I would appreciate anyone who can help with managing all of the lines, hoses, etc. on a variety of size molding machines, in a neat fashion. Want to eliminate slip, trip fall and entanglement. Any suggestions?

Let me know when you find out an idea...

The best thing I have seen so far for keeping cooling lines, jumpers etc. neat in storage and transit for each mold is to coil up the lines and keep them in separate bags numbered with the mold number. Now for the molding machines, each machine may be a little different if you are using different brands, chillers and TCUs. Try to use the same layout for each machine. Mount manifolds on the back of the press with ball valves at every hose. You could also mount them in the press under the mold or on the platen if you have enough room. Have all the lines going to and from the manifolds/mold running inside the press. Each in and out is zip tied together in several places to keep the hoses organized. Tag the end of the hose with a number and tag the manifold valve with the same number. When a mold does not need as many cooling lines you simply shut them off at the ball valve and keep them tucked in the machine.

Chad's comments are excellent, and I agree with them; however, in shops that have many different molds, or molds that are used very infrequently, you may or may not want to have a set of individual hoses for each mold. One thing I have seen is a wheeled cart, similar in size to the kind of luggage cart you see in hotels, with a series of horizontal bars/racks at different heights. The longest hoses are hung over the top tier, with the shortest hoses hung on the bottom closest to the floor. For each mold, a color code or number code could be put by each fitting that corresponds to the length of hose needed for that fitting - the hoses would have the same color or number codes attached to them. Fittings should be standardized, but if this is neither possible nor practical, baskets can be hung on either end of the hose cart that hold different size fittings.

no simple solution but starting from the good samples are presented here you should look at a much bigger picture.
Can you arrange the molds of similar size in the same press? scheduling need to be more proactive to help reduce the variation to improve the overall set up.
If this is possible the lines will be then at standard length and is no need to have special set of hoses for each set up,(manifolds need to be mounted at each press at the same location- A and B side).
Shorter hoses will also reduce the quantity of tie them,and in some cases eliminate that step.
If you apply this method will reduce the necessity of special hoses and improve the set-up
Moving hoses ..from - to ..is a waste of time as you all know.If the standardization is possible you will reduce the hose consumption,and optimize the utilization.

Oscar I completely agree, and what you suggested is what I was referring to by mentioning the manifolds, running the hoses inside the press, and keeping the layouts the same for each machine. Set the machine up with the max # of hoses/manifolds you may need for the group of molds that run in that machine, and shut the 'extras' off with ball valves when not in use. It may cost more initially because of the # of hoses, but it will make things much easier in the long run.

What size machines are we dealing with?
What size molds?
Hot oil? water? Air? Oil for cores? mold temp controller cables? interface wiring?
For me this makes a difference in the answer.
