Abrasive Blasting Done Right

At Pi Fabricators we know that you want surface prep done right so your parts can be ready for the next step in your process. In order to do that, you need a supplier with the right blasting equipment. The problem is not a lot of shops have the equipment or expertise to blast your parts right which leads to surface prep that risks harming the quality of downstream processes such as painting. We believe you should have a supplier that can blast your parts right. We understand the importance of good surface prep which is why we offer abrasive blasting services tailored to your needs.

After seeing coatings fail from inadequate prep, excellent surface preparation became our non-negotiable.

To meet the stringent surface prep quality requirements of thermal spray we invested in multiple surface preparation technologies including a manual abrasive blasting cabinet.

Why Abrasively Blast Parts?

Coating Adhesion: Creates a textured surface for paint, powder coating, adhesives, and other finishes to bond effectively, increasing longevity and preventing premature failure.

Pre-Welding Cleanliness: Removes contaminants, rust, and old coatings to ensure sound, uncompromised welds.

Surface Profiling: Produces a specific surface roughness or profile for optimal performance in various applications such as anti-slip surfaces or cosmetic finishes.

Compared to Grinding Abrasive Blasting is More Efficient at:

Rust Removal: Effectively strips away corrosion, restoring metal surfaces to their original condition.

Paint Removal: Blasts away old paint or coatings to prepare for new finishes or expose the raw material.

Scale Removal: Eliminates mill scale buildup or scale from heat treating or other manufacturing processes.

General Contaminant Removal: Removes stubborn dirt, grease, grime, and other residues that standard cleaning can't.

A multitude of surface finishes can be achieved with different abrasives

Need an aggressive anchor pattern: Crushed steel shot may be a good choice.

Need a peened surface to increase fatigue resistance: Spherical steel shot is likely a good choice.

Need a gentle clean of aluminum or plastic parts: Walnut shells could be a good option.

To name just a few

Shot Peening with abrasive Blasting

With our blasting equipment we can shot peen your small parts. This can significantly improve the fatigue life of your steel parts by introducing compressive residual stress into the surface layer. Here's how it works:

  1. Surface Bombardment: Shot peening bombards the steel surface with small spherical metallic, ceramic, or glass beads. The force of the impact creates tiny indentations on the surface.
  2. Compressive Stress Generation: These indentations don't just leave marks, they force the metal to compress beneath the impact zone. This creates a layer of compressive residual stress below the surface.
  3. Resistance to Crack Initiation: During regular operation, steel parts experience cyclic loading, which can cause microscopic cracks to initiate at the surface. The compressive stress layer in shot peening acts like a shield, counteracting the pulling forces (tensile stress) that tend to open these cracks.
  4. Slower Crack Growth (if present): Even if a small crack manages to form, the compressive stress field can slow its growth. This gives the material more time to resist failure and allows for earlier detection during inspections.
