Press forming - Import export

The O-forming press applies a press force of 4,000 metric tons per meter of pipe. This is necessary to form today’s material grades above X100 to the desired round shape at the optimum level of reduction. The control concept with (patented) multi-cylinder parallelism control ensures that the moving beam maintains a position parallel to the press table with a tolerance of +/-1 mm/m over the entire length. Combined with our tools, this results in a precise pipe gap which leads to signicant time and material savings for the subsequent welding process. The intelligent sensor and control concept of all main cylinders ensures that dierent sheet lengths (e.g., residual lengths) can be processed. The press is powered by either conventional drive concepts or via frequencycontrolled drive concepts. Our ECO Drive uses the high moving load of the moving beam to generate energy during the controlled quick lowering of the beam. This energy is fed back to the power network.

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 combination of multiple technologies/procedures in one step is called OneShot technology. Semi-finished products (e.g. renewable raw materials such as natural fibers) and decorative materials (e.g. textiles) have to be handled in one production step to finish a component, such as a door panel. FRIMO has developed a modular system that allows for simple and customized configuration of a OneShot plant with all necessary tools. The following units can be integrated into such a plant: feeding station, heating station, calibrating station, material assembly station, press with OneShot tool, part-removal station.

Composites are engineered materials made from two or more materials with significantly different physical or chemical properties. Their mechanical and physical properties depend on the type and proportion of the base materials and the parameters of the manufacturing process. Due to composites, very light and durable plastic parts can be produced. Composites may be prepared as layers , fibers, particles or penetrating composites , but the actual composite material usually only arises during the shaping process in the tool . FRIMO has extensive technical expertise and many years of experience in developing and manufacturing plants and tools to process composite materials such as CFK, GFK, NFPP, HFPP, LFT, GMT and BMC and supplies for the production processes such as RRIM, SRIM / GMPU, Long Fiber Technologies, NFI, or RTM tailor-made manufacturing equipment.

"Combi" tools allow different technologies to be combined in a single step (in one tool) for more efficient plastic component production.

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.

Siempelkamp is number one in tailor-made plants for the leading manufacturers of pipeline pipes. These large-diameter pipes with longitudinal weld seams are manufactured using crimping, U-forming, and O-forming presses. Compared to other processes on the market, these three presses achieve high production outputs of up to 30 pipes per minute regardless of the pipe diameter. For these large presses featuring our proven metal frame construction, the heavy component parts and tools are manufactured in our in-house foundry. The three hydraulic presses present the essential forming units of a modern production line for longitudinally welded pipes with lengths of up to 18 m in three forming steps. For each of the three forming steps, Siempelkamp oers the optimal press and the associated equipment for the forming line (e.g., pipe transport, lubrication, measuring).

The ContiRoll® press is the core element of the forming and press line and at the same time the focus of Siempelkamp’s innovations. More than 300 presses have been sold to all parts of the world since its launch 30 years ago. The concept has been continuously developed by Siempelkamp ever since, especially product quality, user friendliness and resource eciency. The exible infeed section adjusts to the formed mat in dependence on the recipe thus oering an optimal combination of a quick pressure build-up and a reliable evacuation of air from the mat. The booster heater integrated in the infeed end transfers a maximum of thermal energy into the mat. Very fast pressure and temperature build-up ensure an optimal density prole and excellent physical properties of the engineered board. Today, the 8th ContiRoll® generation is in use. It oers almost isobaric pressure distribution. Patented pressure distribution plates ensure consistent pressure in working direction acting on the product.
