Die-plates

Die plates are used in the underwater pelletizing of polymer for making uniform pellets.

Originally core jacket and heat exchanger type of die plates were used in underwater pelletizing, but now a days mainly heat channel die plates are used.

To withstand the excessive wear of the rotating knives for cutting the pellets the die plate has a hard metal face. Although the hard metal can be small tiles or nibs with the die hole, modern die plates have hard metal segments.

The hard metal of the segments is made of TiC or WC and bonded by a proprietary process. The quality and stand out of the hardmetal is important for depending the life of the die plate.

Please contact Mercatel in case you need a quotation for a new die plate, replating (re-tiling) or re-grinding of an existing die plate.
