SEALING, CUSHIONING & VIBRATION ISOLATION
Custom Die-Cut Foam Gaskets & Pads
Precision converting of microcellular foams, elastomeric sponges, and closed-cell rubbers. We engineer custom kiss-cut gaskets, sealing rings, and shock-absorbing pads with optional custom pressure-sensitive adhesive backing (3M™, Crown, Nitto) tailored for electronics, automotive, and industrial enclosures.

CLOSED-CELL & COST EFFECTIVE
EVA, Polyethylene (PE) & 3M 1600T
Cross-linked closed-cell foams offering impermeable moisture barriers, high structural resilience, and cost-effective dimensional spacing. Available in high-density formulations and standard adhesive PE foam rolls like 3M™ 1600T.
- Foam Types: High-density EVA (38°–70°), Cross-linked PE (XPE/IXPE), 3M 1600T PE double-coated tape

- Applications: Appliance foot pads, industrial spacers, automotive mirror/trim mounts
EXTREME TEMPERATURE & FLAME RETARDANT
Silicone Foam & Thin Rubber
Engineered for extreme operating temperatures (-60°C to +200°C) and harsh UV/ozone environments. Available as microcellular silicone sponge (Rogers BISCO® equivalent) or ultra-thin solid silicone membrane sheets.
- Thermal Resistance: Continuous performance from -60°C to +200°C
- Safety Rating: UL94 V-0 flame rating options, non-toxic & food/medical compliance
- Applications: EV battery pack enclosure seals, outdoor telecommunication cabinets, LED lighting gaskets
OUTDOOR WEATHER & AUTOMOTIVE SEALING
CR Neoprene
Resilient closed-cell synthetic rubbers built to withstand oil, weathering, ozone exposure, and mechanical abrasion. Ideal for automotive door/lamp sealing and external industrial machinery enclosures.
- Resilience: Superb resistance to aging, sunlight, grease, and moisture
- Material Grades: 100% CR (Chloroprene Rubber), blended CR/SBR, EPDM sponge
- Applications: Automotive HVAC seals, door weatherstripping, marine waterproofing gaskets
Custom Adhesive Lamination on Raw Foams
Many engineering foams and rubbers are produced without self-adhesive backing. Through our in-house multi-station laminating equipment, we pre-laminate premium pressure-sensitive adhesives (PSA) onto any foam substrate before single-pass die-cutting.
3M™ PSA Systems
Lamination with 3M 9448A, 467MP, 468MP, or 300LSE for high adhesion to low surface energy plastics.
Crown / Cost-Effective PSA
High-performance Crown (皇冠) tissue & PET double-sided tapes delivering high holding power at economical unit costs.
Differential & Supported
PET film-supported adhesives prevent foam stretching during manual assembly; differential silicone/acrylic for silicone foams.

3. Precision Finishing & Assembly Enhancements
Clean Center Slug Evacuation
Automated internal slug blow-out and matrix stripping ensures that interior gasket cutouts and screw holes are completely evacuated, eliminating assembly debris.
Extended Pull Tabs & Split Liners
Equipped with non-adhesive finger lift tabs, oversized border liners, or back-slit release paper to allow operators to peel backing in less than one second.
Anti-Stretch Carrier Reinforcement
For highly elastic sponge or thin PORON, we can laminate a thin PET film layer to eliminate dimensional stretching during high-speed manual installation.
Frequently Asked Questions
How do I choose between open-cell and closed-cell foam?
Closed-cell foams (EVA, PE, CR, Silicone sponge) prevent fluid penetration, making them mandatory for IP65–IP68 water sealing. Open-cell foams (like Rogers PORON®) excel at acoustic dampening, dust filtration, and long-term rebound without fatigue.
Can raw foams without glue be laminated with adhesive?
Yes. We regularly laminate plain EVA, CR, PORON®, or silicone sheets with 3M™ (such as 9448A, 467MP, 300LSE) or high-grade Crown (皇冠) double-sided tapes before rotary or flatbed die-cutting.
What dimensional tolerance can be held on soft foams?
Because foams are compressible, tolerances typically range from ±0.08 mm to ±0.2 mm depending on thickness and hardness. We verify all cut profiles non-destructively using 2D optical video measurement (VMM).
What payment methods and currencies do you accept?
We support standard USD T/T (SWIFT wire transfers) for global accounts. In addition, to help international buyers minimize SWIFT intermediary bank charges and transfer delays, we provide local domestic bank collections across most European and North American regions (supporting local transfers in EUR via SEPA, GBP, USD, and other major European currencies).
