JH-Welltec Machine India Pvt. Ltd. On Show Their New Servo Machine SEII 380 In Chair Production without Robot

Abstract: In the demo show JH-WELLTEC Machine India Pvt. Ltd. chose a cold runner mold in production of the chair. The advantage of the cold runner mold is it's lower cost and easier for maintenance but will have a runner to be removed manually or automatically. In this show JH-WELLTEC Machine to have the chair free dropped and the runner removed manually. It's economic but not attracting to visitors in an exhibition.

JH-WELLTEC Machine India Pvt. Ltd. on show Welltec new injection molding machine SEII 380 in production of one cavity chair without robot picking in exhibition to show the capacity of the injection molding machine.

In the demo show JH-WELLTEC Machine India Pvt. Ltd. chose a cold runner mold in production of the chair. The advantage of the cold runner mold is it's lower cost and easier for maintenance but will have a runner to be removed manually or automatically. In this show JH-WELLTEC Machine to have the chair free dropped and the runner removed manually. It's economic but not attracting to visitors in an exhibition.

To provide customer with a more efficient turn-key injection automation solution, the better choice would be to have the injection molding machine equipped with a SWITEK 3 axis servo injection robot SW6712DS-20 which has a payload up to 8kg and could be easilly programmed with EOAT sets to remove the runner automatically.

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.
