In the hardware tool industry, the demand for blow molding machine equipment is growing day by day.
The “White Paper on the Development of China’s Plastic Machinery Industry in 2025” shows that the annual demand for blow molded products such as hollow tool boxes and bags in the hardware tool manufacturing industry has grown by 12%, but 35% of companies face pain points such as insufficient equipment customization and adaptation and incomplete supporting services.
When most hardware tool companies produce tool boxes, the existing equipment cannot meet the molding needs of special sizes and structures. The trial mold cost is high and the cycle is long, which restricts the speed of new products to market.
