What Type of Machines/Equipment Does ASACLEAN Work With?

Question
Does ASACLEAN only work for cleaning injection molding machines?

Answer
No. While mechanical grades of ASACLEAN may excel in cleaning injection molding machines (screws, barrels and hot runner tooling), they are also quite effective in cleaning extruders (profile, resin-compounding, cast sheet, cast film, blown film and blow-molding). We offer chemical grades of ASACLEAN that are ideal for applications involving low flow or low pressure environments. ASACLEAN technical sales reps. will help you select the best grade selection for your application.

Question
Can ASACLEAN clean my extrusion die?

Answer
While ASACLEAN is not specifically a die cleaner, in most cases ASACLEAN effectively cleans a variety of extrusion dies.

Question
Can I use ASACLEAN to purge out hot runner tooling?

Answer
Absolutely. ASACLEAN works effectively to purge out a variety of hot runner systems, using either an “open-mold” or “closed-mold” purging method. In fact, ASACLEAN is highly recommended by some of the larger names in the hot runner industry.

Question
Is this Compound good for both PS and PET Extruders?

Answer
Yes. Our general purpose U grade is a styrenic based multi-resin cleaner.

Question
Does it work for hot runner vs extrusion blowmolder head?

Answer
We have grades that are effective in hot runners, as well as grades that are better suited to extrusion grades.

Question
Is one grade good for both Polystyrene and PET?

Answer
Our U grade is an all purpose, strong cleaning, low residue purging compound. However, we also have E grade, which is our lowest residue cleaner, and is often used in applications where transparency is critical. I recommend getting a sample of both grades and trying them in your applications.

Question
What do you recommend for a high capacity HDPE line(800 lbs/hr) with high carbon black content (2-3%) when shifting from black to white? It’s a multilayer film blowing process so we can’t use glass filled compounds due to the possible die damage.

Answer
We agree that you must avoid glass filled grades on highly polished dies. Knowing that this is for blown film, I recommend our UF2 grade, which is an olefin based product aimed at your specific application. You may also want to try our general purpose U grade, as it is a powerful cleaner for a wide variety of applications.

Question
What is the best way to clean out a hot runner system in a stack mold with 64 cavities?

Answer
We would recommend trying an olefin based mechanical purge. It depends on if you have a lot of dead spots in your hot runner. We are partial to a high flow mechanical purge like our UP Grade.

Question
We use 40 to 60 melt material, we tried using your compound and found that our material was flowing over the top of the purge compound. What do you suggest to prevent this from happening?

Answer
We recommend using a high flow, olefin based cleaner like our UP Grade.

Question
Do you have a purging compound that can be used to run parts and recycle through regrind?

Answer
We do not recommend that commercial purging compounds enter the re-usable regrind stream. However, most of our grades are moldable, so you can purge while running to reduce downtime. Please just make sure to cull out the parts made with purging compound.
