At Haomaer, Quality Control is the core of our production and service, and we regard it as the foundation of long-term cooperation with customers. Quality Control (QC) runs through the entire production process, from raw material incoming to finished product delivery, to ensure that every precision part meets the set standards. We are equipped with professional inspection equipment and a professional quality inspection team, adhering to the principle of “zero defects” to provide customers with reliable and high-quality products. All our operations comply with ISO 9001 quality management system and RoHS environmental standards, and we have complete quality traceability system to ensure the consistency and stability of product quality.
Professional Inspection Equipment
We are equipped with a full set of high-precision inspection equipment and a professional quality inspection team to provide comprehensive quality control support for our products. The main inspection equipment includes:
Coordinate Measuring Machine (CMM): Used for high-precision dimension detection of precision parts, with an error range of ±0.005mm, which can accurately measure the geometric dimensions, surface roughness and other key indicators of the parts, ensuring the accuracy of product size.
Vision Measuring Instrument: It is used to detect the surface finish, edge smoothness and structural integrity of parts, and record the inspection data in real time to ensure the consistency of each batch of products.
Hardness Tester: Used to detect the hardness of parts, match the material performance requirements, and ensure that the parts can meet the application needs of different scenarios such as automotive and medical.
Surface Roughness Tester: It is used to detect the surface finish of parts, avoid surface defects such as burrs and scratches, and ensure the surface quality of products.
Strict Quality Inspection Process
We have established a complete quality inspection process, covering every link from raw material incoming to finished product delivery, to ensure that every product meets the quality standards:
Raw Material Inspection
For the raw materials entering the factory, we will conduct strict incoming inspection, verify the material composition and performance through professional testing equipment, and only the qualified raw materials can enter the production link.
First Article Inspection
Before mass production, we will conduct a full inspection of the first article of the product, confirm the dimensional accuracy, surface quality and other indicators, and start mass production only after passing the inspection.
In-process Inspection
During the production process, we conduct random sampling inspection on the products, increase the sampling frequency for key processes, and timely find and solve the quality hidden dangers.
Finished Product Inspection
After the production of finished products, we will conduct a full inspection of each batch of products, including dimensional accuracy, surface finish, material compliance and other indicators, and issue a complete inspection report.
Pre-shipment Recheck
Before the products are shipped, we will conduct a final recheck to ensure that the products are qualified and the inspection data is complete, so as to avoid unqualified products being delivered to customers.
Precision Tolerance Capability
Our quality control team has rich experience in precision inspection, and can achieve strict control over the precision of parts. The specific precision capabilities are as follows:
- Tolerance Control: The maximum tolerance can reach ±0.005mm, which fully meets the precision requirements of high-precision parts such as automotive, medical and aerospace fields.
- Surface Quality Inspection: We strictly check the surface of parts, avoid scratches, burrs, oxidation and other defects, and ensure that the surface finish meets the customer’s requirements.
- Material Verification: Through professional testing equipment, we verify the material composition of parts to ensure that the material meets the set standards and avoid quality problems caused by unqualified materials.
- Data Traceability: All inspection data, including raw material inspection records, production process inspection records and finished product inspection reports, are fully recorded and can be traced at any time to ensure the transparency and authenticity of quality.
Certification & Quality Guarantee
ISO 9001 Quality Management System: Our factory has passed the ISO 9001 quality management system certification, and all production and inspection links comply with international standards to ensure the stability and consistency of product quality.
RoHS Compliance: All products and raw materials comply with RoHS environmental standards, without harmful substances, and meet the environmental protection requirements of international markets.
Quality Traceability System: We establish a complete quality traceability system, from raw material incoming to finished product delivery, every link is recorded in detail, which can be traced and inquired at any time.
After-sales Quality Guarantee: If the product has quality problems due to our reasons, we will provide free rework, replacement or other solutions in a timely manner to ensure the legitimate rights and interests of customers.
