As a leading enterprise in China's machine tool equipment sector, the Shandong-based company specializes in the R&D and manufacturing of large-scale precision stamping equipment and intelligent production lines. Its products are widely used in high-end manufacturing fields, such as automotive and aerospace. In the production of large machine tools, the stable operation of hydraulic systems and spindle units directly determines machining accuracy and equipment service life, with precise temperature control being critical for system stability.
II. Core Pain Points: Heat Exchange Challenges in Process Upgrading
Insufficient Temperature Control Accuracy: The hydraulic system required a stable operating temperature of 35–40°C. The previous equipment experienced fluctuations of up to ±3°C, leading to changes in hydraulic oil viscosity, reduced operational accuracy, and an increase in out-of-tolerance machined parts.
Low Heat Transfer Efficiency: During simultaneous operation of multiple production lines, the heat exchange equipment failed to dissipate heat quickly. In summer, frequent shutdowns for cooling resulted in a daily production loss of over 1.5 hours.
High Operational and Maintenance Costs: The equipment was prone to scaling and clogging, requiring shutdowns for cleaning 2–3 times per month. This increased maintenance labor costs and shortened equipment service life.
III. Customized Solution: Precision Empowerment with Plate Heat Exchangers
In response to the process characteristics and pain points, a dedicated technical team conducted in-depth on-site research. Custom-developed high-efficiency plate heat exchangers and supporting temperature control systems were introduced, offering four key advantages: precision, efficiency, energy savings, and convenience.
Core Configuration: Tailored to High-End Manufacturing Needs
Efficient Heat Transfer Structure: Features herringbone corrugated plates made of 316L stainless steel, with plate spacing optimized to 2.5 mm. The heat transfer coefficient increased by 45% compared to traditional equipment, enabling rapid heat balancing in hydraulic systems and spindle units.
Intelligent Temperature Control System: Integrates imported platinum resistance temperature sensors and variable frequency control modules for real-time medium temperature monitoring. Temperature control accuracy remains stable at ±0.5°C, meeting precise process requirements.
Compact Design and Anti-Corrosion Optimization: Utilizes a modular skid-mounted structure, occupying only one-third the volume of traditional equipment. Plate surfaces undergo electrolytic polishing, improving anti-scaling capability by 60% to suit workshop water quality.
Service Assurance: Seamless End-to-End Implementation
Provides full-process services, including site surveys, solution design, equipment manufacturing, installation, commissioning, and personnel training.
IV. Application Results: A Leap from Compliance to Leadership
Since deployment six months ago, performance has exceeded expectations, delivering significant process and economic improvements:
Hydraulic system temperature control stabilized at ±0.5°C, reducing the out-of-tolerance rate of machined parts by 90%.
Enabled 100% continuous production during summer, increasing daily production time by 1.5 hours.
Reduced energy consumption of the heat exchange system by 30%, with annual electricity savings exceeding ¥180,000.
Maintenance frequency decreased from 2–3 times per month to once per quarter, lowering operational and maintenance costs by 70%.
V. Client Feedback: A Trusted Choice for Mutual Success
“The new plate heat exchangers have completely resolved our long-standing temperature control challenges. Equipment accuracy and stability have significantly improved, ensuring smooth delivery of high-end orders while reducing energy consumption and maintenance costs. The team’s customization expertise and efficient service demonstrated the value of in-depth collaboration, strongly supporting our journey toward green intelligent manufacturing.”
