Quality Inspection & Testing
Full filter quality inspection from PLEATPURE — incoming media checks, in-process control, final testing and batch documentation before every shipment.
WHAT WE OFFER
Quality Inspection & Testing Services
Incoming Material Inspection
Media grade, basis weight, pleat geometry and end cap materials verified against the approved specification on arrival.
In-Process Quality Control
Pleating, cutting, welding and assembly monitored at each production station, with first-article checks at line start.
Final Inspection Before Shipment
Dimensional checks, bubble point and burst tests on sampled production, plus 100 percent visual checks of seals and outer wraps.
Filter Testing Equipment
Bubble point testers, burst test rigs, flow benches, micrometers and calibrated gauges used at every inspection stage.
Batch Documentation
Test reports, certificates of conformance and material certificates compiled for every batch and shipped with the goods.
Traceability & Records
Batch records link media lots, production data and inspection results, so any issue traces back to its source.
OUR PROCESS
From Inquiry to Delivery
Specification Review
Acceptance criteria, test methods and sample rates agreed before production starts.
Incoming Inspection
Media and components verified against the specification, with reject lots quarantined and returned.
Process Control
In-line checks at every stage — pleat count, seal integrity, weld quality and dimensional drift.
Final QC & Shipment
Final inspection, batch documentation and release for shipping, with records kept for seven years.
WHEN TO USE THIS
Challenges This Solves
Early Filter Failure
Elements failing fast or passing dirt usually trace to media, seals or assembly. Batch inspection data pinpoints the cause.
Audits & Compliance
Buyers and auditors ask for documented quality. Batch records and test reports answer the questions without delay.
Inconsistent Supplier Quality
Mixed results across batches erode trust in the supply chain. A documented incoming and in-process inspection program levels out the variation.
FAQ
Quality Inspection & Testing — FAQ
What testing do you perform on filter elements?
Dimensional verification, bubble point, burst strength, media integrity and flow checks per batch. Test reports ship with every order.
Do you test to ISO standards?
Hydraulic media is tested per ISO 16889 for beta ratio and dirt-holding capacity (typical). Dimensional checks follow the OEM reference dimensions.
Can you provide test certificates?
Yes. Batch test reports and certificates of conformance are standard, and third-party inspection can be arranged at the buyer's request.
Can you inspect pre-production samples?
Yes. Samples are checked for dimensions, media and assembly against the approved spec before mass production begins, using AQL sampling (typical).
