EPS pre-expander

Batch Pre-expander foam machine Plastic machinery PLC programmable controller and touch screen to realize man-mach

Batch Pre-expander ( EPS machinery , Plastic machinery,foam machinery)

Features: 1) Uses PLC programmable controller and touch screen to realize man-machine dialog2) Uses charging device of automatic negative pressure, electric weighing, and level switch to realize automatic feeding and gauge3) Uses auto-controller of temperature and pressure in the chamber and photoelectriclevel material to realize the uniform and light density of the beads4) EPS beads is formed in the auto-cycle by shock sieve, crushing and transportation fan5) Uses imported steam reducing valve and proportional valve (optional) to ensure the stable pressure of the reducing valve outlet, and the temperature tolerances within ±1°C in the chamber. If the block density is above 30kg/m³, the proportional valve should be installed6) Hot air drying system (patented) in the fluidized beds with temperature up to 75°C ensures the EPS raw material drying and fast molding, speeds up the aging process and shortens the production cycle7) Separation of auto-charging device and electric weighing with the machine avoids the inaccuracy and unreliability of electric weighing caused by operation8) Four security devices on the machine ensure that it operates normally and safely9) For production technical memory and quantity statistic, operator can find the foamparameter of manufacturer's used EPS raw material and simultaneously set the different foam parameter by themselves10) For statistics and account of EPS production per day, week, month or year, the electric weighing can be installed with digital printer optionally11) Remote communication system can be optionally used to monitor the machine and remedy its faults12) Software system can be upgraded to improve its processing properties13) Hot air drying system (patented) in the foam chamber with temperature up to 75°, makes EPS beads drier, resulting in the density of foam up to 11kg/m³, making forming quickly, especially cut down the fluidized bed to facilitate the beads' transportation, speed up the aging and shorten the productioncycle14 Uses new EPS foam processing technology to improve its production efficiency,which ensures that EPS beads foam more accurately, lightly, fast and have low fault rate during its secure operation
