Process Inside.
Performance Outside.
At LITMAT we manage the entire process in-house.
From raw material to packaging.
Raw materials
Quality has tangible roots.
We work with steel, brass and aluminium, using drawn bar or wire, and we devote constant attention to the selection of suppliers and materials to ensure strength, durability and high performance.

Turning
One of LITMAT’s operational cores: bar turning on automatic lathes, multi-spindle CNC and single-spindle CNC machines, with machining capacity from 8 to 80 mm in diameter.
Multi-spindle machines ensure high productivity, while CNC lathes provide flexibility for medium and small batches, as well as the possibility to produce custom samples.
Our machining processes are robust, delivering precision, reliability and the ability to create complex geometries.
Cold forming
A cornerstone of LITMAT’s production: cold forming on multi-station horizontal presses, equipped with load sensors and precise control of processing parameters to ensure tight tolerances, uniform parts and consistent long-term performance.

Secondary Turning
The semi-finished parts obtained through cold forming can undergo a second operation on dedicated lathes to complete their geometry.
With this production cycle, we can offer large-series plugs with more complex shapes at competitive prices.
Thread rolling
Three-roller thread rolling ensures gradual deformation and perfect thread roundness.
On the same machines we can re-roll the plugs after surface treatment to restore the thread and guarantee proper screwability during assembly.

Washing
A crucial step for an excellent final result: vacuum washing in a closed chamber, which effectively removes machining oils and ensures fast drying to guarantee proper adhesion of the surface treatment.
As parts exit the washing chamber, anti-rust protectives and lubricants are applied, providing corrosion resistance and a stable, controlled friction coefficient for optimal screwability during assembly.
On a dedicated washing machine, we also perform cleaning cycles with controlled cleanliness levels and verification of residual particulate.
Special processes
Magnet assembly
We assemble magnets using dedicated vertical presses. The process ensures precise insertion of the magnet into the metal body and strong fastening without the use of adhesives.
If required, the magnet can also be bonded using two-component epoxy adhesives.
Laser marking
Custom laser marking on metal components to ensure traceability and permanent identification.
The process is contactless and does not alter the mechanical properties of the part, providing a clean, indelible and highly precise engraving, even on treated or small surfaces.
Sealant application
We apply sealants to the threads to ensure component sealing in service and to prevent leaks or seepage.
Sealants are automatically and precisely dispensed, tailored to the material and application, ensuring uniform adhesion, vibration resistance and long-term corrosion protection during assembly and operation.
Automatic selection
We use optical sorting machines for 100% dimensional and visual inspection. The components are analysed by high-resolution cameras to verify tolerances, surface integrity and geometric accuracy. The system automatically rejects non-conforming parts, ensuring consistent quality, full traceability of inspections and reliable finished products,
even at high volumes.
Packaging
At LITMAT, packaging is also a fully in-house phase, carried out with care and with selected materials to ensure proper preservation and customization of every batch.
Custom packaging and labels are the final step in enhancing the full value of our product quality.
Warehouse and logistics
optimized, advanced and efficient
For a company supplying major automotive manufacturers, warehouse and logistics management is a decisive factor.
Having an in-house warehouse with automated racking ensures better product preservation and optimized space usage.
We manage EDI flows: automation minimizes the risk of human error, streamlines order preparation times and ensures maximum reliability of deliveries.
This way, our customers’ production lines run without interruption, and service quality remains consistent even with high volumes or sudden urgent requests.
