TOYO on show their new all electric injection molding machine SI-230-7GS with turn-key solutions of lock-box injection molding and have the box and lid picked by a Runma high speed 3 axis servo injection robot at PlastImagen 2025.

TOYO SI-230-7GS is the 7^th all electric injection molding machine with clamping force 2300kN and optional injection speed from 200mm/s ~ 500mm/s for the precise injection of thick wall parts or high speed injection of the thin-wall containers. The solution on show PlastImagen 2025 is a turn-key solution of Lock-Lock box which has the box and lid of the box integrated into one mold. The advantage of this design is that it will ensure the same parameters of box and lid injection and ensure a perfect match of them.

In the show of PlastImagen 2025 TOYO chose to have the box and lid picked with a Rumma high speed 3 axis servo injection robot. With a mold which integrated the box and lid the producer of the Lock-Lock and easily upgrad it to an automation system of which chan either stack the box and lids to have them packed in bundle or have the box and lid locked automatically and packed as one set.

The more rewarding investment would be to have the TOYO SI-230-7GS equipped with a G370F or FH400F injection unit to increase the injection speed of it up to 330/500 mm/s as a high speed all electric injection molding machine to work with SWITEK SW8 series high speed IML robot for the production of small size IML Yogurt cups. With an injection unit of FH400F the TOYO SI-230-7GS + SWITEK SW8 IML robot combination is possible to work in a total cycle time of around 5s, which would be a rewarding investment to the producer of the IML Yogurt cups.

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.

For any other question about a PVC/PPR pipe fittings auto-production system please contact Adams from SWITEK for a turn-key solutions of pipe fittings production.
