Blow molding 

Sir ur teaching style is unique and very effective on human mind . Great sir

very informative

I'm working with the local civil protection director to make a prototype of a torpedo style rescue floatation device to be donated and mounted on natural wood posts at our most historically dangerous beaches. These torpedoes are abusively priced ($150 USD), not available locally here in México and not available in all-natural materials but I'm working to change that. We need a local bioplastics supplier with materials well suited for this purpose with sheet plastic that can be manually heat-formed over a mold. And for a much larger scale impact, we need an estimate of the cost of mold that could be used with recycled plastics, bioplastics and biodegradable plastics also to injection mold them for us. If we can raise the funds to pay for the mold ourselves, the devices can be relatively very inexpensive which will make them very accessible and help save lives everywhere they're used.

Thanks sr for give us suitable information . I am student of plastic engineering and I am pursuing DPT course from CIPET .
