Chuany, the robot manufacturer and automation system integrator from China, on showed solutions of stack mold cutlery packing and IML at Chinaplast 2025 with the injection molding machine from Union Plastic.

Starting from the distributing and installation service of injection molding machinery, Foshan Chuanyi Precision Machinery Co., Ltd. established in 2008 and have their own team of R&D for injection robot and automation solutions design. Chuany cutlery packing system was put on market on 2012, has their own mold making company in 2016 to provide clients a turn-key automation solution and start promoting of their IML system from 2017 in Chinaplas with the stack mold cutlery packing system since then.

As one of the automation integration company who has the capability to provide a turn-key solutions of injection molding, Foshan Chuanyi Precision Machinery Co., ltd. designated in the turn-key solutions of IML and cutlery packing to provide clients a ready to work system of the systems.

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.
