Sample mounting press TVL

TVL sampling press is a unique mini test press for fast and inexpensive visual detection of undesirable contaminants in purchased or processed plastic regrinds, re-granulates, flakes, crumbs, residues from plastic production etc.

The fusing sampler consists of three modules:

1. Modul is equipped with a touch screen for setting the desired temperature (ranging from 0 to 400 °C). The internal sensors automatically maintain the temperature at the set value.
2. Modul contains a press unit (capable of exerting pressure of up to 10 bar), consisting of two heated (smoothly ground) steel plates. After achieving the required temperature (set on the display of module No. 1), the tested plastic material is poured between the hot press plates and - by rotating the press wheel – pressed into a thin disk with a thickness of 0.5 mm ± 0.1 mm. Therefore, the sample obtained in this way is sometimes referred to as "pancake".
3. Modul also consists of two smoothly ground plates, however, equipped with a cooling circuit. After pressing in module No. 2, the plastic sample is inserted between the steel cooling plates of module No. 3, where it is rapidly cooled by circulating water. Internal threads (G1/4“) allow for easy connection to the external water supply circuit.

All three modules are independent, and therefore, it is possible to purchase e. g. only modules No. 1 and 2 without the cooling module. Nevertheless, the absence of module No. 3 will significantly extend the cooling time of the plastic sample.

Advantages of the mounting press

The TVL sampling press is a very interesting alternative to expensive melt point testers. Especially small and medium-sized companies often cannot afford expensive testing equipment, however, processing or dealing with untested plastic materials can lead to damage of expensive machinery as well as considerable financial losses and may threat the company's reputation.
