DG Vifort Precision Manufacturing Ltd. has successfully renewed its ISO 9001:2015 (Quality) and ISO 14001:2015 (Environmental) management system certifications following recent surveillance audits. The certificates, issued by Beijing Zhong An Zhi Huan Certification Center, are valid from December 2024 to December 2027. This achievement reaffirms our commitment to delivering high-quality precision hardware while adhering to rigorous environmental standards and sustainable operational practices.

DG VIFORT's technical guide details 15 precision fastener surface treatments, focusing on performance, cost, and reliability for industrial electronics. It provides critical selection data on anti-corrosion (Zinc-Nickel, Dacromet), electrical function (Silver, Nickel, Tin), mechanical hardness (Nitriding/QPQ), and dimensional precision (Electroless Nickel). The guide helps engineers match the optimal coating to extreme environments, high-current, and strict dimensional needs.

Vifort transforms custom and non-standard nut production from machining to cold forging, achieving higher efficiency, lower costs, and stronger performance for large-scale manufacturing.

Screws made of 6061-T6 aluminum alloy are widely used in aerospace, automotive, marine, sports equipment, and electronics industries due to their high strength, lightweight, and excellent corrosion resistance. As a factory manufacturer, we specialize in custom production according to customer drawings and samples, with options for anodizing, surface finishing, and bulk supply.
