As one of the world's major natural rubber producers, the Philippines’ rubber product processing industry is a pillar of its local economy, particularly in the manufacturing of tires, rubber belts, and shoe materials. During these production processes, key stages such as vulcanization, drying, and calendering require a stable and substantial supply of steam heat. So steam boilers are critical equipment for this industry that they can provide steady and sufficient steam for vital processes like vulcanization, drying, and molding—directly impacting product quality and production efficiency. Stable steam supply enables precise control of temperature and time that significantly improve vulcanization quality and drastically reduce defect rates in rubber vulcanization. Additionally, high boiler evaporation capacity demands equipment that can quickly meet on-line steam requirements to boost productivity.A well-known rubber factory in Mindanao, Philippines, had long relied on expensive oil-fired boilers. Th customer faced immense pressure from high production costs. Meanwhile, the Philippines boasts abundant agricultural waste resources, including coconut shells, wood chips, and rubber wood processing residues (wood flakes). The enterprise wanted to seek an efficient, economical, and environmentally friendly steam solution to cut energy costs, achieve resource recycling, and enhance market competitiveness. After market research and rigorous screening, They chose Xinli Boiler to be their steam boiler supplier—this also marks a new strategic step for Xinli Boiler in expanding its overseas market presence. Xinli Boiler’s technical team analyzed the customer’s specific needs and leveraged local fuel advantages to customize an SZL20-2.5/400-SCII type double-drum coal and biomass fired chain grate steam boiler.
