Bead blasted

Controlled media blasting creates a more uniform matte texture.

ENGINEERING DOSSIER

Specify blast media intent, texture reference and surfaces that must stay controlled

Bead blasting is a geometry-dependent texture operation

Media access, edge exposure and protected interfaces determine where a uniform matte result is realistic.

Sequence and substrate evidence

Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable.

Acceptance belongs to named surfaces

Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation.

Release inputs for Bead blasted

Specify base material, media intent, texture reference, cosmetic zones and masking.

APPEARANCE AND FUNCTION

Appearance, function and substrate boundary for Bead blasted

Media access, edge exposure and protected interfaces determine where a uniform matte result is realistic.

Function: Protection, contact, wear or interface role. Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation.

DECISION CONTROLS

Protected interfaces and acceptance controls for Bead blasted

Sequence and substrate evidence

Confirm substrate alloy/grade, condition and any preparation specific to Bead blasted. Compatibility must be checked against the named base material, not a generic family.

Acceptance belongs to named surfaces

Map cosmetic zones, datums, fits, threads, electrical contacts, seal lands and areas that must remain uncoated or require controlled build for Bead blasted.

Release inputs for Bead blasted

Specify Bead blasted by process/standard where applicable, appearance reference, coverage, masking map, thickness or build requirement if relevant, and protected critical dimensions.

PROJECT-SPECIFIC DECISION DATA

Finish map before Bead blasted release

Confirm substrate, preparation, appearance/function, protected zones and inspection evidence; do not infer acceptance from the finish name alone.

Decision item	What must be resolved	Evidence at release
Bead blasting is a geometry-dependent texture operation	Media access, edge exposure and protected interfaces determine where a uniform matte result is realistic.	Reference, texture, color or toolpath
Sequence and substrate evidence	Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable.	Protection, contact, wear or interface role
Acceptance belongs to named surfaces	Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation.	Coverage, masking and critical features
Release inputs for Bead blasted	Specify base material, media intent, texture reference, cosmetic zones and masking.	Coverage, masking and critical features

INSPECTION AND ACCEPTANCE

Inspect Bead blasted against the named reference and functional interfaces

Inspect Bead blasted against the agreed sample/reference, coverage and surface zones; verify masked interfaces, thread function, fit-sensitive dimensions and any required adhesion/corrosion evidence.

Geometry, access, edges, recesses and part-to-part variation can affect the result; use a named reference and surface map.

DECISION QUESTIONS

Bead blasted specification and inspection questions

What must be defined before reviewing Bead blasted?

Media access, edge exposure and protected interfaces determine where a uniform matte result is realistic. Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable.

Which interfaces need project-specific confirmation?

Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation. Geometry, access, edges, recesses and part-to-part variation can affect the result; use a named reference and surface map.

What should accompany release?

Specify base material, media intent, texture reference, cosmetic zones and masking. Coverage, masking and critical features

PROJECT BRIEF

Bead blasted finish map and acceptance checklist

Use these page-specific checks to define substrate, preparation, appearance or function, protected zones and acceptance evidence for Bead blasted. Do not release from the finish name alone.

Pretreatment and substrate — Bead blasting is a geometry-dependent texture operation

Media access, edge exposure and protected interfaces determine where a uniform matte result is realistic. Record substrate and pretreatment on a controlled surface map.

Appearance or function — Sequence and substrate evidence

Record the base material, preparation, operation order and any approved appearance reference so the visible result remains explainable. Attach the named appearance or functional reference used for acceptance.

Masking and acceptance — Acceptance belongs to named surfaces

Use a surface map for cosmetic zones, contacts, threads, fits, masking and geometry-dependent variation. Mark masking, fit-sensitive zones and the inspection record required at release.
