Lubricant for hot forging FAQ

How should I handle the recovered liquid (lubricants)?

Because containing a high portion of oil content and sludge in the recovered liquid, remove them and control concentration with densitometer.

What methods can be used to reduce mold build up?

One method is to change to lubricants for build up property or adjust dilution ratio properly.

What kind of method of handling the trouble like chipping?

Select products with higher lubricity to improve formability.
Or by changing to products with low build up property may solve the problem.

What problems might occur if the dilution factor of the mold releasing lubricants is too low?

Generating mold build up might cause chipping or operation failure by build up in the peripheral equipment of forging machines.

What problems might occur if the dilution factor of the mold releasing lubricants is too high?

Releasing performance of products might be worsen and cause soldering or chipping.
There is some case of creating distorted products due to removing from the mold forcibly.
