Custom development capability

Beyond standard products: co-development around your application

The standard portfolio is a starting point. When an existing product does not fully match the workpiece, equipment, or target finish, GUOWIN can review and advance a custom development path with the customer.

Define the real process

Confirm the workpiece, geometry, current defect, existing method, target finish, and production volume.

Build a candidate package

Start with standard products and combine abrasive formats, contact materials, and polishing tools.

Co-develop where needed

Review project-specific needs for construction, dimensions, format, conversion, or a dedicated product combination.

Validate samples and process

Compare finish, service life, cleaning, cycle, and repeatability on representative parts before production release.

Start with the application

Share the workpiece, current process, and target result to discuss a standard package or custom development
