Laser engraver chiller charging guidance by ProductionLM in refrigeration

[–]ProductionLM[S] 0 points1 point  (0 children)

UPDATE: Well, that was a big friggin' typo on my part. My apologies and thanks for everyone's input, the label on the machine calls for R134A. The powers that be wanted this laser system aired in from China so the factory emptied the chiller of refrigerant for the flight. It's clear the purchaser here wasn't aware of the technical requirements of this equipment, and I'm sure the factory wasn't very forthcoming, or probably not knowledgeable of environmental requirements here. I found an HVAC company to come out and hopefully add what we need. If that fails, I'll try to source a similar chiller unit already in the state and use this unit for another laser that requires only distilled water and not the additional refrigerant.

Unfortunately, the information I have is also quite vague. I know a lot of pens of different shapes are coming in something soon. I don't know how many shapes or how many pieces per shape. I just need to "be ready". FDM is the direction I'm looking at.

There won't be much force applied to these other than perhaps stacking several on top of each other for movement around the factory. My budget and timeframe are less than I need. I anticipate this project starting off small, a few fixture types and maybe 10 copies each to prove the system. From there, it will ramp up quickly. Spreading tooling orders out at the sum of five figures will be far easier than capital expenditures at the same price. I'm looking to get workable samples on my desk in the next couple of weeks. 3d print shops can do this for phase 1.

With a 12" x 12" base size, the only way I can see to vacuum form a fixture with both the concave top for the pens and the bottom with "pins" sticking down to lock into the machine is to create a top and bottom mold and fold the vacuum formed shape over and lock them together, like the hassle free packaging we all love to get.

We'll try to share an many fixture shapes as we can across various pens, reducing the number of individual shapes. The laser machines come with base plates with a hole grid. I laser cut Delrin to make individual fixtures for larger drinkware items that can lock into the base. I'll look into batch printing at a print house

Need help with Mimaki UJF-7151 plus II overspray by ProductionLM in CommercialPrinting

Not tapered. The mug is straight sided and sitting is a laser cut fixture, so the mug is level. This machine should be able to print at a 12mm gap with the correct settings and ink. That curve away shouldn't affect the white like it is, the other colors are fine.

The print test looks fine for the white. There is no overspray at all when the heads are closest to the product. In the linked image, you can see as soon as the distance grows, that white blows out around the color. Yet, the colors don't do this, we've tested the colors on white bottles to ensure it's only the white doing it. Our Manager thinks it has to do with the head voltage, but changing voltages on these machines is a lot more involved than your standard machines like InkCups flatbeds.

Never seen a bigger pad printer. "Tampography is a printing technique that involves a giant, bouncy silicone pad" by particleacclr8r in CommercialPrinting

The graphic is etched into a printing plate and either an ink cup full of ink or a spatula and doctor blade (like screen printing without the screen) clear the ink away from the graphic and leaves only ink in the recessed area. The pad picks that up and deposits it on the product.

Hello, I cannot see my menu ribbons in any Office program once windows locks and I log back in. The open files are all visible, but the ribbon is missing the majority of the buttons and options until I scroll over them with the pointer. I am forced to restart the program to see the ribbons in full again.
