Arexim runs the most advanced materials handling technology in Bulgaria

Just 100 km between Smoljan and Plowdiw – second largest city in Bulgaria with its fairground and airport. Ideal preconditions for Arexim Engineering Ltd. to export worldwide from Smoljan. This plastics processor is renowned with customers who demand full service from product development through to fast and reliable series production. For over 20 years, Arexim has been manufacturing plastic components for the electro, automotive and home appliances industries. There are many well-known names among its customers such as Bosch, Kostal, Schneider Electric and Liebherr. Highest quality is a standard, and the latest motan-colortronic centralized raw materials handling system plays a significant role.


Sustainable production
„We only allow products to leave our factory that have been inspected and produced sustainably“, explains Krassimir Trifonov, CEO of Arexim Engineering Ltd. This can be seen by the ISO 9001:2008 and ISO 14001:2004 certifications. The family-run business has over 470 employees working in a 4000 m² production facility. In 2013, the company recorded a turnover of 17 million Euros. Some fifty highly qualified toolmakers are responsible for the production of precision injection moulds on state-of-the-art CNC machine tools. Thanks to this mould shop, Arexim can respond flexibly to customer needs.

Centralised materials management – 45 injection moulding machines
Arexim processes over 50 different material types, altogether 500 tonnes per year. And Arexim provides everything from one source – from design to the end of the project with quality assurance. Over the past few years, the company has invested 3.5 million Euros in injection moulding machines (280 to 500 tonnes clamping force) and robots. Subsequently, materials handling was modernized: “Our 45 IM machines are now fully controlled and centrally fed. This safeguards quality …”, says Kamen Dimitrov, Arexim’s  CFO, “… and motan-colortronic’s materials handling equipment meets our requirements. Energy consumption and wastage could be reduced by 10 percent.” Detlev Schmidt, Sales Director at motan-colortronic gmbh implemented the project successfully. Four METROLINK coupling stations feed the machines reliably fast.

Wear-free reliable pipe connections
Glass bends are PU coated and earthed which allows for optical monitoring of the conveying process and avoids static build-up. The METRO loaders convey quickly and cleanly ensuring the correct material is delivered to each processing machine. Consequently, production stops are almost impossible. Quiet and low-maintenance blowers generate the necessary vacuum for conveying. A self-contained drying system ensures consistent and even drying of the raw material. The system encompasses two LUXOR A dry air generators which produce 900 and 1200 m³/h of dry air along with twelve LUXORBIN A drying bins. “ETA plus® technology adjusts the air volume and drying temperature automatically depending on the material throughput; ATTN keeps the process air dew-point constant …,” explains Detlev Schmidt, “… and LUXORnet controls the entire drying and conveying system.”

Installation – no interruption to production
motan‘s modular equipment design allowed easy integration of the existing ancillary system: “Our technicians were supported by a well-trained Arexim team. The installation was completed faster than expected,” noted Detlev Schmidt. And Krassimir Trifonov concludes: “We have been working together for over 15 years. Once again motan-colortronic has proven that they are a reliable partner. Not only because of the high quality of their equipment, but also because of their creativity in problem solving and quick response to our requests.”
