ISB guarantees the requirements of its products by implementing a systemic approach based on management systems. In particular, the schemes currently in use are based on the ISO9001, IATF16949 and ISO14001 standards.

These systems, combined with specialised tools such as PFMEA, APQP, MSA, SPC, PPAP, make it possible to approach the product from the feasibility phase to after-sales service according to predetermined schemes aimed at maximising the Quality of the components and services provided. The use of FIFO, full traceability and KPI monitoring are in daily use and strongly rooted in company dynamics.

Quality Assurance and Control

Quality Assurance deals with management systems and their implementation, as well as new product approvals and complaint management, while Quality Control constantly monitors product manufacturing from the initial approval stage to the final pre-shipment decision.

Certifications and attestations

ISB is an IATF 16949:2016 – UNI EN ISO 9001:2015 – UNI EN ISO 14001:2015 certified company.

Life Fatigue Test

The test is performed with mechanical machines capable of replicating the life of compression and extension springs.

The test frequency is adjustable up to over 10Hz and this allows – if the spring geometry and expected arrow allow it – to perform accelerated cyclic tests (e.g. 10^6 in less than 24h) assessing whether or not the spring will resist during its normal service life.

The test is conducted both at the design/co-design stage to fine-tune the component and at the product approval stage to verify the goodness of the design and for the approval of each individual batch as needed.

100% Sourcing

The 100% selection is made for two reasons:

  • cutting process queues where the requirements expressed by customers are stricter than the natural tolerances of the production processes,
  • elimination of macro-defects in order to align our products with customer requests.

The machines used are equipped with automated feeding systems (vibrating cups with singulators, anthropomorphic robots, etc.) and are mainly based on load cell or camera systems.

Before being discarded, the NC parts are isolated and analysed, as well as the data collected in the sorting machine software.

Failure analisys – SEM

Failure analysis using scanning electron microscopes (SEM) is essential for investigating the failure mechanisms of components and discovering the causes.

The analyses carried out can be both morphological (the fracture surface is studied at high magnifications) and “chemical” (using an EDS probe) in order to search for indicators that can highlight both the type of fracture, e.g. fatigue, ductile, brittle, and the triggers that led to it, e.g. notches, non-metallic inclusions, surface defects, etc.

Each analysis is accompanied by a report including initial assessments, SEM images and conclusions.
