Our scheduling gets judged on machine utilisation. High number good, low number bad, idle time gets questioned in the meeting.

Meanwhile the queues in front of those same machines keep growing and lead times keep slipping, and I'm fairly convinced the two are connected. Past a certain load every extra point of utilisation seems to buy a small amount of output and a lot of waiting.

Problem is "we should run the machine less" sounds like nonsense out loud. Nobody wants to hear that idle equipment is acceptable, least of all the person who signed for it.

So has anyone actually made this argument stick? What did you use — did you show it in lead time numbers, did you quietly stop scheduling to 100% and let the results speak, or did you give up and live with it?

Or am I wrong about this and the utilisation target is fine and my real problem is somewhere else.

Hi guys,

We’re gathering a bunch of data for our product by manual input, but often get request to automate this as well. We’ve mainly got experience connecting edge data using Azure IoT hub with an edge device by advantech (uno series). I’m now looking into suppliers that provide a more seamless experience, but most of them require hefty licenses on top of the hardware. Mostly looking for opc ua / modbus retrieval but extendable to other data sources in the future. What are you guys using for data capturing? We want to limit the amount of vendor lock-in for both ourselves and our customers.

"You are required to establish CCM data exchange via Catena-X with us. Yours truly, OEM."

— What the hell is that? 😳

"Oh, no problem. Here are the guidelines:

1. Create your BPNL
2. Understand digital twin logic
3. Set up an Eclipse Dataspace Connector

4. More technical stuff that's hard to understand ...

5. Start exchanging CCM (company certificates) with us."

🥵

So... what do you do?

Do you try to figure it out yourself?

Do you hire someone?

And if you hire someone — who?

I've spent quite a lot of time recently getting our company (actually, multiple legal entities) through the Catena-X ecosystem, and I was surprised by how much there is to figure out before you can actually exchange data with an OEM.

Things like:

• Cofinity-X / onboarding
• BPNL / BPNS / BPNA
• managing participant vs. managed partner
• EDC / connectivity
• choosing the right app providers
• Catena-X use cases
• PCF / certificates / Battery Passport
• figuring out which provider actually makes sense for a specific requirement
• coordinating everything between the supplier, provider and OEM

And the interesting part is that you don't necessarily need to build everything yourself. It doesn't have to be an IT development project.

There are app providers for most of the technical pieces.

The difficult part, especially for a company approaching Catena-X for the first time, seems to be understanding:

What do we actually need? Who provides it? How much will it cost? And how do all the pieces fit together?

For me, that was the biggest challenge.

I needed quite a few meetings with people who actually work in the Catena-X ecosystem, and I had to read A LOT of documentation before I even started to remotely understand the concept and logic behind the system.

Then came the next challenges:

How do you manage multiple legal entities under one account?

How do you connect them?

How do you handle different sites / factories?

And then... the app provider presentations. 😅

One thing I learned is that Catena-X (or Cofinity-X) is basically just the "platform".

Think of it like an iPhone.

The app providers are the apps that enable you to actually perform specific functions and exchange specific data with your customers.

Sounds simple.

Until you start talking to providers.

Almost everyone supports everything, every use case "we got you covered!" — until you start digging into the details.

"Yes, we support this use case, but we'll need your IT department to develop a custom API on your side."

And suddenly your supposedly simple Catena-X project becomes an IT development project.

It's a bit like buying a car and then discovering that you need to install the steering wheel, tires and indicators yourself.

Anyway, maybe this is less of a question and more of a personal rant. 😅

I'm just happy that after all this time, I managed to get our company successfully onboarded to Catena-X and start an actual data exchange with our OEM.

So I'm curious:

Has anyone else had a similar experience?

How did your Catena-X project go?

What was the biggest challenge?

And if you're a smaller supplier — did you do it internally, or did you bring in an external consultant / service provider?

PS: If anyone has questions about the practical onboarding experience, feel free to ask. I'm happy to share what I've learned.

Need advise

I am an independent manufacturing consultant with 30+ YoE. I advise companies on all aspects related to manufacturing, production, quality and efficiency. I also
hold a black belt in six sigma.

I have leveraged my network and other expert network platforms for independent consulting in the last few years. I have now reached a point where I am unable to figure out further growth. Clients have exhausted and i am unable to see any way further.

Pls advise / suggest on how do I grab more projects. Would appreciate any leads/ firms looking for independent consultants.

