Other Details

Our Automatic Vials Making Machine (Type R3S) has been designed to eliminate the shortcomings and intricacies previously encountered in the manufacture of necked and screw neck vials from glass tubing. These are manufactured with glass tubing and widely used for various industrial applications.

The characteristics of R3S manufacturing method:

The full-length cane of glass is not cut into double pieces

Continuous shaping, without cutting, beginning at one end and finishing at the other are executed

It is fused off from the cane of tubing and the bottom sealed simultaneously according to the length of vial

The canes of glass tubing are not rotated on rollers

No change in the positions of the Ferguson Cam drive due to indexing

Construction & Operation:

The machine consists of two sections A and B which operate in synchronism and are erected on a common framework

The vial necks are formed in section A while, the bottoms on Section B

Section A is equipped with 12 chucks that are positioned in a circle and passes stepwise around a central axis

These chucks receive the full-length canes of glass tubing and carry these through the various operating stations that are necessary for forming the neck

After required preheating, the desired shape of neck or screw neck is formed at the lower end of the cane

This occurs at two stations, a pre-forming initial position and a final forming position. The cane is moved with the shaped neck downwards until it reaches the position where it drops onto an adjustable stop, which governs the length of the vial

Subsequently, while being heated, the formed piece of tubing is drawn down of the sealing off station by means of jaws from below, while the bottom is being formed

This occurs at the tangential point of inter-section between section A and B, so that the chucks pass the vials through the operating stations in section B to permit the bottom to be formed

The chucks in section A move the canes to a burner which opens the bottom which has been formed during the sealing off process and then through the operating stations for forming the vial neck
