Even if I did not find it in your sortiment - perhaps you have some alternatives for us working with epoxy in environments without complete control. I.e. structural work in sheds without heating or smaller workshops where heating blankets might be very handy to get a controlled cure?
Hi Rolf, it depends what process you're following. We have resins which have better tolerance to lower ambient temperatures and certainly it's possible to undertake most composites processes in less-than-ideal ambient temperatures but there is always a compromise and usually that compromise is reliability; for example, if you do a resin infusion in a cold shed using a heat blanket to get some heat into the mould and resin then there's likely to be hot spots and cold spots - you might then find resin flowing faster in the warm areas and very slowly in the cold areas, resulting in a partial infusion. Ultimately, you might be better investing your time in improving the insulation and heating where you're working to at least achieve some modest level of control.
Question may be inaccurate i need info Does this model have openings for fresh air to be preheated and circulated by the fans, or does it rely solely on recirculating the existing chamber air and also the type of fan(is it axial) and heating element used.
The oven recirculates the air inside. It doesn’t draw in or vent air to outside. The fan is an axial fan. The element is a conventional electric ring element, similar to what you’d find in a conventional fan oven.
Hi ... we have two of your ovens, just newly purchased and have run a few cooks. We ramp up to 121deg c at about 3 degrees per minute, soak for an hour, and then try to ramp down at 3 degrees a minute until 60 degrees c . It says in the manual that it can control the ramp down, and we are finding that the oven can not cool down at that speed without cracking the door open, or it just holds temp. Is the oven and controller designed to do this type of ramp down with the doors closed? Cheers Paul.
The oven doesn’t have any forced cooling or ventilation and is well insulated and so there is a limit to the cooling rate that it can control (basically, all it can do is turn off the heating). If the cool down rate required is slower than the oven will naturally cool at (with the element turned off) then it can control it, if you need faster cooling then it has no way to achieve this. Opening the door is the obvious way to speed up the cooling but it would be important to switch the oven off (or set the target temp very low) for this phase so that you don’t accidentally get in a situation where the heating elements are working flat out to overcome the heat escaping from the oven. Over prolonged periods this can actually cause dangerously hot conditions directly above the heating element.
Hello. Very nice product. Is it possible to purchase the controller separately? I want to build a heated mould and looking for a good way to control it.
It would depend on the test. In straight compression or tension, you’d probably struggle to measure any difference. Interlaminar shear is the property most likely to improved by positive pressure consolidation so a 3-point bend test on a cured laminate sample might perform a few percent different. We plan on making a OOA vs Autoclave video later in the year where we compare the differences between the two processes but, in short, done right with the right materials the differences are quite subtle.
Hello I got a question , I got one of these ovens from the 1ste generation, and I love to work with them . But they are difficult to program with the old steering so i don't use it with the programmation function only in manuel mode , this steering is looking fine. Is there a kit available to upgrade the old steering?? Kind regards Tom
At the moment, we can only offer an oven of the dimensions of the OV301. In the future, it’s possible we will develop other, larger ovens, but for now this is all we have.
Haha, I don’t think a tutorial on oven building would make good general viewing! There’s no secrets to the process of course but I’d guess that if one was to try to make a similar oven the cost in materials and components alone would be much higher than the price we sell them for.
Sorry, missed this question when you posted it but for others wondering the same thing, you’ll find the oven, and price, here: www.easycomposites.co.uk/ov301-precision-curing-oven

This channel is literally a gift from god and I hope one day I can repay you for the knowledge you share with us!!! Thank you!!!!!
Hi Adrian, we really appreciate the comment! Just knowing that you are benefitting from our content is reward enough for us!
The US & Canada have split voltage/phase 240/120v . Nice oven!

Maybe stupid question, but is this and autoclave same?
An Autoclave is both heated and under pressure where this oven is just heated.
Hello. Very nice product. Is it possible to purchase the controller separately? I want to build a heated mould and looking for a good way to control it.
Unfortunately, we don't supply the controller as a standalone or separate item. Sorry for any disappointment.
What is the difference in strength between oven and autoclave cured prepreg on average? 10%? 5%?
It would depend on the test. In straight compression or tension, you’d probably struggle to measure any difference. Interlaminar shear is the property most likely to improved by positive pressure consolidation so a 3-point bend test on a cured laminate sample might perform a few percent different.

Hello Tom, unfortunately the oven control box is not upgradable, the internals of the oven and a lot of the components are different.
hello. I have an ov 301 oven with the industrial controller. Will the new touch controller work for my oven?

There have been changes in the wiring and casing, it's not possible to retro fit a touchscreen to an old oven.
if i want one but big size 2.5m w x 2m h x 2.5m
At the moment, we can only offer an oven of the dimensions of the OV301. In the future, it’s possible we will develop other, larger ovens, but for now this is all we have.
Your not going to show us how to make one :-(
How much is the prize
