Quality Control, Inspection & Packaging

Incoming, in-process, and final inspection of parts and assemblies against project drawings and acceptance criteria, including inspection records, nonconformity follow-up, and packaging suited to product sensitivity and transport conditions.

Scope

What this activity actually covers

The scope is written around the actual workflow rather than unsupported capacity or accuracy claims.

Quality control is meaningful only when acceptance criteria are clear. For each order, drawings, datasheets, purchase orders, ITPs, and explicitly referenced standards form the inspection basis. Measurement methods must match the characteristic and its tolerance range.

Dimensional inspection uses suitable equipment such as calipers, micrometers, dial indicators, and gauges as required. Calibration status is checked before use, and results are recorded for specified characteristics. Where nonconformities occur, NCRs and corrective records can become part of the project quality file.

Pressure, leak, NDT, or fluid-cleanliness checks are performed or coordinated only when included in project scope. Test pressure, hold time, NDT method, and acceptance limits come from the equipment specification or referenced standard, not from one universal figure for every product.

Core capabilities
  • Dimensional and visual inspection to drawings and acceptance criteria
  • Incoming, in-process, and final inspection as required
  • Nonconformity reporting and corrective follow-up
  • Pressure and leak testing to equipment-specific procedure and pressure
  • Coordination of project-required NDT using specified methods and qualified personnel
  • Protective packaging and sealing/capping of sensitive openings and surfaces
Deliverables
  • Inspection report or QC checklist
  • NCR and corrective-action records where nonconformity exists
  • Test or NDT report when required by the project
  • Relevant calibration records for measuring equipment when required
  • Packing list and accompanying shipment documentation
Workflow

From request to delivery

Project details vary, but the control and delivery logic generally follows this sequence.

01
Define acceptance criteria

Review drawings, datasheets, order requirements, and Hold/Witness points where an ITP exists.

Inspection method is defined before work starts
02
Dimensional & visual inspection

Check specified characteristics with suitable instruments and record accept, reject, or review status.

Results are compared with acceptance criteria
03
Additional testing

Pressure/leak tests, NDT, or fluid-cleanliness checks are performed or coordinated only when technically required.

Method and limits are taken from project requirements
04
Nonconformity control

Nonconformities are recorded and followed through technical disposition, correction, or customer approval.

Final nonconformity disposition remains traceable
05
Packing & release

Clean, protect surfaces/openings, package the item, and verify documents before dispatch.

Package and accompanying documents are reviewed before release
Typical applications
  • Machined parts and assembled equipment
  • Power packs, manifolds, and hydraulic-system components
  • Fabricated and welded assemblies
  • Incoming inspection of sourced goods
  • Parts sensitive to corrosion, impact, or contamination in transport

What to send for a faster technical review

The clearer the technical input at the start, the less back-and-forth is needed during sourcing, manufacturing, or inspection.

  • 01Drawing, datasheet, or purchase order defining acceptance criteria
  • 02ITP and Hold/Witness requirements where applicable
  • 03Pressure/leak/NDT method and limits where required
  • 04Packaging, preservation, and transport requirements
Send technical request

Start the project with the right technical information.

Send a drawing, part photo, part number, datasheet, or problem description so the requirement can be technically reviewed before quotation or manufacturing.

Hydraulic systems and fluid power

Quality control of hydraulic pumps, valves, manifolds and power units

Hydraulic equipment quality control should begin with defined acceptance criteria before purchasing or manufacturing. For hydraulic pumps, valves, cylinders, manifolds and power units, appearance is not enough. Product code, pressure and flow, mounting dimensions, material records, cleanliness, leak tightness and function must match the order.

Machined components require inspection of critical dimensions and internal passages. Welded reservoirs and skids require weld, distortion, leakage and coating checks. A useful report identifies the characteristic, method or instrument and the requirement used for acceptance.

Technical scope and related equipment

  • Nameplate, model, manufacturer, ports and accessories compared with the order
  • Hydraulic pump verification for pressure, flow and rotation
  • Hydraulic valve inspection for mounting, coil voltage and logic
  • Inspection of filters, motors, cylinders and accumulators
  • Review of material certificates, test reports and manufacturer documents

Engineering and selection considerations

  • Manifold inspection covers dimensions, threads, cavities, passage connections, burrs and internal cleanliness.
  • Cylinder inspection can cover stroke, alignment, rod condition, seal geometry, pressure and leakage.
  • Power-unit testing can include pump and motor assembly, rotation, oil level, filtration, relief setting, wiring, leakage, noise, temperature and circuit function.

Information required to begin

  • Drawings, purchase specifications and acceptance criteria
  • Inspection points, pressure range and test conditions
  • Material records, manufacturer reports and calibration status
  • Required output: checklist, photographs, report or non-conformance record
