Engraved Mold

MK Technology's R&D Institute developed new technique to build sipes. In accordance with the result of extensive study, MK differentiate sipe build methods; conventional sipe insert and direct engraved sipe. And it has been a chronical question,"How many sipes can be installed into the engraved tread with cost advantage? MK successfully supplied engraved segment tread with over 1,000 sipes already supported by R&D engineer's special project.

MK Technology selected material for engraved mold primarily with WELDURAL, German made special aluminum alloy and as an alternatives M-1, American made aluminum alloy as well as conventional ASTM 514 for PCR and TBR. In accordance with customers' requirements, MK also produces steel engraved mold especially for those customers who want improved quality while conservatively stay with conventional steel mold characteristics especially for the truck/bus radial tires.

Engraved Mold

MK Technology's R&D Center invested many years of time to develop industry new engraved segmental mold process and entered into the commercial production since 2001. This new process demonstrated unprecedented improvement of the mold quality compared with the conventional casting mold in many areas; dimensional accuracy, increased mold life as well as reduced production lead time.
