Stack mold is a popular solution of house hold products because it can maximize the productivity of the injection molding machine. But among the producers of the cutlery the stack mold is not popular, why and what's the advantages and disadvantages of the stack molds solutions for cutlery production?

The advantage of the stack mold solutions is the productivity of the system. As show on the stack mold solutions above that it's possible to produce 48 pcs of spoons or forks and have them well box packed in about 10s by a 280T injection molding machine (Which is a special injection molding machine designed by WEIDA machinery for the stack mold production, the nozzle of the injection molding machine is installed to the top of the injection molding machine) while would be possible to have a maximum of 32 cavities mold design by with a standard mold design.

Against the advantage of the stack mold solution, the disadvantages of the system is also obvious:

• The Cost of the System: Not only the cost of the mold, a stack mold solution will also increase the cost of the automation system and a much larger floor space for the installation of the cutlery packing system.
• The Difficulty of the Maintenance: The maintenance of the stack mold cutlery production system would be much more complex, the producer must have the capacity to do the maintenance of both the stack mold and the auto-packing system for the stack mold. It woudl be a big challenge to most of the small and medium sized producer of the cutlery producers.
• New Mold Technology Provide More Economic Alternative Solutions: Instead of a stack mold solution, a vertical 24+24 cavities single mold solution will provide a counter productivity of the cutlery but much lower cost of investment in both the mold and automation system.

Anyway, cutlery packing system is systematic integration of the injection molding machine, the mold design and automation system design, the best way would be to contact Adams from SWITEK for a turn-key solution of the cutlery to get a ready to work cutlery packing system.