I’m in my family’s tractor spare-parts business in India, mainly dealing with gears and transmission parts.
Honestly, I find the traditional aftermarket distribution model pretty fucking boring and slow-growing. From what I understand, it can take 10–15 years to build something substantial.
OEM manufacturing seems much more attractive, but there’s a catch.
If you’re a relatively new manufacturer, no OEM is going to commit a big order and tell you to invest first. And if you wait for an OEM commitment before investing, you could potentially spend 1–1.5 years just waiting for orders/development/approval.
There are also already a lot of established manufacturers competing for these OEM contracts.
So I want to hear from people who have experience in manufacturing/OEM supply:
Is taking a calculated loan and investing upfront to build OEM-level manufacturing capability a reasonable strategy, or is it too risky without guaranteed orders?
And realistically, how difficult is it for a new manufacturer to break into tractor/automotive OEM supply when there are already so many established suppliers?

Ive emailed and reached out to so many manufacturers to make flip flops like these with various soles and strap colors but it seems like no one will get back to me. Does anyone manufacture sandals like these or can get me in touch with someone they know who does?

I’m developing a small handbag brand and I’m trying to find the right manufacturer for premium-looking non-leather handbags, mainly structured bags, shoulder bags, top-handle bags, etc.
I’m specifically looking for PU/faux leather, not genuine leather.
My initial requirement would be relatively small, roughly 50–100 pieces per style, potentially starting with just a few styles and scaling successful designs later.
I’ve already tried sourcing in Dharavi, Mumbai, speaking with several karigars/vendors. Unfortunately, the samples I’ve received so far have looked like inexpensive wholesale-market products rather than the quality level I’m targeting. The construction, material feel, structure and finishing weren’t good enough.
So I’m wondering whether I’m simply looking in the wrong part of the manufacturing ecosystem.
I’m currently considering:
Delhi/NCR, India
Mumbai/other parts of India
Guangzhou/Guangdong, China
potentially Vietnam or other manufacturing hubs
I’m not looking for the cheapest manufacturer. Quality and the ability to develop a good sample are much more important initially.
The kind of quality I’m aiming for is closer to a premium contemporary fashion brand rather than a generic PU/wholesale handbag.
For people who have actually manufactured handbags:
Where would you look for this type of manufacturer?
Is India capable of producing genuinely premium PU/faux-leather handbags at 50–100 pcs/style, or is China significantly better for this?
Are there particular manufacturing regions/clusters I should investigate?
What should I look for when evaluating a factory’s sample quality?
How do you distinguish a real manufacturer with an in-house sample/pattern-making capability from a trading company or small workshop?
Are there specific things I should specify for PU/faux leather, lining, reinforcement, edge finishing and hardware?
If you’ve personally worked with a manufacturer you would recommend, I’d especially appreciate hearing about your experience.
I’m happy to pay properly for good sampling, I’m not trying to squeeze the factory on price. The priority is finding someone who can actually execute a premium product at small initial volumes.
I’d especially appreciate responses from people who have personally manufactured or developed handbags, rather than generic supplier recommendations.

I have an interview at a gypsum board factory this week. I have 6 years factory experience but its in a papermill that was union the gypsum plant is not union.

I'm wondering how much more physical is gypsum factory work? Its on the same Dupont schedule I had before. This factory recently had a bunch of upgrades so I'm assuming a good bit will be automated or semi automated.

Please enlighten me on how terrible or manageable a gypsum factory job is.

Please let me know if this isn’t the right subreddit for this.

Where I live, it is very common for Peugeot 206 sunroof glass panels to be stolen. Thieves can apparently just pry them up with a tool and remove the panel in well under 15s. [video]

People often install simple anti-theft bars that prevent the sunroof from opening, but I'd like to design something that keeps the original functionality. [picture]

Since my own sunroof was stolen, I've been thinking about designing and manufacturing a system myself. The basic requirements are:

• The sunroof must remain fully functional.
• The system should be visible from outside, so a thief can immediately see that the glass is secured.
• It should provide real mechanical resistance, rather than being something that can simply be bent or removed quickly with a pry bar.
• Ideally, the glass itself shouldn't be the structural element resisting the attack. I'm thinking more along the lines of a "cage" or retaining structure around the glass. Even if someone manages to release the glass from its original mounting, it should remain trapped and attached to the vehicle.
• Preferably, the system could be released from inside the car. It doesn't necessarily need to be lockable/engageable from inside; being able to release it from inside would already be useful.
• The system shouldn't interfere with the glass when the sunroof opens.

The difficult part is the last one.

