Haizol, a digital marketplace for custom parts manufacturing in Asia, concluded its 2025 Winter Supplier Discovery Tour, the company’s largest sourcing tour since the program began in 2019. The six-day program took place from November 22–27, 2025, across Shanghai, Suzhou, Hangzhou and Ningbo.

Largest International Delegation to Date

The tour brought together over 70 procurement managers, engineers and business owners from 27 countries, representing 15 industry sectors across four continents.
Each participant followed a structured track and completed seven factory visits aligned with their process and sourcing requirements.

Post-tour survey results reported:

• 92.8% of attendees were satisfied to very satisfied with the factory visits.
• 54% met 41-60 factories during the trip.
• 64.2% submitted RFQs or RFPs to suppliers they met on site.

These outcomes indicate strong sourcing intent and alignment between buyers and manufacturers.

Over 300 Factories Participated in Matchmaking Events

In-person matchmaking sessions were held in Suzhou on 24 November and Hangzhou on 26 November, with participation from more than 300 verified factories in custom parts production from Haizol’s network.

Supplier capabilities represented at the events included:

• CNC machining companies
• Injection molding and mold fabrication companies
• Fabrication and sheet metal companies
• Metal stamping and forming workshops
• Casting and die casting suppliers
• 3D printing and rapid prototyping companies

These sessions allowed attendees to meet multiple vetted manufacturers in a single location, compare capabilities, discuss technical drawings and assess suitability for upcoming projects.

Factory Visits Across Four Manufacturing Hubs

In addition to the matchmaking sessions, participants visited facilities in Shanghai, Suzhou, Hangzhou and Ningbo.
Across these sites, attendees observed:

• 3-axis, 4-axis and 5-axis CNC machining centers.
• CNC turning and mill-turn operations.
• Injection molding presses and mold-making workshops.
• Sheet metal production, laser cutting and welding stations.
• Stamping, forging and die-casting processes.
• Surface-treatment and finishing lines.
• Metrology equipment including CMMs, projectors and measurement instruments.
• Sample parts, tooling practices and production workflows.

Factories represented a range of capacities, with annual output values from 9 million RMB to over 180 million RMB, and included both export-ready and export-experienced suppliers.

Why This Tour Matters for Global Engineering Teams

The Haizol Supplier Discovery Tour is one of the few structured programs that provides direct access to verified custom-parts manufacturers in China.
The program was developed to address a common sourcing challenge: many CNC machining shops, injection molding workshops and related factories do not exhibit internationally and publish limited English-language capability information, making remote evaluation difficult.

Custom-manufactured components often require:

• review of machining or molding strategy.
• confirmation of tolerances and material compatibility.
• inspection of tooling and process control.
• verification of QC systems and certifications.
• physical assessment of production equipment and output.

These elements cannot be reliably validated through online profiles alone. The tour offers a practical method for companies to evaluate suppliers directly. Many attendees used the program to identify CNC machining shops, injection molding facilities, fabrication plants and other manufacturers suited to prototype, small-batch and mass-production needs.

Because of its structure, the Supplier Discovery Tour has become one of the available options for companies evaluating how to find reliable CNC machining suppliers, injection molding workshops or other custom-parts manufacturers in China. Participation is limited and available to members of Haizol’s free community network for custom parts manufacturing.
