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.

Inspection Principles

What Can Be Confirmed Before Production

The final inspection standard should be agreed from the drawing, sample or equipment model before production starts.

Drawing dimensionsOld blade sampleEquipment modelMaterial requestHardness targetPacking requirement
01

Material And Order Requirement

Confirm steel type, thickness, surface request and food-contact working environment against the order requirement.

02

Heat Treatment And Hardness

Check hardness after heat treatment according to the target range confirmed for the blade type and cutting load.

03

Profile, Hole And Slot Position

Check outer profile, mounting holes, slots, bore size and key mounting dimensions against drawing or old blade sample.

04

Thickness, Flatness And Straightness

Review blade thickness, flatness, straightness and deformation risk before edge finishing and packing.

05

Bevel, Edge And Tooth Geometry

Inspect bevel direction, edge angle, burr condition, tooth pitch or perforation pitch according to blade function.

06

Surface Finish And Rust Protection

Check polishing, scratches, rust spots, cleaning marks and apply anti-rust packing suitable for transport.

SEM Edge Observation

SEM Edge Observation

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

EDS Composition Analysis
02 / Evidence

EDS Composition Analysis

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

Metallographic Structure
03 / Evidence

Metallographic Structure

Microstructure observation helps review heat treatment condition, matrix uniformity and obvious carbide segregation.

Hardness Analysis
04 / Evidence

Hardness Analysis

Hardness readings across different positions help judge heat treatment consistency and whether the target range is suitable.
