Serum Filling Machine?

I am looking for input on purchasing a semi auto serum filling machine. It appears the standard ones found on Amazon might not work with the viscosity of a face serum?

Any insights are appreciated. The serums we make are not that thick but def not wine or water thinness either.

hi wonder if theres any packaging engineers/manufacturers here that are willing to share insights into the process of getting a customer and prototyping their requests. I was curious about the tooling costs and what it actually costs the company to make samples of custom moulded pulp packaging.

Seeking Keyboard packaging advice

Hello all,

I'm trying to make a mockup of a keyboard packaging design. I wanted to know if anyone knew where to buy custom keyboard shaped boxes, ones that allow you to print your own design on them. I found a couple of websites, but I wasn't sure if they were credible. I'm going to attach two images of three different ideas i'm thinking about.

Looking for advice on how to create custom packaging

Hey!
So I’ve got a small side business where I make custom engraved tumblers, press hats and shirts, and other branded merch for the companies I do work for. I’ve got around ten businesses I work with regularly.

I’m thinking about offering custom packaging that matches each brand, basically templated packaging per product, with just the design swapped out for each client. It would be bundled into the product cost so it easy to order and I make a little bit more money.

I’ve got a Cricut and a laser engraver. Is this a good idea, and how should I go about this? I also am looking into windows inside the box, sleeves and other printed things, so if you know about this let me know, I don't want to buy the packaging it want to make it myself, at least until I know it works

Thanks!

Sample ordering for packaging.

I am dealing with a packaging company in China. They seems expert and direct manufacturers for paper tubes.

My question is that: they are asking $200 for samples which amount will be credited in my first order (sounds great) but if I dont like the sample or any issues related to the deal there will be no refund.

Any advice? because I can't make an order without samples and if I order samples from 3-4 companies it is gonna cost me over 1k

Can double-seam troubleshooting: why second-operation pressure can hide a first-operation defect

When a can double seam is out of spec, the instinct is often to tighten the second-operation roll. That can make the seam look flatter, but it usually cannot repair a first operation that failed to form the metal correctly.

The first operation creates the basic interlock between the can-body flange and end curl. It forms the body hook and cover hook and distributes the metal. The second operation compresses those already formed layers. If the first operation has poor hook formation, misalignment, the wrong tooling profile, or unstable lift, extra second-operation pressure can simply crush or thin the seam while hiding the real defect.

A practical troubleshooting order:

  1. Isolate affected cans and confirm the exact body and end specification.

  2. Inspect and measure the first operation before touching the second operation.

  3. Check seam width, thickness, countersink, body hook, cover hook, overlap, wrinkles or tightness, and compound condition.

  4. Verify chuck and roll profiles, lift height or pressure, centering, runout, bearing play, and tooling damage.

  5. Check for contamination and confirm that the can and end combination is compatible.

  6. Change one variable at a time, then cut and remeasure.

There is no universal seam dimension or machine setting for every can and end combination. Use the approved technical specification for that exact can-and-end combination and your plant's seam teardown procedure.

For people who maintain seamers: which first-operation defect do you encounter most often, and what check usually finds the root cause fastest?

Affiliation disclosure: I work with can-seaming equipment. I am sharing general maintenance experience; there are no commercial links in this post.

Packaging engineering cert

I have the opportunity to take the packaging engineering certificate at Indiana state. Professor thought I was a good fit due to my work experience. I already have a bachelors as well. Do you think this certificate (4-6 courses I think) will help me get my foot in the door?

Packhelp alternatives for custom packaging that don't lock you into big orders?

I've noticed most comparison articles focus on features instead of what actually matters to smaller businesses. For me it's really just sensible pricing, smaller orders, decent quality and easy reordering.What would you recommend?

3 weeks and post STILL not approved by mod

This is my second post about this issue.. its been 3 weeks now since I tried to make a post with some packaging automation that I made (including pics which is why it requires approval, I assume). I tried posting it again but it still says "waiting for mod approval." I sent a message to the mod (there is only one) via the "message the mods" icon on the sub info page, and also messaged them directly - no response in 3 weeks. Anyone have any idea whats going on? Is it normal for a sub to only have one mod and for them to ghost people like this?

Thanks all!
