PRECISION BORE TUBING MACHINES

PRECISION BORE TUBING MACHINES

This equipment produces precision bore tubing by heating a glass tube and sucking it on a precision stainless steel mandrel.

The machine is provided fully equipped with the flame heating system, the tool holding system, the nitrogen flushing, the tube holder …

The profiling process if fully automated but the loading/unloading must be done by the operator. The operator controls the machine and the parameters of the recipe through an HMI.

There are two heating systems on the machine :

– burners heating the glass tube (may be only 2 or 3 for small tubes)

– An induction oven preheating the mandrel before the glass tube is sucked on it.

This combination provides the following advantages :

– A better control of the T° of the mandrel and consequently the accuracy of the precision bore tubing.

– It increases the speed of the process (as the mandrel is preheated). Calibrating a 1.5m tube can be done under 15 minutes (depending on the tube diameter and thickness).

– It makes the unmolding of the tube a lot easier.
