Forever Electromechanical Delivers Custom Piston Rod Heat Treatment Production Line to Serbia
Introduction
Recently, the customized piston rod heat treatment production line independently developed and manufactured by Forever Electromechanical has completed full-load factory testing, standardized packaging and international shipment, achieving successful delivery to a professional construction machinery parts manufacturer in Serbia. After the equipment arrived at the customer’s factory, our overseas engineering team completed on-site installation, commissioning and thermal test run, and the production line has been officially put into mass production of precision piston rods. The successful implementation of this project marks another solid step for Forever Electromechanical in expanding the Central and Eastern European market, fully demonstrating the international competitiveness of China’s advanced IGBT induction heating technology in the high-precision metal heat treatment industry.
Project Background: Solving Customer’s Production Pain Points
The Serbian customer is a local core manufacturer of hydraulic cylinder piston rods, whose products are widely supplied to the European construction machinery and hydraulic system supply chain. For a long time, the factory adopted traditional box furnace
induction heat treatment equipment, which exposed many bottlenecks in actual production. The traditional equipment features long heating cycles, serious surface oxidation and decarburization of workpieces, and unstable overall hardness of piston rods, resulting in unqualified straightness accuracy. In addition, the old equipment has high energy consumption and low automation, only supporting intermittent production, which severely restricts the enterprise’s production capacity and order expansion.
With the EU’s increasingly stringent standards for wear resistance, dimensional accuracy and green low-carbon production of hydraulic parts, the original production equipment could no longer meet market and production upgrading demands. After in-depth comparison of multiple European and Asian equipment suppliers, the customer finally chose Forever Electromechanical and purchased a complete set of customized continuous induction quenching and tempering production line for piston rods.
Customized Solution: European Standard IGBT Induction Heating Production Line
Combined with local power grid parameters, piston rod product specifications and European industrial process standards in Serbia, Forever Electromechanical’s technical team has completed targeted optimization and upgrading of the whole production line. The production line is equipped with high-performance IGBT medium-frequency induction power supply, matched with roller conveying system, segmented induction coils, infrared closed-loop temperature measurement device and PLC centralized intelligent control system.
It realizes integrated automatic processes including automatic feeding, uniform penetration heating, segmented spray quenching, constant temperature tempering and automatic blanking. Aiming at the structural characteristics of long shaft piston rods, the equipment adopts uniform rotating conveying technology to ensure consistent heating of the rod body, effectively reduce quenching deformation and greatly reduce workpiece oxidation. The system can intelligently adjust power, running speed and cooling flow according to different piston rod materials and specifications, controlling the hardness error within a tiny range and greatly reducing subsequent finishing costs. Meanwhile, the whole equipment complies with EU safety and environmental protection standards, featuring no open flame, low noise and low energy consumption, which fully meets Serbia’s green manufacturing requirements.
On-site Commissioning and Production Verification
After the equipment arrived at the Serbian factory, Forever Electromechanical’s professional overseas service team rushed to the site to complete mechanical alignment, power system debugging and process curve calibration. In addition, we provided systematic professional training for the customer’s on-site operators and maintenance personnel to ensure proficient and standardized operation of the equipment.
After continuous production verification and thermal test run, all core indexes of finished piston rods, including hardness, metallographic structure and straightness, fully meet European industry standards. The production line operates stably with efficient production rhythm, significantly lower comprehensive energy consumption than traditional equipment, and a sharp drop in product defect rate. The customer’s person in charge highly recognized Forever’s equipment and services, stating that the new automated production line completely solves the long-standing problem of unstable product quality, effectively improves production efficiency and core product competitiveness in the European market.
Deep Cultivation of Central and Eastern European Market, Empower Global Intelligent Manufacturing
As an important node country of the Belt and Road Initiative in Central and Eastern Europe, Serbia has become a key overseas market for Forever Electromechanical’s strategic layout. With more than 20 years of R&D and manufacturing experience in induction heating equipment, the company provides turnkey solutions for heat treatment of piston rods, steel bars, steel pipes and other metal workpieces, with products exported to Central and Eastern Europe, Russia, the Middle East, South America, Southeast Asia and other global regions.
Facing the increasingly high requirements for equipment stability, energy efficiency and customized technology in the Central and Eastern European precision parts market, Forever Electromechanical will continue to iterate and upgrade
IGBT induction heating power supply core technology, optimize overseas project delivery standards and after-sales service system, and provide global metal processing enterprises with efficient, energy-saving and reliable integrated heat treatment solutions.
Conclusion
The smooth delivery and commissioning of the Serbian piston rod heat treatment production line is another benchmark overseas project of Forever Electromechanical in Central and Eastern Europe. This cooperation not only helps local customers realize production upgrading and quality improvement, but also further enhances the international influence of Chinese intelligent manufacturing in the European high-end industrial equipment market. In the future, Forever Electromechanical will adhere to technological innovation and quality-oriented development, continue to expand global overseas markets, and create greater value for global industrial customers with professional customized solutions and high-quality services.
