Hi all,

I have just purchased my first kits from easy composites. Thanks guys for the training videos, they are very simple to understand.

In making my first part I have experienced a couple of issue and would like to understand where I went wrong.

1.  I used MDF to make my mould, I apply several coats of wax and PVA release agent but could not release the MDF part from the mould, what did I do wrong, did I need to spray the MDF part first?






2.  I had some issues with moulding my carbon part due to the tight spaces and complexity of the part, would I be better off using the vacum method for this part?














Many thanks,




Matt

Thanks for the tips guys.

I tried making the mould again but had the same releases.  I sprayed the mould with 2k primer and used the the easy lease and wax. The mould was really stuck this time, I ended up cracking the mould!

I think the issue is the sharp returns I have on the mould.  I am going to try re-making and reduce the overall depth of the part see if this helps.

I will post the results soon, work keeps getting in the way of fun stuff...
