Agrati Group - Special Solutions - Electrification Small Icon

The electrification trend is shaping the future of mobility.
Following the evolution of the market, in recent years Agrati has pursued a development of products strongly focused on electrified vehicles.
Agrati has built expertise in creating bolts for electric vehicles, developing a dedicated design, consisting of long bolts and tie rods.
Agrati’s offer also includes the use of special materials for electronic applications due to their electrical conduction capabilities.
In other applications, electrical insulation requirements suggest the use of engineered plastics, which are part of Agrati’s knowledge and offer, also combined with cold forged metal parts.
In addition, electric vehicles require sealing properties for their bolts to ensure the safety of their battery pack, as well as the cleanliness of the products, to guarantee the control of particulate contamination and to maintain the correct operation of electronic & high voltage components.

APPLICATIONS

BATTERY PACK

Agrati produces special bolts for battery pack assembly, with structural, sealing and/or reinforcement properties to guarantee a safe and efficient battery pack functioning.
In particular, Agrati can also produce long bolts/screws for battery pack fixations, thanks to the investment in dedicated cold forging machines, made in steel or stainless steel, with a size range of M2 – M6 and a shank range of 100 – 600 mm.

Agrati has developed a cell-to-cell connection weldless solution, which allows:

  • Single cell replacement and recycling at cell level
  • Control of electrical contacts
  • Temperature and voltage monitoring
  • Cooling effectiveness
  • Ultra-fast charging
  • Automated mounting and dismounting

ELECTRIC MOTOR

Agrati even specializes in special screws, long bolts, and tie rods for electric motor assembly, as a result of its investment in dedicated cold forging machines, made in steel or stainless steel, with a size range of M2 – M6 and a shank range of 100 – 600 mm.

POWER ELECTRONICS

Agrati has developed fasteners with special features for power electronics, combining mechanical with insulating or conductive properties:

  • Self-tapping screws for metal sheets assembly. 
  • Touch-safe bolts obtained with the addition of polymers (these plastic and co-molded parts enable electrical insulation).
  • Busbars made with special copper alloys (i.e. CuCrZr), which guarantee high level of electrical conductivity.
