China Manufacturing Decoded

What should you do when production is already underway, but quality problems keep appearing from one shipment to the next?

In episode 336, Adrian and Renaud answer a listener question from David B. and explain how buyers should investigate recurring production problems before deciding whether to fix the situation or transfer manufacturing elsewhere.

They begin by separating product design problems from manufacturing and workmanship issues. A product that cannot withstand normal use may be fundamentally under-designed, while products arriving dead on arrival are more likely to indicate manufacturing failures.

The discussion also covers reliability testing, pilot production, supplier audits, corrective action plans, containment measures, documented process changes, fixtures and mistake-proofing.

Renaud explains why inspections can provide useful short-term protection but should not become a permanent substitute for a functioning supplier quality system. If repeated mistakes continue, records are unavailable, or production is being moved between facilities without your knowledge, it may be time to walk away.

You will learn:

• How to distinguish design failures from manufacturing problems
• When early production issues may be understandable
• The warning signs that a supplier has no effective systems
• What evidence to request after a supplier claims a problem is fixed
• Why corrective action and inspection must be used together
• When transferring production becomes the safest option

Your electronics work. The firmware runs correctly. The mechanical components fit, and every subsystem has passed its individual tests.

Then everything is installed inside the final enclosure, and entirely new problems begin to appear.

In episode 335 of China Manufacturing Decoded, Adrian is joined again by Paul Adams from the group's contract manufacturer, Agilian Technology, to explore one of the most difficult stages of hardware development: product integration.

Are trade shows still worth attending when buyers can search for suppliers through Alibaba, Google, ChatGPT, and other online platforms?

For physical products, Renaud Anjoran believes they still offer considerable value, provided buyers arrive with a clear objective and understand how to assess the companies they meet.

In this listener Q&A episode, Adrian and Renaud answer Robert C’s question about events such as the Canton Fair, Global Sources, CES, and IFA.

Adrian revisits a classic episode (originally Ep. 30, Nov 2020) in this monthly rewind, Episode 333 of China Manufacturing Decoded, and sits down with Sofeast CEO, Renaud, to unpack the three types of quality-control (QC) plans every importer and manufacturer should agree before production starts.

Renaud explains three types of QC plans:

The product quality control plan, often linked to the manufacturing contract.

The process control plan, which controls quality during production rather than waiting until the end.

The QC plan for new products, which helps buyers and suppliers think through risks before mass production starts.

Key takeaways for listeners: QC planning is a pre-production activity not a rescue job; define a clear product quality standard; decide how quality will be controlled during production; and for any new product, agree on what must be proven before mass production. If any of those points are unclear, that’s likely where your next quality risk is hiding.

Setting up a new factory is a major strategic decision. It is not just about finding cheaper land, moving away from China, or following other companies into Vietnam, Mexico, or another popular manufacturing location.

In this episode, Renaud speaks with David Collins, CEO of Manufacturing Transformation Group, about what companies need to think through before relocating production or building their own factory.

They discuss why more companies are considering factory relocation or ownership again, especially after COVID, tariff changes, supplier dependency, and IP concerns. But David explains why the first question should not be “where should we move?” It should be “what are we actually trying to accomplish?”

The conversation covers the real trade-offs between China, Vietnam, Mexico, and other locations; why labour cost should not be the only driver; how supplier location, workforce skills, logistics, and infrastructure affect the decision; and why companies need a proper BOM, cost model, and feasibility study before making a move.

They also get into greenfield vs brownfield factory projects, equipment selection, factory layout, commissioning, factory acceptance testing, and why automation can be a waste of money if it does not fit the real production process.

The key message: moving to a new factory is a rare chance to redesign your manufacturing system properly. But if you simply copy the same poor layout, weak supply chain, bad inventory habits, and unsuitable equipment into a new building, you may just move the mess.
