DIY Custom car parts with a split mold urethane casting

I was spending hours producing these engine bay caps, so I decided to speed things up and make a silicone split mold and cast them out of a two-part plastic. Way less effort, time and even a stronger part!

My eyes transfixed to the screen my mouth hanging open I was about to drool when a garbage truck suddenly yanked me "back" to reality. So mesmerized was I by the sorcery taking place before me on the screen... You sir are a plastic wizard I I bow down and thank you for sharing this. Magic with the world. No for real that was fucking cool thanks

Lol, Thank you. I fail.... a lot too btw. The process is fairly difficult and what works for one part, does not at all for another.

Such clean work. Respect! I'm not familiar with PU as a 2 part casting resin. What makes it a good choice over the typical epoxies?

@EndMotive 8 күн бұрын

Thank you! I am by no means a chemical engineer, I just happened to grab something with an appropriate heat range and sent it lol. Epoxy resin would have likely worked just as well for this part.

Thank You. I just bought a used car with cracked interior parts everywhere. Do you think this method could be used to make a whole new dashboard?

@EndMotive Жыл бұрын

Yes in theory it could be done, but the cost of failure might not be worth it. The material cost for an entire dash would likely be too much. The small trim pieces would best be repaired with an epoxy or glue, and the dash itself maybe re-upholstered?

U actually used 3D printing 🤔

@EndMotive 2 жыл бұрын

Yeah for the master, but it takes less than 45 min each now vs the nearly 4 hours it takes to print. Plus the sanding and painting that isn't needed anymore saves even more time.

@brappineau4161 Жыл бұрын

did you need to vacuum these? have you had any issus with bubbles?

@EndMotive Жыл бұрын

I did have a some issues with bubbles, I should have added more or larger vents. Ideally they should be cast into the mold and then placed in a pressure pot.

Do you think this is possible to make a bumper mold with?

@EndMotive Жыл бұрын

Yeah I would think it is possible, but it would be a pretty complex mold and fairly expensive. Most aftermarket/body-kit style bumpers are made with a fiberglass molds. The silicone would be nice for weird or undercut geometry though.

Nice job 👍 first one that shows you can mold yourself without selling your organs for an injection molding machine 😂 Do you know how about the temperature resistance of the plastic? 🤔

Yeah, injection molds are crazy expensive. This plastic is good for 250f I believe, which is why I chose it!

Do yo need that vaccum thing for the silicon, is there a cheaper alternative? because i want to make some molds for my tools 😬

@EndMotive Жыл бұрын

Nope, You don't need a vacuum pot. It helps degas the mixture and reduce the amount of bubbles, but some silicones claim that they are low-gas and do not need to be vacuumed at all.

@jessechampagne5482 2 жыл бұрын

Could you not have just 3d printed the molds, sanded them, bunffed them and applied mold release? Serious question. Just thinking for those of us who have a 3 printer but not well versed in all the other stuff you did. This definitely a huge time saver if you are making multiples comparing to 3d printing the part everytime though great thinking.

@EndMotive 2 жыл бұрын

I could have sla printed the molds, but it would have next to impossible to sand them and texture them. Then the rigid molds would create a mechanic lock with the cast resin. It would have been possible if I added some draft angles and no texture though.

@jessechampagne5482 2 жыл бұрын

@@EndMotive if you print them in the right orientation so that your layer lines are for the most part laid in the direction of pull it will release much easier. Also a good layer of wax and release agent would help as well as using filaments that are naturally chemical resistant like PETG. You could also do the mold out of TPU if a hard mold would be too difficult to use. Food for thought. I just did a little digging and this is what I came up with thought I would pass it on.
