History

Flanges were invented in 1958 by Logan Maurus initially under the Ty-Rap brand by Thomas & Betts Electric Company . They were designed for aircraft wire harnesses. The original design consisted of a metal ratchet, later it was changed to nylon and plastic .

characteristics

Cable ties are manufactured in different lengths and widths to cover a wide range of diameters and clamping forces. The length depends on the diameter to be embraced and the width of the resistance that it has to support. They can be manufactured for special conditions such as radiation resistant, high temperature with extra flame retardants.

Applications

The function of the cable ties is to clamp, join or fasten cable harnesses, pipes or any other element. The Flanges are also known as clips, belts, hoses or belts. Flanges or clamps are used in a wide range of industrial sectors: packaging, automotive, petrochemical, food, agriculture, fish farms, lighting, electrical installations. They are placed by hand, but, for the final placement of the flanges, there are tools that allow for precision pressing and cutting.

Flange types

Reusable flanges: They are placed in the same way as standard flanges, but can be reused, using the reopening system available. To uncouple the recoverable cable ties, the release tab is pressed in and out of the head, and can be reused. They leave no residue.
Color flanges: special for playgrounds
Flanges with labels: They can be marked with an indelible marker or by sticking a label. Special safety flanges marked with logo and numbering can be made.
Ratten flanges: These flanges are especially indicated for closing plastic bags, where it is necessary to open and close repeatedly. In gardening and agriculture they are used for placement of guardians,
Playground bridles: Bridles specially designed for use in playgrounds. Its flat head prevents bumps and scratches. They are used in ball parks, to hold the cups. Its width prevents damage to the mount and the head design, which does not protrude like standard flanges, prevents children from hurting themselves.

Thomas and Betts flanges: its fixing system, which is made by means of the 316 stainless steel metallic tongue that is anchored on the body of the flange. This system is stronger and more durable, and resistant to corrosion.

Manual boats: Designed for the placement of labels, on products such as shoes, clothing, etc.

Determination of the tension for the flanges

So far there is no applicable or established test on the market. Hellermann Tyton group companiesThey work with a usual dynamometer with a minimum test frequency of 10,000 Hz to determine the tension forces of the flange tools and to guarantee the quality of tying of the tools. These tools are more difficult to test than meets the eye. The important thing is to be able to comply with a standardized procedure, always adapting the same necessary test conditions. This means, for example, the size and thickness of the flange, as well as its water content. Testing using different flanges and / or different conditions can easily lead to very different results. Usually the cutting speed, the position of the tool with respect to the flange, the wear conditions of the tools and the condition of the flange, they play a fundamental role in determining the tensile forces.

Flange Pull Force Formula Accordingly, we must point out that the values we offer can only be considered as guidelines for your information. Values cannot be transferred to practice as “exact value”. In our user instructions we specify a range of settings for each flange. If the voltage values must be documented or must comply with a specification, we recommend the help of a meter or dynamometer. Just to help, use half the Minimum Tension Force as the tension force. Values cannot be transferred to practice as “exact value”.

Optimal storage conditions for flanges

Always store flanges in airtight plastic bags made of polyethylene. Once opened, use the zip ties as soon as possible.
Store them away from heat sources. Do not leave them, for example, on top of a radiator
Do not expose the flanges to sunlight. Do not leave them, for example, on a window sill.
The ideal storage conditions for flanges are those of the central European climate
