High productivity through fully automatic operation and short cycle times
The new MP 3150 eccentric closed-die forging press from SMS group is designed for the production of track links for excavators at TZCO Chain Manufacturing in Jinzhong City, Shanxi Province, China. With this plant, TZCO can manufacture a key safety- and performance-relevant component for the construction equipment industry in a highly efficient and reliable way.
The fully automatic forging line combines high output, short cycle times, and precise process control to support stable serial production. With a nominal press force of 3,150 tons (31.5 MN), a maximum stroke rate of up to 30 strokes per minute, and a cycle time of up to four seconds per part, the plant is engineered for demanding production requirements. The installation includes an electric walking beam transfer system, servo drives on every axis, automatic die lubrication and spray systems, a quick-change die holder, and a duplex bolster changing car.
For TZCO, this means higher productivity, reduced material consumption, and lower downstream machining effort. At the same time, the plant helps ensure consistent forging quality, reliable process stability, and greater flexibility in day-to-day operation. This enables TZCO to strengthen its manufacturing capabilities and meet market demand with a modern and efficient forging solution.
Key benefits at a glance:
- High throughput and speed: The fully automatic press achieves up to 30 strokes per minute, delivering cycle times as fast as 4 seconds per piece for excavator track links.
- Significant material and cost savings: By utilizing advanced flash-minimizing technology and precision punching, the system reduces raw material waste, energy consumption, and the need for downstream machining.
- Enhanced precision and quality: Integrated process development—including forging simulations and optimized startup/deceleration ramps—ensures high part accuracy and consistent manufacturing quality.
- Advanced automation for durability: The electric walking beam transfer system and automated lubrication reduce mechanical wear and guarantee smooth movements, extending the machine's operational life.
- Data-driven productivity: A customized digitalization package provides real-time monitoring of energy and production KPIs via a large-scale dashboard, allowing for immediate insights and optimized performance.
SMS has delivered an excellent complete package: a highly automated press with sophisticated technology. The press enables TZCO to expand its excavator business by producing track links in a new forging shop. Thanks to the high accuracy and minimal flash of the forging process, we achieve material savings and lower production costs.
