Sample Card Manufacturing & Quality Control
Evaluate plating, enamel and metal construction before bulk production
Jin Sheu develops each Sample Card using the same manufacturing processes applied to custom metal gifts. Production may include mold development, zinc alloy die casting, trimming, polishing, plating, enamel coloring, epoxy coating, UV printing, assembly and quality inspection. Samples help buyers compare actual metal tones, textures and decorative effects instead of relying only on digital artwork. Our QC team checks plating consistency, color appearance, surface condition and construction so approved references can support later bulk production.
Custom Sample Card & OEM / ODM Workflow
From finish selection and artwork review to finished sourcing reference
A custom Sample Card project normally starts with your required product categories, artwork, plating options and decorative processes. Our workflow can include Concept / Artwork → Feasibility Review → Quotation → Artwork Approval → Mold Development → Sample → Finishing → QC → Packaging → Shipping. Sampling is approximately 7 days depending on design complexity and required finishes. Bulk production for related custom metal products is generally approximately 3–4 weeks, subject to product construction, quantity and project requirements.

Sample Card Plating, Enamel & Custom Finishes
Compare physical metal finishes instead of judging from screen colors alone
A zinc alloy Sample Card can combine multiple finishes on one presentation board. Common plating references include Gold, Silver, Nickel, Black Nickel, Bronze, Brass, Satin Gold, Satin Nickel, Antique Gold, Antique Silver, Antique Copper, Antique Zinc and Dual Plating. Decorative processes can include Soft Enamel, Imitation Hard Enamel, UV Printing, Laser Engraving and printed details. Clear epoxy may also be applied over colored areas to create a visibly glossy, slightly raised protective surface.

Flexible sourcing support for global OEM and ODM metal projects
Jin Sheu supports global sourcing through manufacturing resources in China and Vietnam. Depending on the Sample Card design, production process, quantity, target market and project schedule, manufacturing may be arranged through the most suitable facility. This China + Vietnam strategy may provide additional sourcing flexibility for buyers managing international supply chains. Our team supports factory-direct communication, sampling, production coordination, quality inspection, packaging and international shipment.
