Company History and Background

STOK Engineering Ltd. was established in 2002 in Plovdiv, Bulgaria, by Stoyan Kiryakov with the goal of providing engineering solutions to local companies in the food and beverage industries. The company began in-house manufacturing in 2004 and has since maintained the highest level of quality standards in both engineering and manufacturing.

The decades of expertise of our founder and chief engineer, Mr. Kiryakov, as well as the experience of our team of engineers, have enabled STOK Engineering to create a differentiated portfolio of solutions and products. Our innovative designs provide clients with cost-efficient products and highly-customized solutions. We have also helped clients benefit from our specific industry-domain knowledge.

We source parts and machine components only from renowned suppliers such as: Schneider Electric, KEYENCE, Bosch Rexroth, and HENGSTLER.

To this day, STOK Engineering remains a family-owned and operated business. We are dedicated to delivering lasting value to our customers, ensuring safe working conditions, and sustaining the livelihoods of our employees — all while leaving a neutral footprint on our environment.
