Industrial surface preparation
Sandblasting that prepares your parts for what comes next
BGCNC provides industrial sandblasting for metal components that need a clean, consistent surface, a coating-ready profile, or a specified matte finish. We coordinate blasting with machining and downstream finishing to keep the final surface aligned with your requirements.
From raw material sourcing and machining coordination to final coating and delivery.
One coordinated surface workflow
Blasting → inspection → secondary finishing
Start with the required finish
A surface profile built around your end use
Sandblasting is usually one step in a larger manufacturing lifecycle. Our engineering team reviews the part and target finish to match the process to the job.
Create a profile for downstream coating
A controlled anchor pattern can support bond strength for powder coating, anodizing, or painting. We consider the intended finish when determining the appropriate media and process settings.
Smooth edges and remove machining burrs
Blasting can help remove sharp edges and burrs from CNC-milled or laser-cut parts, with the process selected to suit the component and its requirements.
Restore a consistent surface after processing
For parts affected by heat treatment or welding, blasting can remove scale and oxidation and help return the surface to a more uniform state before subsequent operations.
Achieve a consistent matte appearance
A uniform matte finish can help reduce the visibility of minor surface imperfections or tool marks when that appearance is the target for the finished part.
Media options include glass beads, aluminum oxide, and steel grit, matched to the material and surface requirements.
Integrated finishing solutions
One point of contact from engineering review to final finish
Coordinating machining, blasting, and coating across separate vendors can create communication gaps and inconsistent quality. We manage the sequence and handoffs so requirements travel with your parts.
-
01 / Review
Engineering assessment
We analyze your CAD drawings and assess whether sandblasting is a cost-effective route to the desired finish.
-
02 / Match
Material and process selection
Media and settings are considered against your component material—aluminum, steel, stainless steel, or titanium—and surface target.
-
03 / Inspect
Quality check before next steps
Parts are inspected after blasting against the technical requirements before moving on to painting, assembly, or other operations.
-
04 / Coordinate
Managed supply chain handoffs
We oversee transit between CNC partners and specialist finishing facilities to support predictable lead times and consistent quality.
Design for the intended result
Is sandblasting right for your project?
Our manufacturing engineers help identify process considerations early, so surface preparation works with your material, tolerances, and production volume.
Discuss your part requirementsMaterial hardness and part geometry
Different media affect materials differently. Process selection should clean the surface without damaging or warping thin-walled components.
Tolerances and material removal
Sandblasting is abrasive and removes a small amount of material. For tight tolerances, such as ±0.01 mm, account for material removal during the initial machining stage.
Volume and unit cost targets
For high-volume production, we help balance surface requirements with process efficiency and your total unit cost targets.
Beyond sandblasting
A broader finishing and post-processing toolkit
Coordinate surface treatments and follow-on work as part of one manufacturing plan.
Surface finishing
Anodizing, powder coating, electroplating, passivation, and chemical film.
Heat treatment
Hardening, tempering, and stress relieving.
Assembly and delivery
Kitting, sub-assembly, and custom packaging.
Manufacturing support
Scale from prototype to production with surface requirements in view
BGCNC acts as an extension of your engineering team, coordinating the complexities of the China supply chain so you can focus on product design and development. We provide technical oversight for low-volume prototypes, production runs, and complex BOMs with multiple finishing requirements.
