Union Plastic on show ES380 high speed all electric injection molding machine with turn-key IML solutions of 8 cavities cups at Chinaplas 2025. Which is intending to provide clients a ready to work system of food package IML production.

The IML robot in the show is a side entry IML solution with model number TSER ULTRA 20 which is a high speed IML robot with a 12 cavities magazine and EOAT sets for the production of IML Yogurt cups, which is now a budget smart solutions of Yogurt cups IML production. And for bulk production of the IML Yogurt cups, a vision control unit and a packing unit would be integrated to produce an IML cups free from Biotic pollution.

Founded in 1984, Taiwan Union Plastics Group (T.U.P) is one of the earliest manufacturer of injection molding machines in China, the brand was transfered to HongZhen Liansu Machinery Co., Ltd. in 2019 and has the headquarter moved to HangZhou, ZheJiang Province of China with a full range of injection molding machine products which include:

• UN Series M7 Servo Plastic Injection Molding Machine
• ES Series Full Electric Injection Molding Machine
• HS Series Two Platen Injection Molding Machines
• HD Series Multi Components Injection Molding Machines

With a production base up to 67,000m² and more than 500 employees, Uniio Plastic is designed to provide culients with a high quality injection molding machine of cutting edge technilogy together with excellent service.

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.
