HOT STAMPING OF SCREWS AND BOLTS IN ALLOY STEEL, CARBON, IRON and STAINLESS STEEL
We produce UNI-DIN-ISO screws or custom design screws (special screws) by hot stamping through partial heating of the piece. Heating is carried out with an induction furnace or with an electric upsetting machine and subsequently, with the aid of system-made rockers and molds, we form all the required details

SANDBLASTING
Our Sandblasting plant with rubber carpet and grit (cylindrical / pyramidal) maximum load 500 kg.
Sandblasting is a mechanical process by which the most superficial part of a material is eroded through the abrasion caused by a jet of sand and air.
The use of this treatment consists in the surface cleaning of metals:
Remove scale before heating for stamping
Eliminate printing waste
testing
At the end of the processing cycle, each order is subjected to final checks that precede packaging.
The last check on the dimensions of the piece, the straightness, the threads, the hardness and every check that can guarantee the most correct and precise supply.
HRC hardness test with durometer.
Certified P/NP Thread Rings .
Calipers (even during production) .
Micrometers (also during production) .
