Shiny white metal which is light, ductile and malleable and which changes little when exposed to the air. Its lightness means it is ideal for use in the automotive industry, aeronautics, industry, construction and decoration.
Depending on requirements, TF offers various assembly techniques: crimping, seaming, riveting, welding, etc.
Bending is carried out with the help of two tools of opposite shapes: a pointed punch and a hollow die. Two different techniques are used depending on the thickness of the metal, the length of the bend, the resistance of the material and the shape of the V. Air bending allows different angles to be created with the same tools. Bottoming uses two dies and two different punches for two different angles. It provides greater accuracy for thin metal sheets.
Brushing is a mechanical operation which results in light, long thin streaks on the surface of the material.
Mechanical treatment on stainless steel which gives a material a polished appearance. Brushed stainless steel is mainly used in the agro-food industry, domestic appliances, paramedical sector, etc.
Cataphoresis or cationic electroplating is an industrial painting technique. The workpiece, acting as a cathode (hence the name cataphoresis), is immersed in a bath of water-soluble paint. The paint particles in suspension in the bath migrate by using an electrical current, from the anode to the cathode. The paint particles are thereby evenly deposited across the whole surface of the immersed workpiece.
TF has had ISO 9001 version 2000 certification since 2002
Clinching is a mechanical technique for assembling metal sheets. The basic principle is to connect two metal sheets by drawing them between a punch and a die. The sheet sustains a local plastic cold deformation, forming a permanent connection.
Crimping is a simple operation for assembling two cylindrical workpieces. Like clinching, this technique involves the cold plastic deformation of the material without it being crushed.
Grinding is a process used to remove material to shape and smooth the appearance of the sheet metal by polishing the welded seams using abrasives.
Hot galvanising is a technique used to protect a steel part though a layer of zinc. This process helps to prevent corrosion.
Knurling consists in creating distortions (grooves, ridges and raised edges) on the surface of a cylindrical workpiece.
Laser cutting uses radiant energy in the form of a light beam. The absorption of this energy by the workpiece at a precise point, less than 1 mm², causes the material to fuse/vaporise. The vapours and liquefied elements are ejected by an additional blast of gas. Laser cutting is suitable for all steel, stainless steel and aluminium sheets (depending on the thickness).
MIG-MAG welding is a semi-automatic welding process. The fusion of the metals is obtained as a result of the heat energy given off by an electric arc produced in a shielding gas between an electrode wire and the workpieces to assemble.
Nibbling is a repetitive cutting technique which uses a succession of juxtaposed punches to form the desired cut.
Passivation is the electrochemical treatment of metal or alloys to slow down corrosion. In most cases, this passive film appears spontaneously through oxidation. This technique bleaches the aspect of the metal and gives it back its original characteristics by stripping the TIG welding.
Depending on the desired aspect, TF offers all types of paint with various finishes - polished, satin, etc.
The stripping of a steel surface with the help of a hot diluted solution of phosphoric acid causes the formation of iron phosphate, which causes passivation and improves the resistance to corrosion.
Piercing is a cutting process using shearing tools: the workpiece is cut out as the two blades of the punch and the die cross over each other.
Polishing is a mechanical or chemical operation which gives the material a shiny, even appearance.
Rolling is a forming process in which the sheet is passed through 3 or 4 rolls. Numerical control enables us to produce complex shapes such as ovals, oblongs which are reproducible in serial production.
Sanding strips the raw metal sheet in order to obtain a smooth surface. This process also improves the metal’s adherence.
These are surface cleaning techniques which use an abrasive projected at high speed using compressed air through a nozzle, onto the material to strip in order to smooth the material or to enhance the grip of the metal sheet for better paint adherence.
Seaming is achieved through a combination of folds and interlocking which enable metal sheets to be assembled along the resulting joint.
Through its catalogue, TF can guide you in the design of your products and presents most of the manufacturing processes and techniques.
Technique for cutting out workpieces. Separation of workpieces into 2 by passing them between 2 blades (1 fixed, 1 mobile) which cross over each other.
A grey, hard metal which is an alloy of iron and carbon. It comes in different forms: mild steel, stainless steel, etc.
TIG welding is a welding technique using a non-consumable electrode. TIG is an acronym of Tungsten Inert Gas where Tungsten refers to the electrode and Inert Gas is the type of plasma gas used. The arc is created between the non-consumable electrode and the workpiece under a gas stream. Generally, it is an inert gas or gas mixture.
Electrical spot welding is a process to assemble two parts between two cooled copper electrodes. When the low voltage current passes, a Joule heating effect is generated at the centre of the electrodes. As the resistance of the electrode-workpiece contact is as low as possible, the maximum heat is produced where the parts are in contact causing a drop of liquid metal to form, held in place through the pressure exerted by the electrodes.
Welding technique to join two fine metal sheets.
