Gearboxes For Plastic Extruders: How We Optimized Production For a Company in The Industry

The Challenge: An Inefficient Extrusion Process

An important company operating in the production of plastic pipes for the construction sector approached us with a critical problem: the gearboxes installed in their extruders frequently failed, leading to machine downtime and high maintenance costs. Production efficiency was compromised, and the company sought a solution capable of ensuring operational continuity and optimizing energy costs.

Our Analysis

After carefully evaluating the operational conditions of the equipment, our team identified the main issues:
Gearboxes not designed to withstand the high radial and axial loads from the extrusion screw (up to 250 kN axial thrust)
Inadequate cooling system, with operating temperatures exceeding 90°C
Excessive gear wear, resulting in efficiency losses and the need for extraordinary maintenance interventions
The goal was clear: replace existing gearboxes with high-performance solutions capable of operating under harsh conditions without compromising productivity.

Our Solution: Customized Gearboxes for Extruders

After analyzing the company's needs, we proposed a high-efficiency gearbox system featuring the following characteristics:

1. Reinforced Structure for High Torque
The new gearboxes were designed with reinforced helical gears made of hardened and ground steel, with gear modules exceeding 8 mm, capable of withstanding axial loads up to 300 kN without compromising long-term performance.

2. Advanced Cooling System
To prevent overheating and ensure continuous operation, we integrated a forced lubrication system with high-efficiency heat exchangers, maintaining operating temperatures below 70°C, extending lubricant lifespan and reducing premature wear risks.

3. Improved Energy Efficiency
With optimized gear design achieving efficiencies above 98%, low-friction tapered roller bearings, and advanced synthetic lubricants, the new gearboxes reduced energy consumption by 15% compared to previous solutions.

4. Predictive Monitoring and Maintenance
To minimize downtime and enhance maintenance management, we installed temperature, vibration, and oil pressure sensors, enabling real-time remote monitoring via an integrated IoT diagnostic system.

The Results: An Optimized Extrusion Process

Six months after implementing the new gearboxes, the customer reported significant improvements:

• 40% reduction in machine downtime due to improved gearbox reliability
• 15% decrease in energy consumption, resulting in operational cost savings
• 50% reduction in maintenance costs, due to decreased gear wear and predictive monitoring
• 20% increase in productivity, meeting higher demand without additional machinery investments
• 35% increase in gearbox lifespan through better load management and optimized lubrication.
