Sealing applications are extensively used in automotive industry. Sealing is applied to many parts of car because its features like leak proofing, anti-vibration and strengthening. Glass of car are mounted to the car by applying mastic. Similarly mastic is applied to other parts of car like hood, rear-front doors and sliding doors for preventing vibration and leak proofing. Producing more than one car model on the same production line, increasing production quantities and quality problems, robotic systems come to the fore instead of manual systems for sealer applications. Robotic automation improves sealing precision and controls bead cross-sections. Profitability is achieved by gains in productivity and also by optimizing adhesive consumption rates.
