ENERPAT Metal Chip Shredding & Oil Removal Line Case Study | Bosch China

ENERPAT Metal Chip Shredding & Oil Removal Line Case Study | Bosch China

Overview

Bosch, a global German industrial leader and one of the world’s largest automotive technology suppliers, operates across automotive technology, industrial engineering, consumer goods, and energy systems.

During daily machining operations, Bosch generates large volumes of oil-contaminated aluminum and iron chips mixed with cutting fluid (coolant). The factory faced increasing pressure from environmental regulations, rising disposal costs, and inefficient scrap handling processes.

To solve these challenges, Bosch required a custom metal chip shredding and coolant removal system to enable efficient recycling and compliant waste management.

Key Challenges
1. Unstable Scrap Processing Equipment

The existing waste handling system frequently broke down, resulting in:

Unplanned production downtime
Scrap accumulation in the workshop
Disrupted waste disposal workflow

This severely impacted operational efficiency.

2. High Cost of Metal Scrap Disposal

Because metal chips were mixed with cutting oil and coolant:

Scrap could not be directly recycled
Material was downgraded to hazardous waste classification
Disposal costs increased significantly

At the same time, valuable metal resources were being wasted.

3. Strict Environmental Compliance Requirements

Existing equipment failed to meet tightening environmental standards, leading to:

Repeated compliance inspection issues
Risk of production interruption
Pressure to upgrade waste treatment systems
4. Significant Economic Losses

Within one year, Bosch experienced:

High hazardous waste treatment fees
Increased maintenance and downtime costs
Loss of recoverable metal value

Total losses approached nearly RMB 1 million annually.

Customized ENERPAT Solution

After evaluating Bosch’s material type, oil content level, processing capacity, and available plant space, ENERPAT designed a fully integrated metal chip shredding and coolant separation line.

System Configuration

Elevator → Metal Chip Shredder → Conveyor System → Chip Wringing Machine (Oil Separator) → Coolant Recovery Unit

1. Compact Industrial Layout Design

Due to limited workshop space, ENERPAT engineers conducted multiple on-site assessments and optimized the layout to ensure:

Minimum footprint
Smooth material flow
Easy integration into existing production lines

The final design achieved a space-efficient, high-throughput configuration.

2. Closed-Loop Metal Chip Recycling System

The system forms a complete crushing + conveying + oil removal + fluid recovery loop:

Automatic elevator system reduces manual handling and increases feeding efficiency
Industrial metal chip shredder breaks tangled chips into uniform sizes for stable processing
Heavy-duty conveyor system ensures continuous and stable material transfer
Chip wringer / dewatering & deoiling machine (ED-400) removes up to 97% of cutting fluid
Coolant recovery system collects and filters separated oil for reuse

Result: zero wastewater discharge and maximum resource recovery.

3. High-Performance Metal Shredder & Chip Wringing Technology

The core of the system includes:

Industrial single shaft metal chip shredder
High-pressure chip wringer (oil extraction press)

This combination ensures:

No material clogging
Stable continuous operation
Maximum separation efficiency between metal and coolant
4. Industrial Reliability & Long Service Life

All equipment is built with:

Heavy-duty industrial components
Strict factory testing standards
Continuous operation design

This significantly reduces:

Equipment failure rate
Maintenance downtime
Production interruption risk
5. Full Lifecycle Engineering Support

ENERPAT provides a complete service chain:

On-site engineering assessment
Customized system design
Equipment manufacturing
Installation & commissioning
Long-term maintenance support
Project Results & Value Delivered

By implementing the ENERPAT metal chip shredding and coolant recovery system, Bosch achieved:
