Sealing

Pre-coating is an innovative and economic technology that replaces advantageously many sealing systems like gaskets, o-rings, sealing pastes, anaerobic resins, Téflon strips.

Our special machinery enable to realize small series (1000 units) as well as large series (1 million units) in a wide range of applications:

Sealing of the screw threads

Drain plug and smelter plug
Fitting to threads, straight or cone-shaped
Sensor plug
Metrical or self tapping screw thread screw or pin

Sealing of tubes and hafted units

Rigid nozzle and Pump outlet tube
Tight-hafted smooth cap

Underhead sealing on fasteners

Screw or plug socket
Blind nut and settable pin

We depose a resin on one of the unit to assemble in order to guarantee the assembly sealing. The resin fills the assembly and guarantees an immediate sealing during an assembly by screwing.

Many fluids will be sealed by the pre-coating technology:

Compressed air and gas
Drinkable water and warm water
Oils and hydrocarbons
Cooling fluids and brake fluids

The authorized pressure may go beyond the 50 bars, only for some assemblies.

Replaces expensive seals to be implemented
Replaces sealing products, fluid or pastes, and difficult to depose
Control of the technical parameters
Excellent quality: the presence of a sealing system is guaranteed
Vibration and shock absorption and noise reduction
Good resistance to chemicals
High admissible pressures
Seals many fluids
Immediate sealing after assembly
Important reduction of assembly costs in workshop or on a construction site.