The 206 sunroof glass first has to move upward a few millimeters and then slide rearward [video]. So there isn't simply a single direction of movement that I can leave clear.

My initial idea was something like two transverse straps crossing over the roof with a small clearance above the glass. These would be connected to another perpendicular retaining piece, somewhat like a hook, which would catch the glass from behind [something like this but making shorter the back one]. The retaining piece would somehow pivot or lift out of the way when the sunroof needs to open. [some skteches of my ideas]

The problem is that I haven't found a mechanism that seems mechanically sound: it needs to leave enough clearance for the glass to rise and slide back, but at the same time it shouldn't be possible for someone outside the car to simply force the mechanism upward or sideways

I've also seen a solution where a metal bar is mechanically attached directly to the glass, with an internal locking mechanism that prevents it from being removed.

I don't really like this approach because it still makes the glass itself part of the load-bearing security system. [some pictures] In many attempted thefts, the glass ends up shattering when someone applies enough force to pry it out.

I'm particularly interested in suggestions for mechanisms that could accomplish this and that could realistically be fabricated from steel or aluminum.

I can provide what would help.

What kind of mechanism would you use for this?

What safety lesson did you have to learn the hard way? Whether you accidentally forget something or are not completely aware of your surroundings. We’ve all been there. I would like to hear yours and hopefully learn from you instead of having to learn the hard way (again) lol.

I am currently working on restoring an old toygun and that thing needs 30 of these flatsprings to function.
The problem is, that all my local shops charge me ~400€ for a set of those, which is a bit much given the purpose they serve.

Width is 3mm, thickness is 0.4mm and the material is probably 1.41 steel.
The big circle at the bottom, which a lot of companies cant do.

Are there any other "JLC-like" companies that I could contact?

We're a mid-size pharma facility sourcing a high-accuracy tablet and capsule counting machine that must feed both our bottling line and blister packaging line. We're evaluating Chinese OEMs and would appreciate input from anyone running similar equipment.

From our research, counting technology is the key differentiator. Photoelectric or infrared multi-lane counters with dust-proof sensors claim accuracy above 99.9%, while mechanical mold counters stay reliable even in dusty environments. We need a machine that handles tablets, hard and soft capsules, and odd-shaped or coated products without jams.

For bottling, we'd want it integrated with a bottle unscrambler, desiccant inserter, capping, induction sealing, and labeling—plus a checkweigher to catch underfills. For blister lines, we need it to link cleanly to the forming and sealing stage.

What specs should we insist on? We're thinking GMP/CE compliance, tool-free changeover across product sizes, 99.9%+ accuracy, and minimal downtime. Does anyone run a counter feeding both bottling and blister lines reliably? What pitfalls or supplier red flags should we watch for?

Seems like it would be a cheap way of enhancing the mechanical properties of cast wheels etc.

Hi everyone! I am currently in the process of launching my own designs to sell in my boutique. I have talked to a couple of manufacturers and have ordered samples. 3/4 have already sent samples to me but the other manufacturer, we are still talking about sourcing fabrics. Timeline wise, 3 manufacturers were able to send me samples in the span of a month and half, 4th manufacturer, I contacted them last August 1st, so basically it’s been a month of us talking back and forth about designs and fabrics. This is my first time working with a manufacturer so I am not sure what is a normal timeline for the initial phase, samples.

I have also decided that I like one of the 3 manufacturers work and I’m currently asking them to send me another sample, to make sure their quality is consistent. So you can see that we’re moving along. My goal launch date for my own designs is mid November.

Is it time to part ways with 4th manufacturer and ask for a refund? Or is it normal for fabric sourcing to take awhile? They haven’t sent me any fabric options yet, so it really isn’t me who’s taking too long to respond nor choose between options.

I'm trying to switch into SAP Manufacturing (DM, PP, MM) after 5+ years working with SCADA systems in manufacturing environments. My background is heavily focused on industrial automation, production systems, integrations, and shop-floor operations, so I feel like I already understand a lot of the business and manufacturing processes that SAP is supposed to support.

The problem is that every application gets rejected almost immediately because I don't have direct SAP experience (well, I do but it's in SAP HCM).

What I'm struggling with is the classic catch:

- Companies want SAP experience

- I can't get SAP experience because nobody will hire someone without SAP experience.

- I can't even find many ways to get meaningful hands-on practice with DM/PP/MM outside of a real project.

For those of you who made a similar transition (especially from OT, MES, SCADA, automation, or manufacturing IT), how did you break into SAP?

I'd appreciate any advice from people who've actually made the jump.

