Quality Control for Food Processing Blades
Quality control is built around the drawing, old sample or confirmed specification: material, hardness, thickness, hole position, bevel angle, edge condition and packing protection.
Inspection Principles
For custom and replacement blades, the important question is not only whether a blade looks sharp. It must fit the machine, cut consistently and survive cleaning and repeated production.
What Can Be Confirmed Before Production
The final inspection standard should be agreed from the drawing, sample or equipment model before production starts.

Heat Treatment And Hardness
Check hardness after heat treatment according to the target range confirmed for the blade type and cutting load.
Profile, Hole And Slot Position
Check outer profile, mounting holes, slots, bore size and key mounting dimensions against drawing or old blade sample.
Thickness, Flatness And Straightness
Review blade thickness, flatness, straightness and deformation risk before edge finishing and packing.
Bevel, Edge And Tooth Geometry
Inspect bevel direction, edge angle, burr condition, tooth pitch or perforation pitch according to blade function.
Surface Finish And Rust Protection
Check polishing, scratches, rust spots, cleaning marks and apply anti-rust packing suitable for transport.

การตรวจสอบ SEM Edge Observation
Scanning electron microscope images help review edge morphology, fracture trace, wear condition and abnormal surface features.

EDS Composition Analysis
Element spectrum analysis checks whether abnormal elements appear around the inspected area and supports material review.

Metallographic Structure
Microstructure observation helps review heat treatment condition, matrix uniformity and obvious carbide segregation.
04 / Evidence
Hardness Analysis
Hardness readings across different positions help judge heat treatment consistency and whether the target range is suitable.
