Advantages of Columbus vacuum presses

Machine construction
  • The upmarket Columbus machines are the result of decades long, market driven research and development. They were created by and for practitioners and perfected together with operators and manufacturers of materials.
  • The massive welded steel construction is 100 % torsionally rigid and resistant against bending, even when processing big work pieces. The results are longevity and production safety in any situation.
  • The ergonomic and smooth-running operation ensures an absolutely body-friendly working method even during fast production processes, what minimizes downtime and ensures fatigue-free working.
  • Columbus membranes are extremely heat resistant and very resilient against abrasion, this minimizes expenses on wearing parts.
  • They have extraordinary elasticity and rebound capabilities and guarantee best pressing results for a long time.
  • Depending on the required heat resistance and mechanical load, Columbus membranes are available in different material types and quality categories (natural rubber, silicone economy, silicone high-performance). Thus, there is always the ideal equipment at the best price for every application.
Membrane fast-change system
  • With the unique Columbus membrane fast-change system, a membrane change can be carried out in less than 10 minutes, what optimizes production processes and significantly shortens production times.
  • The sturdy steel frame guarantees a vacuum-tight membrane attachment and thus ensures the best press results and production safety.
Phenolic resin working surface
  • The Columbus working surfaces consist of a very heat-resistant and robust phenolic resin laminated plywood. These guarantee longevity even with the toughest use.
  • The integrated air suction channels in the working surface, with up to 70 suction points, facilitate full ventilation and evacuation. With this system, maloperation by incorrect placed work pieces is impossible, what minimizes reject rates. Furthermore, the air Air suction speed increases through that and an evenly spread pressure is guaranteed.
Vacuum pump
  • The high-performance vacuum pumps from Columbus are 100 % oil-free. While conventional oil-lubricated vacuum pumps spread their lubricating oil throughout the entire room as a harmful and surface-contaminating oil mist, Columbus dry-running rotary vane pumps ensure clean and safe production facilities for people, materials and environment.
  • Depending on the requirements and the size of the machine, Columbus offers a variety of high-performance vacuum pumps with different Air suction speed. Thus, there is always the ideal equipment at the best price for every demand.
  • High-performance vacuum pumps from Columbus are maintenance-free. This means no expense for servicing - neither time nor cost.
Control unit
  • The pump and the heating drawer are controlled via a separate, functionally arranged control cabinet.
  • Vacuum generation and vacuum reduction are controlled via a vacuum control lever, which is placed centrally on the machine.
  • The vacuum pressure is monitored via a precise analogue vacuum pressure gauge in bar relative.
  • The temperature and heating time control of the heating drawer are digital.
  • Thanks to the central and clear provision of all control and monitoring elements, the production process can be extremely speeded up and optimally monitored.
Vacuum pressure control
  • With a vacuum pressure control, the vacuum pressure of the vacuum press can be adjusted variably. Since the processing of certain materials (e.g. very soft materials) requires an adapted vacuum pressure, new, profitable application possibilities are opened up with a vacuum pressure control.
  • The vacuum pressure can be controlled with either a mechanical regulator, or a digital controller.
  • The digital vacuum pressure control is available in combination with a 200 l vacuum tank, which enables an extremely fast vacuum generation. Due to the faster vacuum generation, materials and adhesives can be processed with very short process times.
Vertical opening mechanism
  • The vertical, pneumatic opening mechanism guarantees precise pressing of different shapes and geometries, since the vertical travel does not cause any shifting of the layers and the base stencil. This level of precision reduces reject rates to zero.
  • The possibility of a 4-sided operation of the vacuum press ensures an uncomplicated and fast workflow and increases productivity.
  • The reliable, oil-free pneumatic cylinders protect work pieces and the production facility against oil contamination.
  • The built-in two-hand safety operation guarantees maximum safety.
Heating drawer
  • With the heating drawer, all thermoplastics, solid surface materials and composite materials can be heated temperature-accurately, to form them afterwards in the vacuum press. This application offers magnificent opportunities for expanding the product range and opening up new markets with inexhaustible revenue potential.
  • The built-in CHS heating system ensures very efficient heating performance and guarantees an extremely fast heating process that enormously speeds up the entire production process.
  • The high-performance circulating hot air fans distribute the hot air evenly throughout the entire heating drawer and thus ensure an exact temperature distribution on the workpiece. This guarantees best results during the pressing process and prevents rejects caused by uneven heating.
  • The sturdy and extremely heat-resistant construction guarantees longevity and production safety even under high influence of heat.
  • The electronic temperature control allows variable temperature adjustment up to + 230 ° C and allows precise monitoring during the entire heating process.
  • The non-corrosive, pull-out working surface with grating has a grid of 30 x 30 mm and is very easy to operate. It is so massively constructed that even heavier materials, which would twist conventional heating drawers, can be inserted without any difficulties.
Perforated stainless steel sheet
  • The working surface of the heating drawer offers a 30 x 30 mm grid in the standard version. The optional insertable perforated stainless steel sheet provides a flat, smooth surface on which sensitive materials (such as transparent plastic) can be heated.
  • Due to the perforation, the heat distribution is not affected by the perforated stainless steel sheet and the heating results are just as perfect as with the working surface of the standard version.
