Spectex 2015 Expo

We stopped in to check out the SPECTEX 2015 show, held at the Melbourne Convention and Exhibition Centre recently.

We were keen to check out the new stationary welder from Leister, the SEAMTEK 36. We were impressed with how versatile the machine’s settings are, with control over the individual rollers, and a memory bank to store commonly used configurations.

The SEAMTEK 36 is ideal for workshop-based continuous seam welds in polyethylene, PVC and other thermoplastic textiles.

Welding at the Rolex Learning Centre

This architect-designed building for a polytechnic university in Switzerland resembles a slice of of Swiss cheese! And with no straight or flat lines, it proved a challenge to the contractors waterproofing the roofing membrane.

A range of Leister equipment was used to weld this 1.8mm thick PVC membrane, from the Varimat V for long weld seams, and even the little Hot Jet S to weld the challenging hard-to-reach pieces.

Polyweld supplies the full range of Leister hand held hot air tools and automatic seam welders. Call us on (08) 9303 2164 or visit

World’s most precise plastic weld

A university in the UK claims it has produced the world’s most precise plastic weld, using lasers.

Laser has been used for some time now in plastic welding very small plastic components (LEISTER has an entire laser welding division). What the researchers at Cambridge have done is taken the infrared technology even smaller, to be able to weld plastic with widths of 1µm and channels of 5µm. Now that is seriously small!

Precision is generally operator dependent (skill and practice!) – but it also helps to have the right gear. See Leister’s entire plastic welding range at Polyweld Machinery.
