A leading Tier-1 automotive supplier approached D S Techno Rubber Pvt. Ltd. with a strategic goal: localize an imported AdBlue pump assembly to reduce costs, improve lead times, and gain full control over quality.
However, the project started with a major constraint—no technical drawings, material specifications, or design data for the 13 rubber components used in the system.
AdBlue Pump Localization Challenge in Automotive Manufacturing
The AdBlue pump is a critical component in emission control systems, handling urea-based AdBlue fluid and diesel under demanding operating conditions.
The customer needed to:
- Replace imported components
- Maintain OEM-level performance
- Ensure long-term durability and chemical resistance
Any deviation could impact emission compliance and system reliability.
Reverse Engineering Approach for Rubber Parts Development
Dimensional Mapping & Geometry Reconstruction
With no compound data available, we conducted fluid compatibility testing to identify suitable materials.
We developed custom rubber formulations such as:
- EPDM for AdBlue resistance
- FKM for diesel exposure
- Application-specific elastomer blends
Custom Rubber Moulding and Tool Development
We designed and developed dedicated moulds for each part:
- Compression moulding for structural components
- Transfer moulding for precision parts
Focus areas included:
- Tight flash control
- Process repeatability
- Optimized cycle time
Rubber-to-Metal Bonding for Automotive Applications
For diaphragm assemblies and bonded components, we implemented:
- In-house metal preparation systems
- Advanced bonding technologies
- High adhesion performance under chemical exposure
Explore our rubber to metal bonded components for similar applications.
Prototyping, Testing & Validation
Each component was validated through:
- Fitment testing in pump assembly
- Hardness and compression testing
- Chemical resistance validation
Final approval was achieved through system-level testing with the customer.
Results: AdBlue Pump Component Localization Success
DST successfully developed all 13 rubber components, enabling full localization of the pump system.
Key outcomes:
- Complete replacement of imported components
- Reduced supply chain dependency
- Improved lead times and cost efficiency
- Consistent OEM-grade quality
