We develop and manufacture sports components from carbon composites. Our focus is on injection moulding of polyamide-carbon composite (PACF) for bike frames – a lightweight and durable alternative to aluminium that enables sustainable, fast, and flexible production in Europe. We are the only company in Europe to offer the entire process under one roof: development, injection moulding, post-processing, and high-end painting. This allows us to provide a complete service to our customers.
Product and technologyProduct
COLORprofi Fiber specialises in the development and production of sports components using injection moulding of polyamide-carbon composites (PACF).
As passionate cyclists ourselves, we focus primarily on the cycling industry. PACF injection moulding offers numerous advantages for producing bike frames and other components:
- Production cycle measured in minutes (e.g. for a bike frame)
- Made from recycled and fully recyclable material
- Local EU-based production – independent of Asian supply chains
- Excellent balance of stiffness, weight, and durability with PACF
- Flexible, just-in-time manufacturing
- 100% repeatability and consistent quality of every part
- Unique design not achievable with aluminium or traditional carbon
Technology
The world is changing – and cycling must change with it.
At COLORprofi, we believe in European manufacturing: from recycled and recyclable materials, independent of Asia, just-in-time, and flexible.
Our way forward? Injection-moulded PACF frames.
Polyamide with carbon fibre. Advanced technology. Sustainability. Minimal waste. A frame in just 2 minutes. Moulding, post-processing, and painting – all under one roof in the Czech Republic.
How do we make bike frames from PACF?
Material preparation
PACF granulate (polyamide with carbon fibre) is dried and prepared for injection. We use recycled and fully recyclable materials from EU suppliers.
Injection moulding
The material is heated to the required temperature and injected under pressure into a steel mould. Precise shapes, cavities, mounts, and reinforcements are formed in a single step – with 100% repeatability.
Cooling and demoulding
The mould is cooled to allow the material to solidify. Once opened, the finished part is removed – typically by a robot. Complete cCycle time: approx. 2 minutes.
Post-processing and finishing
The part is refined through a combination of robotic and manual operations. High precision, clean edges, and preparation for assembly or painting.
Painting and surface treatment
The frame enters an automated paint line, where the final surface is applied (colour, lacquer, branding). From raw industrial finish to premium high-end coatings: wet or powder.
Quality control and shipping
All frames undergo visual and dimensional inspection before being prepared for delivery. All under one roof in the Czech Republic.
Certification
Our frames meet all European standards and safety requirements, just like traditional aluminium and carbon frames. We first test them in-house on our own test benches, where we deliberately push them beyond standard loads. They are then subjected to both static and dynamic testing in leading independent laboratories according to the EN ISO 4210. And we go beyond the typical 120 kg industry standard – our frames are tested for loads of up to 140 kg.
