PRODUCT SHAPE / BLOCK MAGNETS

Custom Neodymium Block Magnets to Engineering Specification

A block magnet route for length, width, thickness, edge condition and the fit or clearance the assembly depends on.

Drawing-led review preferred. A clear written requirement can start the discussion when a drawing is not ready.

01 / BLOCK ENVELOPE

Define the block before production.

The three primary dimensions are only the start. Add reference faces, edge breaks, chamfers, fit, clearance and any orientation marks needed by the assembly.

BLOCK GEOMETRY / ENVELOPE AND REFERENCE FACES
01

Length, width and thickness

State the finished envelope and the dimension that controls the assembly.

02

Edge and corner condition

Call out chamfers, radii or sharp-edge restrictions.

03

Fit and clearance

Identify the mating feature and the critical clearance.

04

Magnetization direction

Mark the required pole orientation against a reference face.

02 / MATERIAL DECISIONS

Carry the application into grade and coating.

The stated material range is a starting point. The final grade, coating and dimensional basis remain conditional to the application and approved specification.

Grade rangeN25 to N52Stated range, project dependent
Dimension range1 to 250 mmProduct-related reference range
ToleranceTypical ±0.1 mmRoute-dependent review
CoatingNickel, zinc, epoxyApplication and environment dependent

03 / MANUFACTURING AND QUALITY

Let the feature drive the route.

Machining, coating, magnetization and inspection should follow the dimensions and assembly features that matter. A block drawing makes those handoffs explicit.

MANUFACTURING CONSEQUENCE / FEATURE AND FINISH
01

Machining

Critical faces and edges are reviewed against the process route.

Review manufacturing
02

Coating

Selected treatment must work with fit and operating environment.

03

Magnetization

Direction and polarity travel with the latest drawing.

04

Inspection

Release checks stay adjacent to the dimensions.

Review quality

04 / ENGINEERING HANDOFF

Make the block drawing reviewable.

Share the latest drawing, application, quantity, coating and inspection expectations. A clear written description can start the discussion when the drawing is still in progress.

01

Part definition

Envelope, features, reference faces and tolerance.

02

Application context

Assembly position, environment and magnetic function.

03

Commercial basis

Quantity, annual usage and sample expectations.

BLOCK MAGNET / REVIEW BASIS

Start with the block envelope.

The useful first step is the geometry that controls the assembly.
