Eco-Friendly Batch EPS Foam Pre-Expander with Low Steam Consumption for Fish Box Moulding

1. Innovation and Technology Presentation
The industrial-grade Eco-Friendly Batch EPS Foam Pre-Expander with Low Steam Consumption for Fish Box Moulding is a high-performance system developed specifically to address the stringent requirements of modern manufacturing facilities. Tailored for continuous or optimized high-precision batch operations, this unit sets new standards for output quality, bead uniformity, and process stability. Integrating Low Steam Consumption, the machine delivers immaculate bead structures required to manufacture structural Fish Box Moulding.
Dongshan understands that high-quality final shapes require perfect raw material preparation. This machine handles the polystyrene or polypropylene resin with extreme care, ensuring that skin thickness, pentane gas retention, and expansion ratios remain perfectly balanced throughout the entire production cycle.

2. Industry Bottlenecks and Dongshan Direct Solutions

Addressing Global Buyer Pain PointsOur engineering team has thoroughly optimized every component of this system to directly solve major operational challenges faced by factory owners:
2.1Imperfect Density Stratification: Variations between the top and bottom layers inside an expansion chamber often lead to uneven bead densities. Dongshan Solution: Multi-point steam injection paired with specialized air fluidization manifoldsensures an completely homogeneous thermal distribution.
2.2 High Defect Rates due to Residual Moisture: Wet beads lead to internal structural voids during final moulding. Dongshan Solution: The system includes a heavy-duty fluid bed dryer that uses latent heat to thoroughly dry and mature the beads immediately upon discharge.
2.3 Complicated Operational Interfaces: Complex, manual setups cause frequent human errors and scrap material
generation. Dongshan Solution: Pre-programmable formula storage lets operators instantly load precise recipes for various expansion factors.

Features

Stable density control with ≤ ±1% tolerance;
Closed constant- pressure foaming, suitable for high altitude areas;

High- quality hot air drying system for uniform beads;
International brand components ensure long service life;
Easy operation with PLC & recipe memory Advantages.

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.
