EPO is an expanded polyolefin material often used in the manufacture of larger airplane models. EPO material offers high strength, lightweight characteristics, and excellent aerodynamic properties, making it the material of choice for crafting high-performance airplane models. Unlike EPS and EPP, EPO typically requires injection molding processes to create complex wing and fuselage shapes. This process allows for greater precision and surface quality, suitable for aircraft models that demand superior flight performance.

Feeding system
1. Adopting the structure of horizontal double rotating disc discharging barrel, there are 44-1" discharge ports, which can fuly meet the requirements of customers with multiple products and multiple guns; Also vertical double material tank optional.
2. In order to avoid uneven mixing of horizontal material, double-rotating discharge tray has the advantages of relatively smal cross-sectional area of vertical barel and good sealing.
3. Control of material position resistance switch Material alarm shutdown function, with pressure feeding, vacuum feeding, intermitent feeding function.
Steam system
1. Adopting Japan Yoshitake steam pressure reducing valve, steam flow and pressure is stable.
2. Use Japan SMC's electric proportional valve and the US MAC's high-frequency solenoid valve to control the mold steam inlet pressure.
Vacuum system
1. Simultaneously configure vacuum tank and condenser to increase the vacuum volume.
2. The top of the vacuum bucket is equipped with a detachable sprinkler device, which increases the vacuum condensation ratio by spraying the cooling water, thereby improving the vacuum suction efficiency.
3. Make the equipment truly achieve the effect of cooling water vaporization and heat absorption, and the product has low water content.
