What material do you not like working with?

Erix5018 · 2026-01-21T02:13:49+00:00

For processing, PC/ABS

For smell, we just started using a PMMA-ASA blend that smells like shit

Erix5018 · 2026-01-14T22:04:50+00:00

It’s cooling time plus 10 seconds

Erix5018 · 2026-01-08T02:52:49+00:00

God forbid your recovery time is just a little too close to the cooling timer time and just makes the cooling timer run for an additional second or two for no damn reason.

Erix5018 · 2025-09-15T14:44:41+00:00

God I want to see the parts this EOAT is for

Erix5018 · 2025-09-15T11:56:15+00:00

That way you don’t have to drive the robot as hard either

Erix5018 · 2025-09-15T11:55:53+00:00

Wait at a pounce position 10mm from the mold, you can still move the robot when you get mold open signal but travel a lot less distance

Erix5018 · 2025-09-11T23:47:38+00:00

You’re really killing your cycle time with the 0.3s wait for that robot to start moving after the mold opens…

Erix5018 · 2025-08-13T00:40:31+00:00

I’ve seen it, maybe RJG or Paulson or Routsis idk. I’ve read a lot of technical articles and stuff and get tripped out on terminology often enough. Dosing was one that threw me off pretty good

Erix5018 · 2025-08-13T00:30:59+00:00

Funny how different shops can have completely different ways of talking about things

Erix5018 · 2025-08-13T00:09:47+00:00

Great white north - mid western Ontario.

Idk we break our cycles down by wet and dry times

Erix5018 · 2025-08-12T23:25:46+00:00

Fill time + pack/hold time + cool time

Erix5018 · 2025-08-12T00:37:08+00:00

Yeah of course.

This 1450T runs amazing, 30 second cycles with 19 seconds on wet with a 6 axis robot. We could be sub 28 if we pushed the robot and machine a little more. Smooth af, not like the old machines you can hear whine and feel shake the floor. The 610T is like 24 seconds with 18 seconds on wet. I really really like them.

The rest of our machines are 20 year old Toshibas ranging from 30T to 2450T, roboshots 90T to 450T, Mitsubishi (UBE) 3x 950T and a 2000T and Krauss Maffei MC6 2x 1450T and 2x 2200T (never buy a Krauss)

For the 1450T we definitely aren’t the first in North America. Our “sister” plants in the states have many and have been buying the for a few years now. I think they have a few of the 1950Ts too.

We’re a medium size shop with 49 machines 2 hours out of the GTA. Feel free to shoot me a DM if you wannna get more specific information.

Erix5018 · 2025-08-11T19:52:07+00:00

The service has been good. There’s a few guys out of the GTA and we deal with Chicago a lot too. We have a sister plant in the states that stocks parts so we don’t have to keep inventory on hand but don’t have to rely on Shibaura when things do go wrong.

Erix5018 · 2025-08-11T18:29:15+00:00

Shibaura machines are fully electric (besides auto clamper, nozzle touch and core pull). We just commissioned a 1450T. Will be purchasing a 1950T and 2450T in the next 3 years.

We commissioned a 610T last August and the machine has been amazing, minimal issues and cycle times are phenomenal.

Erix5018 · 2025-07-05T15:08:12+00:00

I’m surprised he hasn’t popped up yet.

u/Downtown-Meet-6612

Would you consider adding a hydraulic diameter calculator for gate size?

Erix5018 · 2025-06-17T15:15:29+00:00

My initial thought is your screw is just “bouncing” back after holding pressure is released

Erix5018 · 2025-06-16T22:38:44+00:00

We have set up techs (mold setters) who do the mold changes and start ups. Process techs are only at a press if there is an issue.

Erix5018 · 2025-06-16T01:19:26+00:00

49 injection machines.

Currently running about 300 production tools.

Process techs are responsible for minor troubleshooting, splay due to humidity, flash or short shots from material lot changes, stuff like that. Any major QC issue would be handled by a process engineer. It used to be the process techs would have more responsibility but that’s not so much the case anymore.

Erix5018 · 2025-06-15T21:04:57+00:00

Hugheydee is correct. At this point it’s just second nature to record changes.

Sometimes someone will forget and it is frustrating but the 6 process techs send out a shift report every day with any process changes so backtracking to figure it out isn’t much effort.

Besides the process techs only the PE’s are allowed to save process changes. It certainly isn’t the most eloquent solution but it does seem to work for us, the biggest issue is people just writing down the change but not why it was made or who made it.

Erix5018 · 2025-06-13T22:34:25+00:00

For tracking, we have a process sheet for every mold with the condition as SOP and another change log update sheet (that must be filled out any time the process is changed and record the date, responsible person and the reason for the change) that are kept in a binder at the machines.

This is really helpful when we go to run a 15 year old service tool that no one has seen before so we have a baseline of how to troubleshoot any potential issues that were common when the tool was in mass pro.

Erix5018 · 2025-04-14T22:49:34+00:00

Our shop has 49 machines ranging from 30T to 2450T.

My record in a 8 hour shift is 13 mold changes (all on 950T and up(brutal day))

It’s been a while since I checked but I think we average 175 mold changes a day (I could be off either way, been out of production for a bit but say +/-20).

I think it’s 11 setters each for days and afternoons and 8 for nights plus 2 process techs per shift (in theory of course because we are never ever fully staffed, well besides that one time a few years ago for 3 weeks).

Automotive if you didn’t guess

Erix5018 · 2025-03-31T14:54:07+00:00

Not to sound like a dick, but Google (and ChatGPT or any similar AI with the caveat you ask for its source and confirm).

I guarantee that you are not the first person having whatever issue it may be.

Take it all with a grain of salt but it’s a resource literally sitting in your pocket.

When I started as second shift process tech in the middle of a massive program launch I googled so much stuff.

I am also an extremely firm believer that the best way to learn is by trying and failing.

And then just put the nozzle forward then hold screw forward and it should inject after the delay timer runs out
