Splendid narration and great sense of humor.

Learnt a few tricks and corrected many mistakes.

Can you share expertise on shut-off surfaces and three or four part mold making.

Hi Ravi,

Thanks for your kind words!

Are you planning on doing some injection molding? That is the only instance I know of shut-off surfaces being used. That is not my area of expertise, but I can try and find the info you need if you can give me more specific about your project.

And regarding multi-part molding, that is a more advanced process that I'm afraid I don't have time to do justice to here. There is definitely a chance I'll make an advanced mold making class in the future!

In the mean time, here is a link to a well done instructable on making mother molds for multi-part molds that might give you some insight into parting lines and connectivity for multi-piece molds:


Happy making! and let me know if there's anything else I can help with.
