Quality Management Team

‘Only the best quality is the way to survive.’

With a strong belief, we provide satisfaction and trust to our customers through continuous improvement and the best quality.

Quality Policy

We have set the following settings to aim for the best quality for customer satisfaction and never compromise on quality.

1. Best quality 2. Increased added value 3. Continuous improvement
4. Acquire advanced technology 5. Customer satisfaction

Quality Goals

To ensure implementation of the quality policy, quality goals are established and operated.

1. Zero process defects 2. Increased productivity 3. Stabilized quality
4. Cost reduction 5. Zero customer defects

Quality Management

In order to provide stable and reliable products, we place quality control capabilities at the core. Quality control plays a key role in ensuring that we maintain the highest level of quality at every stage of our products. We are in charge of quality management (QM), quality planning (QP), and project management (PM).

Quality Control

We focus on continuously improving product quality and maximizing customer satisfaction by establishing an efficient and effective quality management system. We ensure quality by systematically carrying out activities such as production, inspection, testing, and documentation. We are also responsible for quality control (QC), quality assurance (QA), and quality improvement (QI).

Precision measurement room

For more detailed manufacturing, we pay great attention to quality and pay a high level of attention to quality control, including having a separate measurement control room. Yeonhap System maintains strict standards for quality to always provide the best products to its customers.

  • Always keep clean

  • Periodically calibrate all measuring instruments in the measuring room

  • Soundproofing and dustproofing system applied

  • Temperature and humidity management according to standard room environmental standards

  • Temperature 20± 2℃ (1℃/hour), humidity 55%)

Quality Management

Yeonhap System maximizes customer satisfaction by providing the best quality and service to customers and pursues continuous growth and development.

Quality Assurance Activities

We implement a thorough quality assurance process to ensure quality at all stages, from product design to production and delivery. This includes incoming inspection, in-process inspection, shipping inspection, performance testing, and systematic analysis of customer feedback.

Quality Improvement Efforts

Quality improvement is our continuous goal. We conduct projects to improve products and processes through a systematic approach, such as the PDCA (Plan-Do-Review-Act) cycle. Every year, we form an HPT aimed at reducing COPQ and carry out improvement activities using the QC7 Tool.

Quality-related education and training

‘Excellent quality starts with excellent people.’ We construct a Skill Matrix to assess and visualize the various skills and competencies of individuals or teams within an organization. Through this, team leaders understand the current skill level of team members, identify training and development needs, provide regular training, and support team members’ competency development.

3D measuring instrument – (HERO7106S)

a major role

  • ​Periodic process inspection for mass-produced products

  • ​Final inspection of finished products

  • ​Check compatibility with other products

  • ​Various GD&T tolerance analysis

  • ​Extracting information needed for product development (Reverse Engineering)

Roundness measuring instrument – (RA-2200AS)

The measuring instrument is an advanced instrument capable of measuring key quality-related indicators such as straightness, roundness, cylindricity, parallelism, perpendicularity, coaxiality, circumferential runout, and total runout, ensuring high quality standards are maintained in our manufacturing processes. It is making a great contribution to

The RA-2200AS provides outstanding accuracy and reliability, ensuring superior performance in key measurement and quality control steps during product manufacturing. Through this, we strive to confirm the true quality of our products and improve production efficiency and minimize defect rates by detecting and taking action early on potential problems that may arise during the manufacturing process.

Micro Vickers Hardness Tester

Micro Vickers hardness tester is one of the instruments used to measure the hardness of materials. This instrument measures hardness by indenting the surface of a material using a diamond pyramid-shaped indenter.

  • Hardness measurement: Micro Vickers hardness tester can precisely measure the hardness of materials. Hardness is an indicator of how hard a material is and indicates the degree to which the material has strength.

  • Diamond Pyramid Tipping: Typically, the micro Vickers test uses a diamond pyramid to apply pressure to the surface of the material. This enables precise measurements.

  • Automation and data analysis: Provides automated functions and data analysis capabilities to help users work efficiently. This allows you to quickly analyze measured data and interpret results.

  • Response to a variety of specimen sizes: Designed to measure specimens of various sizes and shapes, allowing it to flexibly respond to a variety of applications.
