WELLTEC Machinery injection molding machine custom made for PVC plasticising installed for the production of PVC pipe fitting without robot and automation application.

PVC pipe fittings are a very important material in mumicipal and real estate construction, and the production of PVC pipe fittings will need special injection molding machine with special screw and plasticising unit. With more than 20 years experience in the production of injection modling machine for PVC injection, Welltec machinery is king in providing solutions for PVC pipe fittings solutions.

It's a trend globally that the cost of manhour is getting higher and especially the youngs are unwilling to work in injection workshop because of the harsh working environment. To increase the productivity of the pipe fittings, LESSO group starting it's automatize of their pipe fittings production which include the in mold insertion of the metal parts, the parts picking and runner cutting. With the Pipe Fittings Automation Solutions provided by SWITEK, LESSO group is expected to reduce 1/3 of man hours and increase 20% of the productivity.

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.
