This is an engineering show for engineers and product developers.

this is the best explaination of 2K, by the way, the Zwei Komponenten in German are perfectly pronunced.

[EzatezGreen]

This video helps me to better understand 2k PIM in a short period compared to google-read. Thanks Gordon Styles and TEAM who crafted the video, by far the best 2k PIM video for learners like me

[Hsilvag]

The quality and amount of content on this channel are amazing. As a plastic injection mould designer, its a pleasure to watch this.

[cptpowerpuff]

This is amazing, thank you ! How is this channel not more known?

[marknaglreiter]

Excellent job of explaining the processes.

[slipperyslope]

Incredibly informative and to the point.

[johnnycastro]

When i seen that mold turn on the moveable platten i was amazed lol ive only been in plastics for about 5 yrs and that shit was pretty damn cool lol

[Waku]

Amazing and informative video. Thanks for taking your time of your day to produce these.

[LYPeng-hj]

Thanks for amazing sharing，it's useful！

How are the surfaces to be covered during insert molding / overmodling isolated from those that cannot be contaminated by the injected material, e.g. a thread of motal threaded insert has to be clean after insert modling, so how it is made?

[noahhastings]

3:49 Hey, that's a thermopen! Love those things.

[chrisdaniel]

I need to fully encapsulate a steel bar in UHMW polyethylene, what is the best processes for that type of application? Thank you

[AShiftySpock]

About to embark on trying to insert mould toothbrush bristles onto a toothbrush handle for a client, both parts are to be injection moulded... We're using a bolster plate die set from Meusburger for use with insert plates, do you think it is possible to make the handle in on set of insert plates then the overmoulded bristle part in another, IM a load of the handles then place these into the second insert plate set that will IM the bristles on?

[marquisdaily]

Thank you very much, great content. I am wondering what the tooling and process would like in case of plastic overmolding on a steel part. For instance, on the Tesla Model 3 front suspension wishbone

What are the best practices for design-for-insert molding for say a power supply that has the electric contacts molded into the plastic (i.e. A Wall Wart)? I struggle to find information on how to design for this to accommodate 'holding' the metal insert so it properly creates the shuts offs and parting surfaces as expected, while not crushing/deforming the insert during mold close. Would be great for a video topic!

[glenmcneill]

In my experience the term insert molding is more of a catch all phrase for the process of overmolding.

[khj]

This video treats overmolding and two-shot as the same process, but I've found that tooling companies make a clear distinction between the two. However, for the life of me I cannot figure out the exact difference between these two processes and what shapes can be made with one process, but not the other.

[lisasnow]

has anybody ever used insert molding multiple parts? and how do you hold the insert into the mold

[harendratharu]

I have for 3 years experience injection moulding

Fascinating. Wanna work in star Rapid.
