Magnetic Jewelry CAD Review Before Sampling: A Practical B2B Process Guide
- Start with a complete brief. RainSo provides the initial CAD direction within 48 hours after the brief is confirmed.
- Review geometry, dimensions, magnet recess, clasp fit, finish notes, and the exact deliverable before sampling.
- Standard custom samples are generally planned within 30–45 days after CAD direction, once material, tooling, and sample requirements are set.

A magnetic jewelry CAD review checks whether the buyer’s brief has been translated correctly into geometry, dimensions, magnet recesses, clasp relationships, logo placement, and finish notes before physical sampling begins.
Start with the Brief, Not the Drawing
Buyers often ask for a magnetic jewelry CAD review before they have supplied enough information for one. RainSo starts with the brief instead. Otherwise, the first technical exchange becomes a clarification loop rather than a useful review.
RainSo was established in 2007, with commercial coordination in Guangzhou and production resources in Dongguan. In a CAD review, the lesson is simple: describe the product, not just the request for a drawing. For a bracelet or necklace, a useful brief covers the category, reference dimensions, material family, magnet placement, clasp type, finish direction, and logo placement if private label is part of the project. If one of those points is unclear, state that early.
Checklist: What to Include in the Feasible Brief
Use this list as a working brief for a magnetic jewelry CAD review. Missing details can delay the CAD direction or lead to avoidable revisions:
- Product category: bracelet, ring, necklace, earrings, or anklet
- Material family: 316L stainless steel, copper, titanium, or ceramic
- Product dimensions: overall profile, target reference, bracelet inner circumference or ring size, and critical tolerances
- Magnet specification: diameter, thickness, quantity, grade if specified, orientation or polarity, and intended retention method
- Magnet recess: hole position, spacing, depth, and distance from the visible surface
- Clasp type, clearance, closure-fit direction, and opening direction
- Finish direction such as polished, matte, or embossed
- Logo size, engraving depth, and required safe margin
- Edge treatment and surfaces that contact the skin
- Whether polishing or plating will affect final dimensions
- Required CAD deliverables: front view, side view, cross-section, or 3D model
- MOQ or annual order target
- Private-label logo file and placement if applicable
- Packaging requirement if the sample must include final presentation
It is perfectly fine to mark fields as “Unknown.” Identifying those gaps before CAD begins avoids redesigning the tooling later.
The 48-Hour Initial CAD Direction
After the brief is complete and feasible, RainSo sends the initial CAD direction. Treat it as the first engineering review, not a final drawing, mold-ready file, physical sample, or production commitment.
Depending on the project, the direction may show part geometry, a magnet recess, the closure relationship, or key dimensions. Before using the file for a sourcing or quality decision, confirm what that specific deliverable covers for the SKU.
What to Review in a Magnetic Jewelry CAD Review
At this stage, check whether the manufacturer’s interpretation matches the product you asked for. Review the proportions, key tolerances, bracelet inner circumference or ring size, magnet hole position and depth, magnet-to-surface distance, clasp clearance, opening direction, logo placement and engraving depth, edge treatment, material label, and finish notes.
If you need a full 3D render, printable file, or color-accurate preview, put that requirement in the brief. The published 48-hour point covers the initial CAD direction. Other deliverables must be confirmed for the project.
From CAD Direction to Sample Planning Window
Sample timing is a separate stage. RainSo generally plans standard custom samples within 30–45 days after CAD direction, material, tooling, and sample requirements are confirmed. Complex structures, additional tooling, extra revisions, or special packaging can extend the timeline.
The sample clock starts after the technical direction has been reviewed and the production variables are locked. It does not start when the initial CAD direction is delivered.
Where CAD Review Sits in the Larger Production Process
A magnetic jewelry CAD review is the bridge between brief confirmation and sample planning. After the CAD direction is approved, any required tooling and sample work can begin. Once the physical sample is approved, the confirmed structure, finish, magnet placement, clasp function, and packaging become the reference for production and QC.
| Stage | Buyer provides or approves | RainSo reviews | Output |
|---|---|---|---|
| Project brief | Category, dimensions, material, magnet and clasp requirements | Completeness and feasibility | Confirmed brief |
| Initial CAD direction | Feedback on proportions and structure | Geometry, recesses, fit and key dimensions | Initial CAD direction |
| CAD confirmation | Dimensions, material, logo and structural details | Manufacturability and required revisions | Approved technical direction |
| Sample planning | Tooling, finish and sample requirements | Sample scope and schedule | Confirmed sample plan |
| Physical sample | Sample approval or revision comments | Fit, structure, finish and function | Production reference |
Confirmations That Move the Project Forward
Two decisions move the project forward. First, RainSo confirms that the brief is complete and feasible. Later, the buyer and production team confirm the CAD direction, material, tooling, and sample requirements. Each step has a different purpose.
