THE CHALLENGE: High Cost of Liquid Silicone (LSR)
Memetis, a leading German high-tech firm, required custom membranes for their advanced Micro-valves.
Technical Requirement: 0.21 mm thickness with a strict tolerance of ±0.03 mm.
The Problem: German suppliers proposed Liquid Silicone Rubber (LSR) technology. While precise, the tooling and part costs were prohibitively expensive, threatening the project’s commercial viability.

THE VINA RUBBER STRATEGY: High-Consistency Rubber (HCR) Innovation
Vina Rubber challenged the industry status quo. We proposed using Solid Silicone (HCR) combined with our proprietary In-house Micro-tooling technology.
Material: Medical-grade, Platinum-cured Solid Silicone.
Engineering Edge: Our team didn't just meet the requirement; we exceeded it. While the client requested ±30 μm, we stabilized the production at an incredible ±20 μm (±0.02 mm).
THE PERFORMANCE MATRIX
1. Dimension Control (Thickness)
Requirement: 0.21 mm thickness.
Result: 0.21 mm thickness.
Evaluation: 100% compliance with German engineering blueprints.
2. Precision Tolerance (Accuracy)
Requirement: ±30μm (±0.03mm).
Result: ±20μm (±0.02mm).
Evaluation: Superior. Exceeded expectations by 33%, ensuring higher stability for micro-valve actuation.
3. Manufacturing Cost (Efficiency)
Requirement: Significantly lower than European LSR (Liquid Silicone) quotes.
Result: Reduced to 1/4 (75% Cost Saving).
Evaluation: Massive profit optimization for the client by utilizing Vina Rubber’s proprietary Solid Silicone (HCR) compression logic.
4. Production Speed (Lead Time)
Requirement: Professional R&D lead time for rapid testing.
Result: 15 Days for prototypes.
Evaluation: Ultra-fast response, drastically shortening the client's New Product Introduction (NPI) phase.
5. Surface Texture (Anti-Stiction)
Requirement: Zero-stiction for reliable micro-actuation.
Result: Premium Matte Finish.
Evaluation: The refined matte surface eliminates surface tension (stiction), ensuring the membrane detaches instantly during valve opening.
6. Material Safety (Integrity)
Requirement: Medical grade with high tear strength.
Result: Platinum-cured Silicone (21 kN/m).
Evaluation: Certified safety with high durability, ideal for long-cycle life in precision medical devices.
TECHNICAL EVIDENCE & QUALITY ASSURANCE
Our Micron-inspection workflow ensures that 100% of the 5,000-piece batch adheres to these extreme tolerances.
Visual Precision: Ultra-thin, non-stiction membranes optimized for micro-actuators.
Dimensional Verification: Verified using high-precision Mitutoyo digital micrometers, showing a consistent 0.21 mm readout across the entire surface.
Design Alignment: Perfect synchronization between the German CAD specifications and the final physical output.
"Vina Rubber didn't just replace German LSR technology with a more cost-effective solution; they delivered a level of precision that we previously thought was only possible with liquid injection." — Memetis Engineering Feedback.
