In the factory I work the wiring is bit old and loads of chocolate blocks connected in-between wiring, its both inside machines(die casting machines) and general wiring.

I have heard about soldering, crimps and plastic caps and using one single cable.

In places where I cant use one single wire I need to connect it with a type of connector, but is there any other option to replace these chocolate blocks which is better and good way of connecting two wires.

kind regards

I would consider using Wago connectors. They have been discussed on the electricians forum. Most wholesalers carry them.

Have you thought of using straight through crimp connectors?

I use these on a regular basis at work!

For all connection voltages, crimp connectors are often cited as best where the wiring may be subject to vibration, although there are some screw and screwless terminals with good vibration performance these days.

Soldering has had a bad press, particularly for power circuits (regardless of voltages), because the skill of soldering power cables has not been taught at all well (or even at all) in most industries for a number of years. I'm not sure about the performance of lead-free solder (which would almost certainly have to be used on new connections) over older leaded solder (where migration of tin away from lead caused joint failure/burning), but I do know that the surfaces to be soldered have to be meticulously clean with lead-free, or you might as well forget a good joint, and soldering temperatures are at least 60 degrees more with lead-free.
