Thats a new mold, I have been doing this for 15 years. Never seen one that clean from Asia.

I have not seen a mold from another source besides Asia in 15 years. I get very good molds from them.

congratulations on the work, I believe that the guide pins of the extractor plate are a little worse than the closing face of the mold. And it seemed to me that it had plastic burrs on the product?

Good work, what are the bearing looking like things on base plate, because of them ejector plate not touching bottom

[@geoffcrumblin7505]

This is the first mould that I have seen in 60 years that has no machine locating ring, not sure how it is positioned in the machine. BTW, the moulding process is very poor, parting line flash, Cavity is overfilled, suggest moving switchover position to decrease the filling volume.

[@gazibuyuktas7673]

That is the comment which I was exactly looking for. It is unable to locate mold in screw axis without locating ring.

Is the main mould outer assembly an off the shelf item suited to your particular machine or do you have to scratch build that as well as the actual mould itself ?

[@jackielau2076]

Thanks for your comments,but we do not have equipment to avoid it

[@joshua_lee732]

I tear molds down for maintenance cleaning here in America. Here I am watching this. I love the attention to detail. You use a cheater pipe I use a hammer. My torque spec is two ooga boogas for little bolts and 4 for the big bolts.

Hey Josh, I'm needing a mold made for a simple small plastic piece. Can you recommend anyone please? thx

[@ngocluong7839]

it's a nice video but i'm wondering if you forget to put some springs there to make the ejector plate back to its position or you have other way to get that plate back? as far as i know, you will need springs to push the ejector plate back. you can use pneumatic or hydraulic, but i think using springs is the easiest way to do that

[@jackielau2076]

we use screw to connect machines,it is safer than spring.Thank you for your comments!

[@geoffcrumblin7505]

Machines with hydraulic ejection connect direct to ejector plate. This doesn't require die springs. Much safer and less energy required. Yes, springs are easier but lazier.

[@newmovies1264]

Really nice system

[@максимдряпин]

how was a centering of plates in halves realized? There is no any pins in a mold - only screws, why them weren't necessary?

[@jackielau2076]

use mold base frame with accurate machining,thank you!

[@максимдряпин]

@@jackielau2076 but what about an assembly inaccuracy? I mean screw holes and screws are usualy made with a gap, so a plates may displace from one another during an assembly

[@jackielau2076]

​@@максимдряпин this is why we use precise machines to machine the spare parts of mold.it make sure assembly accuracy within 0.01 mm

[@giedriuscepas1583]

@@jackielau2076 I disagree with you. You are fixing mold's moving half to machine by clamping back plate, which means after long working, beams and core holder plate can slip down by clearance of hole and screws.

tooth brush are made by injection molding.but brush planting is very important process,I suggest you to find a professional toothbrush supplier

[@001FJ]

Generally speaking, a mold is for plastic, and a die is for steel. If you are injection molding plastic then you need a mold (aka "tool"). If you are stamping steel then you are using a die.

over all an efficient video- but over "Torqueing" the cavity in top half. (looked to be around a 3/8-16 takes only 25 foot pounds to seat properly) , also aluminum dents look small dead blow or soft copper . lastly as a procedure build all molds with an A/B strap to stop separation on loading in a machine. (google mold safety straps for an idea)
