As part of QBF rubber's commitment to full lifecycle service for sidewall conveyor belts, the company recently organized a specialized hands-on training session on ST3150 B1500 steel cord sidewall conveyor belt jointing technology at its manufacturing base. The training was conducted using actual products from a Japanese power plant project, focusing on the critical jointing techniques under the "rope-free zone" design.

The training was led by a senior after-sales technical manager with over 10 years of field installation and jointing experience. The curriculum covered the complete jointing process for ST3150-grade sidewall belts, including steel cord preparation, stepped overlap layering, and vulcanization process control. Training samples were taken from the same production batch as the Japanese power plant order, strictly adhering to Japanese acceptance standards, ensuring every technical detail meets international client expectations.

Joint quality is decisive for conveyor belt service life and operational safety. For sidewall belts, jointing involves not only high tensile strength but also sidewall sealing and operational stability—making the process considerably more complex than standard conveyor belt jointing. The hands-on session emphasized "rope-free zone" operating procedures, achieving joint strength above 85% of the original belt while effectively preventing stress concentration and material leakage risks.

QBF rubber's after-sales service team has years of expertise in conveyor belt installation and jointing, with particular strength in large-lift-height, large-specification sidewall belts, as well as confined-space and challenging site conditions. Our technical core comprises professionals with over a decade of field experience, proficient in developing customized jointing solutions and troubleshooting across diverse operating environments. QBF rubber has established a rapid-response service network covering key industrial regions globally, implementing standardized quality management from site survey and solution design through to construction and final acceptance, ensuring every service delivery is precise and efficient.

From new belt installation to scheduled maintenance, from emergency repairs to belt replacement, QBF rubber upholds the service philosophy of "One Joint, Lifetime Protection," combining technical expertise with rapid response to minimize customer downtime and extend equipment service life.

Looking ahead, QBF rubber will continue to deliver superior workmanship and comprehensive conveyor belt lifecycle services, providing high-quality product delivery and on-site installation/maintenance solutions for customers worldwide.
