Each of the cleaning techniques for molds has their own advantages and disadvantages, but, when used correctly they all are capable of cleaning your molds. When used in combination, they may be even more efficient than one method alone. The cleaning process is achieved by the use of chemical and/or mechanical scrubbing.

NOTE: It is important to make sure that the mold is thoroughly cleaned before start up of molding to ensure good molding results. Mold cleaning and conditioning compounds must be compatible with your molding compound. For best results, check with your representative for compatible products.

CARNAUBA WAX BASED MOLD CLEANING AND CONDITIONING PRODUCTS WILL YIELD BEST RESULTS WITH MOST EPOXY COMPOUNDS. IF USING SILICONE-CONTAINING PRODUCTS, IT IS IMPORTANT THAT THE PRODUCT STATES SPECIFICALLY THAT THE PRODUCT IS COMPATIBLE.

Mold build-up and/or mold stain is a function production time and the number of shots. Use the table to select the best cleaning method for your application.

Procedure for Cleaning with Rubber Sheets

  1. Use your standard molding conditions
  2. Place rubber sheets over the cavities and runners
  3. Close the mold and cure for 5 minutes
  4. When press opens, remove the cured sheets
  5. Check sheets and mold cavities for stain
  6. Repeat the above steps until the mold is completely clean & stains are no longer transferred to the rubber sheet
  7. Remove the residual rubber film with a shot of compression or transfer melamine

Procedure for Cleaning with Transfer Grade Melamine

  1. Use your standard molding conditions
  2. Use the same volume of melamine as molding compound (the specific gravity may be different)
  3. Mold at 170-180 °C for 5 minutes
  4. When the press opens, remove the cured parts and runners
  5. Inspect the parts and cavities for staining
  6. Repeat the above steps until the mold is completely clean and stains are no longer transferred to the cured molding compound

Procedure for Cleaning with Compression Grade Melamine

  1. Reduce the clamp pressure by at least 50% to avoid damaging the delicate positioning pins
  2. Place the melamine preforms over the cavities and runners
  3. Close mold and cure for 5 minutes
  4. When the press opens, remove the cured melamine
  5. Check melamine and mold cavities for stain
  6. Repeat the above steps until the mold is completely clean

Continue cleaning until the cleaning compound has removed all of the mold buildup and mold stain.

How to Condition the Mold

The melamine cleans the mold down to the bare metal. It is necessary to have a layer of wax on the surface so that the mold compound will release from the mold.

Once the mold is clean, follow these steps:

  1. Set the press to standard processing parameters
  2. Prepare the mold by first lightly waxing with spray wax
  3. Then mold 3 to 5 shots of conditioning compound or 3 to 5 dummy shots of standard mold compound, using a curing cycle 2 to 3 times longer than normal
  4. The first three shots of standard molding compound should be cured 2 to 3 times longer than normal in order to insure that press equilibrium temperature and optimum release characteristics are achieved
  5. Then resume molding under normal process conditions

Compare our Cleaners & Conditioners

Mold Conditioners and Cleaners vary greatly in their composition and their application. There are melamines and heavily waxed mold compounds and other materials that can be used. These are available in sheets, pellets and other forms.
