Products Process
The production of DIN 7995 Stainless Steel Spengler Screws with Sealing Discs involves several precise steps:
Material Selection: We utilize premium stainless steel (A2/A4 grade) for its excellent strength, corrosion resistance, and longevity in harsh environments.
Cold Heading: The stainless steel wire is cold-headed to form the screw's head and shank, ensuring structural integrity and enhancing strength.
Thread Rolling: The screws are threaded through a rolling process, which creates precise threads while work-hardening the material for added strength.
Sealing Disc Integration: A specially designed sealing disc is integrated into the screw during the manufacturing process, ensuring a secure seal that prevents moisture ingress.
Heat Treatment: The screws undergo controlled heat treatment to enhance their mechanical properties, increasing hardness and overall durability.
Surface Finishing: The screws are polished or passivated to provide a smooth finish, improving aesthetics and resistance to environmental factors.
Quality Control: Each batch is rigorously tested to ensure compliance with industry standards for performance, strength, and sealing effectiveness.
