Here in uk it's called twinshot or overmoulding.
The first part, minus the overmoulded bit, stays in the tool, tool indexes and second material is injected in to fill the gap.
If you are specifying materials, make sure they are compatible to ensure good bonding.

If I were you, I'd just give up hope altogether.
You'll feel much better and by giving up hope you won't die in despair...
I'm not sure if Facebook has ever caused the lame to walk, but it has surely caused the dumb to speak.
Have a look at transparent amorphous Nylon 12. It's used for bowls for air line oil seperators etc.
Doesn't suffer from ESC. Excellent chemical resistance.

Polypropylene is a semi-crystalline material.
Tolerance tables look ok. Sort of generalised.
What is the variation in size which would be acceptable? (As a %age)
Have you checked the comparative material costs of your choices?
Nylon 12 has low water absorption and outstanding chemical...
On a bigger scale, I have seen a cnc pipe bender in operation.
The pipe was held in a collet chuck and indexed forward to a former and a hydraulic ram put bend #1. Pipe rotated and indexed forward for bend #2 and so on. There was also a saw station to cut the tube at whatever angle required...
Our local council have just started repairs on a local bridge. (Northumberland, UK).
It's only 400 yrs old this year.

I always understood that sulphur dioxide (as emitted) from volcanic eruptions caused global cooling?

I am thinking the same as you: that the hot tip is out of line to the gate. Tip might be damaged or a piece of debris (swarf?) Stuck in.
I'm assuming it's only one cavity is a problem?
Try some short air shots and see if the flow is going off square to tool. Cover the tie bars and moving half...
I'm surprised there's a worm and gear! Thought they went out in the 50's!
I'm with Greg. Blame the robot who was supposed to add grease.

Just had a thought. A glass reinforced impact modified PA6 would be ok. E.g. Du Pont ST801 is an unreinforced grade. Others are available.

You should check the cost of PAI before you get too excited. It also requires post-moulding curing.
An ideal material would be a glass reinforced TPU. Great wear resistance, low temp impact, chemical resistance.
Note it's not cheap, and needs vacuum drying before moulding.

I've always assumed times are local times. (I'm in the UK)
You could be correct. Timestamp on this post is GMT/UTC.
