Șuruburi formatoare de filet din piese prelucrate – înșurubare directă
Thread forming screws manufactured from turned parts – direct screwing - The economic adjustment to small batch sizes, we meet with our turned parts for the direct assembly in plastics and die-cast products. Any thread forms such as, thread-tapping (DIN7500), thread cutting (DIN 7513-7516) or KTG for direct screw in plastics are realized cost-effectively.
Advantage is the elimination of high tooling costs, since no counter-thread in the workpiece (eg threaded inserts, nuts, etc.) is required because the direct assembly takes place directly into the workpiece. Only a given tube is required in order to screw it directly.
Our turned parts replace previously cold formed parts used (so-called multi-station presses) which require high output volumes in order to achieve a reasonable price parts.
