The Challenge
Achieving Pharma-Level Cleaning & Coating Speed Without Sacrificing Cleanliness
The customer needed fast, repeatable processing of injection-molded components to stringent pharmaceutical standards, while minimizing contamination risk and maximizing output. Their needs included:
- High-speed washing and coating of plastic vials and cartridges
- Precise interior and exterior cleaning via multi-jet systems
- Consistent, closed-loop curing of commercial coating agents
- Compact footprints, cleanroom-grade enclosure, and traceable cycle times
MWES was selected for its ability to design cleanroom automation systems with tight cycle control and durable part cleanliness.
The Solution
Five-Stage Cleanroom Cell with Wash, Dry, Coat & Cure Functionality
MWES engineered a sealed automation cell that integrates sequential processing steps within an ISO‐rated enclosure:
- Exterior and interior high-pressure water jets for deep cleaning
- Dual-stage forced-air drying (external and internal) to eliminate residual moisture
- Proprietary coating spray module to uniformly apply treatment agent
- Curing stage with controlled temperature management via closed-loop feedback
- Positive-pressure cleanroom enclosure for contamination protection and compact footprint (< 10 ft wide)
The highly integrated design combines precision cleaning and coating flow with environmental controls to meet clean processing standards.
The Results
12-Second Cycle Time per Part, High Repeatability & Cleanroom Compliance
Post-installation benefits include:
- Consistent processing cycle of approximately 12 seconds per part
- Reduced contamination risk via fully enclosed and pressurized cell
- Improved coating uniformity and drying consistency across runs
- Minimized manual steps, maintaining operating benefits in clean-room environment
By automating the full component preparation and coating process, MWES helped the customer boost throughput, achieve medical-grade cleanliness, and deliver repeatable part quality—without operator-dependent variability.
