KFUPM DeepTech Venture TRL 5
We replace the autoclave with adaptive electromagnetic induction — heating the resin from inside the laminate, and holding the cure profile uniform across the whole part.
The bottleneck
The material science moved on decades ago. The oven did not. Everything downstream of layup still waits on a thermal cycle designed around heating a room, not a part.
Autoclaves and thermal ovens raise the temperature of an entire pressure vessel to cure a component that may occupy a fraction of it. A single cycle can run up to 48 hours.
The consequences compound: throughput is capped by oven availability, energy cost scales with chamber volume rather than part volume, and adding capacity means adding capital equipment and floor space before a single extra part ships.
An alternating electromagnetic field couples directly into magnetic nanoparticles dispersed through the resin. Heat is generated inside the laminate itself, so nothing is spent warming air, tooling, or steel.
Because the cure is instrumented rather than assumed, the system can respond to what the material is actually doing — holding a uniform profile across varying thickness and geometry instead of running a fixed recipe and hoping.
How it works
Induction supplies the energy, sensing describes the state of the resin, and the control model reconciles the two — continuously, for the duration of the cycle.
01 / Induce
An electromagnetic field is applied to resin-infused laminate containing magnetic nanoparticles. The particles dissipate energy as heat exactly where the resin needs it, with no thermal mass to bring up to temperature first.
02 / Sense
Embedded sensors track temperature, magnetic field strength and resin viscosity throughout the cycle, so the degree of cure is observed directly rather than inferred from elapsed time.
03 / Adapt
The control model adjusts power and frequency as the cure progresses, compensating for thickness, geometry and local variation to keep the profile uniform from edge to edge.
Advantages
The point is not a faster oven. It is removing the oven from the critical path so that cure time stops governing how much a line can produce.
Cure times measured in minutes rather than hours release the throughput currently locked up waiting for oven capacity.
Energy goes into the laminate instead of the chamber, cutting both operating cost and the emissions attached to every part.
Every cycle is instrumented, so cure quality is recorded as process data rather than assumed from a fixed schedule.
Designed to sit inside an existing line and scale by adding zones — no pressure vessel, no new building.
Replacing autoclave cycles with localised curing removes one of the most carbon-intensive steps in composite production.
Lower capital intensity makes domestic advanced-materials manufacturing viable at smaller volumes.

Applications
The process suits epoxy, polyester and vinyl ester systems reinforced with carbon or glass fibre — the material families behind most structural non-metallic parts.
Structural components where cure consistency is a qualification requirement, not a preference.
Non-metallic pipe, spoolable line and corrosion-resistant equipment produced at length.
Lightweight body and chassis parts at the cycle times volume production actually demands.
Wind blade shells and spar caps, solar mounting structures, and filament-wound pressure vessels for hydrogen storage.
Storage tanks, cladding panels, composite rebar and pultruded structural profiles for corrosive environments.
If the part is a thermoset composite, the process is worth assessing. Send the geometry and your current cure schedule.
Discuss a partCapabilities & partners
Induction is our own technology. Around it we work with specialist partners across the rest of the chain, so a non-metallic structure can be built, joined in the field and inspected in service without the process being handed between vendors who have never spoken.

The same coupling principle as the curing cell, applied to reinforced thermosetting resin pipe. A coil and aligner bring the joint itself up to temperature — no furnace, no open flame, and the bond made where the pipe is laid rather than back at a shop.

Questions
The things manufacturers, researchers and investors ask us first. Anything not covered here, just send it over.
Thermoset systems — epoxy, polyester and vinyl ester resins — reinforced with carbon or glass fibre. The resin is loaded with magnetic nanoparticles so that the electromagnetic field can couple into the laminate directly. Suitability for a specific layup and resin system is something we assess as part of a pilot.
Embedded sensors report temperature, magnetic field strength and resin viscosity while the cure is running. The control model uses those readings to adjust power and frequency as it goes, which is what allows a uniform cure across changing thickness and geometry rather than hot spots at the edges. Because the cycle is measured rather than assumed, each part carries a process record.
TRL 5. The concept has been validated with a working prototype under controlled laboratory conditions. We are now working toward TRL 4–5, which means demonstrating a multi-zone cell on representative parts in an industrial setting. 4NMx is supported by the KFUPM DeepTech Venture Program.
That is the design intent. The system is modular and does not require a pressure vessel or dedicated building services, so it is meant to sit within an existing workflow and either complement or replace oven capacity. Integration detail depends on part size, geometry and takt time, which we work through during pilot scoping.
Two places. First, energy is delivered into the resin rather than into air, tooling and the steel shell of a chamber, so far less of it is wasted. Second, the cycle itself is far shorter, so there is less time for losses to accumulate. Our target of up to 90% is modelled against equivalent autoclave cycles and will be confirmed against measured pilot data.
We are looking for manufacturers with a real curing bottleneck, research partners in materials and process control, and investors backing deeptech at this stage. A pilot normally starts with a scoping conversation about your part family and current cycle, followed by lab-scale trials on your material before anything is built. Send us a note and we will set up the first call.
