Custom medical parts and components from verified Chinese factories. CNC machining, injection molding, rapid prototyping, and fabrication in one platform.

What Haizol covers for medical applications:

1. CNC Machining - 3/4/5-axis, stainless steel, titanium, plastics. Tolerances to ±0.025 mm.
2. Injection Molding - PEEK, ABS, PC, PEI, and medical-grade plastics for housings and enclosures.
3. Rapid Prototyping - CNC, 3D-printed, and hybrid parts for testing and validation.
4. Sheet metal, die casting, and precision assembly for enclosures and structural components.

ISO 13485 certified factories. NDA before any CAD file is shared.

Last week, companies from 31 countries joined our 2026 Supplier Discovery Tour and flew to China to see factories for themselves ✈️.

They walked factory floors, met production teams face to face, participated in matchmaking sessions, and built the factory relationships that strong supply chains in China are made of. ⚙️

A huge thank you to everyone who joined us. Safe travels, and we hope to see you in our next edition.

ISO 2768-mK is on more engineering drawings than any other general tolerance callout. 📐

Choosing the wrong class - tighter than needed inflates machining time, looser causes assembly failures.

📌 Part 1 (ISO 2768-1): 4 dimensional classes - f (fine), m (medium), c (coarse), v (very coarse).
📌 Part 2 (ISO 2768-2): 3 geometrical classes - H (high precision), K (standard), L (low precision).
📌 Most CNC machining and sheet metal drawings default to ISO 2768-mK.
📌 A 50mm dimension under class m: ±0.3mm deviation. Under class f: ±0.15mm.

If you're sourcing CNC parts from China, the tolerance class in the drawing title block directly affects your quote price and conformance rate.

📊 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.
