metal bottle-cap circular-blanking page
Bottle-cap blanking must start from the cap blank, coated/printed surface and downstream drawing route; lateral nesting is acceptable only when material handling and surface trials support it.
Scope and Evidence Status
This URL is written as a bounded technical decision page for zigzag feeding for metal bottle-cap blanking. It does not claim a confidential customer result, certified finished product or universal machine capability. Any future case-study statement needs the records listed below.
Application-Specific Process Route
The labeled route below is a conceptual engineering diagram—not a photograph of a delivered project. It makes the current page intent visible without presenting generic equipment images as application proof.
Inputs to Freeze Before Selection
- Bottle-cap blank drawing and downstream draw/forming route
- Metal, temper, thickness, coating/print and coil width
- No-contact/low-mark zones and cleaning requirements
- Blank diameter, web, edge margins and nesting coordinates
- Press/die window, traverse, scrap and blank discharge
- Coating, edge, blank geometry and first-off inspection
Context Images and Their Limits
Engineering Decision and Verification Table
| Decision gate | How to verify | Required record |
|---|---|---|
| Surface contact | Trial production-coated strip through the path | Before/after samples |
| Layout | Verify margins and extreme coordinates | Controlled nesting sheet |
| Discharge | Run blank/scrap separation without scratching | Trial record |
| Blank result | Inspect coating and specified blank features | Sample report |
Page-Specific Method
Work through the four gates below with the production drawing, material and real machine interface. Each gate produces a record that can be independently reviewed instead of relying on a generic industry claim.
Surface contact
Trial production-coated strip through the path Record: Before/after samples
Layout
Verify margins and extreme coordinates Record: Controlled nesting sheet
Discharge
Run blank/scrap separation without scratching Record: Trial record
Blank result
Inspect coating and specified blank features Record: Sample report
Failure Modes, Stop Conditions and Boundaries
- Coating abrasion: Stop on repeating roll/guide marks
- Blank-to-cap overclaim: Downstream drawing determines finished cap form
- Generic image use: Context photos do not prove a bottle-cap application
Acceptance Record for This Page
Freeze the released drawing and material revision, machine configuration, interface list, recipe, sample plan and measuring method. Record exceptions and the safe restart route. A publishable result must identify the tested configuration; otherwise retain this page as an engineering guide.
Source and Verification Boundary
HENLI zigzag servo feeder category. Model travel and motion limits must be confirmed against the current quotation; the category does not prove a material-saving percentage.
