The MTI® hose (Membrane Tube Infusion) is a cutting edge production aide developed to enhance the productivity, reliability and quality of industrial composite manufacturing processes utilizing the vacuum resin infusion technology. It completely replaces the sometimes complex as well as time and money consuming standard vacuum port system setup. The MTI® hose is based on a semipermeable membrane sleeve which supports air and gases to be drawn out of the bagged system while ensuring that the infused matrix material stays inside the laminate.
This technology offers a decisive impact on:
The fast and simple vacuum system setup reduces labor and material costs and provides the possibility to cut cycle time particularly with the serial production of larger products such as wind turbine blades or hulls.
The membrane technology reliably prevents that resin is drawn out of the laminate so that the calculated fiber to volume ratio can be realized precisely.
The closed hydraulic system makes it easy to adjust the compaction of the laminate from the resin inlet side only.
The membrane system is self-regulating in terms of resin flow which leaves less room for failure. There is no complex timing of clamping and opening different vacuum ports.
A resin catch container is no longer necessary which enhances the process safety, reduces resin consumption as well as it saves time and money for the preparation of the container and disposal of wasted resin.
The MTI® hose is extremely easy to work with. It is flexible and pliable so it can be routed along the profile of very complex parts.
