What Are the Best VLM Options for Manufacturing Operations?
How Vertical Lift Modules Streamline Manufacturing Ops and Improve Efficiency
Manufacturers are under constant pressure to optimize space, increase accuracy, and drive down operational costs. Automation is the clear path forward—but not all solutions deliver the same value. Vertical Lift Modules (VLMs) stand out for their space-saving design, speed, and high capacity. These automated storage and retrieval systems bring efficiency to the forefront with a goods-to-person solution that helps teams gain control, save space, and work smarter. As demand grows for intelligent, space-saving systems, VLM automation is quickly becoming the go-to strategy for manufacturing operations—keeping facilities competitive, agile, and future-ready.
What is a Vertical Lift Module (VLM)?
A VLM solution is a type of automated storage and retrieval system (ASRS) that uses a vertical design to store items in trays between two columns. A motorized inserter/extractor automatically delivers stored items to an ergonomic access point, eliminating search and travel time for workers.
Unlike traditional shelving or horizontal carousel systems, VLMs use height to maximize storage capacity within a minimal footprint. They’re especially valuable in manufacturing environments where quick, accurate access to parts, tools, or components is critical to workflow efficiency.
Advantages of VLM for Manufacturing:
- Space Optimization – Maximize vertical space and reduce the storage footprint
- Improved Pick Speed & Accuracy – Automated item delivery reduces human error
- Inventory Control – Real-time visibility and tighter control over stored items
- Enhanced Safety – Ergonomic design minimizes strain and improves worker safety

When it comes to choosing the right VLM for your operation, Modula delivers a powerful combination of performance, flexibility, and scalability. As Apex’s trusted automation partner, Modula offers advanced VLM technology built to meet the real-world demands of manufacturing environments.
From small tools to heavy components, VLMs are designed to adapt to your inventory profile and grow with your operation. With modular configurations, intuitive controls, and seamless integration with host operating systems, these solutions help manufacturers reduce downtime, improve inventory access, reclaim floor space, and scale storage capacity as needs evolve.
Top Modula VLM Options:
- Modula Lift – A high-capacity solution ideal for storing heavy-duty parts, tools, and materials with pinpoint accuracy. Ideal for facilities requiring rapid access to a diverse range of SKUs within a compact footprint.
- Modula Slim – Built for environments where every inch counts. This compact model delivers the same automation and storage efficiency in a narrower frame—ideal for smaller manufacturing spaces.
- Modula OnePick – Combines the power of VLM storage with a robotic picking system for fully automated retrieval. Perfect for high-volume, lights-out, or precision-critical applications.
Each system is fully customizable and scalable, giving you control over tray configurations, weight capacity, height, and integration with your WMS, ERP, or other host systems. VLMs are built to deliver long-term operational value and fast ROI.
Best Use Cases for VLMs in Manufacturing
Vertical Lift Modules are incredibly versatile—here are some of the most impactful use cases where VLMs deliver measurable value:
- Tool and Parts Storage
Store everything from small components to heavy tools in organized trays that can be retrieved quickly and accurately. Modula VLMs feature adjustable tray heights and widths, with impressive net payload capacities ranging from 500 to over 2,000 lbs.—making them ideal for managing diverse and heavy inventory with ease. - MRO Inventory (Maintenance, Repair, and Operations)
Keep critical spare parts, consumables, and service tools readily accessible while maintaining tight inventory control. With optional access control features like badge scanning or user-level permissions, VLMs help prevent unauthorized access and improve accountability. They also ensure high availability for maintenance teams—without the risk of overstocking or reliance on manual tracking. - Assembly Line Replenishment
Streamline the flow of parts and materials to the production line with fast, ergonomic access to commonly used items. With pick speeds of up to 300 lines per hour, VLMs support lean manufacturing principles by enabling just-in-time delivery, minimizing wait times, and reducing downtime. - Quality Control and Testing Environments
Securely store precision tools, test equipment, or production samples in a clean, controlled environment. The automation and traceability features of VLMs enhance process reliability and documentation.
Each of these use cases takes full advantage of the VLM’s core strengths: high-density storage, secure and efficient access, and real-time inventory visibility. Whether you’re supporting production, maintenance, or quality assurance, VLMs bring structure and speed to the most critical areas of your operation.
What to Consider When Choosing a VLM
Selecting the right VLM unit(s) requires more than just measuring available space—it’s about aligning the system with your operational goals, facility layout, and inventory characteristics.
Here are the key factors to evaluate:
- Ceiling Height and Floor Space
VLMs capitalize on vertical real estate, so understanding your facility’s clear height is critical. Modula systems are available in a variety of heights to optimize every available inch. - Inventory Type: Size, Weight, and Volume
From small electronics to heavy machine parts, your stored items determine the tray configurations and load capacities required. Modula VLMs offer flexible tray heights and widths, with payload capacities ranging from 500 to over 2,000 lbs per tray to accommodate varying inventory profiles. - Throughput Requirements
How quickly do you need to access inventory? Modula VLMs can reach pick speeds of up to 300 lines per hour, making them a great fit for high-throughput environments like assembly lines or MRO departments. - Integration with Existing Systems
For maximum efficiency, your VLM should integrate with your current WMS, ERP, or host software. Modula’s systems are designed for seamless integration, allowing for real-time inventory updates, order tracking, and process automation. - Security and Access Control
If sensitive or high-value inventory is involved, access control becomes essential. Modula VLMs can be configured with user permissions, badge scanning, and audit trails to ensure only authorized personnel retrieve items.
