Application at a glance ### Typical component families | Perfume cap blanks | Brass, turned + pre-polished | Bottle-neck rings | Brass, aluminum, Swiss-turned | Pump mechanism parts | 316, brass, Swiss-turned ### Typical supply parameters | Batch range | 5,000–50,000 pcs per family | Surface | Pre-polish to Ra ≤ 0.2 before plating | Documentation | EN 10204 3.1, NDA on request ## Parameter Quick Reference | Parameter | Specification | Component families | bouchons de parfum, bruts (perfume cap blanks); bagues de cols de flacons (bottle-neck rings); lests (counterweights); mécanismes de pompes (pump mechanism parts) | Typical materials | brass; brass, aluminum; brass, steel; 316, brass | Machining processes | turning + pre-polishing to Ra ≤ 0.2; Swiss-type turning; turning / cold forging | Typical batch sizes | 5,000–50,000 pcs per family | Default tolerance scheme | Pre-polish to Ra ≤ 0.2 before plating | Material certificates | EN 10204 3.1, NDA on request | Inspection requirement | first article inspection | Quotation and sample lead time | quotation within 48 hours; first samples in 7–15 days ## Industry scenario: metal blanks as the Tier2 position The luxury and cosmetics packaging industry concentrates glassmaking and decoration regionally, and the metal components — perfume cap blanks, bottle-neck rings, counterweights and pump mechanism parts — are sourced as raw machined blanks. The decoration steps (plating, PVD, lacquer) stay with local finishers close to the brands; what the supply chain needs upstream is a reliable, discreet blank producer. The working model is trial-order based entry: a first batch for dimensional and surface approval, then recurring series. Confidentiality is part of the service — customer part geometries and programs are never reused or disclosed. ## Typical component families and processes | Component (FR / EN) | Typical material | Process | Typical batch | bouchons de parfum, bruts (perfume cap blanks) | brass | turning + pre-polishing to Ra ≤ 0.2 | 5,000–50,000 pcs | bagues de cols de flacons (bottle-neck rings) | brass, aluminum | Swiss-type turning | 5,000–50,000 pcs | lests (counterweights) | brass, steel | turning / cold forging | 10,000+ pcs | mécanismes de pompes (pump mechanism parts) | 316, brass | Swiss-type turning | 5,000–50,000 pcs Pre-polishing to Ra ≤ 0.2 prepares the blanks for the finisher’s plating or PVD step; dimensional strategy accounts for the coating thickness added downstream. ## Workflow: drawing, sample approval and recurring series The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Tooling, program revisions and inspection records are kept on file so that call-offs remain consistent with the approved first article. Engineering changes — material substitutions, tolerance updates, plating or packaging changes — are handled as controlled changes against the same records. ## Quality and documentation DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Plating, cleanliness and packaging requirements are confirmed per drawing. ## FAQ Do you supply finished, decorated caps?No — we supply machined blanks pre-polished to the agreed surface value; plating, PVD and printing are performed by the finishers working with the brand or packager. How is confidentiality handled?Customer geometries, programs and order details are treated as confidential; an NDA can be signed before the first quotation. Why is the pre-polish value important?A pre-polish of Ra ≤ 0.2 reduces the finisher’s preparation work and improves plating adhesion; the exact value is confirmed per part family. Which batch sizes are typical?5,000–50,000 pieces per component family with recurring series; trial orders are possible for approval. ### Related Materials · Related Services · Related Case Studies [Related Materials: Copper ](https://www.sinbo-machining.com/products/materials/copper/)[Related Services: Cnc Machining ](https://www.sinbo-machining.com/services/cnc-machining/)[Related Case Studies: Eyeglass Hinges ](https://www.sinbo-machining.com/case/eyeglass-hinges/)[· Electrical Connectors ](https://www.sinbo-machining.com/case/electrical-connectors/)This page describes a representative application scenario for the luxury and cosmetics packaging industry, compiled from typical requirements of this vertical.
