Market Demand and Production Flexibility
Many plastic manufacturers aim to achieve greater flexibility with limited equipment. For producers of water tanks, road barrier, and other medium to large hollow products, using one blow molding machine for multiple products helps improve machine utilization and adapt to market changes.
With proper planning, a single blow molding machine can support the production of different plastic products while maintaining stable operation.
The Importance of Mold Change
Mold change is the key step when producing different products on the same machine. By installing molds with different structures and sizes, the machine can switch between products without replacing the entire system.
To ensure smooth changeover, molds must match the machine’s clamping structure, platen size, and extrusion configuration. A standardized mold change process helps reduce adjustment time and maintain consistent forming quality.
Pay Attention to Product Size Compatibility
Although one machine can run multiple molds, product size differences should not be excessive. Product capacity, mold height, and clamping dimensions must stay within the machine’s design range.
Large size differences increase setup complexity and may affect molding stability. Selecting products with similar dimensions and structures improves the success rate of mold changes and overall production stability.
Process Adjustment and Stable Operation
After mold change, process parameters usually need adjustment. Different products have different requirements for wall thickness distribution and cooling time.
A stable control system and practical experience help the machine reach stable operation more quickly after product changeover, ensuring consistent product quality.
