How do brass jewelry factories price custom designs?

Tooling is usually a development charge associated with creating or modifying the mold, die, wax pattern, or related production aid. The unit cost covers repeatable costs for each finished piece, such as brass consumption, forming, labor, polishing, plating, inspection, and packaging. Buyers should request both figures separately and ask whether the quoted tool is single-use, reusable for later orders, or subject to revision charges. A design change after mold approval can require new tooling or partial rework, so the quotation should identify revision boundaries and ownership or retention terms for the tooling.

The largest plating-related variables are the visible finish, base preparation, number of process stages, plating material, color target, protective topcoat, and required thickness or performance specification. Brass often needs careful surface preparation because pits, scratches, porosity, and incomplete polishing can remain visible after plating. A buyer should provide reference colors, finish samples, wear expectations, and any restrictions for the destination market. Terms such as gold color or anti-tarnish should not stand alone; the quotation should state the finish system and inspection standard being priced.

Two visually similar designs can require different tooling because of dimensions, depth, undercuts, wall thickness, relief detail, attachment points, and the selected forming method. A larger or deeper piece may consume more material and need additional polishing access. Fine relief can increase mold preparation and finishing time even when the silhouette appears simple. Ask the manufacturer to confirm the production route, number of cavities when relevant, expected tool life, sample count, and whether the design is suitable for stable bulk production before comparing mold quotations.

Quantity changes the allocation of fixed development and setup costs across each piece. A small order may carry a higher unit price because tooling preparation, line setup, plating preparation, inspection, and packaging work are spread over fewer units. Larger quantities can support more efficient purchasing and production scheduling, but they do not automatically reduce every cost. Request tiered pricing at realistic quantities and verify whether the MOQ applies to the total order, each style, each color, or each plating specification. Also confirm allowable quantity variance and the price basis for repeat orders.

They are not automatically included. A quotation may cover one prototype, a mold sample, or a production sample while excluding courier fees, revised drawings, extra polishing, color adjustments, or additional sample rounds. Buyers should ask what approval stage the quoted sample represents and which changes trigger a new charge. A practical approval record includes the final dimensions, weight tolerance, finish reference, logo position, stone or component details, and acceptable visual deviations. Written approval reduces disputes when the sample and bulk production are evaluated against different references.

Testing and packaging should be priced according to the destination market, product claims, and sales channel rather than added as vague allowances. Confirm whether the project needs material or restricted-substance documentation, plating performance evaluation, nickel-related requirements, or other buyer-specific checks. Also specify the packaging format, insert, barcode, individual protection, carton configuration, and labeling responsibility. Ask whether testing is performed on raw material, finished jewelry, or a production lot, and whether laboratory fees, sample dispatch, and retesting are included. The final quotation should identify each assumption clearly.
