Continuous EPS Raw Material Pre-Foaming Machine with Density Control for EPS Hourdi & Asmolen
1. Commercial and Industrial System Identification
The highly optimized Continuous EPS Raw Material Pre-Foaming Machine with Density Control for EPS Hourdi & Asmolen represents a significant milestone in high-speed expandable polystyrene engineering. Built to operate continuously under intense industrial schedules, this system combines excellent mechanical durability with sophisticated digital control networks. Equipped with Density Control, it gives factories the exact operational control necessary to mass-produce premium-grade EPS Hourdi & Asmolen with exceptionally low per-unit production costs.
Dongshan focus on maximizing your return on investment (ROI). By engineering the machine to minimize raw resin waste and optimize energy use, this machine turns standard materials into high-value components with unmatched repeatability and speed.
2. Critical Market Challenges vs. Dongshan Solutions
To succeed in high-volume markets, manufacturers must eliminate common processing inefficiencies. This system provides direct solutions to the industry's most common pain points:
Material Loss During Startup & Shutdown: Standard machines waste significant amounts of raw material during calibration cycles.
Dongshan Solution: Automated pre-heating routines bring the expansion chamber to exact operating temperatures before resin enters, eliminating initial scrap.
Excessive Electric Power Consumption: Running heavy fluid beds and heavy material transfer blowers can cause high electrical utility spikes. Dongshan Solution: Optional variable frequency drives (VFD) adjust motor speeds based on realtime load requirements, cutting power use by up to 30%.
Inconsistent Material Feeding: Clumpy or irregular raw material delivery can disrupt expansion cycles and cause uneven densities.
Dongshan Solution: High-precision vibrating feeding screens ensure smooth, steady raw material flow into the expansion chamber.
3. Production Throughput, Efficiencies, and Controls
By leveraging Density Control, the machine achieves high operational speeds while keeping energy consumption down. The internal expansion chamber features polished stainless steel surfaces to prevent beads from sticking, maximizing material yield. Advanced diagnostics track your steam, air, and electrical usage, providing managers with clear data to optimize floor efficiency.

Frequency spindle
The spindle rotation speed can be adjusted according to the raw material process, for ensuring that the material leve can control the expanding weight precisely.
Steam system
Adopt relief valve from YOSHITAKE,Japan, with high- precision drainage valve and filter to ensure steam pressure more stable.
Pressure control
International pressure sensor, German BATTON angle- seat valve and multi- valve exhaust system are used to ensure constant temperature and pressure expanding in the bucket, make sure the expanding process more stable and accurate.
Temperature control
The international temperature sensor and German BATTON steam and air dual proportional valve are used to control the temperature, so maintain the precise expanding temperature, for high – density expanding.
Weighing and feeding
Electronic weighing for feeding, and the feeding weight is setup on the touch screen. The weighing device will automatically weigh to achieve accurate feeding.
Material level control
Adopt the vibration sensor from Korea to control expanding material level precisely, ensuring the uniform density of raw material particles.
Material level of fluidizer bed: the height of material level can be adjusted to ensure the aging effect of expanded particles.
Flap feeding device of fluidizer bed ensure the high efficiency of expanding particle feeding .
Crushing device at bottom of fluidizer bed: to ensure convenient clean of fluidizer bed.
Mark
1. automatic weighing system of density is optional.
2. X-1400, X- 1670 second expandable function is optional.
