we have patented tech on machine energy saving process for EPS piece molding. the traditional energy utililization of EPS molding process is inefficient,most of the energy is lose in the air. we could maximize energy utilization by apply a in-built insulated steam chamber with new polymer material, so the EPS molds won't have to be heated and cooled thoroughly again and again, and could prevent heat loses in the air, and we have PID directly control for energy input for precise control of temperature and pressure for EPS molding process, about 10-30% energy could be saved in this way.

Example regular EPS package production	ALESSIO/TEKULA	Regular EPS machine	Tested results
Pressure control	PID direct precise control	balancing valve + pressure regulator/PID indirect	NAN
EPS Molding pressure control	1bar below	1~2.5bar	Wasted steam
Insulated chamber	Applied in entire EPS fixed and mobile mold	No application around the outter side of the EPS mold	3-5℃ lower in the external part of chamber than regular EPS machine
Steam consumption	7-5 tons/per ton of EPS	10-7 tons/per ton of EPS	More than 10-30% improved than regular EPS machine

Automatic quick mold change system for EPS machine:quick connection for material supply with hydraulic mold locking device,patented hydraulic locking plier and quick connecting port,the pre-assembled mold would be connected with filling gun,water piping within just 2-5 minutes simply by just pressing one button,machine could resume to production within 5 minutes,it's a inavitable trend for EPS molding machine to go from semi-automatic,automatic machine with manual mold changing,semi automatic mold changing to full automatic mold changing.

Compare between Automatic QMC (quick mold change) system for EPS molding machine and regular machine

40 sets of EPS molding machine for a large-scale production	ALESSIO/TEKULA ALESSIO Automatic EPS QMC machine	Regular EPS machine	Tested results
Mold changing method	QMC	Semi-automatic/Manual regular	Short machine down time、less laborious job
Time for resume to production	2-5miutes	30-45minutes/1.5-2hours	Longer machine downtime
Shut down time in total	4h	25h/100h	Based on 50 molds changed on 40 sets of machine
Ratio of EPS production time lose	0.38%	2.27%/9.08%	more than 2% higher production ratio, equals extra one EPS machine

Alessio smart automatic EPS silos for molding machine

The automated centralized feeding system PMF series originated from advanced European design concepts, and can be used with PE-1.3VDA vacuum EPS pre-expander to maximize foamed EPS beads output. Among our series, the PMF-30 has a daily maximum output of 16 tons of foamed EPS raw materials and is equipped with a group of branch silos , A total of 30 silos, which can provide 12 to 24 hours of aging time, supply to 13 sets of EPS machine, it equips with valve switching system for material feeding zone supply. It is available for the precise control for multiple densities in a single zone to ensure each aging time; the available density range is 15-50 g/l; and BUS communication can be established; no manual intervention is required, providing with unmanned automatic raw material conveying system for EPS molding machine.

Intelligent software control system, based on the classic selection comparison method C++ programming framework, to ensure automatic selection of the optimal aged silo EPS raw material output at the current time period for molding machine, optional Siemens PLC control system, to ensure stable and reliable system intelligent control under harsh working conditions.

optional modular configuration mode to facilitate later expansion and upgrade, optional Internet of Things data backup interface for data access of the factory-level management system, and optional expandable display operating system to achieve local two-operation control which contribute to part of EPS automatic production line

The EPS silo feeding system adopts a centralized feeding program that is jointly controlled with the EPS pre-expander to automatically refill the corresponding density of the raw material silo; through the set pre-expansion time, the supply sequence of the raw material silo is controlled, so that the current used EPS material is always the one with the longest aged hours, and at the same time avoid manual mixing of EPS raw material silos which helps to ensure a stable and precise feeding for EPS molding machine
