Manufacturer of MDR Merge Spur Conveyors



Product Overview:
AstraRoll is a premier manufacturer and supplier of Custom 24V MDR (Motor-Driven Roller) Merge Spurs, designed to seamlessly combine product flows in high-throughput distribution and fulfillment centers. Operating on a decentralized 24V DC brushless motor platform, our merge spurs utilize intelligent "Run-on-Demand" logic, activating zones only when a parcel is present. This drastically reduces energy consumption by up to 70% compared to continuously running AC motors. Specifically engineered for Zero-Pressure Accumulation (ZPA), AstraRoll MDR modules ensure fragile cartons and polybags merge onto the mainline without colliding, eliminating product damage. As a factory-direct partner, we custom-build every spur frame and roller matrix to match your precise facility layout (30° or 45° angles), providing systems integrators with a true "plug-and-play" module that interfaces effortlessly with existing WMS and PLC networks.

Manufacturer of MDR Merge Spur Conveyors Details

Product Features & Engineering Specs
High-Speed Throughput Capability: Precision MDR zoning allows for seamless, high-rate package induction, safely merging up to 40 to 60 cartons per minute (CPM) onto the mainline depending on parcel length.
Plug-and-Play Architecture: Every module is factory-wired with standard industrial driver cards and M8/M12 quick-connect cables. Integrators can bolt the spur to the mainline and daisy-chain the power/logic in minutes, bypassing the need for expensive field wiring.
Ultra-Safe 24V Operation: The low-voltage DC architecture minimizes arc-flash risks and eliminates the need for heavy, high-voltage safety guarding, making it exceptionally safe for human operators to work alongside.
Industrial-Grade Construction: Built with heavy-gauge 10-D or 8-D powder-coated steel side channels and precision ABEC-1 bearings, designed to withstand 24/7 continuous shift operations.
Agile PLC Handshaking: Onboard control cards offer standard I/O, Ethernet/IP, or PROFINET communication, allowing your centralized WCS (Warehouse Control System) to dictate dynamic merge priorities on the fly.

Conveying Speed: Variable, up to 200 FPM (60 meters/minute).
Load Capacity: Up to 100 lbs (45 kg) per zone (Medium Duty).
Control Logic: Built-in ZPA (Zero Pressure Accumulation) with pre-wired photo-eyes.
Frame Material: Powder-Coated Steel, Aluminum, or Stainless Steel.
Why Choose AstraRoll? (Your B2B Partner)
Factory-Direct Customization
OEM Module Supply: We build "white-label" or custom-branded merge modules for global systems integrators. You provide the layout dimensions, and our factory provides the fully assembled, pre-tested hardware.
Flexible Drive Compatibility: We can equip our frames with industry-standard rollers and control cards (such as Itoh Denki, Interroll, or PulseRoller) based on your facility's existing spare-parts inventory, ensuring total fleet compatibility.
Engineering Expertise
Seamless Mainline Integration: We don't just sell the spur; we can supply the corresponding "receiver" mainline section, ensuring the roller spacing and transition plates are perfectly matched to prevent polybag snagging at the intersection.
Frequently Asked Questions (FAQ)
Q: Can MDR merge spurs handle flexible polybags and envelopes?
A: Yes. For polybag applications, we utilize tighter roller centers (e.g., 2" or 3" spacing instead of standard 4") and often apply high-grip polyurethane sleeves to the rollers to ensure lightweight, irregular packages don't slip or fall between gaps during the merge.
Q: Do I need a central PLC to control the Zero-Pressure Accumulation?
A: No. Our standard MDR driver cards feature "built-in" ZPA logic. Once you daisy-chain the zones together, they automatically communicate with each other to manage accumulation without requiring a master PLC. However, a PLC can be used if you want to apply complex routing or priority-merge rules.
Q: What maintenance is required for MDR systems?
A: Very little. Unlike chain-driven systems, there are no sprockets to grease or chains to tension. The brushless 24V motors are sealed for life. The only routine maintenance involves visually inspecting the photo-eyes for dust and occasionally replacing a snapped O-ring drive band.
Q: Can you manufacture these spurs in stainless steel for food environments?
A: Yes. As a custom manufacturer, we can build the entire frame out of 304 Stainless Steel and utilize IP66-rated washdown MDR rollers and waterproof sensors for strict sanitary compliance.
Q1. Are you a trader or direct factory?
We are a direct manufacturing factory with over 20 years of expertise in high-end industrial rollers, casters and material handling solutions. Our facility operates with ISO-certified quality management systems, allowing us to maintain full control over production cycles and quality standards. Throughout two decades of growth, we have established deep, long-term strategic partnerships with several listed companies and global automation leaders, proving our reliability as a high-tier industrial supplier.
Q2. What are your main products?
AstraRoll specializes in the engineering and production of three core product lines: Industrial Rollers, Heavy-Duty Wheels, and Precision Casters. We do not just sell components; we provide integrated movement and transport solutions. Our products are widely utilized across high-demand sectors, including: New Energy, Lithium Battery, Mining, Heavy Industry, Medical Institutional, Agriculture and Logistics.
Q3. What about delivery time?
We deeply understand that project timelines are critical.
Standard Products: Usually dispatched within 7–15 working days if the components are in stock.
Customized/OEM Orders: Depending on the complexity and volume, the lead time typically ranges from 20–35 days. This includes time for technical drawing confirmation, specialized tooling, and rigorous pre-shipment testing.
Shipping Methods: We offer flexible global logistics solutions, including FOB and CIF terms. We ship via Sea Freight (for bulk industrial orders), Air Freight (for urgent project needs), and International Express (DHL/FedEx/TNT) for smaller components or samples.
