House of Composites are using a wide range of manufacturing processes from which the most suitable will be selected to maximize the output.
|Vacuum Infusion (VI) is also known as Resin Infusion, VaRTM, SCRIMP etc. VI is a modern and reliable one-sided manufacturing process which is able to generate consistent and high quality parts at reasonable costs. The tooling investment is also reasonable low as it is a one-sided tooling concept with a flexible and replaceable plastic bag as B side. It is a closed process so VOC can be reduced to almost zero.
Vacuum Infusion benefits
- Repeatable process
- Low cost materials compared to prepregs
- Much larger material possibilities compared to prepregs
- Easier lay-up due to higher fabric drapeability compared to prepregs
- Visual processing makes it easier to perform QC
- Oneshot processing of sandwich structures with closed cell core
- Medium high fibre volume fraction of 45-55%
- No limitations in size (Used for big boat hulls and wind turbine blades)
|HOC have in-house tooling facilities including CNC machining.
||Tools for composites manufacturing are produced of a large range of materials and concepts selected for the specific application, where the following criterias among others are evaluated during the tool selection evaluation:
- Number of prints
- Temperature cure cycle
- Surface quality
- Accuracy during tool manufacturing
- Accuracy during processing due to thermal expansion (CTE) and resin shrinkage
- Vacuum integrity
- Tool stiffness, strength and stress
The majority of tools are made out of machined metals or composite materials with or with-out internal heating, but for prototypes and zero series tools can also be machined directly in low cost tooling boards.
