THE WAREHOUSE

Our qualified pool of suppliers use only raw materials that are certified at the company and product level. Our strong relationships with our suppliers allow us to optimize stockage and meet every request in the shortest time possible. Quality control upon entry is carried out in compliance with the strictest standards, ensuring systematic monitoring of all supplies.

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) .

check

  • MT 100%
  • Traction and resilience
  • Ultrasound check (on starting material only on request in the offer phase)
