Sumitomo (SHI) Demag demonstrated their new hybrid injection molding machine EL-Exis SP 250-920 with a fast cycle 4 cavities butter box IML packaging production.

As one of the fastest hybrid injection molding machine available in the world designed for the thin-wall containers, it's one of the best injection molding machine for IML Solutions with SWITEK IML Robot SW833-19 and the high speed injection molding machine SW7112DS for the pick and place of the other thin-wall containers.

Why is 8 Cavities Mold Design the Best Solution for Elbow with Nuts?

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.
