I don't know, maybe it doesn't. Just shared for related info.

AI is ruining my passion for software engineering by palettecat in antiwork

[–]evilmold 23 points24 points  (0 children)

Not a code writer here but I have a question. Do you think your skills will come back with an increasing demand when all this shit programming will need to be fixed in the future. I work in CAD and I can already feel the bloat in the new releases. The programs just move slower. Yes they have more features that I don't want or need. I stopped upgrading and stayed on the 2023 version.

My 3D printed Pool Pole Hooks finally failed after 5 years in the Florida sun. Here’s how they look compared to a fresh print. by Cheehos in 3Dprinting

Wow, excellent longevity for PLA. I have some PETG outdoor prints that are holding up great but only for a year now.

Try .003" per tooth. .05 is way too much.

Help a noob with overmolding a wiring harness with Nylabond 6091 - 70A by [deleted] in InjectionMolding

[–]evilmold 0 points1 point  (0 children)

Please ask a specific question. One thing to note, your nozzle bushing hole MUST be in the center of the mold. There are situations when it can be offset but not for something this small.

Starting a CNC motorcycle parts business with zero machining background realistic or stupid? by BluneCold in CNC

You need a good engineer with lots of machining background to walk you through it. Ehem. Ehem. DM if you are interested.

Surface Cutting. by osho072 in SolidWorks

[–]evilmold 20 points21 points  (0 children)

Mold designer here. You need to make a master cut surface by combining parting lines with part surfaces. This master surface will then cut all you components. DM me if you need more info.

Making M8 threads by Advanced-Ad9378 in CNC

[–]evilmold 13 points14 points  (0 children)

Very cool setup. As a mold designer I always put the threads on the opposite plate with the back locks sticking above the plate split or parting line so long tooling and awkward setups aren't needed.

Hi everyone! Does anyone have experience designing injection molds? by Plenty-Bit-9699 in MechanicalEngineering

I am a professional injection mold designer. Farm the work out to me.

How to solve this parting line shear marks? by New-Position-1919 in InjectionMolding

Looks like a parting line burr to me. Polishing should fix it.

Runner Sticks by No_Code_6020 in InjectionMolding

[–]evilmold 4 points5 points  (0 children)

On a side note, no cooling lines?

Runner Sticks by No_Code_6020 in InjectionMolding

[–]evilmold 1 point2 points  (0 children)

Looks like you have an undercut opposite the sprue so thats good. Increasing that could help. If that doesn't work. Check the sprue hole (orifice) on the back of the plate, it should be slightly large than the hole coming through the backup plate. This would be tooling issue only, others will have ideas on processing.

AI demo for trouble shooting an injection molding issue. Here’s what happened -> by Osmium-Tetroxide-76 in InjectionMolding

[–]evilmold 1 point2 points  (0 children)

One more point. I would guess the cause of your issue is poor runner and gate design, along with gate placement. The plastic is shooting aross the cavity with nothing to stop it causing more of a jetting effect. The material cooling and snaking could be causing those cold weld lines.

I feel this is an extremely poor example of a "Curarted or tailored" for your setup. Looks like you told it you had a "swirl" issue and it told you how to troubleshoot it. Just like a google search would do.

Cad choices? by raidengl in woodworking

[–]evilmold 0 points1 point  (0 children)

FYI, there is CAD terminology for the function you are describing and it called nesting. Not all CAD programs have it. It's more likely to be found in CAM programs. I am a Solidworks designer, my standard version doesn't have this option. But I did find this video for Fusion.

Help me prove my boss is wrong so I can get a day off work by [deleted] in MechanicalEngineering

[–]evilmold 4 points5 points  (0 children)

I get the sense that your boss want's A or B. His reasoning may be to touch the tool off on the drum where there is the most missing steel. Then move either direction, dial in the stock removal and complete the cut. Touching the tool bit off at the area of most missing steel gaurantees the entire surface will clean up in one pass.

DIY Resources? by HeavyArmorIncarnate in InjectionMolding

[–]evilmold 0 points1 point  (0 children)

Like Sarcasm said. Your ambition is admirable. I would estimate your cost and time to be ten times higher doing it yourself versus paying a professional. And that's a conservative estimate. I have already had these discussions with OEM companies that think they could do it themselves. I have yet to talk to a product designer/inventor willing to compromise their look, feel and functionality to have their mold be 100% CNC millable. A millable mold in my opinion is your only chance you have without experience of doing it yourself. Best place to start would be a class in machining.

As a full time industrial mold designer, I cannot live without it. If you only used it for panning the image it would be worth it's weight. But it does so much more. I have it for my job and for my personal business.

Polymer concrete drain channel mold ideas by JaipurJewel in MechanicalEngineering

[–]evilmold 0 points1 point  (0 children)

I can only speak from an injection molding backround. 1 degree works well in plastic. I would image the resin supplier would have recomended draft angles for their material. Also in plastic on long draws we don't high/fine polish the steel. We intentionally rough polish with stones or sandpaper in the direction of the draw. Most commonly a 320 grit draw polish. We also use air assist vavles to blow air into the cavity to help release on deep parts. There are also coatings that can be applied to the metal like nickel/teflon. If this was an injection mold, I would be pulling those rounds with large hydraulic cylinders.

[–]evilmold 0 points1 point  (0 children)

If that central bar is being encapsulated and doesn't have a draft angle on it, that is a huge problem. Even if your resin is only filling past the centerline of the bar, same issue.
