We've added another post-curing oven. Thanks to this addition in the section, we’ve increased our post-curing capacity by over 1,000 kg per cycle, reducing production time, and providing a more efficient service to our customers. The static post-curing oven is equipped with technology that ensures complete vulcanization of our silicone, stabilizes hardness, increases compression efficiency, and boosts its breaking load. The interior space it offers allows us to work with large trays for vulcanizing significant-sized silicone profiles, gaskets, and sheets.
