Quality Inspection

Quality Inspection

Quality is not checked at the end.
It’s built into every step of our process.


At BestPro, inspection happens as part of everyday production — from the machining process to the final inspection. We want one thing: consistent quality, repeatable results, and absolutely no surprises.

In-Process Inspection

During machining, forming, or assembly, key dimensions and critical features are checked at defined stages.

● FAI for batch production
● Dimensional checks at critical operations
● Cards for processing, on which inspection data is input
● Process cards used to record inspection data
● Issues identified early, not post delivery

This method allows us to keep the batches homogeneous and eliminate rework or delays.

Final Inspection

All finished parts are subject to a final inspection according to the drawing and customer demands, before shipping.

● Dimensional verification
● Visual and surface condition checks
● Quantity and packaging confirmation
● Inspection reports available upon request
● After the inspection results are verified, parts are released for shipment.

Inspection Equipment

Our calibrated inspection equipment is designed for precision and repeat production.

CMM (Coordinate Measuring Machine) for complicated geometry and strict tolerances

Height gauges, micrometers, and calipers used to set the zero in a measuring device

Surface roughness measurement tools

Hardness testers (when required)

CMM inspections are typically utilized for critical dimensions and PPAP-style validation

Quality Inspection

Optional Advanced Inspection

(For Casting / Forging / MIM Parts)

Depending on material, process, and application, additional inspection methods can be applied when required.

Inspection Method Purpose Typical Applications
Ultrasonic Testing (UT) Detect internal cracks or inclusions Forgings, load-bearing parts
Radiographic Testing (RT / X-ray) Identify internal porosity or shrinkage Cast components
Magnetic Particle Inspection (MPI) Detect surface and near-surface cracks Carbon steel, alloy steel forgings
Dye Penetrant Inspection (PT) Reveal surface-opening defects Castings, MIM parts
Hardness Testing Verify heat treatment results Heat-treated components
PMI (Material Identification) Confirm material grade Critical or traceable parts
Microstructure Examination Evaluate grain structure Forged and MIM parts

These inspections are applied only when technically necessary or specified, helping balance quality assurance and cost.

Documentation & Traceability

Process flow cards archived by batch

Inspection records stored for traceability

Supports repeat orders and long-term consistency

This is how we maintain stable quality across different production runs.

Quality Inspection

BestPro Quality Mindset

We don’t treat inspections as a mere formality.

We look at it as a tool to safeguard our customers' projects.

It’s all about clear standards, useful checks, and straightforward communication — that is how we think about quality.
