High precise full auto EPS Styrofoam Batch Expander Machine
EPS High precise full auto batch expander machin is a crucial piece of equipment in the production of Expanded Polystyrene (EPS) products. These machines take raw EPS beads, which are small and dense, and pre-expands them through a controlled process of heating and pressurization followed by rapid depressurization.
This process increases the volume of the beads by several times, making them ideal for molding into lightweight and strong EPS products like packaging materials, building insulation, and protective cushioning.
Characteristics
1.High Precise full auto EPS Styrofoam Batch Expander Machine use for expanding and producing EPS foam beads and the computer automatic control the whole p rocess, automatic feeding and weighing material, realize automatic production. This pre-expander has different types for customers with small, middle and big capacity and different required density. It can finish first expansion and second expansion.
2.This pre-expander has a big capacity, apply the imported spare parts such as the Germany and Japan famous brand, the products with very small tolerance.
3. The machine has the drying system inside barrel, and with the drying bed for second drying.
4. The machine design with advanced design and making, It use several steam pipes into the barrel which keep the steam equality for the same size EPS beads and high quality products. The machine bottom has several clean door which can clean the barrel inside anytime, it is easy to repair and operation. The feeding and weighing system can be put on the top of the machine, which can save the space of the workshop.
5. The machine use the high quality material to make, the barrel and main spindle and mix rods, material hopper and door all use the 304 Stainless steel, the main barrel has three layers, very few problems, with a long working time.
6. The machine with the function of auto adjusting the density of the material.

Advantages
Frequency spindle: the spindle rotation speed can be adjusted according to the raw material process,for ensuring that the material level 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 devi ce will automatically weigh to achieve accurate feeding.
Material level control: adopt the vibration sensor from Korea to control expanding material level precisely, ensuring the uni form 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
