To Reduce Mold Loading time, Let us discuss type of Mold Clamping Methods, For Big size molds above 2000T machine, suggest best way to clamp and methods available, thanks,

hi! Anandan,
there are many methods to reduce mould loading time ie. magnetic platen,hydraulic clampers,avoid the d shekels from eye bolts etc. that's are depends what system you fallow at present,and how much you plan to invest.

Best way is using magnetic platen. 

There are several methods. Engel has their hydraulic clamping method, magnetic plattens are great (we use Tecnomagnete and Staubli), as well as clamps.
For an easy quick mold change system, you should look at Lenzkes. They have a 'shoe' that is bolted to the platten, then you have a clamping 'arm' that slides into the 'shoe'. The 'arms' are available in several styles for different clamping plate thickness, and longer 'arms' for more reach to the mold clamping plates. Only downside is the clamping plates should be close to the same width so the 'shoes' can remain in place without moving them.
One other great method not used too often: Through holes in the mold clamping plates, for the bolts to screw directly into the platten hole. This removes alignment issues if using automation. It also negates poor hand clamping as a bolt through the plate can still support a mold without being torqued down. I worked at a shop that used this for the older machines. The bolt holes can be slots if the hole locations change so much between frame sizes. Give it a try, you may like it!

You might like to look at how long it takes to actually mount the mould against how long it takes to connect the water, electrics and hydraulics to the mould. I would guess the connections take the bulk of the time. Look at Staubli, Enerpac and others for quick connection solutions, they could give you a better ROI than the automatic clamping systems.

I use to build standardized clamp plates that drop in a mounted shoe. Along with water manifolds and common electrical locations it can really speed things up. It can look a little funny for smaller mold, but works very well.

there are quick mold change devices are available,that will take hardely 5 minutes to change the mold,no nut bolt,only by haudraulic clamps according to mold load.
