Injection Molding 101: Draft Angles

Draft angles allow for removal of the plastic from the mold. Without draft angles, the part would offer significant resistance due to friction during removal. Draft angles should be present on the inside and the outside of the part.
The deeper the part, the larger the draft angle. A simple rule of thumb is to have a 1 degree draft angle per inch. Not having enough draft angle may result in scrapes along the sides of the part and/or large ejector pin marks (more on this later).

You have made it as easy as it gets to explain. Thank you for the great demo !

[@JayconSystems]

You are very welcome! 🙏

[@instneha9196]

Wow...what a quick explanation u hv provided ... keeping making more videos on technical topics pls .
Thank u

[@JayconSystems]

We will. You're very welcome!

Not to mention the vacuum issues, with correct drafts you will release the vacuum instantly when the core is moving away

Very nice buddy...keep going

[@JayconSystems]

Thank you!

wait wait wait, if you taper it, your casting will change it's shape, then you will have to apply additional surface finishing and cutting operations. So, isn't it in turn making the process even worse?

please make video on locators

Nice sir

[@JayconSystems]

Thank you!

cool! What's the desired or minimum draft angle for proper mold separation? I'm making models that have thickness around 1mm. I don't have too much wiggle room, would 1degree be enough?

[@NotechisMusic]

Don't know if you still need this information, but 1 degree would be fine. Typically angles between 0.5 and 2.5 degrees are normal.
