The material is PPSU, go look it up, and it has a high fill glass fiber content. And 10 % is considered high fill, all this information is listed on the parts if you know how to read it and you're good with polymer science.
Let OLDFART mans'plain some shit to you :;""?'s
I will keep this simple for the gender confused.
When people say "plastic" they are thinking about what they have seen "melt", this is the first type of material is called thermoplastics, they are melted and formed into a useable shape, they are plastic weldable and heat repairable, maybe glue-able, and can be melted into something new (recyclable) but the material changes a little bit each time so this is why you see "Virgin" listed on parts as a sign of first melt high quality part, think OEM.
Second type is thermoset materials, they look the same but they do not melt into soft flowing goo to be reused. They just turn into a chunk of chared smoldering carbon pile, like an old rubber bushing you're burning out. The material can be formed 1 time and then it is permeant. It can be recycled by shredding and used as a filler in another part, think used tires.
Most of all the parts you see in daily life fall into these 2 types of plastic and how do you tell them apart? The burn test. Get it hot and see what happens, does it melt or does it expand and char? I grew up on the shop floor of my buddies injection molding shop and watched the engineers reverse design some part and the first thing was the burn test when someone brought in something to be copied and with experience they could even tell the exact resin used by the smell, ask BLK54 about this he works in the manifold injection molding job, that smell is burned into his brain.
Now we get to what Ford used and on the manifold, they tell you..PPSU>10GF
PolyPhenoleneSulphoneUrea>10%GlassFillled. I'm boring you now so the short answer is heat will not do it, epoxy will but it will have to be the right type because most are too hard. This will work :

Sorry if this is overkill to your question, I am not an engineer. I am a high school drop out addled by drug abuse BUT ..I started a company with 160 employees around the world in cutting edge medical manufacturing by starting out on the shop floor and having an interest in the WHY of things.
