Top 5 Micro Injection Moulding Machines for Medical Applications in 2025
Micro injection moulding is at the forefront of medical device manufacturing—delivering minute, high-precision parts for diagnostics, drug delivery systems, microfluidics and minimally invasive tools. Find below the most advanced Micro Injection Moulding Machines for Medical Applications in 2025.
1. Wittmann Battenfeld MicroPower 15/10
Shot volumes: 0.05–4 cm³ via two-step screw‑and‑plunger design.
Precision: Sub‑0.1 g part weights; ±10–100 µm tolerances.
Clean‑room readiness: Fully enclosed cell accepts laminar‑flow module producing ISO 14644–1 Class 6 air; encapsulated drives are easy to clean. Envisaged as turnkey clean‑room production cell with integrated robot, rotary table and inspection camera (source).
Cost‑efficiency: Shorter cycle times and low energy/material waste can reduce costs by 30–50 % vs standard machines—critical when using materials at €2,000–5,000 / kg (source).

Clean‑Room Implementation Considerations for Micro Injection Moulding Machines
Air Purity Standards
ISO 14644-1 Class 6 laminar-flow environments have become the benchmark for producing micro-scale medical components, ensuring controlled airborne particle levels.
Hygienic Machine Architecture
Design features such as enclosed drive systems, smooth external surfaces, and sealed machine housings facilitate thorough cleaning and significantly reduce particulate contamination.
Optimised Space Utilisation
Tie-bar-free configurations (as seen in Engel machines) and modular, compact manufacturing cells (such as those from Wittmann) maximise floor space efficiency—especially valuable where clean-room expansion is impractical or cost-restrictive.
Built-In Quality Control
Integrated vision systems and robotic handling within the production cell support continuous in-line inspection, maintaining sterility while enabling 100% part validation without external intervention.
Cost‑Analysis & ROI Breakdown of Micro Injection Moulding Machines
| Cost Element | MicroPower 15/10 (All‑electric cell) | Standard Micro‑moulder |
| Machine cost | Higher upfront (electric drives & enclosure) | Lower (hydraulic or open-frame) |
| Energy consumption | ↓30–50 % (servo drives, reused regen power) | Baseline energy use |
| Material waste | ≪1 g sprue; micro gauges save €2k–5k/kg resin | Higher sprue weight; more waste |
| Labour & maintenance | Lower—automated removal/ inspection reduces staff | Requires manual inspection |
| Real-estate / CapEx | High density cells yield more parts per m² | More floor space per machine |
| Throughput | Fast cycles (~3–5 s), inline QC minimises downtime | Slower cycles, more manual steps |
Return on Investmen: Savings from material efficiency and energy alone can offset premium machine costs in under 12–18 months. Coupled with space‑efficiency in expensive clean‑room real estate and reduced labour, the ROI timeframe improves in high‑mix, low‑volume medical part production.
In 2025, micro injection moulding machines for medical applications share four key characteristics:
- Fine-control of shot volume and tolerance
- All-electric operation for energy, cleanliness, uptime
- Clean‑room compatibility via cell design and robotics
- Cost-efficiency from reduced waste, faster cycles, and integrated quality assurance
Choosing the right machine depends on:
- Required shot size and tolerance
- Handling of specialised materials (e.g., LSR, PEEK)
- Available clean‑room space and layout constraints
- Desired automation level and ROI timeline
