Steel and aluminium closed-die forging
Extra Forge d.o.o. manufactures custom steel and aluminium closed-die forgings in small and medium series in Slovenia. We support industrial customers with material selection, tooling and subsequent operations according to project requirements. Send your drawing to discuss manufacturability.

We combine our family forging tradition with Industry 4.0 technologies. Our CNC 50 kJ forging hammer and 1000 t screw press support controlled production. We agree dimensional tolerances, inspection requirements and traceability documentation for each project, according to its material, geometry and delivery condition.
Our engineers support you from the first idea to the ready-to-install part. We help you choose the right material, optimise the geometry for forging and define tolerances, so you get a mechanically safe and economical design. We then manage tool development, forging, heat treatment, machining and surface protection (KTL, galvanizing, zinc coating, anodizing) under one control.
Our quality and environmental management systems are certified to ISO 9001 and ISO 14001. We use measurement and process records to check production against agreed requirements. Material, heat treatment, inspection documentation and any surface finishing are defined for each project. Energy use and process improvements are monitored as part of our environmental management.
Flexibility and a Complete Forging-to-Final-Production Service
Steel
Precision Steel Forging
We manufacture closed-die forgings in carbon, alloy and stainless steels, with net forging weights up to 4 kg. Small and medium series are made to your drawing. Material, heat treatment, dimensional tolerances and inspection requirements are agreed for the intended application.
Aluminium
Closed-Die Aluminum Forging
We manufacture closed-die aluminium forgings with net weights up to 3 kg, using 6082, 7075, 2014 and 2017 alloys. We supply small and medium series to your drawing. Alloy, delivery condition, heat treatment and finishing are selected for the component and its operating requirements.
Manufacturing program
From Concept to Ready-to-Install Parts
The company is a high-tech production company that strives for a comprehensive offer, quality workmanship, short delivery times and uses the latest machining and forging machines and introduces advanced technological production processes.
Industry 4.0
Measured, Documented, Traceable
Industry 4.0, also called the Fourth Industrial Revolution, refers to the current trend of automation and data transfer in manufacturing technologies.
Why Extra Forge
-
What do we do for you?
Extra Forge develops and produces steel, aluminium, copper and bronze forgings in small and medium series. Services include tool development, process simulation, machining, and surface protection (KTL, galvanizing, zinc coating). Technical support is provided throughout product design and optimisation. -
Why choose forged parts instead of cast or milled parts?
Forging can improve grain flow and mechanical performance. The result depends on the alloy, geometry, heat treatment and loading. We assess the production route for your component rather than promise a universal percentage advantage. -
Why choose Extra Forge as a partner?
Choose Extra Forge as your partner because we combine technology, reliability, and flexibility, with a response within 24 hours, short delivery times, full traceability, and technical support in development and product optimisation, delivering the mindset of a partner, not only a supplier. -
How do you ensure stable quality?
We use process monitoring, measurement and production records to check agreed quality requirements. The required inspection plan and traceability documentation are defined for each project.
