📊 The right injection moulding resin is selected in this order: regulatory, thermal, mechanical, cost. Most teams reverse it and over-spec by 20-100x on materials.

PEEK and PEI typically run 20-100x commodity pricing. PPS runs 5-15x. The factory pool that can process them is much narrower - and the wrong resin call locks you into a small supplier base for no functional reason.

➡️ Regulatory: FDA, ISO 10993, food contact, flame retardancy
➡️ Thermal: peak operating temp and continuous-use limits
➡️ Mechanical: load, impact, fatigue, stiffness
➡️ Cost: only after the first three filters narrow the field

"Die casting vs injection molding" is one question, not ten.

80% of real-world part decisions come down to a single test: does your part need to be metal?

➡️ If yes, die casting wins. Aluminium, zinc, or magnesium give you heat transfer, EMI shielding, and stability under load that no plastic matches.

➡️ If plastic works, injection molding wins. Wider material range, lower density, and tolerances down to ±0.025 mm. Glass-filled nylon closes most of the strength gap.

The other 20% - tooling budget, volume, lead time - is secondary. Both processes break even at 5,000+ units, and China tooling runs 30-70% less than comparable Western suppliers.

📊 "China CNC only works for mass production." 63.3% of orders in our 2026 dataset are for 50 units or fewer.

The median MOQ across the verified factory base is 10 units. One-off prototype sourcing from China is normal - the question is which shops to trust.

Four data points from the same dataset that change how procurement teams approach it:

➡️ 82.2% of China's CNC capacity sits in three provinces (Jiangsu, Guangdong, Zhejiang)
➡️ 38.8% of verified factories run 5-axis equipment
➡️ 48.2% offer Swiss machining to ±0.005mm
➡️ Median quote response from a verified factory: under 1 hour

📊 Sheet metal sourcing breaks at the bend, not the cut.

Laser cutting at ±0.05 mm is widely available across China's verified factory base. The hard part is matching that with the right press brake, weld, and finish under one quote - so the part arrives complete instead of half-fabricated.

➡️ Laser cutting to ±0.05 mm tolerance
➡️ Press brake bending and forming
➡️ TIG and MIG welding, structural assembly
➡️ Materials: 304, 316, 430 stainless, 5052/6061 aluminium

That is what verified factory routing solves: one RFQ, multiple capability-matched quotes, all four steps covered.

Here is the fastest way to choose between metal stamping and die casting for any part.

Do not die cast the whole part when you only need to die cast part of it.

📊 Medical device sourcing in China comes down to three things in one quote: titanium or PEEK to ±0.025mm, ISO 13485 documentation in the file, and a factory that has shipped to medical OEMs before.

The factory pool that can do all three is small.

➡️ Verified medical-grade CNC and molding network
➡️ Materials covered: titanium, PEEK, PEI, ABS, PC, stainless steel
➡️ Tolerances as tight as ±0.025 mm (±0.001 in)
➡️ ISO 13485 and ISO 9001 documented before quoting

For procurement teams at medical device OEMs, that means quotes you can take to your QA team without rework.

🎥 Missed our Supplier Discovery Tour webinar? The recording is live.

Tom, a UK buyer in recycling equipment, joined our November 2025 tour and sat down with us afterwards to share what the trip was actually like. His clip is in the webinar.

He's joined by two other buyers who walked factory floors with us:
- Marta (North Macedonia) - industrial equipment
- Amir (Saudi Arabia) - 15-year China sourcing veteran

Together they cover:
🏭 What surprised them on the factory floor
💬 Questions they wish they'd asked before going
🤝 What the experience actually looked like day to day

92.8% of buyers who joined our November 2025 tour said it was worth it. This webinar is three of them explaining why, in their own words.
