Entech Engineering produces a comprehensive range of tube expanding and reducing tooling (specialists and industrial standard.) A large range of sizes are ex-stock for next day delivery. All made to the highest quality and at remarkably low prices. High-powered machines at low cost also available.

The multiform ET76 can either expand or reduce the ends of tubes. Up to 76mm diameter using standard tooling and 150mm diameter using non-standard tooling. Another function of the machine is the facility to put ribs or dimples near the end of the tube.

This type of machine has many advantages over the 'ram type' tube end-former:

1. A minimum number of tools required, as the adjustment is variable.

2. Clamp dies are not required, enabling short lenghs of tube to be formed with less wastage.

3. It is possible to expand or reduce on or close to a bend because it is not necessary to grip the tube.

Average machine cycle time is 3 1/2 seconds, with the changeover time between expanding and reducing tooling taking approximately 30 seconds. With our 'drop in' tooling, various sizes of tooling can be changed quickly resulting in minimum 'down time' there by increasing productivity. Attached to the machine is a footswitch controlling the operation cycle. This leaves both hands of the operator free to handle the component.

We manufacture a wide range of tooling for the manipulation industry. The following are a few examples:

• Tube profile checking fixtures.
• Leak test fixtures
• End spinning tools
• Rotary out feed
• Exhaust box and seam tooling
• I/O expanding and reducing tools
