What is the difference between shot peening and shot blasting?

Shot blasting and sand blasting remove material such as scale, rust or old coatings and create a surface profile. Shot peening is a cold-working process that uses controlled media impacts to induce a layer of compressive residual stress, which slows crack initiation and extends fatigue life. Peening is verified by Almen intensity and coverage, not by visual cleanliness.

Which specifications can KOSHIN shot peening machines be configured for?

KOSHIN systems are configured around the customer's governing specification, typically aerospace standards such as AMS 2430 or AMS 2432 for computer-monitored peening, with Almen intensity verified per SAE J442 and J443 and media controlled to the applicable media specification. Monitoring and data records are designed to support Nadcap-audited processes.

Can KOSHIN run trials on our parts before we purchase a machine?

Yes. KOSHIN operates in-house machines for experiment services, including Almen saturation curves, coverage studies and process development on customer samples. Validated parameters are then transferred into the production machine recipe, and contract processing is available for production batches.

What information is needed to prepare a machine proposal?

Provide workpiece dimensions and material, peening area, intensity and coverage requirements, media type and size, required production rate, available floor space and height, and any HS&E, Nadcap, emissions, noise or energy-efficiency requirements.

Does KOSHIN support overseas installation and after-sales service?

KOSHIN supports customers in more than 50 countries and regions with installation, commissioning, operator training, spare parts and lifecycle upgrades, coordinated from its Singapore engineering center.

Industry Whitepaper

Engineering Whitepaper: The Evolution of Automatic Glass Sandblasting

A comprehensive technical examination of surface roughness uniformity (Ra/Rz), hydrodynamic media separation, and particulate emissions mitigation in high-yield continuous processing.

The Mechanical Paradigm Shift: Closed-Loop Automation vs. Manual Processing

Modern glass manufacturing mandates ultra-consistent micro-abrasion profiles across large dimensional sheets. Traditional manual or pneumatic-pot sandblasting introduces non-uniform blast patterns, excessive subsurface micro-fissures, and catastrophic yield loss during thermal tempering stages.

KOSHIN Precision designs proprietary ODM Automatic Glass Sandblasting Machines incorporating CNC-synchronized multi-axis servo gantries, variable-frequency blast wheel or pressure-siphon arrays, and closed-loop continuous mass-flow monitoring. This eliminates human variability and produces repeatable, streak-free surface frosting across monolithic sheets exceeding 3300mm × 6000mm.

Subsurface Integrity: Controlled impingement energy prevents micro-cracking, preserving edge flexural strength (>120 MPa post-tempering).
Aerodynamic Media Reclaim: Dynamic multi-cyclone classifiers remove fractured glass particulates (<45 µm) down to <0.5% concentration in the active abrasive charge.

Technical Q&A

Frequently Asked Questions: Automatic Glass Sandblasting

In-depth technical answers addressing machine sizing, maintenance cycles, edge strength preservation, and custom ODM configurations.

What distinguishes an ODM automatic glass sandblasting machine from generic manual blasting cabinets?

Generic blast cabinets rely on operator hand control, resulting in uneven pressure application, varying nozzle-to-glass standoffs, and inconsistent frosting streaks that severely weaken glass impact resistance. An ODM automatic sandblasting machine from KOSHIN Precision employs closed-loop CNC or servo-controlled reciprocating gantry systems, digital pressure regulators, and automated continuous glass transport. This guarantees micron-level surface roughness (Ra) uniformity across 100% of the surface area, ensures absolute edge-to-edge repeatability, and eliminates manual labor fatigue.

Does automatic sandblasting affect glass mechanical strength or cause breakage during tempering?

Improper, uncalibrated abrasive blasting can cause deep micro-cracks and thermal hot spots that induce structural failure during subsequent tempering furnace cycles. KOSHIN systems utilize precision variable-frequency blast wheel or optimized low-pressure siphon arrays paired with tightly graded abrasive media. This generates a shallow, uniform compressive residual-stress layer rather than jagged fissures, preserving post-tempering flexural strength (>120 MPa) in compliance with EN 12150 and ASTM C1048 standards.

How does KOSHIN handle dust filtration and environmental safety compliance?

Our machines operate under continuous negative air pressure within a hermetically sealed chamber. The integrated air handling system features reverse pulse-jet PTFE-membrane cartridge dust collectors that achieve particulate emissions of less than 1.5 mg/Nm³, significantly stricter than international OSHA and EU environmental standards. Heavy-duty polyurethane internal wall lining mitigates acoustic reverberation, keeping continuous operating sound below 74 dBA.

What abrasive media types can be processed in KOSHIN automatic sandblasting machines?

KOSHIN systems can be configured for diverse industrial media, including white or brown fused aluminum oxide (corundum), silicon carbide, glass microspheres, and ceramic beads ranging from 60 mesh to 320 mesh. Our dynamic cyclone classification system continuously screens out shattered dust and oversized contamination, ensuring consistent abrasive sizing and high-efficiency recycling.

What is the standard lead time, FAT protocol, and overseas installation support?

Typical ODM production lead time ranges from 8 to 14 weeks depending on customized bed dimensions and automation degree. Prior to dispatch, a comprehensive Factory Acceptance Test (FAT) is conducted using client-supplied test glass to verify cycle time, Ra roughness values, and mechanical tolerances. Following shipment, KOSHIN deploys factory-trained field service engineers for on-site commissioning, Site Acceptance Testing (SAT), and comprehensive operational/maintenance staff training.
