Infusion Moulding with a reusable silicone vacuum bag

This video was made as a collaboration between specialist silicone manufacturer Elkem and our sister company Silicone Composites Ltd.
This is a 'complimentary technology' when compared to RTM and traditional resin infusion and is suitable for some applications where other 'closed mould' processes are not practical or economically viable.
You can compare our other videos of this same dinghy being moulded using VRTM and conventional infusion with a disposable vacuum bag.

Excellent

Very clever

Hi, i've noticed all vartm show parts so far use glass mats. Would this technique work with fabrics, carbon or glass, or would permeability be an issue without flow medium ? Thanks

[@Compositeinteg1]

Hi AeroGarage, VRTM processes are fine using other fabric types such as Carbon, Aramids (Kevlar), Hemp etc. You are absolutely correct that factors like permeability need to be considered, understanding this before you construct you VRTM mould is crucial in order to manufacture components without defects. Permeability of the fibre and resin viscosity are just a couple of the factors we consider when designing our injection/ venting strategy. Thank you for your comment.

Hello plz tell me this type of is bag we used to to corbon pripreg debulking procss...what are the material required to prepare bags

[@Compositeinteg1]

Hi Ubedulla J, The bag in the video was manufactured using our 2 part platinum cure silicone system. We used reinforcement cloth in areas that needed some additional support. The resin runner and and vents are products that we can provide and have a few different configurations available. For further information please contact us directly at [e-mail] . Thank you for your comment.

Hello. How many copies possible to make until that silicon bag get damaged?

[@Compositeinteg1]

Hi Max, It is difficult to predict an exact number of cycles as this will depend on the type of resin being used, the complexity of the shape and the general care taken by the operator. However, we have many customers using this technique successfully and several hundred cycles are possible (using polyester resin) Have a look at this case study on our website. Between 250 and 300 are achieved in this application. siliconecomposites.com/production-success-with-silicone/

Hiii how i van but this mesine for make fiber boot

[@RePlayBoy101]

only works with small projects and projects without many complicated wrinkles

[@Compositeinteg1]

We're interested to know why you think this technique is so limited. We have customers using it very successfully at various levels of complexity and at different scales.

@@Compositeinteg1 It would be great to see a more complex shape, Love the product already

[@ericww1993]

How come? The silicone bag follows the complicated shape and wringkles, so it fits much much better than conventional nylon plastic vacuum bag. It saves time, and material.

[@RePlayBoy101]

@@ericww1993 you clearly didnt work with any complicated shapes

[@ericww1993]

@@RePlayBoy101 So just explain it why? We need explanation and proof instead of statement

Hi, I was wondering if there is a chance you can share an information I can hire professions to apply this technology in my company? I would appreciate if you could share your email.
