Union Plastic on show ES380 high speed all electric injection molding machine with turn-key IML solutions of 8 cavities cups at Chinaplas 2025. Which is intending to provide clients a ready to work system of food package IML production.

The IML robot in the show is a side entry IML solution with model number TSER ULTRA 20 which is a high speed IML robot with a 12 cavities magazine and EOAT sets for the production of IML Yogurt cups, which is now a budget smart solutions of Yogurt cups IML production. And for bulk production of the IML Yogurt cups, a vision control unit and a packing unit would be integrated to produce an IML cups free from Biotic pollution.

Founded in 1984, Taiwan Union Plastics Group (T.U.P) is one of the earliest manufacturer of injection molding machines in China, the brand was transfered to HongZhen Liansu Machinery Co., Ltd. in 2019 and has the headquarter moved to HangZhou, ZheJiang Province of China with a full range of injection molding machine products which include:

• UN Series M7 Servo Plastic Injection Molding Machine
• ES Series Full Electric Injection Molding Machine
• HS Series Two Platen Injection Molding Machines
• HD Series Multi Components Injection Molding Machines

With a production base up to 67,000m² and more than 500 employees, Uniio Plastic is designed to provide culients with a high quality injection molding machine of cutting edge technilogy together with excellent service.

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.
