Noticed that the medical market is growing significantly, Sumitomo (SHI) Demag is upgrading their electric injection moldign system for the challenging of a rapid rise of electric injection molulding machines demand in the market for the next few years, and enhancing trust with customers amid epidemic prevention and control.

Targeted the carbon peaking and carbon neutrality gaoals which are popular concepts around the world and a massive energy transition is underway, Mr. Scattarreggia estimated that the market share of electric injection molding machines and hydraulic machines will reach 50%:50% by 2030.

Mr. Scattareggia think that conpared to the hydraulic injection molding machine, the electric injection molding machine is not only has a much better energey cost, but also higher product stability and better production efficiency, which will enable the customer to achieve higher profitability.

Because of the stability and precise dimensions of their shot weight, the main markets for electric injection moulding system were concentrated to IT or electronic applications, but growing fast in the medical field and automotive industry.

For the new growing market, Sumitomo (SHI) Demag lineup its first all-electric machine PAC-E which is a new all-electric, high - speed injection molding machine engineered specificall for manufacturers of beverage closures and thin-walled packaging applications with a clamping force of 350T at K2022.

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.
