After years of market study on the demands of the South African signage industry and successful distribution of the V3 channel letter bending machine, Exion Corporation has exclusively introduced the TPS fully automatic channel letter bending machines into the South African market. This article appears in the latest Sign Africa Journal.
TPS is a Chinese company specialising in channel letter bending machines and has sold over 1300 of them all over the world in the past 13 years. They are well established and popular in the European and North American markets. For example, Gemini Signs, one of the biggest signage manufacturers in the USA, is equipped with eight TPS channel letter bending machines.
Exion Corporation’s MD Jay Kim explained, ‘The strong points of TPS machines are the beautiful finishing and the fact that some of the world’s best parts are installed in the hardware point. However, the stronger points lie in their software. Firstly, many employees with PhDs are involved in the software development division to keep upgrading the software. Secondly, it is easy to set up parameters defined on materials. In comparison, with other companies’ machines, specialised engineers must come to change the parameters every time the material is changed, which means extra time and expenditure. Thirdly, it is user friendly and you need just half a day’s training. And whatever material you use, you are getting perfectly accurate output because of the software.’
The TPS machines can bend aluminium, stainless steel, and galvanised iron. The minimum bending radius is 7mm in stainless steel and 20mm in aluminium return. The height of the return can be from 20mm to 180mm, which can bend very small to big letters more than two metres high.
‘I have crosschecked TPS with its European and American clients and they said that it is not an ordinary Chinese company. TPS is professional and their clients are happy, not only with their products but also with their after sales support,’ added Kim.
TPS machines feature a front feeding straightening mechanism, clamping alternating conveying mechanism and slotting mechanism. It has a built-in high-performance eight axis motion control card. The intelligent bending software programme ensures forming precision. The equipment also features a multi layer super-long guide rack.
The bending tool quick-change system ensures fast changes between plate metal material and aluminium profiles. This means that multiple materials can be bent accurately and with no damage by the same equipment.
The tool rod bending system features a single set of bending tool rods that work for both aluminium profiles and plate material. The fixed base for the computer monitor allows operators to adjust the screen position and angle that is best for them.
A front feeding straightening mechanism straightens curved materials in advance during material handling to ensure that these materials dont get stuck during processing.
Closed-loop control using alternating clamp feeding with the unique full closed-loop detection provides real-time compensation for length deviations such as the slippage of detected materials to avoid inaccurate letter length, or inaccurate matching with panel letters.
The bending stress database allows users to adjust bending pressure quickly and easily according to different materials. Users can select the corresponding material from the database when they want to change to another material. This avoids a cumbersome re-adjusting process.
Plate bending tensile intelligent compensation: deformation of materials during the bending process will affect the length of the formed letter, reducing letter matching precision of the shell and panel. TPS software provides intelligent compensation caused by the length deviation, to ensure bending accuracy.
