Haitian on show their 5^th generation of JUPITER Series two-platen injection molding machine JU5500/3450 with turn-key solutions of buckets production at PlastImagen 2025, the largest exhibition of injection molding machinery in Mexico city.

SPECIFICATION of JU5500/3450

Features of Haitian JUPITER Series Injection Molding Machine JU5 Series two-platen injection molding machine is equipped with flexible open integration functions, and the entire series is equipped with "Go Factory 2.0" digital intelligent management software, whcih can best meet customers' one-stop demands for automated and digitally intelligent production.
In addition, it can be compatible with the latest international general interfaces according to needs. Customers can freely choose automation integration enquipment and MES partners to realize interactive connections between multi-device and multi-platform systems with injection molding machines as the core, and enjoy open integration.
As a two-platen injection molding machine, it's best suitable for the production of:

• Plastic parts for the automobile manufacturing industry
• Plastic parducts in large housold appliances industry
• Plastic products with heavy mass and large projected area require large clamping force and large internal distance between the rods
• The production of ultralarge plastic parts

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.
