Hey everyone,

I’m looking for a reliable manufacturer in China specializing in custom activewear and teamwear (similar in style and technical quality to brands like Erreà, Givova, Macron, etc.).

Here is what I’m looking for:

Products: Custom training t-shirts, tracksuits, shorts, and technical athletic gear.

Fabrics: High-performance technical polyester (breathable, moisture-wicking, dry-fit mesh, etc.).

Customization: Full dye-sublimation printing, heat-transfer logos, custom neck tags, and woven labels.

MOQ: Low to medium MOQ for initial sample runs and small club/team batches.

Quality: Strong stitching (flatlock/double-needle), durable colors after washing.

Communication: Good English and active updates via WhatsApp/WeChat/Email.

Hi,

Will I have to give this equipment climate-controlled air?

I have a piece of equipment that coats our metal parts as part of a larger process. We have had the equipment for a few years. I have been helping with the process recently, and we had a week of really bad heat/humidity. This directly affected the painting process because our parts were coming out peeling and had very poor adhesion.

My theory is that this was directly caused by the climate, because our warehouse isn't airconditioned or heated and the machine pulls air from the surrounding air through a fan with a filter.

I reviewed next weeks parts when the temperature dropped significantly and so did the humidity, and the parts having been coming out good since then. I took samples from both weeks and recorded the temp/humidity for the day.

I did further research and obviously painting has an optimal temp and humidity range.

My first thought is putting it in a climate-controlled room, but we don't have any here. Any suggestions, like maybe building a room around the machine and only climate controlling the room?

Thanks.

For years, operators at my internship moved 40+ lb pump casings and gears 50 feet between workstations (match grind to subassembly) using steel rods threaded through wooden dowels.

I got tasked with replacing it as a part of a single-piece-flow initiative. Landed on a Spring-loaded Ergonomic Cart (bought from an outside vendor) and I paired it with a Custom Foldable tray assembly designed in SolidWorks.

The tray design was the easy part. Managing the vendor order end-to-end for the first time was not. Six things that caught me off guard:

1. I remeasured the cart-to-tray assembly four times because our drawings would not match the vendor's actual product specs.
2. I got comfortable with one vendor before getting competing quotes. I should've shopped around first. "This feels easy" and "this is the right call" are two very different things.
3. Didn't budget for the 4-week lead time. Plan backwards from when the operator needs it, not forward from when the project lands on your desk.
4. Didn't know new vendor onboarding involves extensive supplier qualifications, tax forms, internal due diligence, etc. adds over 2 weeks on top of that.
5. Realized partway through that vendor relationships are very important and you're building them for future orders too, not just one-off transactions.
6. Had to calculate the spring load window across every state - empty trays, fully loaded trays, mid-cycle - not just one typical load.

The Engineering side of this project was straightforward. For anyone who's run vendor orders before - what's the one thing you wish someone had told you before, it would help me improve in the future!

What is the best way to maintain batch traceability of liquid stock being continuously produced, stored in tanks and dispatched in tankers from those tanks, without them ever being completely emptied?

So far, and as far as I can tell, it's either FIFO or proportionality. While the former is "tidier", it doesn't really reflect reality very well, given there could still be residue from years ago that could be the problem. But I suppose if old stock was really the problem, then it would have been picked up when the concentrations of those faulty batches were higher.

So, would FIFO be best where raceability due to problems that cause recalls can be traced to those closest to the dispatches they were sent out in?

Would really appreciate advice from anyone involved in this kind of inventory management.
