AND SOLUTIONS
Gurit has worked with many high profile clients to design, develop, and manufacture wind blade production lines and tools to aid in the blade turning and turbine assembly process with high efficiency and accuracy. Gurits offer for molds provides:
- Plugs and molds
- Wind blade mold turning systems (hinges)
- Mold temperature control solutions
PLUGS AND MOLDS
Whether it is new design, concept, build to print design, or prototypes, Gurit can work through all the phases of a project from design conception, design & validation, manufacturing, to delivery of the final parts with a competitive cost and time without compromize to quality.
CNC MILLING
Gurit’s specialised CNC engineers operate 5-axis CNC machines, build master plugs with extreme accuracy and speed. Gurit’s plugs have successfully been used to produce up to more than 25 perfect molds. This means that all components, shear webs, spar caps and root inserts fit every time without costly adjustments or the need to use fillers.
HYDRAULIC EQUIPMENT
Gurit equips its molds with hydraulic turn-over, closing and clamping systems, jigs and fixtures, and offers a choice of software controlled electric or liquid mold heating systems depending on the production process or the targeted precision.
HIGH-STANDARD WELDING
Gurit’s plug and mold surfaces are held by a very rigid steel support structure to ensure a tight, stable surface geometrical tolerance. All welding is done in-house following ISO standards, with CE certified welders and international welding on-site, to ensure high levels of quality and safety.

TURNING SYSTEMS
POWER HINGES AND TURNING SYSTEMS
Gurit offers a full range of hinges with different capacities and arm sizes catered to blade mold sizes from 50 to 150 m.
The turning system can precisely close the two halves of the mold and control angular positions.
Gurit’s hinge portfolio includes arms with sizes and torque capacities ranging from 320 to 800 kNm. The latest hinge generation is modular, this enables a fast and low-cost installation, providing the ability to expand and reconfigure the system.
MOLD TEMPERATURE CONTROL
Whether it is new design, concept, build to print design, or prototypes, Gurit can work through all the phases of a project from design conception, design & validation, manufacturing, to delivery of the final parts with a competitive cost and time without compromize to quality.
ELECTRIC RESISTANCE HEATING SYSTEM
The wind blade mold is normally divided up to 450 zones depending upon the blade structure design. Heating ramps of up to 2°C/min
HYDRONIC HEATING AND COOLING SYSTEM
The patented liquid heating and cooling systems from Gurit are designed for further accuracy in the production cycle. Allowing for higher temperatures with a more uniform distribution, this design ensures an even cure on all parts.
MOLD SKIN COOLING SYSTEM
Cool air is blown through conduits attached to the back of the mold’s composite skin. This reduces the cooling time required to turn the half shells prior to closing the blade. Also shortens the cooling time to demold the finished blade without damaging the bonding lines. This system is also offered in a dual heating – cooling configuration.
CAVITY COOLING SYSTEM
Gurit’s blade cavity cooling system shortens the cooling wait time to de-mold the finished blades without damaging the bonding lines. The system extracts the hot air inside the blade’s cavity and exchanges it for chilled air. The system is offered in two configurations:
1. CAVITY HEATING & PASSIVE COOLING
During the cure cycles the system blows hot air into the blade cavity. During the cool cycles extracts the hot air and blows in room temperature air.
2. CAVITY HEATING & ACTIVE COOLING
During the cure cycles the system blows hot air into the blade cavity. During the cool cycles extracts the hot air and blows in chilled air.
