Features

High exterior quality parts

Parts not allowing weld lines

High cycle parts

To improve resin fluidity in other high cycle injection

- Simplified inner structure and easy maintenance

- Triple safety device thoroughly prevents from danger of high pressure steam.

- The use of pure saturated vapor dramatically improves temperature distribution and thermal efficiency and lowers pressure.

- The well-designed channel configuration (diameter, position, number) and control reduce cycle time.

- There is no need to make major modifications to the molding equipment.

(No modifications for sheathing cartridge heater and core parts)

- Certain range of injection condition allows chiller to be linked and controlled (option).

- Integration of steam boiler and control unit offers excellent portability.

- Order-made specifications are available.

(Ex : Boiler 30 bar, Tank capacity 500 ℓ, Separate temperature control of stationary and movable mold, etc.)

Unparalleled qualityInnovative level of quality : High glossy, No weld lines

Groundbreaking productivityInnovatively increasing productivity : Reducing cycle time, No coating, No Scratch

Upscale precisionBest-in-class accuracy : precise injection molding of LCD light guide panel

Heating & Cooling perfomance

* To increase mold temperature improves resin fluidity. Thus it reduces hold time.* The above cycle time varies with injection molding machines.A) In consecutive production process, RICH rapidly heats up mold so reduces vacuum time. It cools down mold at proper time. Thus it reduces cooling time.

- Cycle time : 95 sec (without RICH) → Cycle time : 72 sec (with RICH)- RICH heating : 14sec / RICH cooling : 25sec

- Cycle time : 90 sec (without RICH) → Cycle time : 60 sec (with RICH)- RICH heating : 12sec / RICH cooling : 23sec

- Cycle time : 60 sec (without RICH) → Cycle time : 46 sec (with RICH)- RICH heating : 18sec / RICH cooling : 28sec

- Cycle time : 20 sec (without RICH) → Cycle time : 9 sec (with RICH)- RICH heating : 1.5sec / RICH cooling : 5.3sec

Reducing cycle time and increasing productivity

* The above production refers to experimental data from "O"company in Korea.

* The use of saturated vapor dramatically improves temperature distribution and thermal efficiency and lowers pressure.

* More thermal efficiency than gas steam boiler and easy operation.

* Cartridge heater system requires major mold modifications. Thus maintenance is difficult. More time to heat up due to limit of heater capacity.
