Thread size 14mm automotive spark plugs  M5427-3-CNG

NINGBO MARSHAL AUTO PARTS CO., LTD. is a professional Thread size 14mm automotive spark plugs  M5427-3-CNG Suppliers and Thread size 14mm automotive spark plugs  M5427-3-CNG Company, The company has a variety of product lines, engineering and technical capabilities, and manufacturing capabilities are in constant progress. Regarding engineering skills,30 years of development and reverse engineering experience. The electrode has PASS TUV, CONFORM TO RoHs & Reach. High-strength insulators use a 360°Continuous Laser technology. In manufacturing, it also has a ceramic factory, ceramic Insulators are completely self-produced, with a high density of insulators, better dielectric strength, thickened design of insulator nose, and better mechanical strength which can satisfy modern engines well. Secondly, electrodes have electrical conductivity, heat resistance, heat dissipation, and ablation resistance. Shells have better malleability, better toughness, and higher hardness which can reduce shell breaking and help the shell for better heat dissipation. Regarding experimental capacity, the laboratory fully complies with and strictly implements 17 international and national spark plug industry test standards; enterprise internal control standards of more than 34 original supporting level tests; and process inspection coverage of the whole process of control points. Quality management has obtained the quality management system certification. Company for some spark plugs and design patent certificate, utility model patent certificate.
