Quality

At Jinhan, our commitment to quality is the cornerstone of our operations. We understand that the reliability and durability of our products are paramount to our customers. Our Quality Control (QC) policy is designed to ensure that every piece of hardware, including our flagship Minifix connector, meets the highest standards of excellence. This policy outlines our comprehensive approach to quality control across various stages of production, from incoming materials to finished products, and details our full-process traceability system.

Incoming Material Quality Control

Objective: To ensure that all raw materials and components meet Jinhan's stringent quality requirements before entering the production process.

Methods and Strategies:
1. Supplier Qualification: We conduct rigorous assessments and audits of our suppliers to ensure they meet our quality standards.
2. Material Inspection: Upon arrival, all materials undergo a thorough inspection. This includes visual checks, dimensional measurements, and material property testing.
3. Sampling and Testing: Random samples are taken from each batch of materials for detailed analysis. For example, for Minifix connectors, we test the cold-rolled steel for composition and strength.

Goals:
- Ensure 100% compliance with material specifications.
- Identify and reject any substandard materials before they enter production.

In-Process Quality Control

Objective: To monitor and control the quality of products during the manufacturing process.

Methods and Strategies:
1. Process Monitoring: Continuous monitoring of production processes using statistical process control (SPC) techniques.
2. In-Line Inspections: Regular inspections at critical stages of production. For Minifix connectors, this includes checking thread precision, dimensional accuracy, and surface finish.
3. Operator Training: Ensuring all operators are well-trained in QC procedures and understand the importance of quality.

Goals:
- Detect and address any deviations in real-time.
- Maintain consistent product quality throughout the production run.

Finished Product Quality Control

Objective: To ensure that all finished products meet Jinhan's quality standards before shipment.

Methods and Strategies:
1. Final Inspection: A comprehensive inspection of finished products, including visual inspections, functional testing, and dimensional checks.
2. Batch Testing: Random sampling of finished products for detailed testing. For Minifix connectors, this includes load testing and corrosion resistance testing.
3. Packaging and Labeling: Ensuring that all products are correctly packaged and labeled, with clear identification for traceability.

Goals:
- Achieve a defect rate of less than 0.5% for finished products.
- Ensure customer satisfaction with every shipment.

Full-Process Quality Traceability System

Objective: To maintain a robust traceability system that tracks the quality of each product from raw material to finished product.

Methods and Strategies:
1. Data Recording: Detailed recording of all QC checks, including material inspections, in-process inspections, and final inspections.
2. Traceability Reports: Generating traceability reports for each batch of products, providing a complete history of the production and QC process.

Goals:
- Ensure full traceability for every product.
- Facilitate quick and effective response to any quality issues.

At Jinhan, our Quality Control Policy is designed to ensure that every product we manufacture meets the highest standards of quality and reliability. Through rigorous QC methods at each stage of production and a comprehensive traceability system, we are committed to delivering products that exceed our customers' expectations.
