Plastic Products and Mold Design

I recommend to go to GoProto.com and get the free demo models they offer. It has really helped me. I hope this helps. Good luck.

Hi Santa,

We should go for Prototyping only when we are confident that our calculations and design is right or we will end up with a lot of prototypes.

That's why I was seeking for a good hinge calculator.

Hinges are really a pain to work with. Sometimes everything is perfect in theory but when the part is injected it doesn't work at all... A little tip I can share is to always try to put the gate parallel to the hinge's line of movement, so the plastic flow across the hinge area without any major disturbances. And you can also try to create a little radius on the corners of the hinge, guiding the flow to a single path.

hi all....

what are hinges use in plastic product design?

Well, they are used in many products, such as shampoo bottle lids, cleaning product bottle lids, and so on.

Hi all,

There is a specific ratio of the hinge lengths at various positions as it rotates that needs to be considered while designing the hinge.

Can someone add to the subject?

HI sir,

Only the PP material will have the hinge property.

the hinge design will be made by considering the stationary half thickness and moving half profile.

If you post the deatils of your product let me share my ides.

Don't put less then 0,5 thickness, use PP with or without talc inside.

Also you can check/play the flow by software. It should be parallel flow in them mold.

Feel free post more details for your pb.
