MCL-C2000 is a compression-grade melamine mold cleaning compound designed for cleaning transfer molding equipment and epoxy molds. MCL-C2000 molds very easily and effectively. Most cleaning processes need no more than three shots to completely clean molds of all stains and residues.
MCL-C2000 can be supplied in loose powder or as square preforms, each with an easy break center “V-Groove,” which can be used for applications requiring smaller charge sizes. Powder or preforms are supplied in three-gallon plastic pails containing 20 lbs per pail.
MCL-C2000 is a compression grade melamine mold compound designed for the cleaning of mold stain deposited during the molding of epoxy molding compound for encapsulation of leadframe products like capacitors, resistors or semiconductor IC chips.
Mold cleaning procedure
Before molding any new material or at the beginning of a new molding cycle, it is ESSENTIAL that the mold be completely clean from the previous molding.
This point becomes more important for matte finish molds as residue can be lodged in the charmill which is undetectable to the naked eye. Any routine mold cleaning procedure should insure that the mold is perfectly clean before beginning the next cycle. If more that 8 cleaning shots are necessary, the cleaning frequency should probably be increased. For new molding compound trials, extra care should be taken since many materials are incompatible and even the slightest residue could hinder the evaluation or lead to misinterpretation of the results.
The compression mold cleaning process is the most effective for cleaning molds with large cavities and long or double runner systems. It is also the only method that will clean land areas and mold vents. A generally acceptable mold cleaning procedure for MCL-C2000 is as follows:
