From IML to packing, acmeplas automation on show turn-key solutions of 16 cavities IML cups injection molding at Chinaplas 2025 with Systec 420, the high speed injection molding machine produced by Sumitomo Demag.

With the popularity of Yogurt in China, the producers of IML containers for Yogurt are pursuming solutions of IML with more cavities for a higher productivities to win out in this mostly competitive market in China. An IML system of 16 cavities would be a challenge to both the hotrunners balance of the mould and the labeling stablity of the IML robot but would be an economic configuration for an IML system with vision control and packing system, which will help to maximize the production capacity of the two units.

With System 420, the high speed injection molding machine produced by Sumitomo Demag, it'll provide a stable injection molding with a minimal cycle of around 6s to ensure the productivities of the IML system.

Any way, an IML system of 16 cavities with vision control and packing will only be suitable for the none stopping production of the IML containers with single size and style. For small and medium sized producers of IML containers, an IML robot with a fast changeable magazine and EOAT would be a better solutions for the fast changing marketing.

For PVC/PPR pipe fittings with nuts with a diameter of around φ25mm most of the producer will choose an injection molding machine of around 250T and a mold cavities of 8 Cavities, will a more cavities mold design with a larger injection molding machine a better choice for pipe fittings producers?

8 Cavities Pipe Fittings Nut Insertion Automation Solution

According to the experience of working with LESSO group in the automiztion of their PVC/PPR pipe fittings injection production system, we finally decide to have an 8 cavities mold deisgn with 250T injection molding machine because:

• A 250T injection molding machine with 8 cavities mold design is an economic investment to start up a pipe fittings injection production system.
• For a pipe fittings auto-injection production system with nut insertion, the weight of the EOAT would be very heavy. An eight cavities solution will perfectly balance the payload of the injection robot and weight of the EOAT.
• An 8 cavities layout design of the pipe fittings will produce a better mold flow during the injection production of the pipe fittings.

Anyway, to upgrade your PVC/PPR pipe fittings injection molding system you must keep in mind that it's only valuable to have an automation system for bulk production products, which means that one injection molding machine with only one mold to be equipped with one automation system for the pipe fittings' Nut insertion, runner cutting and parts picking.
