Foam cylinder with metal plate inside
Foam cylinder with metal plate inside
(OP)
I need to produce a closed cell plastic foam cylinder of height about 6 mm and diameter 2 mm. The trick is that we would need to insert a aluminium plate inside this cylinder (width 1.5 mm and height 4 mm).
I have considered two options:
1. Find a company that can put these plates inside the cylinder during their foam process
2. Use two half-cylinders and somehow combine (how?) the parts when the plate is between them.
I haven't considered gluing as we need to produce tens of thousands of these cylinders. If someone can guide me to a manufacturing company or process that can handle these requirements, it would help me a lot.

Must it be closed cell foam? How about say, PP or PE with a good dose of blowing agent in it? If so, could easily be injection moulded, either robot insertion of parts into a multi-cavity tool or manually (at added cost, I guess, unless low-wage area!)

I know a moulder in Sydney who already over moulds steel bar with foamed PP to encapsulate the steel to reasonably accurately controlled thickness.
I can put you in contact if you are interested.

They don't have a website which i balked at, but after visited their facility I can see that they're legit.
If you want something with a website, maybe check out Bergad.
