Advanced hydraulic presses: excellence for self-clinching fasteners
Presses represent the most advanced technological solution for installing sheet metal inserts, commonly known as self-clinching fasteners. These components, essential in modern light metal fabrication, electronics (such as PCBs), and mechanics, are designed to create strong and durable joints on thin sheets and delicate materials where welding or direct threading is not feasible or cost-effective.
The principle of controlled deformation
The effectiveness of self-clinching inserts lies in the principle of controlled deformation. Installation occurs through the high pressure exerted by the press, which forces the insert head—typically knurled or hexagonal—to fit tightly with the sheet metal.
This process goes beyond a simple fit: the pressure locally deforms the material around the insert, mechanically locking it within the sheet thickness. The result is an extremely strong fastening, perfectly flush with the surface, ensuring optimal functional and aesthetic quality. The ideal machine for this operation is an automatic mechanical or hydraulic press.
The three pillars of the process: speed, safety, control
The use of specialized presses makes the installation process fast, safe, and precisely controlled, improving quality standards and reducing operating costs.
Fast: productivity and automation
Modern presses guarantee consistent, repeatable operations—essential for intensive production cycles. These machines can operate in two main modes:
• Manual: with direct and assisted loading of the insert by the operator.
• Automatic: advanced tooling, modular automatic feeding, and loaders allow multiple inserts to be handled in sequence or simultaneously, dramatically increasing installation speed.
Safe: operator and process protection
Safety is a top priority. Latest-generation machines are equipped with all necessary safety devices—such as sensors and protective barriers—to prevent accidents and ensure full operator protection throughout the entire cycle.
Controlled: precision and repeatability
What sets Technopartner’s professional presses apart is their electronic control capability. Through PLCs (Programmable Logic Controllers) and touch-screen panels, the operator can:
• Create and manage specific installation programs for each insert type.
• Set precise force and speed parameters.
• Configure and replicate work cycles, ensuring uniform results across all parts.
A key feature for precision is the Positive Stop system, which ensures greater fastening uniformity and reliability—especially when working on soft or delicate materials such as aluminum, fiberglass, or printed circuit boards.