Can you tell me how something like this is manufactured ? Like the technical details

I was put on a fluidized bed dryer development project without prior experience and I have no clue what to start with... Is there any good resources i can rely on to get some basic idea and what to look for?

I own a factory in Pakistan with a 125-ton cold chamber aluminum die casting machine Toyo Machinery & Metals Co., Ltd. (Model BD-125V4-N, made in Japan, 2002) plus workers with years of hands-on experience running this type of equipment. Photos of the setup and a sample cast part attached.

We're currently manufacturing aluminum engine components for a Pakistani automotive client, so the shop is actively running production for a real OEM relationship, not just idle capacity looking for its first customer.

The local market here isn't in great shape though, so instead of depending on local demand, I want to build this into an export-focused B2B contract manufacturing business.

My own background is software engineering + sales, so I can handle international lead generation, websites, outreach, research, and client acquisition myself. What I'm missing is the industry knowledge: which products/markets actually make sense for a machine this size, and how sourcing actually works in this industry from the buyer's side.

What I'm trying to figure out:

• What types of high-volume aluminum components can be handled by a 125T cold chamber HPDC machine?
• Which global industries should I be targeting? automotive, electrical, industrial, lighting, electronics, hardware, etc.?
• How do small die casting manufacturers typically land international OEM/contract manufacturing clients?
• Is it smarter to approach OEMs directly, or go through suppliers/distributors/sourcing agents?
• What capabilities should I invest in first? CNC finishing, plating, in-house inspection/QC, etc. to be taken seriously as an export supplier?

I'm not looking for a DIY product idea to sell myself, I want to find components companies already manufacture and buy in volume, and compete as a contract supplier for that existing demand out of Pakistan.

If you've worked in die casting, sourcing, or manufacturing, how would you approach this in my position? Where would you look first, what would you avoid, and how do people actually validate a market before chasing it?

We are sourcing for a product, small volumes, and ive been hitting some roadblocks. Also just for context im 20 and currently in my undergrad program at tetr college.

First quote is reasonable. Then there's a call, they work out roughly who they're dealing with, and the second quote is different. Higher unit price, higher MOQ, longer lead time.

I think it's a rational read on how likely I am to reorder.

What I want to know is what actually changes that read. Do you overstate projected volume? Do you pay for a sample order at a bad price to establish history? Do you just find suppliers small enough that you're a normal customer?

We recently ran into a persistent bottleneck on a job requiring 1mm cross-drilled safety wire holes through 10mm of tough alloy bolt heads. The main headache was that the holes start directly on a 45-degree angled chamfer. Standard micro-drills were walking instantly on entry, and EDM was taking close to 10 minutes per bolt while leaving recast layers on the internal walls that wouldn't pass fatigue specs. Instead of tying up a large VMC or relying on manual bench jigs, we configured a compact 400x300x120mm precision drill center equipped with a dual-spindle head layout.

The setup handles the operation in a continuous cycle without standard ATC delay. Spindle one carries a small end mill running a fast plunge macro to face off a microscopic 1.2mm flat landing pad directly onto the inclined chamfer. Spindle two is a high-speed 60,000 RPM electric spindle carrying the 1mm solid carbide drill. By spotting the flat first, we eliminate the uneven side-thrust vector that normally snaps micro-drills on sloped entry. Running at 60k RPM lets us maintain proper surface footage for the micro carbide, feeding through the full 10:1 depth-to-diameter ratio with a controlled pecking routine. Aggressive, targeted fluid delivery at the tool nose is critical here; it flushes micro-chips out of the 10mm deep cavity so swarf doesn't pack the flutes and wedge the tool.

To be honest about machine limits, this compact drill-tap cell is strictly a high-speed micro-hole and light milling rig. With 120mm of Z-stroke and light ER-collet spindle mechanics mounted on precision linear guides and ground ball screws, you obviously aren't going to face mill steel plates or take heavy side loads. The physical architecture is tuned for low moving mass, minimal thermal drift, and holding ±0.02mm true positioning under high RPMs, not high mechanical stiffness for heavy metal removal. If you try to hog material on a setup like this, you will chatter immediately.

That said, taking micro-drilling off our primary vertical mills dropped our cycle times from roughly 8 minutes down to 3 minutes per part, while drill life went from breaking every dozen holes to running entire shifts cleanly. Happy to talk dual-spindle coordinate offsets, pecking depth steps, or chip flushing setups if anyone is wrestling with micro-holes on angled surfaces.
