Haizol, a digital platform for sourcing custom parts manufacturing online, announced the completion of its 2025 Winter Supplier Discovery Tour, held November 22–27, 2025 across Shanghai, Suzhou, Hangzhou and Ningbo. Haizol’s platform is widely used by companies sourcing CNC machining, injection molding, casting, sheet metal, stamping and other custom parts online.
 

Program Summary

The six-day program, held from November 22–27, 2025, brought business owners, international procurement and engineering teams into verified manufacturing facilities representing machining, molding, casting, sheet metal, stamping, fabrication and rapid-prototyping processes.

More than 70 participants from 27 countries attended the tour. Each participant followed a structured schedule and completed seven factory visits matched to their technical requirements.

Survey findings included:

• 92.8% of attendees were satisfied or very satisfied with the factory visits.
• 54% met 41–60 suppliers during the week.
• 64.2% submitted RFQs or RFPs to suppliers they met onsite.

Supplier Matchmaking Events

During the 2025 Winter Supplier Discovery Tour, Haizol hosted large matchmaking sessions in Suzhou and Hangzhou, bringing together more than 300 verified factories in custom parts manufacturing from its manufacturing network.

Capabilities represented included:

• CNC machining
• Injection molding and mold fabrication
• Sheet metal fabrication
• Metal stamping and forming
• Casting and die-casting
• 3D printing and rapid prototyping

Factory Visits Across Four Custom Parts Manufacturing Hubs

Delegates conducted factory visits across Shanghai, Suzhou, Hangzhou and Ningbo. Visits included reviews of:

• Multi-axis machining centers.
• CNC turning and mill-turn operations.
• Injection presses and mold-making workshops.
• Sheet metal cutting, bending and welding lines.
• Stamping and die-casting operations.
• Surface finishing processes.

Participating factories reported annual output values ranging from 9 million RMB to more than 180 million RMB.
 

Why the Program Was Created for Custom Parts Sourcing

The Supplier Discovery Tour was established to address sourcing challenges that online information alone cannot resolve.

These reasons include:

• Many capable factories do not attend international or large domestic trade shows.
• Online profiles and photos cannot show the true picture of the factory's skillset, tolerance control or QC systems.
• Overseas teams struggle to navigate China’s manufacturing landscape independently.

Companies typically begin supplier evaluation on Haizol’s online platform, then use the tour as a structured method to confirm manufacturing capability, discuss drawings with engineers and identify suitable factories in person.
 

A Hybrid Sourcing Channel

This online-to-offline model has become a commonly used sourcing channel for teams assessing CNC machining, injection molding, casting, sheet metal fabrication, stamping and multi-process assemblies in Asia.

As companies move more supplier research online, there is still a clear need for direct factory evaluation in custom-parts manufacturing. The tour offers a consistent way for global teams to verify manufacturers beyond what digital profiles can show.
