Products Inspection

The product quality inspection of our company is based on the manufacturing course of the products, including raw materials inspection when purchasing, semi-finished products inspection control, and the final inspection of the finished products. The raw materials inspection must be finished within 24 hours after purchasing, issuing a "detecting and testing report". Only after the qualified test, are the materials allowed to be stored in the warehouse; otherwise the raw materials will not be accepted or be part of the production procedure.

We use the method of composition inspection and spectrometry analysis to inspect and control the quality of our semi-finished and finished products. We use specialized vocational methods for round ingot quality, squeeze quality, finished-products quality and patrol inspections to guarantee each course of the manufacture. We establish key quality control points in each course of the product realization to guarantee there is no negligence.

Fenglu uses the most advanced and complete product inspection equipment among the aluminum products enterprises of China. These include direct-reading spectrometers, 100 kN microelectronics universal rally testing machine, salt spray testing box, computer gloss meters, 50×-1500× metallurgical microscope, Q-SUN xenon light testing box, Luomi products testing system,10-5000nm ultrasonic flaw detectors, vicat softening point/heat deflection test apparatus, Baerhuoke indentation experimental instrument, spectrophotometry color measurement instrument etc.

Quality Control

"International Quality, Fenglu Aluminum Products" is the fundamental criteria.
Our company insists on "Quality is Life of Enterprise" as our quality control principle. We have built up an orderly quality management system, passed many international standard management systems and product quality certifications, such as ISO9001:2000, ISO14001:2004, OHSAS18001:1999, DNV of Norway, military industry quality system of China, etc. We are one of the first companies to receive Products Exemption from quality surveillance inspection in China. We have received "Adopting International Standard Products Certificate", the "Famous Products of Guangdong Province Guangdong Famous Trade Mark", the "Famous Trademark of China", and the "Famous Products of China".

Our company strictly practices the quality inspection rule "do not use non-qualified raw materials, do not manufacture non-qualified products, and do not send out non-qualified products". We believe in the quality monitoring principle of "letter course detect former course, self detection combines with quality detection monitoring". At our quality inspection center, we inspect from beginning to end, ensuring high quality and long term stability. We have 320 employees working in quality control and are training 15 people who have obtained the qualification of national quality control. We are setting up 450 "after-sales" service stations and offer free hotline service.

Quality is Character. The feature of us is "Quality is most stable Product is best, Handing out fastest", we have won a top place in the competed market.

We believe quality is character. By featuring "Our most stable product is our best quality", we have won a top place in the competing market.
