Hello,

Does anyone have reccomendations for molders/labs that will run some plaque tests for us?

We're looking to make a product using a combination of TPU and either PC, PC/ABS or PC/ASA but are looking to verify material compatibility before opening the tool.

We would provide the materials and would hope to have various combinations 2K/overmolded into coupons that can then be mechanically tested for material compatibility. Tests would include Peel, Shear and Lap testing.

Ideally the lab would be located in UK or EU, but open to further afield too.

Cheers everyone!

Hey everyone, as it says in the title..

If anyone is looking to sell one of those three in the UK I'd love to hear more about specs, use and price.

Cheers!

Hi all,

I've had regular flare ups on my eyelids since I was a kid (about 30 years). Always used steroidal cream as the doctor recommended, but learned a couple of years ago that this is not advisable.

Since then I've been trying to manage it with various daily/nightly moisturisers, and recently was prescribed Protopic.

It works very well, but I've found one potential negative side-effect that I wanted to see if others have also experienced.

My cycle goes like this:

Flare up > apply Protopic at night > intense itchy burning all night > feels less itchy but swollen the next day > apply a smaller amount on night two > completely healed on day 2 but with flakey dead skin shedding off > super smooth healed eyelids day 3

Obviously this is pretty great, but I have found since using it that my eyelids are super sensitive to any amount of sun exposure, even wearing polarized sunglasses. They feel very hot and will always flare up again after even a short period in the sun.

This didn't really happen before - I used to sunbathe for hours even without sunglasses on with no issues.

With it being eczema, I'm aware this could be a million other things, but thought I'd check on here as you're such a well informed bunch!

Hi all,

I'm not sure if this is the right place to post, but I saw a post about prototyping the other day and thought there might be some relevant knowledge on here.

I'm not an injection molder but have worked a fair bit on plastic component development over the last few years. We've always opened steel tools even for low-volume parts and even prototypes. It strikes me as very wasteful if the tool isn't being used to produce hundreds of thousands or millions of parts, and so I wanted to hear the community's thoughts about typical prototyping workflows.

I'm aware tools can be made in aluminium or even high-temp plastic, but for some reason our molding partner has always been reluctant to do this. Any thoughts as to why?

Something that may complicate it slightly is that we're looking to make overmolded or parts which combine soft TPU with a rigid polymer component, and we're targeting a strong chemical bond (the parts will be used to seal a pressurised vessel, so the bond must be airtight even at pressure). Would you always open a tool to test the part geometry from the start or is there a generic tool simply to test material compatibility?

Any advice on how best to prototype this kind of part in a cost-effective way is much appreciated!

Hello Swedish Spurs fans,

I was going to be watching the final game of the season at the stadium, but unfortunately have been forced to travel for work on that day. Fortunately I'll be in lovely Stockholm!

It would be great to watch the game in a dedicated pub with like-minded Yids, unsure if this actually exists in Stockholm but let me know if so!
