Application examples

Some selected examples for the use of laboratory presses as hot presses

Example of the use of a press for the production of sample plates:

Using a press frame, a test sample plate can be made from plastic granulate or elastomer from which test rods can be punched for subsequent tensile tests:


Example of the use of a vacuum press:

In the field of the manufacture of special compacted carbon parts of special carbon in connection with the investigation on material properties as catalyst (university):


Example of the use of a 3D tool in connection with the manufacture of implants of highest quality special plastics:

Special anti-slick coated hot pressing tool:

abt. 3 cm diameter of an implant; lower half shell
Upper and lower half shell jointed as complete hollow body
Tool carrier

Manufactured for use on a vacuum press by VOGT Labormaschinen. If interested, you will find more details in the pdf file: FHG-Potsdam IBMT Paper zu Sensorkapsel


Example of the use of a laboratory press in connection with the manufacture of plate material of thermoplastic recycling chips from ocean waste (project: Ocean Plastics):

33-beispiel-nicht-ihre-groesse Application example: manufacture of a melted raw plate from recycling chips for subsequent design bodies (possible application example: spectacle frames from the so called plate goods)


Example of the use of a laboratory press in connection with the material receipt testing of soft PVC:

(user: a renowned car manufacturer): Application example: manufacture of a test sample plate – here as illustrated, just got out of the tool and still uncut – made of powdery PVC material which is used in a car dashboard. Laboratory machine and the corresponding immersion tool equipped with sprue cavities made by ours.


Example of the use of a laboratory press in connection with the manufacture accompanying material testing – 24/7 days availability required:

invista_platte  invista_granulat Application example: temperature pressing for surface enlargement for the purpose of density measurement 20 granulate grains must be defined and pressed flat with repeat accuracy, with specific surface compression force above 120.000 N/cm²


Pore compacting of plastic tissue:

Application example: defined and repeat accuracy pressing of special tissue of plastics in order to achieve a certain determined pore size. Tissue treated this way may be suitable due to the determined pore size as base material for certain gas sensors  whose pore opening is adjusted to the gas molecules to be detected . As function of the aligned gas type, a pore size defined for the molecule type can be defined. A special recipe administration in our laboratory press, user surface allows for quick access to the desired  different treatment types to be applied to the desired tissue. E.g. 20 different pressing programs for 20 different molecule types. Application example: same type of application, however with a completely scope of use. Pore compaction with the aim to precisely influence with repeat accuracy the acoustical resistance value in a microphone by defined compression forces and temperatures. 


Coating of chipboards:

Application example: raw chipboards or MDF plates will be coated with a décor. This can be used e.g. in floor coatings (e.g. laminate) or in furniture boards with different appearance. For this purpose, décor layers will be bonded with the raw chip material and coated in case of need in addition with resistant protection layers against moisture or discolouring. In part, in addition to the pure décor layer an embossing process will take place in order to impart a more natural appearance to the décor. Bonding and protection layers will be pressed by the laboratory presses under defined and repeat accuracy conditions as laboratory samples for quality testing or sampling or for new developments.


Example of the use of a laboratory press in connection with the testing of coatings with so called “baked paint” (electrical insulating coatings):

Special anti-adhesion coated hot pressing tool  :

CAD design draft of baked paint tool
Fed carrier tool without pressure cover , completely anti-adhesion coated
Fed carrier tool with float guided pressure cover

Application example: at the manufacture of so called “baked paint” (use as so called. electrical insulating coating), the coating thickness and the bonding quality are of particular importance. For this purpose, test sheet-metal strips will be inserted as stack into the tool and subjected to a treatment of defined pressure patterns and temperature profiles (up to 4 hours of heating time are feasible). Baked paint will melt and leak off, and the rate of leakage can be measured. After emptying the supernatant leaked off, conclusions can be drawn on the quality of the coating by weight comparison of the before and after condition.. Besides the leaking off paint supernatant, also the bonding will be measured by mechanical pulling apart and measurement of the forces this requires.
