Drying
Moisture content in plastics adversely affects the quality of molding. Excessive moisture in resins leads to products with unacceptable sturdiness, silver streaks and holes. Drying primarily serves to remove moisture from resins to prevent drops in the quality of molded plastics. At times, temperature increase is used to enhance the plasticity during molding.
Dehumidifying Technology
Circulation of air in the rotor.
The honeycomb rotor is made up of three zones: dehumidifying, regeneration and cooling. The dehumidifying zone absorbs air moisture charged into the hopper dryer. The regeneration zone heats the moisture absorbed by the dehumidifying zone to evaporate it, regenerating the honeycomb rotor. The cooling zone cools the honeycomb rotor, which was heated during regeneration, to an optimal temperature for dehumidification. These three zones enable the honeycomb rotor to provide a stable low dew point of -40℃. Initial functionality is maintained even without replacement of absorbent materials.
Dew point measurement data
MATSUI's honeycomb DMZ system supports a dehumidified air environment with a stable low dew point (-40℃ or below)
Vacuum Thermal Conduction Technology
Vacuum thermal conduction
Shortens drying time by creating a vacuumed condition. Conduction fins increase surface area and hence ensures that all materials in the hopper can be heated at the same time. Because it does not use hot air, exhaust hot air is not emitted.
The gas removal effect
Greatly reduces mold maintenance. Plastic pellets heated by air may discharge a gas that forms a film on the mold surface. MATSUI's Thercuum heats by thermal conduction, eliminating harmful mold films.
