How to Clean Mold Release Agent from HDPE parts?
Q. We are looking for a product that will allow us to clean mold release agent from the surface of molded HDPE parts. A. The best way to reliably remove silicone based mold release agents is to immerse the HDPE parts in very hot (170ºF) 2% Alconox detergent followed by a very hot (170ºF) rinse, ideally both in ultrasonic tanks. After the first very hot rinse, normal ambient temperature rinsing can be done. This can also be done with stiff brushes, but of course protective equipment must be worn.
The theory behind this is that …
Ultrasonic Cleaning of Glass Molds (Detergents vs. Alkali)
Q. We have heard that Alconox is recommended for glass mold cleaning. Other than release agent, can the product also remove oxidation from the mold surface? And finally, why is the concentration on the Alconox detergent only 1-3% when we typically use concentrations of 20-30% when cleaning molds with sodium or potassium hydroxide based chemicals?
A. Alconox® Powdered Precision Cleaner is what we tradtionally recommend for mold release cleaning applications, but many also find Detonox® Ultimate Precision Cleaner to be particularly effective.
When it comes to removing oxidation…
