What We Manufacture
EKINSUN produces custom medical-grade injection molded plastic components for hospitals, medical device companies, distributors, and OEM manufacturers worldwide. Our core expertise is in fluid management components — the small but critical plastic parts that control, direct, and connect IV lines, catheters, and fluid delivery systems.
3-Way Stopcock
Standard and high-pressure versions. Custom handle colors and configurations.
IV Line Manifold
2, 3, and 4-port manifolds with integrated stopcocks for ICU and OR use.
Full Product Range
Complete stopcock and manifold line — multiple sizes and configurations available.
Custom Stopcock Variants
Different handle styles, colors, and port orientations to your specification.
Product Categories
3-Way Stopcocks
Our most requested medical product. We manufacture standard 3-way stopcocks in medical-grade polycarbonate with Luer lock or Luer slip connections. Applications include IV drug administration, arterial line monitoring, and hemodynamic pressure monitoring.
Available configurations: standard flow, high-flow, high-pressure (for contrast injection), with or without extension tube, male or female Luer, and multi-stopcock manifold assemblies.
IV Manifolds (Multi-Stopcock Bars)
Multi-port IV manifolds allow multiple infusion lines to be connected to a single catheter access point. We manufacture 2-port, 3-port, and 4-port manifolds with individual stopcocks on each port. Common in ICU settings and surgical suites.
Luer Lock Connectors & Fittings
Male and female Luer lock connectors, extension sets, and custom fittings for fluid management. All manufactured to ISO 594 / ISO 80369 thread standards. We can produce custom configurations not available off-the-shelf.
Contrast Injection Fittings
High-pressure rated components for use with power injectors in CT, MRI, and angiography procedures. Clear polycarbonate for visual flow confirmation. Rated for injector pressures up to 300 PSI.
Anesthesia & Breathing Circuit Components
Custom plastic connectors and fittings for anesthesia delivery systems and respiratory circuits. We work from your engineering drawings or can reverse-engineer from a sample component.
How to Order Custom Medical Parts
Send Your Drawing or Sample
Email your technical drawing, hand sketch, or an existing sample part to support@ekinsun.ltd. We sign NDAs before reviewing confidential designs.
Engineering Review & Quote
We review your design for moldability, select appropriate materials, and return a complete quote including tooling cost, unit pricing, and lead time — within 48 hours.
Mold Design & Sample
We design and manufacture the injection mold (typically 20-35 days), then produce T1 samples for your dimensional and functional verification.
Production & Delivery
After sample approval, mass production begins. Parts are inspected, packed, and shipped worldwide via DHL or FedEx with full documentation.
Have a hand drawing? We accept hand-sketched diagrams and photos of existing parts. Our engineers will redraw in CAD and send back for your confirmation before any tooling begins.
Materials
We injection mold a full range of medical-grade thermoplastics:
- Polycarbonate (PC) — High clarity, impact resistant. Used for stopcocks and manifolds where visual flow confirmation is needed.
- ABS — Good strength and surface finish. Suitable for housings and non-fluid-contact components.
- Polypropylene (PP) — Chemical resistant, autoclavable. Used where sterilization compatibility is required.
- Nylon (PA) — High strength and wear resistance. Used for connectors under mechanical stress.
- PEEK — High-temperature resistance, chemical inertness. Used in demanding surgical applications.
- TPE / TPU — Soft-touch overmolding, gaskets, and seals.
