Manufacturing Process

The production process of a self-drilling screw involves several stages. First, the raw materials - usually steel or stainless steel - are received and inspected for quality assurance. The materials are then cut to the required length and shape using specialized machinery.

Next, the screws are heat-treated to improve their strength and hardness. This process involves exposing the screws to high temperatures for a specific duration before cooling them down. The screws are then tested for their mechanical properties, such as their tensile strength and torsional strength.

The screws are then coated with various types of protective coatings, such as galvanized or zinc coatings, to prevent corrosion and rust. This is done using electroplating, hot-dip galvanizing or other coating methods. The screws are then passed to the assembly line where they are packaged and labeled according to customer specifications.

Finally, the self-drilling screws are subjected to quality control checks, which include inspection for defects, dimensions, and strength. This ensures that the final product meets the quality standards required by the customer before being shipped.
