OPT, the brand originated at year 1983 in Germany and entered China in 2013 who is designated to make the assembly of the robotic arms EOAT as easy a play a LEGO, on showed their solutions of robotic arms EOAT at Chinaplas 2025.

With a unique modular system developed by OPT automation, the projector can assemble their own gripper solution with perfect precision with the spare parts produced by OPT which include low density and lightweight carbon fibre material of high bending strength, shear strength and tension strength.

Not only the supply of standard parts for the assembly of robotic arms EOAT, OPT automation will also provide customization service for the special EOAT parts for individual special constructions of gripping parts. The projector can combine the standard parts of OPT with special parts and individual products to create special solutions.

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.
