Black oxidation treatment is a commonly used chemical surface treatment method for metal parts, including steel, stainless steel, copper and brass. The principle of this process is to immerse the metal in a heated solution containing oxidized salt, so that the metal surface forms a black oxide film to achieve the purpose of rust and corrosion resistance. This oxide film is usually iron tetraoxide (Fe304), which not only improves the corrosion resistance of the metal, but also gives it a black appearance. This surface treatment is widely used in areas such as precision machining projects, automotive parts, tools and decorations, and the advantages of black oxide include better corrosion protection, reduced light reflection, dimensional stability and aesthetic appeal. In short, the black oxidation treatment is a versatile technology suitable for the improvement and protection of various metal parts.

The economic adjustment to small batch sizes, we meet with our turned parts for the direct assembly in plastics and die-cast products. Any thread forms such as, thread-tapping (DIN7500), thread cutting (DIN 7513-7516) or KTG for direct screw in plastics are realized cost-effectively. Advantage is the elimination of high tooling costs, since no counter-thread in the workpiece (eg threaded inserts, nuts, etc.) is required because the direct assembly takes place directly into the workpiece. Only a given tube is required in order to screw it directly. Our turned parts replace previously cold formed parts used (so-called multi-station presses) which require high output volumes in order to achieve a reasonable price parts.

With the ring rolling mill Siempelkamp completes its range of products for the manufacture of rings. From forging the pre-forms to manufacturing the ring blanks to ring rolling, we supply everything from a single source. Siempelkamp’s ring rolling mill manufactures seamless rings made of steel and special materials such as nickel-base, titanium, or aluminium alloys using maximum radial and axial pressing forces. The radial pressing force is hydraulically generated and applied to the part via a mandrel roll. Radial rolling is carried out by reducing the roll gap between the driven external roller and the mandrel roll. The axial pressing force is also hydraulically generated and applied to the part via the upper axial roller. Axial rolling is carried out by means of the vertical forward feed of the upper axial roller. A centring device provides for the correct position of the ring during the rolling process.

Application areas for straightening presses include the sheet metal processing industry. Here, this type of press is used for the straightening of semi-nished products, such as the levelling of uneven sheet metal and slab surfaces, which are used in subsequent processes. In addition to high straightening accuracy, Siempelkamp straightening presses provide a broad straightening spectrum and high exibility in the further processing of sheet metal. For materials with a tensile strength of 1,300 N/mm2, sheet metal with a thickness of approx. 300 mm can be processed To do so, the presses are equipped with one or several straightening rams which can be operated together or individually. The pressing force needed for straightening is applied across the entire press width. Sheet metal can be straightened by cold or warm forming with sheet temperatures of up to 600°C.

The carrying frame prevents belt misalignment and guarantees protection of the belt edges. As the carrying frames only function efficiently when the drum casing is clean, they are equipped and delivered with dirt repellent 60° shore soft rubber. Our carrying frames can be used with both normal and reversing conveyor belts. Mode of operation When the conveyor belt is running straight, the axle through the roller casing forms an angle of 90° to the direction of movement of the belt. When the belt drifts, the roller casing moves, due to the dead weight of the belt, so that a forward motion occurs which brings the belt back to its normal position. The roller casing returns to its normal position as soon as the corrective procedure is completed. The mechanics of the movement are rendered possible due to a complex ball joint in the centre of the roller as well as the position of the axle in relation to the conveyor belt being less than 90°.
