The new automation systems for the auto-production of ball vales of varies size is assembling and tested in the workshop of GuangDong Switek Technology Co., Ltd., of which will help the producers of PVC/PPR ball valves reduce the man hours andd increase the productivity.

The automation systems under go assembly and testing are solutions for the produciton of ball valves with both male and female nuts of varies size to be used in the drainage system. With a custom made 3 axis servo injection robot and end of arm tooling, the automation system will finish the production process of O ring/Core sorting, layout, inserting, parts picking, runner cutting and handle turning.

Since the first automation system of in mold insertion for pipe fittings production delivered in 2015, SWITEK R&D team developed a series of custom made automation system which include PVC pipe fittings runner cutting, PVC/PPR pipe fittings brass in mold insertion and runner cutting, faucet mandrel in mold insertion and runner cutting solution, ball valve core and O ring in mold insertion and runner cutting solutions etc. to provide the producer of pipe fittings a turn-key solutions of injection automation.

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.
