2 Cavity Compression Mould for coffee lid

Last crawled date: 1 year, 10 months ago

This is a class project. We were challenged to build a mould and die using the same shoe. The other teams are following along the assigned agenda. My group has decided to kick it up several notches. We decided to actually try out the part. A decision was made to make it a compression mold since no injection machine is availabvle. The blank part is 0.02 thick polystyrene sheet cut into a specific size. The blank is loaded into the job and held in place by a ring that clamps it in location. Next heat is added by a heat gun. When the plastic is drooping and soft, the two halfs come together using a verticle spotting press.

The second part is to trim the two lids from the plastic part. I am up to this point on the design, Dies are going to fit in the same pockets in the aluminm inserts and also uses the press to cut them out.

This set of tools will stay at St Clair college for them to teach their future CADCAM students about inovation and to showcase the program. Mould and Die training programs were cut a few years back when substancial work was offshored. Fortunately it is returning to the Mould Capital of the WORLD, Windsor Ontario rocks !!!

More updates as this progresses. I inteand to make a video of the tryouts and also some of th manufacting processes used. The job is entrely designed in NX8.0. ALL cutterpaths are generated using Mastercam X7 and cut on a Cincinati VMC 500 and a Robodrill. The other machines used will be drill press, Anilam controlled milling machines, and also Manual Lathes, Sink EDM and Robowire EDM
