Laboratory of Plastic Materials Testing

The laboratory is equipped with modern equipment for testing the physical and mechanical properties of polymer materials. It also evaluates the material structure of plastics according to international standards on standard and non-standard testing parts, semi-finished and finished products. The laboratory is equipped with a light microscope with a digital camera and with a rotary microtome Leica, an extrusion capillary microscope plastometer, an impact hammer for toughness tests according to Charpy and Izod, a Ceast notch machine with a micrometer for normalized notches preparation, a Hounsfield tensile strength testing machine with testing heads of 500 N and 10 kN for evaluating the tensile, bending, press and sliding properties of plastic materials, a Shore scleroscope with testing heads A and D, and density and analytical scales. The laboratory also houses an ultrasonic welding machine for welding plastic materials and a drying cupboard with a tool for measuring the linear dilatation of polymer materials.

 

Laboratory of Plastic Pressing

This worksite is equipped with an Engel Victory 80/25, non-column injection machine with a microprocessor control, and a water temperature control unit, part of which is equipment for temperature field monitoring inside as well as on the surface of the injection mould. It also monitors the temperature on the surface of the injected parts.

The workplace is also equipped with a machine for vacuum thermoforming of thermoplastic sheets and a blow moulding machine made by the company GDK. This equipment is for extrusion-blowing of hollow bodies and it can evaluate the influence of the technological parameters on the quality of the hollow bodies which are produced.

Here, it is also possible to produce plastic test pieces with different moulds for analysing the plastic materials properties according to international standards.

 

Metal Forming Laboratory

This laboratory is equipped with devices for testing material formability: a TiraTest 2300 material testing machine with a thermal chamber and a measuring head ranging from 10 kN, to 100 kN and 500 kN.
