Quality Control According to ISO

Executive summary

An ISO-aligned approach to quality control replaces ad-hoc checks with a documented, risk-based system. We translate your drawings and specifications into control plans, sampling strategies, and acceptance criteria; verify with calibrated metrology; and preserve complete evidence for audits and customer files. The backbone is a process approach consistent with ISO 9001, extended for sector needs such as ISO 13485 for medical devices, AS9100 for aerospace, and IATF 16949 for automotive programs.

What “quality control according to ISO” means in practice

It starts with planning. Together we define special characteristics, measuring methods, tolerances, environmental and handling conditions, and release criteria. Sampling can follow ISO 2859-1 AQL where appropriate; safety-critical features are checked 100%. Measurement reliability is ensured through MSA and gauge R&R; equipment follows a calibration schedule traceable to ISO/IEC 17025 references. Results are analyzed with SPC and capability indices (Cp/Cpk) so variation is visible and controlled rather than guessed.

How BACH INDUSTRY AG implements it

Incoming goods are inspected against the latest controlled revision with ballooned drawings and control plans. Dimensional verification runs on calibrated gauges and CMM; functional testing is executed to your method when required, including torque, force, pressure/leak, and electrical checks. Nonconformities trigger immediate quarantine and an NCMR; corrective action is managed through SCAR and 8D with effectiveness verification. For first-article or program launches, we submit FAIR/FAI (AS9102) or PPAP evidence and lock lessons into the control plan so production remains stable.

Documentation and traceability

Every lot carries a digital traveler: measurement reports, photos, certificates of conformity/analysis, operator and equipment IDs, batch and serial capture, and release records tied to the exact drawing revision. Data flows to your ERP via EDI/API (SAP, Oracle, MS Dynamics, Infor) together with ASN, goods receipt, and quality postings. The result is clean genealogy and fast audit response without extra internal workload.

Standards and regulated sectors

Our system aligns to ISO 9001 for the quality management framework. Medical programs add ISO 13485 controls and device history expectations; aerospace programs align to AS9100 with AS9102 FAIR; automotive launches follow APQP/PPAP with IATF 16949 practices. Across all sectors we maintain REACH/RoHS compliance, preferential origin documentation, and controlled document management so specifications, procedures, and records stay synchronized.

Swiss QA meets customs-smart logistics

Quality control is embedded in a logistics stack designed for cross-border reliability. Goods can be held duty-paid or duty-free in our bonded (OZL) warehouse; we can kit, relabel, or perform light rework under customs supervision; duty and Swiss VAT are deferred until local release, or avoided on re-export. We handle customs clearance, HS classification, BTI support, and NCTS/T1 transit, then deliver on demand with a contractually guaranteed call-off within five working days. Standard components are available immediately from Swiss stock with no minimum order quantity.

Data, visibility, and improvement

Supplier performance is measured with the same rigor: OTIF, PPM/DPPM, lead-time stability, and CAPA burn-down are tracked on dashboards; trends drive supplier development plans rather than firefighting. Internally, we review capability data and nonconformance patterns to lower cost-to-serve over time while keeping your acceptance criteria intact.

Commercial model and regions

Engage per project or under framework and blanket orders with clear SLAs and KPIs. Pricing makes TCO visible by separating inspection effort, metrology, documentation, storage, freight, duties, and VAT in line with your Incoterms. We sell and ship with consistent price and lead-time logic across Switzerland, Germany, Austria, Liechtenstein, Belgium, and Africa.

What you can run through our gate

Multi-process parts and assemblies are routine: CNC machining and turning in aluminum 6061/7075, stainless 1.4301/1.4404, tool steels and copper alloys; sheet-metal and welded fabrications; injection-molded components in ABS, PC, PA6/66, POM, PEEK, and PTFE; castings, extrusions, and 3D-printed builds; electromechanical assemblies with line-side packaging. For each, we create ISO-aligned control plans, verification methods, and records you can defend in any audit.

Getting started

Send your drawings, BOM, and any sector requirements. We will propose a control plan and sampling strategy, confirm metrology and documentation, and return AI-backed pricing tied to a realistic delivery window. Production then launches with Swiss QA, bonded or duty-paid availability, and call-off exactly when you need it.
