In today’s competitive plastics and advanced materials processing industry, upgrading legacy systems to a Smart Factory is no longer optional — it’s essential for survival and growth. Many manufacturers still rely on outdated manual material handling, separate drying units, and fragmented conveying lines, resulting in high energy consumption, moisture-related defects, and low overall equipment effectiveness (OEE).
This Smart Factory Material Automation Retrofit Guide draws on Wolter’s 20 years of expertise to provide practical, step-by-step insights for transforming traditional facilities into intelligent, efficient operations. As a global provider of material handling automation equipment and one-stop solutions, Wolter has helped over 120 countries upgrade their production lines with more than 22,000 installed units.
Why Retrofit to a Smart Factory Now?
The global push toward Industry 4.0 and sustainable manufacturing makes Smart Factory material automation a strategic priority. Retrofitting offers:
- 20-35% reduction in energy costs
- Significant decrease in moisture defects (silver streaks, bubbles, embrittlement)
- Improved traceability and real-time data monitoring
- Higher throughput and flexibility for multi-material production
Wolter’s Smart Factory solutions integrate dehumidification dryers, conveying systems, dosing and blending units, crystallization systems, and palletizing robots into a unified, intelligent ecosystem.

Step-by-Step Smart Factory Material Automation Retrofit Guide
Phase 1: Assessment & Planning (Weeks 1-4) Conduct a comprehensive audit of current material flow, drying efficiency, and bottlenecks. Wolter’s team typically evaluates:
- Resin types (hygroscopic vs non-hygroscopic)
- Current dryer performance (hot air vs dehumidifying)
- Conveying distance and contamination risks
- Existing automation level
Phase 2: Core Equipment Integration Replace or upgrade with Wolter’s flagship solutions:
- WDD-AZ Integrated Conveying Dehumidification Dryer: Combines feeding and drying in one compact unit, reducing footprint and energy use.
- PET/PLA Crystallization Systems: Essential for bottle-grade and biodegradable materials.
- Dosing & Blending Series: Precision gravimetric feeders for consistent compounding.
Phase 3: System Connectivity & Smart Controls Implement Wolter’s Software and Control series for centralized monitoring, predictive maintenance, and AI-assisted optimization — key features of a true Smart Factory.
Phase 4: Validation & Optimization Run pilot production, measure KPIs, and fine-tune. Most Wolter retrofits achieve ROI within 12-18 months.
