Engineering That Has Powered Heavy Industry Since 1986
Since 1986, AYDINLAR DISLI & MAKINA and AYMAK CELIK have been developing mechanical power transmission systems, custom machinery, and plant equipment for heavy-industry applications, drawing on their extensive experience in engineering, design, and manufacturing. The companies conduct their manufacturing operations in the İzmir Kemalpaşa Organized Industrial Zone on 8,534 m² of company-owned land.
The facility has a total building footprint of 5,020 m², of which 4,420 m² is allocated to production. The multi-storey office and administrative building has a total enclosed area of 1,800 m². When all floor areas are included, the facility’s total enclosed usable area reaches 6,220 m².
The modern manufacturing facility was established in 2004 as a comprehensive greenfield investment. In response to increasing production capacity, the manufacture of large-scale equipment, and new project requirements, an approximately 2,500 m² facility expansion was initiated and completed in August 2023. These investments expanded the production areas and strengthened the infrastructure required for machining and assembling large and heavy components.
The production facility is equipped with six overhead travelling cranes of various lifting capacities. When three cranes are operated in tandem, a maximum lifting capacity of 55,000 kg can be achieved, with a maximum lifting height of 14 metres. Wide industrial access doors enable large gearboxes, machinery, and plant equipment to be safely moved into the production area for assembly and subsequently prepared for shipment.
AYDINLAR DISLI & MAKINA and AYMAK CELIK undertake the engineering and manufacture of industrial gears, large heavy-duty gearboxes, planetary gearboxes, custom-engineered mechanical equipment, machine shafts, drive shafts, couplings, and critical spare parts. In addition to manufacturing new equipment, the companies provide gearbox maintenance and overhaul, reverse engineering, modernization of existing systems, and remanufacturing of critical components for which original engineering drawings are unavailable.
Engineering studies comprehensively evaluate the equipment’s operating conditions, motor power, input and output speeds, transmitted torque, service factor, dynamic loads, gear contact conditions, shaft loads, and bearing service life. During the design process, three-dimensional modelling, KISSsoft calculations, bearing-life analyses, and finite element analyses are used to verify the mechanical strength and operational reliability of systems before manufacturing begins.
Manufacturing processes include appropriate material selection, heat treatment, precision machining, gear cutting and grinding, dimensional quality control, controlled assembly, and functional testing. The objective is not merely to manufacture individual components in accordance with their engineering drawings, but to ensure that the entire system operates reliably and achieves a long service life under actual operating conditions.
Under the AYMAK CELIK brand, comprehensive engineering and equipment solutions are provided for bar and wire rod rolling mills and steelmaking plants. In addition to new plant projects, services include the modernization of existing facilities, capacity upgrades, improvements in energy and production efficiency, and enhancement of final product quality.
Projects undertaken by AYMAK CELIK combine process and plant engineering, mechanical design, equipment manufacturing, mechanical installation, electrical and automation installation, commissioning, performance testing, and technical support. Rolling mill stands, rolling mill gearboxes, flying shears, straightening machines, pinch rolls, roller tables, cooling beds, packaging systems, and plant-specific auxiliary equipment are designed and manufactured according to the requirements of each project.
Combining extensive experience in gear and gearbox manufacturing with plant engineering, custom machinery manufacturing, and field implementation capabilities, AYDINLAR DISLI & MAKINA and AYMAK CELIK continue to develop reliable, practical, and long-service-life industrial solutions throughout every project stage—from engineering and manufacturing to installation, commissioning, and after-sales technical support.
