Overview
Our Personalized 13.3mm Medical-Grade Silicone Rubber Dispenser Valves with Mess-Free Cross-Slit service solution is engineered for demanding medical and clinical dispensing applications that require precise one-way flow control, absolute leak prevention, and full biocompatibility. Manufactured from ISO 10993-compatible, platinum-cured LSR, each 13.3 mm valve is produced via high-precision LSR injection molding and micro-slit cutting to deliver repeatable opening pressure, long fatigue life, and contamination-resistant performance. We offer turnkey OEM services — from DFM and rapid prototyping to sterile packaging and volume production — tailored to medical device, diagnostic, and pharmaceutical dispensing requirements.

Key Benefits
- Medical-Grade Biocompatibility — Platinum-cured LSR with traceable material lots and support for ISO 10993 testing ensures safe patient contact.
- True Mess-Free Dispensing — Precision cross-slit geometry delivers controlled one-way flow with no dripping, backflow, or contamination.
- Tunable Performance — Slit profile, wall thickness and Shore A hardness are engineered to match target opening pressure and fluid viscosity.
- Turnkey Medical OEM Service — DFM, rapid prototyping, validated tooling, cleanroom assembly, and sterilization support for regulated markets.
Quality Assurance & Testing
We enforce a strict QA program tailored to medical supply chains:
- Incoming Material Control: Certificate of Analysis (CoA), FTIR/XRF batch verification and lot traceability.
- Dimensional & Surface Control: ZEISS CMM and 3D optical inspection for slit geometry and critical dimensions (±0.01–0.02 mm).
- Functional Verification: Leak and backflow testing, opening-pressure profiling, flow-rate curves with representative fluids, and long-cycle fatigue tests (actuation lifecycle).
- Mechanical & Physical Tests: Shore A hardness, tensile and tear tests, compression set, and thermal aging.
- Biocompatibility & Sterilization Validation: Support for ISO 10993 testing and validation of EtO/gamma sterilization protocols per client requirements.
- Regulated Documentation: Full inspection reports, batch traceability, and PPAP/DFMEA documentation available on request.
Type of Silicone Valves (selection)
- Cross-Slit Valves (13.3 mm) — Optimized for mess-free one-way dispensing of low-to-medium viscosity fluids.
- Duckbill Valves — Low backpressure discharge for thicker media.
- Umbrella Valves — High sealing force and pressure relief applications.
- Multi-Slit / Snowflake Patterns — Increased flow area with redundant sealing for specialty dispensers.
Factory Capabilities (summary)
Our cleanroom-enabled facility uses advanced moldmaking and molding technologies: multi-axis CNC, Mirror EDM, precision wire cutting for micro-slit tooling, automated LSR injection molding and compression presses, plus cleanroom final assembly (ISO 7/8 options). In-line and lab testing include 3D projectors, CMM, leakage testers, durometers and automated actuation rigs. We offer rapid prototyping, small pilot runs, and validated scale-up to high-volume production with ISO 13485/9001 governance and sterile packaging options.
