Name

Polymers PVT Tester

Model

PVT-6000

     Description                                                     


   PVT tester is designed for analyzing the polymer in the pressure, volume, temperature changes, using a fixed cavity membrane heating structure to fix the volume of polymer. The optimum process parameters of injection mould-type production process is calculated by the variation of volume and density under different pressure and temperature to reduce the defect of warp, shrinkage, bubble and suture in the process of processing, so as to reduce the scrap rate increase productivity and obtain high quality product efficiency. 

Heating or cooling a certain amount of polymers according to the set temperature or use rate temperature control, and improve the accuracy of temperature control by the simulation volume of air-flow cooling system, using the servo motor control pressure plunger keep constant pressure in accordance with the set pressure, using the high precision optical ruler measuring the expansion or contraction volume when the polymer temperature changes, and conclude the density, specific volume and other data for analyzing.