If the material changes from stainless steel to ceramic, or the clasp type changes, the CAD direction may need a revision before sampling. RainSo’s current published material families are 316L stainless steel, copper, titanium, and ceramic. Current catalog categories include bracelets, rings, necklaces, earrings, and anklets.
CAD Review for OEM, ODM, and Private-Label Projects
A magnetic jewelry CAD review supports both existing-design customization and customer-original development. Light customization usually plans around 50–100 pieces per style. Customer-original development usually plans around 100 pieces per style and requires a mould/tooling fee quoted per design. Final MOQ follows the structure, tooling, material, and packaging.
A buyer changing the finish on an existing bracelet may need limited CAD work. A buyer submitting a new bracelet drawing with a custom clasp and magnet recess needs a fuller technical review before sampling. The difference is how much of the structure is new.
Private-label logo engraving is available at 100+ units and included under confirmed project conditions when applicable. Product suitability, file quality, logo size, and placement are reviewed before CAD and sampling. For logo conditions, visit private-label branding.
How MOQ and Packaging Affect the CAD Review
MOQ can decide whether a buyer adapts an existing style or starts a new CAD review. Stock orders normally follow a separate route without CAD development; review the wholesale purchasing guide before comparing stock and custom paths.
Custom packaging is quoted according to the box, insert, printed materials, quantity, and shipping requirements. If packaging is part of the sample plan, confirm that scope before treating the sample date as final. See Custom packaging solutions.
What the Initial CAD Direction Does and Does Not Cover
This initial CAD direction does not commit RainSo to a final CAD file, sample delivery, or production dispatch. The 30–45 day figure is a sample-planning range. Final timing is confirmed for the project.
CAD approval confirms design geometry and fit. Product testing, market-specific compliance documents, and ISO 9001 quality-management scope are reviewed separately. See the materials and compliance guide when the project needs product-specific documentation.
How to Ask the Right Questions Before Sampling
Ask RainSo to confirm what a magnetic jewelry CAD review includes for the SKU, how many revision rounds are included in that stage, what type of change would require a new quotation or timeline, what must be settled before the 30–45 day sample window begins, and whether private-label engraving fits the project volume and file conditions.
That question set separates an initial technical direction from a final CAD approval or sample shipping date.
Final Step: Send a Feasible Project Brief
Send a complete brief through the Inquiry page for your magnetic jewelry CAD review. Include category, material family, reference dimensions, magnet requirements, clasp, finish direction, and MOQ target. If private label or custom packaging is part of the plan, state that clearly before CAD review begins.
For capability details, review OEM and ODM capability. For logo engraving conditions, visit private-label route. For packaging as a service, see Custom packaging solutions.
Frequently Asked Questions
Does RainSo commit to sample delivery 30 days after CAD review?
No. The standard planning range is 30–45 days after CAD direction and requirements are set. Complex work can take longer, and the final timing is confirmed for the project.
What does a magnetic jewelry CAD review include at the 48-hour stage?
It is the first technical direction after a complete and feasible brief. Depending on the project, it may cover proportions, dimensions, magnet placement, clasp fit, and finish notes. It is not automatically a final drawing or sample commitment.
Is private-label logo engraving included with every CAD review?
No. Logo engraving is available at 100+ units under confirmed project conditions. Product suitability, file quality, logo size, placement, and order scope are reviewed first.
When does the 30–45 day sample planning window start?
After CAD direction, material, tooling, and sample requirements are confirmed. The initial CAD direction alone does not start the sample window. Extra revisions or complex structures may add time.
Can a buyer use CAD review for stock wholesale orders?
Stock orders follow a separate path. CAD review applies to custom OEM/ODM or private-label development. Review the wholesale purchasing guide for the stock-order route.
Does RainSo provide a final 3D render or printable file at the 48-hour stage?
Not automatically. If you need a full render, printable file, or approved 3D view, include it in the brief and confirm that deliverable for the project.
What are typical custom MOQ ranges before sampling?
Existing-design customization generally follows a lower planning range than original development. The confirmed MOQ depends on structure, tooling, material, and packaging and is stated in the quotation.
Does CAD review confirm material compliance?
No. CAD covers design geometry and fit. Product testing and market-specific documents are reviewed separately for the applicable product, material, batch, and destination.
