Vacuum resin infusion.
We place the dry reinforcement in the mold, seal it with a vacuum bag and let the resin wet it out completely. It is the way to get large, light, good-quality parts without the cost of prepreg.
Large parts with a good cost-to-quality ratio.
Infusion achieves higher fiber content and lower emissions than hand lay-up, and needs neither an autoclave nor cold storage. It is ideal for panels, fairings, covers and large-surface parts.
We work with carbon fiber, fiberglass, kevlar and other composite materials, and combine fabrics, cores and local reinforcements according to the loads the part has to carry.
- Panels and large-surface parts
- Sandwich structures with core
- Short runs and prototypes
- Good finish on the mold side
A good mold makes a good infusion.
The quality of an infused part depends on the mold: vacuum integrity, surface finish and dimensional stability. We machine molds on our 5-axis machining centers and measure them before lay-up.
If you make the parts yourself, we machine the mold to your specification. If you want the finished part, we handle the whole process.
RTM
Closed mold, two finished faces and repeatability in production.
TechnologiesHand lay-up
Prototypes, one-off parts and complex geometries.
TechnologiesPrepreg and autoclave
3 × 8 m autoclave being commissioned, available per project; today we cure prepreg in an oven.
TechnologiesMolds and tooling
Molds and patterns up to 8 × 3 × 2 m, measured before delivery.

Send us your drawing or 3D model, and we’ll bring it to life.
We study your project with the same care you put into designing it, then send you a clear proposal covering process, lead time and price. Only have the physical part? We’ll scan it and take it from there.
What customers ask us most.
Infusion or RTM?
Infusion uses an open mold with a vacuum bag; RTM uses a closed, two-sided mold. RTM gives two finished faces and more repeatability in production; infusion needs simpler, cheaper molds and allows larger parts.
Infusion or prepreg?
Prepreg with autoclave curing gives the best mechanical properties. Infusion is more economical and allows larger parts; for many industrial applications it is enough.
How large a part can you infuse?
It depends on the mold. We machine molds up to 8 × 3 × 2 m and cure in a 4 × 2 × 1.8 m oven or, per project, in a 3 × 8 m autoclave.
Can you make just the infusion mold?
Yes. Many customers lay up at their own facility and order the machined, measured mold from us.
