Complete removal of rubber residue and gas stains that stick to a mold is required in order to maintain the quality of molded rubber products. However, cleaning molds with a solvent, blasting material, or brush has problems: it cannot remove stains sufficiently and it requires additional processes and time other than cleaning, such as cooling and disassembling molds.

The Mold Cleaning Sheets that we developed can clean molds by simply sandwiching them between molds and heating them. They not only shorten the cleaning time but also boost productivity and ensure quality.

The conventional mold cleaning method includes numerous processes other than cleaning, such as cooling and removing a mold before cleaning, and attaching and warming a mold after cleaning, which are both labour- and time-consuming.

• Clean molds without removing them from a molding machine

Our Mold Cleaning Sheets are mainly cleaning materials composed of thermosetting synthetic rubber. The cleaning agent contained in the sheets permeates and dissolves stains, and the adhesive force of the synthetic rubber removes the stain components. Our cleaning sheets do not require the disassembly of a mold for cleaning. Moreover, rubber residue and gas stains sticking to the mold can be removed in the same process as in the molding process: they are sandwiched between the molds equipped to the molding machine and heated.

i. Cleaning Mechanism of Mold Cleaning Sheets

• Realize rapid mold cleaning

You can clean even a heavy mold without detaching and attaching molds, which improves work safety and significantly reduce the number of cleaning processes.

i. Example of how our cleaning sheets reduce the required time in a mold cleaning process

• Improve safety & quality in mold cleaning processes

The blast cleaning method, where stains sticking to the surface of molds are removed by colliding blast materials (granular materials) to them, has problems: it may deteriorate the quality of the molded products, such as making scratches on the mold surface due to the blast materials and scattering blast material. Our Mold Cleaning Sheets remove stains by adhering them to the surface of the sheets, which prevents mold deterioration caused by cleaning.
