GEDORE Manufacturing process for 8250 Combination Pliers (1) Blank cropped to size from C50 hardened and tempered steel. (2) Hot forged in the double forging die. The excess burr is removed under an eccentric press. (3) The blanks are normalised to obtain an even finer-grain more uniform structure with optimum strength. After descaling the blanks are calibrated for the following work steps. (4) The head is machined in a CNC-controlled machining centre. The rivet hole is drilled and counter-bored. The joint clearance and the outer contour are milled. The geometry of the joint area and the coarse and fine toothing are broached. (5) The joint faces are precision milled. The pliers head takes on its final form. (6) The moving and fixed pliers legs are riveted together. A smooth-moving joint with no play is the essential requirement for safe onehanded operation. (7) In a chamber hardening kiln the pliers are hardened in a protective gas atmosphere quenched in oil and finally annealed. The design of the hardening kiln ensures that the process gases are uniformly distributed which has a positive effect on the desired material properties. (8The cutting edges of GEDORE pliers are once again induction hardened. The additional hardness that this achieves ensures a good cutting performance and a long life between sharpening. (9) The pliers head is ground to achieve a flush geometry. (11) Nickel-plated and matt-chrome-plated to prevent dazzle. The electrolytically deposited nickel coating provides the corrosion protection. The electroplated chrome improves the look and gives the pliers a perfect finish. (14) The plastic coating on the handles is built up by multiple dipping in liquid immersion compound. The complete range form and function perfection Extremely wide selection in sizes finish and grip designs for specialists and non-specialists alike Model JC chrome-plated 2-component handle protectors Model TL black with blue dipped handle protector Available individually or in practical sets in the module or in assortments On request also available with SB pack (plastic hanging clip Euro perforation for self-service display wallboard) (12) TL pliers are painted black by a robot using water soluble paint. (10) The surface is cleaned by sand blasting. The removal of scale and grease is necessary for the follow-on electroplating process. (13) The 2-component handles are pressed on and bonded. VDE pliers are subjected to an individual test in accordance with DIN EN 60900 IEC 60900:2004. GEDORE Austria has been a certified manufacturing plant for VDE protective insulated pliers since 2003.
