Accurate Sealant Application for Reliable, High-Quality Assembly
In engine manufacturing and precision assembly, sealant application plays a critical role in ensuring leak-free performance, consistent product quality, and long-term reliability.
Manual sealant dispensing can lead to variation in bead width, uneven application, excess material usage, missed areas, and quality rejection. Shiran Engineering’s Engine Head Sealant Dispensing System is designed to automate the complete sealant application process with accuracy, repeatability, and traceability.
The system applies a controlled sealant path on engine head components and other precision parts, ensuring the right quantity of sealant is dispensed at the right location—every time.
Automated Sealant Path for Different Engine Head Parts
The system is designed to dispense sealant accurately across different engine head models and component variants.
Using programmed robotic paths, the dispensing nozzle follows the required sealant profile on each part. The system can handle complex geometries, curved paths, corners, bolt-hole areas, and different sealing surfaces.
This ensures consistent bead placement and reduces the dependency on manual operator skill.
The System Can Support
Different engine head models
Multiple sealant path profiles
Complex and curved dispensing patterns
Different component sizes and variants
Controlled bead width and height
Variant-based program selection
High-repeatability production requirements
Integrated Automation for Complete Process Control
The Engine Head Sealant Dispensing System is designed as a complete automation solution with multiple integrated devices.
The system can include:
Roller conveyor for part movement
360-degree turnover device for multi-side sealant application
Automatic stopper for accurate part positioning
Sensors for part detection and confirmation
PLC integration for complete electrical device control
Robot-based sealant dispensing system
Controlled pumping system based on sealant requirement
HMI interface for operation and monitoring
Safety guarding and interlocked access
Traceability and consumable monitoring options
Each device works in sequence to ensure the part reaches the correct position before dispensing begins.
360-Degree Turnover for Multi-Side Application
Some engine head components require sealant application on different faces or multiple sides.
The integrated 360-degree turnover device allows the component to rotate safely and accurately during the process. This enables the robot to access difficult locations without manual handling or re-clamping.
The turnover system improves process flexibility and supports complete sealant application in a single automated cell.
Benefits of the Turnover System
Multi-side sealant dispensing
Better robot accessibility
Reduced manual part handling
Improved safety
Faster process cycle time
Accurate and repeatable component orientation
Controlled Sealant Pumping for Consistent Dispensing
The dispensing robot uses a controlled pumping system based on the specific sealant requirement of the application.
The system can be configured to control:
Sealant flow rate
Dispensing pressure
Bead width
Bead height
Start and stop points
Corner accuracy
Material quantity per component
Dispensing speed
This ensures that the required amount of sealant is applied consistently across every part.
Accurate dispensing helps reduce sealant wastage while maintaining the required sealing performance.
Improve Quality and Reduce Rejection
A controlled robotic dispensing system improves product quality by eliminating common manual dispensing issues.
Key Quality Benefits
Accurate sealant bead placement
Uniform bead width and height
Reduced missed dispensing areas
Reduced excess sealant application
Better leak prevention
Lower rejection and rework
Consistent output across production shifts
Improved process documentation
The system can also support visual inspection, sensor confirmation, and traceability integration for improved quality assurance.
Track Sealant Consumption and Production Data
Sealant is a critical consumable in many assembly processes. The system can be integrated with production monitoring and consumable tracking features.
This helps manufacturers monitor:
Sealant consumption per component
Material usage by shift or batch
Production quantity
Cycle time
Dispensing program selection
Alarm history
Downtime and maintenance requirements
Quality-related process data
This visibility supports better material planning, cost control, and continuous process improvement.
