Vina Rubber is a specialized micro silicone components manufacturer focused on ultra-thin diaphragms, precision gaskets, and tight-tolerance elastomer parts for medical, sensor, and industrial applications.
We manufacture:
Micro silicone diaphragms
Silicone membranes
Precision silicone gaskets
Ultra-thin rubber components
While our standard catalog covers the most demanded sizes, Vina Rubber’s core strength lies in Custom Micro-Engineering. We transform complex technical drawings into high-performance rubber components with zero-defect consistency.
Our VINA-D and VINA-G series are strategically designed for sectors where failure is not an option:
Precision diaphragms for infusion pumps, respiratory ventilators, and diagnostic fluid control systems (USP Class VI & FDA Compliant).
Ultra-sensitive pressure sensors, fuel management diaphragms, and electric vehicle (EV) battery cooling seals.
Miniature pneumatic cylinders, micro-actuators, and high-frequency solenoid valve components.
IP68 waterproof gaskets and environmental seals for high-end consumer electronics.
We don't just mold rubber; we engineer performance. Our in-house material selection ensures longevity in extreme conditions:
Operating ranges from -40°C to +200°C for High-Temp Red Silicone.
Specialized EPDM and NBR formulations for oil, ozone, and chemical exposure.
High tear strength (up to 21 kN/m) for ultra-thin membranes (0.20 mm) that undergo millions of cycles.
In the world of micro-engineering, ±0.02 mm is the difference between a perfect seal and a system failure. Our facility utilizes high-speed automated molding and 100% micron-inspection protocols to ensure every single part meets your exact STEP/PDF specifications.
As a Sales Manager-led organization, we have eliminated the "waiting game."
Upload your technical files directly to our AppSheet-powered CRM.
In-house tooling capabilities allow us to move from design to sample in record time.
Integrated with UPS and FedEx for express door-to-door delivery to Europe, North America, and Asia.
Located in Hanoi, Vietnam, Vina Rubber offers a highly competitive alternative to traditional manufacturing hubs, providing superior quality-to-cost ratios and diversified supply chain security for international markets.
Our current achievements in micron-precision are merely the first steps. The true frontier of elastomer engineering remains uncharted. We invite you to explore the challenges we have yet to overcome and join us in redefining what is possible for humanity. [ View Our Global R&D Open Initiative ]
