Valves, diaphragms, connectors and seals.
Medical and healthcare device components
Custom medical LSR components from DFM review to traceable production.
PRESIS develops liquid silicone rubber valves, diaphragms, tube connectors and medical-direction seals for buyers who need stable dimensions, controlled processing and a clear project document trail.
Buyer pain points
Medical-direction LSR parts require more than a material name.
- Part geometry, venting, flash control and assembly fit must be reviewed before tooling.
- Cleanliness, post-cure and handling requirements need written confirmation.
- Small valves and diaphragms depend on repeatable thickness and functional response.
- Supplier approval often requires traceable material, inspection and change records.
PRESIS project route
Confirmed, recorded and traceable
Engineering reviews the drawing, function, tolerance, material direction and documentation needs before proposing the mold and sample route.
Requirements are recorded for tooling, molding, inspection and batch follow-up. Compliance files and testing are prepared according to the customer specification and applicable project requirements.
Parts and engineering questions
Start with the function, working environment and approval requirements.
| Component | Engineering focus | Information to send |
|---|---|---|
| LSR valve or diaphragm | Thickness, opening response, flash control and fatigue behavior. | Drawing, pressure or flow condition, media, life target and test method. |
| Tube connector or interface seal | Assembly fit, leakage risk, pull force and cleanliness. | Mating parts, tolerance, sterilization or cleaning condition and annual volume. |
| Custom medical-direction silicone part | Material selection, post-cure, color, appearance and traceability. | 2D/3D files, hardness, required documents, sample quantity and delivery target. |
