Sheet metal edge trimming power tools can be used to deburr the edges of metals and plastics - or to prepare these edges for welding - five times faster than angle grinders

Trumpf TKA 300/500 series edge trimmers can be used to deburr the edges of steel sheet metal, non-ferrous metal and superior quality plastics or to prepare these edges for welding. Compared to angle grinders, these tools work five to ten times faster on average. TKA 300 and 500 model edge trimmers are used to produce final edges in sheets that are clean, deburred and oxide-free.

This is required to eliminate the risk of injury caused by burrs in carriers and other accessible metal parts for example.

It is likewise important to prepare edges for welding and round off or chamfer housing panels for a more pleasing visual impression.

Companies that work with plastic also choose edge trimmers for deburring.

In contrast to angle grinders, edge trimmers only need to be passed along the edge once to obtain perfect quality.

No reworking is required for either straight or rounded edges.
This fundamental difference means that the worktime is five or ten times shorter as a rule.

The Trumpf TKA tools likewise eliminate the disadvantages associated with angle grinders such as heavy sparking and excessive dust.

Moreover, angle grinders are very bad at processing non-ferrous metals and plastics because these materials soon clog the pores of the grinding disks.

In the case of all these materials and a wide variety of steel grades, the Trumpf TKA 300 and 500 edge trimmers achieve excellent surface quality with rapid feed rates of 4 to 6m/min.

The compact trimming head of these models ensures that small radii and inner contours are processed effectively.

Users can choose between two edge trimmer models: The TKA 300 with an 850W drive unit and the TKA 500 with 1,400W of power.

The primary difference between the models in practice is the bevel height.

While the TKA 300 can trim bevels up to 2.2mm high and 3mm long in 400N/mm2 steel, the more powerful TKA 500 produces bevels up to 3.5mm high and 5mm long in the same material.

Thanks to moderate weights of 3kg (TKA 300) and 3.5kg (TKA 500), these tools are pleasant to use and the operators can work with them for long periods of time without suffering from fatigue.

* About the Power Tools business division of Trumpf - sheet metal processing power tools have a long tradition at Trumpf.

As early as 1934 the company from Ditzingen, Germany, presented the first motorized handheld shears for cutting sheet metal, thereby laying the foundation for the entire corporate group's 'sheet metal competence'.

Ever since, the sheet metal specialists have been constantly developing professional power tools - in addition to stationary machines for punching and forming, laser processing and bending - and as leaders of innovation they have set the pace in this area as well for changing market requirements.

During fiscal year 2005/06 the Power Tools business division of Trumpf, which has had its headquarters in Gruesch, Switzerland, since 1980, recorded EUR 72 million in sales revenue with 255 employees.

The current product range includes power tools for cutting and connecting sheet metal and for forming welding edges.

Sealing, gripping and motion control are typical performance features of Rubber Industries' custom rubber mouldings bonded to metal components

Rubber Industries provides these performance features in prototype through large volume quantities using injection, transfer, compression molding and LIM (liquid injection moulding) processes. Rubber Industries offers over 35 years experience bonding custom elastomer formulations to a broad range of substrates including aluminium, brass, steel, and plastic to suit customer design needs.

Its engineers understand the relationship between rubber elastomers, substrates, plastics and adhesives to determine the ideal process that results in a bonded assembly with cost-effective, high-performance features.

Rubber Industries offers a full range of custom formulated materials and hundreds of standard materials, to meet correct functional, environmental and colour requirements of the bonded assembly.

Virtually any application requirement can be met with this vast amount of formulations, including resistance to heat, cold, oil, gas and harsh chemicals.

Specific performance requirements such as hardness, fluid resistance, abrasion resistance, shrinkage, elongation, modulus and cost are addressed by Rubber Industries for specific rubber-to-metal and plastic bonding applications.

Rubber Industries has complete in-house capabilities for turnkey rubber-to-metal bonding including design assistance, tool design and building, prototype moulding, production moulding, deflashing, and packaging.

All Rubber Industries processes are optimised lead times which produce fast turnaround.

Impress an international canmaker and the second largest European supplier of food cans, has installed a new CTP system at its Norwich (UK) site

Impress was looking for a digital colour proofing system that could link to its workflow. When it came to printing on metal, however, the company questioned whether a colour print could serve as a colour-matched proof. The company was already using Agfa's ApogeeX as its workflow system, so Impress put the Agfa Grand Sherpa to the test to produce a paper proof suitable for matching colour for metal packaging.

According to Agfa, the Grand Sherpa rose to the challenge, enabling Impress to obtain a complete contract proofing system for metal printing.
