📦 Request a Manufacturing Sample Kit

Want to evaluate our materials and manufacturing quality before starting your project? We can provide representative samples of commonly used materials with basic as-manufactured or standard finishes, subject to current availability.

Free standard samples are intended only for material inspection, functional evaluation, and basic manufacturing quality testing. They are not intended to represent customized cosmetic, decorative, or appearance finishes.

Samples requiring specific visual or cosmetic finishes—such as polishing, electropolishing, anodizing, electroplating, PVD coating, painting, dyeing, or other customized surface treatments—can be prepared separately. The related sample production and finishing costs must be paid by the customer.

To request a sample kit, please email us and provide your company name, required sample materials, intended testing purpose, and full shipping address.

Email: info@cai-precision.com

Standard samples of common materials with basic finishes are provided free of charge. Shipping is paid by the recipient and typically costs USD 20–50, depending on the destination.
