Industry: Metalworking & Forging

Location: Italy

Client: Forging Facility for Automotive Suspension Components

Related Product: Eurotec Hydraulic Oil HVLP 68

Client Background

The plant operates three high-tonnage hot forging presses producing suspension arms for European automakers. Each press cycles over 1,500 times per shift, with extreme thermal load on hydraulic oil reservoirs and cylinders.

Operational Challenge

Increased hydraulic drift at high temperatures, causing forging misalignment

Black sludge deposits inside reservoirs and around valve blocks

Cycle time degradation of up to 8%, reducing productivity

Excessive pump wear due to poor viscosity retention

 Solution

Eurotec replaced the existing oil with Eurotec Hydraulic Oil HVLP 68, featuring:

• Very high viscosity index (>160)
• Enhanced thermal oxidation resistance
• Varnish-free operation with superior shear stability under load

Offline filtration units and thermographic tracking were added as part of the reliability improvement plan.

Implementation Process

• System cleaned using Eurotec flushing agent
• Fill procedure conducted with fluid recirculation to remove contaminants
• Cylinder movement precision benchmarked before and after implementation
•  Performance monitored over two production quarters

Measured Results

• Cycle time improved by 5.6%, restoring throughput
• Stroke accuracy increased by 18%, reducing defective part rate
• Oil life extended from 3 to 9 months
• Pump replacement frequency halved, reducing component spend

Customer Statement

"This is the most consistent our press control has ever been. Eurotec gave us hydraulic precision without sacrificing durability."
