The production of plastic flower pots is a game of speed, durability, and process control. In this application, everything revolves around high volumes at the lowest possible cost per unit. At the same time, the end product must be consistently high quality: pots must be sturdy, dimensionally stable, and visually appealing – especially for consumer products. They must stack well, include drainage holes, and withstand transport and various (outdoor) conditions. A key feature of flower pot production is the use of recycled materials. This demands a machine that can handle fluctuations in melt quality and MFI (Melt Flow Index) without causing inconsistencies in wall thickness or product shape. A stable plasticizing process and reliable injection are crucial, especially for deep pot designs or high-cavity moulds.
Part removal must be smooth and controlled – delays or blockages in the cycle lead directly to production downtime. Moreover, flower pots are often produced in multi-cavity or stack moulds, requiring a powerful machine setup and precise clamping force distribution to ensure consistent quality across all parts. The visual finish – color, surface texture, and wall thickness – must remain uniform, even during long production runs. Process stability plays a key role here.
