To use both automatic purge and short purge jointly is recommended.
Short purge is a method for repeating “less measurement/weighning” and “high-speed injection”.
- In case of our 80-ton molding machine, for an example, cleaning is done by setting the measurement to 15 mm, and the speed increased from normal 100 msec to 120~150 msec.
- Rotation speed and temperature are set the same as those of molding conditions for the prior material.
- This method is effective for discharging ecomaru by subsequent material as well.
[Cleaning operation example]
- Cleaning the prior material by ecomaru using either by automatic purge or rotation purge and confirm the total discharged amount.
- For automatic purge, switch the setting to short purge in the above from the 4th shot. (when cleaning is insufficient, please add ecomaru.)
- After cleaning is completed, ecomaru should be completely discharged and replaced by post-material or PP for discharge.
- Confirm there are no abnormalities for appearances, etc. on the molded product.
* Please change the temperature AFTER ecomaru discharging replacement is completed after cleaning.
* There are chances it may not be possible to be used by hydraulic machines or older electric motors.
About purging pellet discharging
- To use discharge grade (for cleaning twice) is recommended by the other companies' purging agents, however, cleaning twice grade agent will not by sold by us and instead, other lower cost methos are suggested.
- After cleaning by ecomaru, please discard the after material or replace it by the following method;
-
"GWS" uses AS resin.
It might cause molding defects unless it is completely discharged after cleaning. Since AS resin has good wettability with metal. Especially when after material is transparent resin, utmost care and attention need to be paid. Please use PP(MFR5 ~ 10) for cleaning twice , and plan to do optimization under your environment by using it at the same amount as that of purging pellet (cleaning agent) as a guideline. When replacing it with transparent material, the amount of using PP is 1.5 times more than the amount of purging pellet (cleaning agent) used as a guideline. - "GWP" uses PP resin. After cleaning, please discharge it by low MFR PP and PE.
- Please get in touch with us individually for detailed removal methods.
About cleaning method "Injection molding machine" Automatic purging method
Pre-resin discharge
- Increasing back pressure and discharging resin.
- Cleaning hopper.
Preparation
- It is possible to be used under pre-resin processing temperature within the operating temperature range.
- Removing nozzle from mold.
ecomaru input
- Add recommended amount of purging pellet and perform purging. * Refer to usage amount guideline.
- Visually confirm the resin discharge color and make adjustments.
Injection purge
- Cleaning effect is further enhanced by increasing injection speed.
After resin input
- After cleaning, to remove glass fiber by using glass discharge agent, etc. is recommended.
- Start molding, after adding the post-material and confirming ecomaru has been discharged.
Precautions for usage
Handling precautions
- Please confirm the Safety Data Sheet (SDS) before usage.
- Please use protective gloves and goggles, etc. for your operation.
- Please keep it away from the ignition sources when using and storing it. Since this product is flammable.
- Please use ventilation sufficiently. Since gas is generated during cleaning.
- When nozzle, etc. is clogged during cleaning, please immediately turn off the power and consult with the machine manufacturer.
- Please do not touch the hot molten resin directly as it may cause burns.
- Please clean them immediately when the pellets are left on the floor. Since there are risks for slipping.
- Please do not mix with other resins.
- Please store it avoiding direct sunlight, water leaks and humidity.
- Please dispose it properly in accordance with relevant laws and regulations.
For usage
-
Please keep the operating temperature.
Please strictly keep the operating temperature range.
Please be careful of overload below the lower limit of operating temperature.
Above the maximum operating temperature, there are chances ecomaru may decompose and ignite. In addition, there is a risk of burns due to liquefaction and scattering. - Please do not use it for any other purposes than cleaning.
- Please do not get ecomaru staying in cylinder.
- Please do not use it for sealing. There are chances glass might be cooling down and gets hardened inside.
- Not suitable for cleaning by hot runner and cold runner. There are chances glass might be coolding down and gets hardened inside.
