Frequently Asked Questions on Large Blast Cabinets & Peening
Direct answers from KOSHIN’s Senior Application Engineering Directorate on equipment specifications, standards compliance, and process qualification.
What is the core technical difference between shot peening and sand blasting?
Sand blasting and abrasive blasting are surface cleaning or profiling processes that cut away scales, rust, and contaminants to create a specific surface roughness (Ra/Rz). In contrast, controlled shot peening is an elastoplastic cold-working method using spherical media to induce a tailored layer of compressive residual stress, which delays micro-crack initiation and dramatically extends component fatigue life. Peening acceptance is governed by Almen arc height intensity and coverage percentages rather than visual cleanliness.
Which specifications can KOSHIN large sand blast and peening systems comply with?
KOSHIN systems can be configured around any client specification. Common standards include AMS 2430, AMS 2432 (computer-monitored peening), Boeing BAC 5730, Safran DMR 71-110, Rolls-Royce RPS 428, and general industrial standards like ISO 8501-1 for blast profiling. Continuous closed-loop parameters guarantee that quality records pass rigorous Nadcap audits.
Can KOSHIN run pre-purchase trials and develop saturation curves on our workpieces?
Yes. KOSHIN maintains in-house automated cabinets and robotic peening systems solely dedicated to contract testing, process trials, and Almen saturation curve validation. Once optimal blast angles, nozzle standoff, media flow rates, and pressures are proven, the recipe is directly transferred to your production machine PLC prior to factory sign-off.
What crucial data is required to generate an OEM blast cabinet proposal?
Please provide maximum workpiece dimensions and weight, base metal alloy and heat treatment state, required surface target (surface profile Ra/Rz or Almen intensity and coverage), media size and type (e.g., cast steel shot, ceramic bead, aluminum oxide), target cycle time per batch, facility footprint limits, and local electrical/environmental standards.
