01Capabilities
Everything a composite part needs, in-house
Ten connected capabilities, from engineering and prototyping to tooling, laminating and precision machining.
All capabilitiesEngineering & development
From requirements and CAD to scanned geometry and functional prototypes.
Engineering
Composite design, material selection and FEA analysis for parts that perform.
Prototyping
Fast physical prototypes to test form, fit and function before tooling.
3D Scanning
Accurate digital geometry for fitment, inspection and reverse engineering.
Reverse Engineering
Turn existing parts into producible — and often lighter — composite components.
Composite manufacturing
Carbon fiber parts, infused laminates, sandwich structures and the tooling to produce them.
Carbon Fiber Manufacturing
Custom carbon fiber parts, from one-off prototypes to production series.
Resin Infusion
Vacuum resin infusion for consistent fiber-to-resin ratios, thorough fiber wet-out and low-void composite laminates.
Sandwich Panels
Custom carbon sandwich panels with PMI or honeycomb cores and integrated inserts for mounting and load transfer.
Tooling & Molds
Composite molds and CNC-machined tooling for prototypes and series production.
Machining & cutting
Large-format CNC milling and dual-head waterjet cutting for composites and other materials.
02How we work
From concept to production, under one roof
Engineering, tooling, laminating and machining happen in the same facility. That keeps decisions close to the people who make the parts — and keeps your project moving.
Step 01
Engineering
We review requirements, loads and geometry, then develop the design with 3D modeling and FEA analysis — selecting the right materials and manufacturing method.
Step 02
Prototyping
Where an existing part is the starting point, we capture its geometry with 3D scanning, develop the CAD model, then use 3D printing and precision machining to create prototypes for fit and function testing.
Step 03
Manufacturing
We build the molds, then laminate using resin infusion and CNC or waterjet trim every part to its final geometry.
Step 04
Production
Validated parts move to repeatable production — from small batches to series — with dimensional control at every stage.
03Why X CarbonTech
One partner from first sketch to series part
Fewer hand-overs, faster decisions and one team that is accountable for the result.
- 01
Everything under one roof
Engineering, prototyping, tooling, laminating, machining and inspection in one facility — no chain of subcontractors.

07Quality
Controlled from fabric to finished part
Quality is built into the process, not inspected in at the end.
Our approach to qualityStep 01
Material selection and incoming inspection
Materials are selected for the application and checked on receipt. Documentation requirements are agreed at the quotation stage.
Step 02
Controlled processes
Resin infusion, molding and CNC finishing follow defined steps for repeatable results.
Step 03
Dimensional control
Parts are checked against the design geometry, from first article to production.
Step 04
Surface & finish
Visible parts are inspected for weave uniformity and surface quality, matte or gloss.

Frequently asked questions
What do you need from me to prepare a quote?
Ideally drawings or CAD files (PDF, STEP, IGES, STL, DXF or DWG), the required quantity, material or finish requirements and your timeline. If you have no drawings, a sample part or photos with key dimensions are a good start — we can 3D scan the part.
Do you make one-off prototypes as well as series parts?
Yes. We produce single prototypes, small batches and series production — and the same team supports your project through every stage.
Can you reproduce a part without drawings?
Yes. With 3D scanning and reverse engineering we capture the existing part, rebuild it in CAD, adapt it for composite manufacturing and produce it in carbon fiber.
How large can the parts be?
Our 4-axis CNC mill has a 3 × 2 m work area and our dual-head waterjet a 3 × 1.5 m cutting area. Tell us about larger parts and we will check what is feasible.
What tolerances can you achieve?
Machining accuracy can reach 0.05 mm, depending on the material, geometry and manufacturing process. We confirm the required tolerances for each part before production.
Which materials do you work with?
Carbon, aramid, glass and hybrid fabrics; PMI foam, Nomex and aluminum honeycomb cores; epoxy resin systems. We also machine aluminum, plastics and foams.
Do you work with customers outside Bosnia and Herzegovina?
Yes. We work with customers across Europe, the U.S. and the Middle East. Delivery terms are agreed with each project.
Can I buy composite materials from you?
Yes. We supply carbon and Kevlar® fabrics, epoxy resins and hardeners, core materials, chemicals and production tools.
Have a composite part in mind?
Send us your drawings, a sample or just an idea. Our engineers will review it and get back to you with a clear path to production.
