Chinaplas 2025, QingDao Sarlwer Automation on show turn-key solutions of 4 Cavities 1L IML buckets production with both side entry and top entry IML robot. Unlike the other exhibition of cooperation with other injection molding machine manufacturer, Sarlwer Automation have an own brand injection molding machine SW458 to finish the injection molding process.

As one of the economic IML solutions provider in China, Sarlwer Automation put on market a series of IML robot for different IML containers, mainly top entry and side entry IMl robot for the medium and large size containers like paint buckets.

On show a turn-key solutions of IML is a trend among the IML solutions providers which will provide the customer with a ready to work IML system and free from the disputes among the suppliers of injection molding machine, the mold and the IML robots. As the system intgerator of the IML solutions, it's no doubt that the R&D team of Serlwer Automation would be more professional than the purchasing team of the buyer and has a better understanding of the China injection machinery producers.

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.
