Over 30 years of expertise. High-precision aluminium profile (extrusion) dies for solid, hollow and port-hole profiles. Scroll to explore the die from every angle.
Machined from H13 / 1.2344 hot-work tool steel, every die plate carries its profile geometry with micron-level wire-EDM cutting in hardened steel.
A real KALEKS porthole die: metal enters through the mandrel's four ports, welds under the bridges and exits the cap as a hollow profile. The complete stack is machined in-house.
Correct bearing lengths, balanced flow, right-first-time profiles. Send your drawing and let your die flow.
The journey of precision starts in orbit and ends inside a die in Gebze. Scroll down through the layers of Türkiye's national production.
From UAVs to fighter aircraft — lightweight, durable aluminium profiles serve inside every national platform in the sky. The dies that shape those profiles are our craft.
±0.01 mm · H13 / 1.2344 · CNC + EDMFrom armoured vehicles to electric cars — the land leg of national production is also built on aluminium profiles. Defence-grade die engineering works with the same discipline at every layer.
That die is made here. We are ready to bring over thirty years of experience and an archive of 40,000+ profiles into Türkiye's defence and aerospace supply chain.
On this journey founded in 1996 and now led by its second generation, KALEKS A.Ş. holds over 30 years of deep-rooted experience in aluminium extrusion die design and manufacturing.
At our high-technology facility in Gebze, Kocaeli, we produce high-precision extrusion dies for solid and hollow aluminium profiles. From design to CNC machining and from wire and sinker EDM to final inspection, we carry out every production process in-house within an integrated structure. With an extensive archive of over 40,000 profiles and our digital die management system, we deliver custom, consistently high-quality solutions for every geometry.
Beyond our expertise in extrusion dies, we extend this precision manufacturing capability to the defence and automotive industries, producing qualified mechanical parts, jigs and fixtures for these strategic sectors.
Using H13/1.2344 tool steel and rigorous quality control, every die leaves our facility perfect.
Our 18-machine capacity and integrated production flow allow us to offer competitive lead times.
We extend our CNC and EDM capability to precision component manufacturing for the defence and automotive industries.
Since 1996 we have manufactured profile dies for Turkey's established aluminium extrusion companies. Our dies produce profiles for the domestic market and for export to Côte d'Ivoire, Algeria, Azerbaijan, Kazakhstan, Iraq and Tunisia.
Complete die sets — die, bolster, feeder plate and backer — for solid, hollow and semi-hollow profiles.

When you need an aluminium part, we take on the whole process: we design the part for extrusion, build the die in-house and have the profile pressed at extrusion partners we have worked with for 30 years; we then cut, drill and machine it into its final form and deliver it.
Your part is engineered for extrusion; section and tolerances are agreed together.
We build the die in-house — 30+ years of die engineering.
The profile is pressed at our long-standing extrusion partners.
Cut, drilled and CNC-machined into its end-use form.
You receive a ready-to-use part.
We know from the shop floor which profile should run on which press. You deal with a single supplier — and receive a part that is ready to use.
