Frequently Asked Questions

OEM (Original Equipment Manufacturing) usually means the buyer provides the design or specification and the manufacturer produces to the agreed brief. Set product requirements, branding, inspection criteria and ownership terms in the project agreement.

ODM (Original Design Manufacturing) usually means a supplier offers an existing platform or develops a product to the buyer brief. Confirm customization limits, design and tooling ownership, brand rights and any exclusivity in writing.

DAYIN publishes an OEM/ODM scope that includes product development, mold design and fabrication, plastic injection molding, finishing and assembly. Confirm the work split, production site, available capacity, samples, MOQ and schedule for your product in a project-specific quotation.

MOQ and pricing vary by model, material, tooling, customization, packaging and forecast volume. Send the selected product or drawing, target market and quantity for a project-specific quote.

There is no single lead time for every OEM/ODM project. Timing depends on design readiness, tooling, material availability, sample approvals, order quantity, and production scope. Request a written schedule that identifies the start point, sample and approval milestones, production window, and shipping assumptions.

Use the DAYIN contact page and include your product type, drawings or specifications, target market, forecast volume and required services. Ask for a written project review covering MOQ, samples, schedule and destination-market documents.
