Resolve 8 Blasting Risks Before Processing
Plan your abrasive finish without losing the interfaces your assembly depends on.
Choose the Route for Your Actual Substrate
Sandblasting metal parts requires a material-specific review. Define whether you need cleaning, texture or preparation for another finish; do not assume one media route suits every alloy.
| Your input | Material, incoming surface and intended next operation. |
|---|---|
| Our review | Suitable abrasive route and representative trial. |
Specify More Than a Grit Number
Aluminum oxide blasting, glass bead blasting and other media differ in material and particle shape. A grade number needs its grading system and media identity. Pressure, exposure and geometry also affect the outcome.
| Your input | Media material, grade system and approved sample. |
|---|---|
| Our review | Process suitability and controlled surface result. |
Protect Your Threads Before They Enter Blasting
Mark threaded holes, studs and assembly interfaces on your drawing before blasting. Agree which areas must be masked so your specified surface finish does not compromise the thread fit your assembly needs. Fine abrasive is not a substitute for masking.
| Your input | Thread callout, engagement, blind holes and unblasted zones. |
|---|---|
| Our review | Secure plugs or caps, post-blast cleaning and functional verification. |
Keep Material Removal Away from Critical Fits
Precision abrasive blasting can affect dimensions, edge sharpness and surface texture. Mark bearing seats, sealing faces and final-fit requirements; confirm what is protected and what is measured.
| Your input | Final dimensions, datums and edge requirements. |
|---|---|
| Our review | Protection, exposure and finished-part checks. |
Review Distortion Risk Before Your Trial
Thin panels, long flanges and unsupported features need review for the actual blasting method. Use a representative sample when flatness or assembly alignment matters.
| Your input | Wall thickness, flatness and support requirements. |
|---|---|
| Our review | Feasible process, trial and acceptance method. |
Approve Your Surface with an Agreed Basis
Sandblasting surface roughness is not determined by grit alone. Define required parameters and measurement conditions where specified, plus an appearance sample for visible faces.
| Your input | Roughness callout, location and visual reference. |
|---|---|
| Our review | Media/process trial and suitable measurement. |
Remove Abrasive Before Your Parts Are Assembled
Inspect recesses, blind holes and thread roots after blasting. Agree a cleaning method and cleanliness acceptance appropriate to the geometry and downstream use.
| Your input | Trapped spaces and permitted residues. |
|---|---|
| Our review | Access, cleaning, inspection and assembly fit. |
Coordinate Your Blast and Coating Sequence
For sandblasting before powder coating, agree preparation and handling with the coating processor. Other chemical finishes also require compatible preparation; do not assume a generic bead blast is suitable.
| Your input | Next finish, cleanliness and timing requirements. |
|---|---|
| Our review | Compatible preparation, storage and release condition. |
Confirm Your Material and Starting Surface
Material names alone do not define the blasting process. Review the actual grade, geometry and surface state.
Aluminum
Review alloy, thin walls, cosmetic faces and protected precision features.
Stainless Steel
Specify grade, texture and contamination-control requirements.
Carbon & Alloy Steel
For sandblasting steel, identify rust, scale, previous coatings and the required next finish.
Cast Components
Disclose casting skin and defects; blasting is not a repair for porosity.
Formed & Welded Parts
Review distortion sensitivity, weld zones and visible surface transitions.
Existing Coatings
For abrasive blasting coating removal, disclose the coating and acceptable substrate condition; removal feasibility is confirmed by review.
Glass bead blasting services, grit blasting services and other media blasting services are not automatically interchangeable. Confirm material, media, equipment scope and acceptance for your part.
Compare the Same Surface Scope Before Ordering

Answers Before Your First Order
What is sandblasting?
It is a common name for abrasive blasting, in which media is directed at a surface for a defined treatment purpose. The name does not specify the abrasive material. Agree the actual media and required outcome for your part.
Sandblasting vs bead blasting: which fits your part?
Compare the substrate, purpose and required texture. Bead blasting typically uses rounded media, while other grit routes use different particle shapes and cutting behavior. Neither service name alone defines the acceptable result.
Can 150 or 220 grit blasting replace thread masking?
No. A finer grade may produce a different surface effect under comparable conditions, but it does not prevent abrasive entering threads or establish an acceptable assembly fit. Specify masking and the required verification separately. Within the same media and grading system, 220 is generally finer than 150; that does not guarantee negligible thread effects.
Should a screw reach the physical bottom of a blind hole?
Use the engagement depth and assembly condition specified on your drawing. Blind holes normally need allowance for incomplete threads, clearance and the fastener length; physical bottoming is not a universal acceptance requirement.
Does sandblasting change dimensions?
It can affect dimensions, edge condition and surface texture. Mark critical fits and required unblasted features. Agree suitable protection, process trials and finished-part inspection rather than assuming zero change.
Can sandblasting damage aluminum?
An unsuitable abrasive or process can affect the surface, thin features and critical geometry. Review the actual alloy, wall stiffness, media and sample before processing.
What surface roughness does sandblasting produce?
No single roughness value applies to all media and parts. Specify the parameter, measurement location and acceptance basis, then review a representative sample with the chosen process.
Can sandblasting remove machining marks?
It may change their visibility, but deep marks can remain and more aggressive removal can affect geometry. Agree the starting surface, desired appearance and permitted material removal before approving a sample.
Abrasive blasting vs shot peening: are they equivalent?
No. Controlled shot peening has its own specified process and verification requirements. A cleaning or cosmetic blasting operation should not be represented as verified shot-peening performance.
How soon should steel be coated after blasting?
Coordinate the timing, environment and storage with the next coating processor and applicable preparation requirements. Do not use a universal waiting interval for every steel or coating system.
How much does sandblasting cost?
Material, starting surface, geometry, media, masking, cleaning, inspection and quantity affect cost. Compare the same delivered scope and ask for any lot or setup charges separately.
How long does sandblasting take?
Confirm actual media/process availability, sample review, cleaning, next operation and delivery with your quote. No universal lead time or sandblasting minimum order applies to every project.
