The METALLECA® Auto Accessories are generally manufactured by stamping, machining and bar processing.
To ensure shipment is no problems, our inspection is after the subsequent heat treatment and surface treatment, as well as a series of tests and verifications, such as corrosion of the coating, adhesion of the coating, torque of the thread, accuracy of the thread, mechanical properties, etc.
We will select appropriate materials, performance indicators, and surface treatment methods according to the different requirements and environments of individual equipment, or customers' needs.
Since each fastener products of specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods as well as the specific requirements for acceptance inspection, marking and packaging are separately stipulated in national (industry) standards. For example, British Standard (BS), German Standard (DIN), American Standard (ANSI), Japanese Standard (JIS), etc. |
