Quality Control & Testing Methods

Quality is measured — at every stage of the process

Our approach to quality control is based on precision measurements, strict compliance with industry standards, and multi-stage verification — from raw materials and in-process checks to final inspection of finished products.

We operate a dedicated testing lab, standardized procedures, and custom test tooling tailored to the electrical and mechanical specifications of each project.

We also accommodate customer-defined test protocols and can perform custom electrical or mechanical measurements on request. For injection-molded components, we offer detailed visual inspection focused on identifying material defects, inclusions, or surface voids.

Metrology Lab

We perform mechanical and electrical strength tests in accordance with ANSI/AAMI EC53, including pull tests using a Shimadzu tensile tester to evaluate connector retention force and conductor strength under load.

We also test the durability of cables and wires under mechanical stress, as well as the resilience of strain reliefs (cable boots) against bending and pull force — ensuring long-term performance under real-life use conditions.

In-Process Testing Tools

For custom projects, we design and build dedicated control and measurement fixtures, enabling on-line inspection of dimensions, crimp quality, electrical contact, and more — integrated into our production workflow.

We currently operate approximately 15 custom-built test tools, designed specifically for connector validation. Each tool allows us to connect the plug or socket directly to the test fixture and verify all electrical connections automatically, ensuring wiring accuracy and continuity before final assembly.

Multi-Stage Production Inspection

Our standard QA process includes:

  • resistance measurements (low-voltage continuity),

  • hi-pot (high-voltage insulation) testing,

  • visual inspection under a microscope,

  • full documentation and traceability — especially for OEM or regulated environments.

 

We perform in-process inspections depending on the complexity of the product and our internal quality data — particularly the historical scrap rates and typical failure modes observed during or after production.

Electrical measurements are conducted at multiple stages of every cable or wire harness production process to ensure ongoing compliance and integrity.

Visual inspection is typically performed at two critical stages:

  • during the injection molding process (e.g., to detect flash, voids or material inconsistencies),

  • and during final finishing operations, where we remove excess material, apply labels, install clips, and inspect molded strain reliefs or connectors.

Environmental & Climatic Testing

Our testing infrastructure includes:

  • climatic chambers for temperature cycling and humidity testing,

  • aging tests in heated or refrigerated environments,

  • simulations to assess long-term stability of cable performance under real-world conditions.

 

We currently operate an environmental test cabinet capable of maintaining low temperatures for cold testing, along with heating units (up to 70 °C) for accelerated aging, drying and material resistance validation.

Certifications & Compliance

Our quality system and products comply with:

  • ISO 13485 – quality management for medical device manufacturing,

  • ANSI/AAMI EC53 – standards for ECG and medical cable assemblies,

  • IPC-A-610 (Class 2) – acceptability for soldered joints and electronic assemblies.
