Where is the overlay test going? BAIJIAN can provide coverage layer testing services, third-party, high-tech enterprises, CMA qualification certification institutions, complete testing instruments, strong scientific research teams, mainly engaged in industrial diagnosis, material composition testing, material quality testing, material performance testing and other services. Inspection reports can be issued within 7-15 working days, support scanning to check authenticity, and provide nationwide on-site sampling and sample sending testing services. The testing cycle is short, the testing cost is low, and the testing data is scientific and accurate
Test cycle: 7-15 working days
Test cost: Free initial inspection. After the initial inspection, a quotation will be provided based on the customer's testing needs and the complexity of the experiment.
Covering layer test scope: Automotive component covering layer, metal covering layer, enamel covering layer, rubber electroplating covering layer, anode and cathode covering layer, tire covering layer, mechanical surface covering layer, conveyor belt covering layer, steel wire covering layer, casting substrate covering layer, etc Covering layer test items: Salt spray test: Acetic acid salt spray test (ASS test), neutral salt spray test (NSS test), copper accelerated acetate spray test, etc Other: Vickers microhardness test, porosity test, wear test, full immersion corrosion test, impact test, hundred grid test, thickness test, adhesion test, shear wave test, failure analysis, etc If you have any other needs, please contact the laboratory engineer and we will provide you with one-on-one answers What are the functions of the BAIJIAN test report? What problems can I help you solve< p> 1. Sales use. (Selling one's own products and issuing third-party testing reports to make customers trust their product quality more)2. Industrial problem diagnosis and use. (When encountering some tricky problems, solve them by testing report data)
3. Improve product quality. (By comparing the testing data, identify the problems with one's own product, improve product quality, and reduce production costs)
4. Use of research paper data 5. Product import and export use. (Testing report from Baijian.com, supporting scanning code to distinguish authenticity!)
