china plastic injection molding part

we're making robots now,so the usa will get it's manufacturing back to save on the shipping cost.

@ plasticman3000: Sub gating would increse tooling manufacture time and costs as the fixed half would need machining. Also, sub gates, depending on the material being processed, often leave shaved gate debris on the tool face as they get worn, thus leading to possible surface defects via inclusions. A simple jig set-up would allow the operator to degate the part with accuracy and avoid the possibility of an auto-degated sprue falling on to a polished part during ejection.

To 2006scottw, who said it's bad practise to remove the moulding from the tool before the ejectors have retracted- you need to look at the moulding properly to realise why. There are core blocks at the top of the tool that travel forward with the ejectors so that they positively release the part and if they returned with the ejectors, they would trap the moulding so it couldn't be removed by the operator.

This type of work was previously done in the U.S., both the mold making and the production processes. Every time a mold was sent out for machining in China they made a copy for themselves. Our technology was pirated and we allowed it to happen, maybe we can all work at McDonald's together.

@beefspareribs Couldnt agree more.

do you do work for artists

[2006scottw]

hes reaching in before the ejectors have not fully retracted lol bad practice

[plasticman3000]

I believe that cooling the tool during your launch would be extremely crucial for dimensional properties. It is hard to tell from the video but i believe you need a longer ejection stroke to clear the part from the slide blocks, even if you were to incorporate automation. The bottom clamp on the non operator side looks very unsafe. If you were to sub gate the part, i believe it would result in a faster cycle time and less scrap from the part of operators trimming the gate.

Awesome. I like the sound of the machine too!

[pccheng88]

Why not plug the cooling

[cnmoulding]

because test to check part quality

so not add ,when run production for later

we add it.

actually all the mould should be cooling for production.

yes, good video for me, an industrial design student *^_^*

[windyman007]

Nice tooling.

[Dithulusutsamotho]

good video for industrial design students!
