Our products implement the most stringent quality management system. There are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.
Vacuum packaging, the packaging quantity can be provided according to customer requirements and packaged separately.
Calcium selenide (CaSe) needs to be sealed and stored in a dry, inert gas protection environment (such as nitrogen or argon), avoiding contact with air, moisture and strong oxidants to prevent decomposition or performance degradation. The storage temperature should be controlled at room temperature, avoiding direct sunlight and high temperature environment.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
