Best ZLYJ Series Extruder Gearbox for Plastics: Affordable, Reliable

🔧 Helmedrive ZLYJ Series Extruder Gearboxes: Engineered for Reliability and Cost Efficiency 

For plastics, rubber, and chemical processors, the challenges of sourcing critical machinery components are well 

understood: high local markups, protracted delivery schedules, limited customization options, and inconsistent 

after-sales support. Helmedrive offers a direct, technically robust alternative. With over two decades of manufacturing 

experience and certifications including UL, CE, and ISO9001, we engineer ZLYJ Series extruder gearboxes that deliver 

measurable operational and financial benefits.

💰 Direct-from-Manufacturer Value: Up to 40% Cost Savings

By eliminating regional distributors and selling directly from our ISO-certified facilities, Helmedrive reduces procurement 

costs by an average of 30 to 40 percent compared to local supplier pricing without compromising on quality. Our ZLYJ 

gearboxes are built with case-hardened and ground gears (accuracy Grade 6 or higher), high-load-capacity bearings, 

and double-lip shaft seals to ensure long service life even under continuous heavy-duty extrusion. The result is a 

cost-effective solution that meets or exceeds international standards.

⚙️ Technical Specifications and Customization

The ZLYJ Series covers a broad torque range top to 42,000 N·m, accommodating extruder screw diameters from 30 mm 

to 200 mm and above. Each gearbox is designed for:

🔹 High transmission efficiency: Optimized gear geometry and low-friction bearings achieve efficiencies up to 97 percent, 

      reducing energy consumption and operational costs.

🔹 Robust construction: Finite element analysis (FEA)-optimized housings minimize vibration and noise while ensuring 

      rigidity under full load.

🔹 Flexible mounting: Standardized input and output dimensions allow direct replacement of most existing gearbox brands 

      with minimal modification.

🔹 Custom engineering: For specialized applications such as high-torque rubber extruders or chemical pelletizing lines, our

      engineering team can adapt gear ratios, shaft configurations, and cooling systems to match your exact process requirements.

📊 Real-World Performance: Case Studies from Southeast Asia

The following examples illustrate how Helmedrive's ZLYJ gearboxes have addressed specific operational challenges for 

customers across the region.

📌 Case Study 1: Indonesian Film Extruder Reduces Downtime and Energy Costs

📍 Company: Plastic film manufacturer, Jakarta
📍 Application: 90 mm single-screw extruder for LDPE film
📍 Challenge: The customer's existing ZLYJ200 gearbox required replacement. A local distributor with a 12-week lead time, 

      which would have forced a production halt and significant revenue loss.

📍 Solution: Helmedrive supplied a ZLYJ250 gearbox (torque rating 6,500 N·m) within six weeks, a 40 percent saving. The unit 

      was a direct fit, requiring no modification to the extruder baseplate or coupling.
📍 Results:

• ✅ Production continued uninterrupted; the gearbox was installed during a scheduled maintenance window.

• ✅ Post-installation power monitoring showed a 15 percent reduction in energy consumption per ton of output, attributed to

        the higher efficiency of the new gearbox.

• ✅ When alignment questions arose during commissioning, remote technical support via video call resolved the issue within

        two hours, avoiding any start-up delay.

📌 Case Study 2: Vietnamese Rubber Extruder Achieves Higher Throughput with Custom Gearbox

📍 Company: Rubber profile manufacturer, Ho Chi Minh City
📍 Application: 160 mm rubber extruder for automotive sealing strips
📍 Challenge: No local supplier could offer a gearbox capable of delivering 25,000 N·m continuous torque while matching the 

      existing machine's input speed and mounting dimensions. Custom orders from Europe involved lead times of 16+ weeks and 

      prohibitive costs.
📍 Solution: Helmedrive engineered a custom ZLYJ450 gearbox with a special ratio and reinforced bearings to handle the torque 

      requirement. The unit was delivered in eight weeks, fully tested and ready for installation.
📍 Results:

• ✅ The new gearbox enabled the extruder to operate at 20 percent higher screw speed without exceeding thermal limits,

        increasing overall line output.

• ✅ Energy consumption per kilogram of product decreased by 12 percent, thanks to the gearbox's optimized efficiency.

• ✅ Remote calibration support from Helmedrive's engineers ensured proper alignment and lubrication settings in a single

        remote session, minimizing commissioning time.

📌 Case Study 3: Thai Chemical Pelletizer Cuts Maintenance Costs and Response Time

📍 Company: Chemical compound producer, Bangkok
📍 Application: 120 mm twin-screw extruder for plastic pellets
📍 Challenge: Frequent gearbox failures and slow local support (average three-day response) were causing extended production 

      stoppages. The last failure alone resulted in an estimated $5,000 loss due to idle labor and missed orders.
📍 Solution: The customer replaced their existing unit with a Helmedrive ZLYJ315 gearbox, selected for its robust design and the 

      promise of 24/7 remote assistance.
📍 Results:

• ✅ During the first month of operation, a minor lubrication issue was detected; Helmedrive's remote support team diagnosed

        and guided the local maintenance crew through a fix in 45 minutes, preventing any downtime.

• ✅ Annual maintenance costs have dropped by 28 percent due to the gearbox's extended oil-change intervals and reduced

        wear-related repairs.

• ✅ The customer now has a direct line to Helmedrive's technical team for ongoing support, eliminating the delays previously

        experienced.
