Scale and consistency are the hallmarks of successful OEM partnerships. We recently completed a significant production run of 80 units of custom spur gears for a major rubber machinery company. These components serve as critical transmission elements in industrial curing presses, where they support the rigorous, repetitive cycles of the vulcanization process.
| Gear Type | Spur Gear |
| Module | M14 |
| Material | 40Cr Alloy Steel |
| Quantity | 80 Units |
| Processing | Gear Hobbing |
| Heat Treatment | Quenching & Tempering |
| Tooth Surface Treatment | High-Frequency Quenching |
| Accuracy Class | DIN 8 |
Module M14 sets the tooth size for the entire run, which is why all 80 gears were hobbed to one value and checked against a single pressure angle: any part from this batch drops into the client’s curing presses without re-shimming the drive train. The arithmetic behind that number, and how profile shift can throw it off, is set out in our guide on what is module in gear.
Project Highlights
Batch Manufacturing Excellence: Producing 80 units requires a robust quality control system. Our facility ensured that every single gear in this batch met the exact same tolerances, facilitating seamless assembly on the client’s production line.
Material Integrity: The choice of 40Cr steel, paired with quenching & tempering and targeted high-frequency quenching, provides the gears with the necessary toughness and surface hardness to handle the stress and heat associated with rubber curing operations.
Optimized Performance: Through precision gear hobbing, we achieved a DIN 8 accuracy level. The pressure angle in a gear is fixed at hobbing as well, which is why the tooth profile was verified against the drawing instead of being assumed from the module. Together they ensure reliable engagement and steady performance, reducing the need for frequent maintenance in the field.
Conclusion
By delivering this high-volume order on schedule and to strict specifications, we have reinforced our role as a trusted supply chain partner for the rubber machinery sector. These gears are now powering a new generation of curing presses, ensuring high productivity for end-users worldwide.
