EPP Expandable Polypropylene Pre-expander foaming Machine
1. Accurate weighing and quantitative feeding system replaces time control feeding, and the level sensor ends heating to eliminate external instability factors and ensure accurate pre-acquisition weight.
2. Relief valve and proportional valve PID control barrel pressure, with compressed air bypass, achieving the best foaming pressure and minimum steam consumption.
3. The bottom is wedge-shaped and permeable, with large intake area and uniform steam distribution.
4. Hot air discharging by fan, realizing fast discharging and less machine condensation water.
5. Electrical appliances, pneumatic components, valves, etc. are all well-known brands at home and abroad to ensure the stability and reliability of the machine operation, and prolong the service life.
6. Automatic density measuring devices are optional.
