Hey ahhh, why these parts getting so soft in the sun?

 

How can I fix this? I do resin infusion, is it time to get a parts oven and switch to a higher temp tooling gel?



If Brute Force Isn''''t working your not using enough...

Hi Don,



Heat lamps, as Bruce suggests can be used by you should excercise caution because you can accidentally get some very hot spots which would be beyond the temperatures you can safely expose the resin to. If you use heat lamps or other very localised heating be sure to diffuse the heat through breather cloth or some other insulating material which will dissipate the heat more or even flip the mould over (if it's still under vac) and shine the heat onto the reverse side of the mould, rather than directly onto the part.

yeah you have to be careful with placement of the lamps ,the single is good for a small part/repair   i also have a larger multi  head where you can angle the heads independently of each other 
i use a thermometer to check the temp all over the part to find the hottest spot  (if it has one) relativly flat shapes tend to stay within a few degrees over the entire surface ,stuff with deeper shapes in it i tend to use the bigger lamp and try and angle it around the part so i get a more even spread of heat 
you gotta be careful though Smile
