    Metal Plastic
AI Thread Summary
To create a plastic cover that completely encapsulates a piece of metal, several methods can be considered, including 3D printing, which allows for custom shapes that fit snugly over the metal object. The desired outcome is a smooth plastic surface that conceals the metal entirely, without the need for a closure mechanism, as the cover will be terminally closed. The metal object weighs approximately half a pound. For durability, options like Plasti Dip, which is designed for tool handles, or powder coating are recommended, as they provide a robust finish. An alternative method mentioned involves dipping the hot metal into toner from photocopiers or laser printers for a quick coating solution.

Hi, I want to cover this piece of metal (A) with a plastic cover (white line B) that fits but I am not sure how that is created...do I need 3D printing?Has to be like an encapsulating plastic box that fits, hiding the underlying metal thing seen in the picture A...so the results is a smooth plastic surface, hiding completely the metal underneath...Does anyone know how this is done?

Out of curiosity, what is that metal thing? How heavy is it?

Do you want the casing to completely cover it with some sort of closure mechanism? Or will one end be open for inserting & removing the metal object?
 
its about half a pound. I want completely cover , closing mechanism not needed. I want terminal closing. Does not need to open for inserting & removing the metal object.

Just how hard and durable does the coating have to be? Perhaps something like Plasti Dip (https://plastidip.com/applications/), intended for tool handles, might work in your application?
 
Some time ago I posted this Raspberry PI DIY Mass Spec using Raman Scattering. It's was something of a cumbersome project though, needing a 3D printer and special heat-resistant plastic giving of carcinogenic fumes during printing. To be blunt it was also not very mobile and interpreting the results was further cumbersome Recently though, I've been told that Arduino, and it's various sensor packages, has matured to the point where it's a usable alternative. Now I realize that a cigarette...
Thread 'Nonlinear rubberband type thing - "k" dropping fast as it is stretched'
What materials can I try in order to get a curve of displacement versus force that looks somewhat like this.. (of course, there would be a small kink around the origin where the ends of the rubberband are closer together than its length, which is not shown here). I am looking for something that will last at least 100 stretch cycles and is not messy, so for example liquid based colloidal stuff won't be suitable. Is there something one can whip up using silicone and some additive, say? Or...
