From design to serial production of your parts
Co-Design and Development
1
In close collaboration with the engineers of the LGC design office, you will define the specifications, technical requirements and constraints of the project.
- Feasibility control using the FMEA tool, which is used to analyze failure modes, their effects and their criticality.
Prototyping and Testing
2
Once the concept is approved, the project team creates physical prototypes using a 3D machine and simulation software such as SolidWorks Premium, Spacerclaim.
- Manufacture of initial samples in medium series, and validation of production with PPAP according to the IATF 16949 standard.
Industrialization and Production
3
The serial transition is carried out according to the validated process according to the production control plan written by a multidisciplinary team.
- Development of detailed production processes according to the APQP quality process
Assessment and Improvement
4
After 3 to 6 months of series production, an evaluation based on the criteria required by the IATF 16949 standard verifies the conformity of the project at 100%.
- Collection and analysis of production data to identify trends and variations. 3PPM in 2023.

The threaded socket: assembly and fixing in one piece
Threaded sockets are essential elements in ensuring a solid and durable attachment of your parts. Thanks to their cylindrical design with an internal thread, they offer excellent pull-out resistance.
You can screw and unscrew them at will, which makes it much easier to assemble and disassemble your assemblies.
At LGC, we understand the importance of designing tailor-made solutions to meet your specific needs. This is why we support you throughout the process, offering prototyping, measurement and pull-out services. In addition, our expertise allows us to help you industrialize your project by offering you effective installation and assembly solutions.
How is an LGC threaded socket made?
From the material to the threaded socket
The manufacturing process for threaded sockets begins with steps similar to those of threaded inserts and self-tapping sockets.
The first step is to prepare the raw material coil.
Then, the part is deformed when cold, which improves the elastic strength of the material.
The second step is to cut the raw material tube in a suitable machine.
The tube is cut to the desired length. It is possible to add chamfers or finishes to the material.
Then, the part goes through a grinding stage. A roller presses the parts against a grinding wheel rotating at high speed. It is thanks to the abrasion of the grinding wheel that the diameter of the part is modified to reach tolerances of a few microns (~5-6 μm).
Finally, make way for tapping! A rotating tap will pass inside the part to give it the appropriate internal thread.
What are the advantages of a threaded socket?
- Reinforcement in soft materials: the threaded socket reinforces fasteners in soft materials, offering increased strength for fasteners with screws and bolts. This is particularly useful in assemblies subject to significant loads.
- Increased lifespan: thanks to its ability to provide a stronger thread, the threaded socket extends the life of the assembly by minimizing the wear of the thread over time.
- Reduced risk of tearing: these spacers reduce the risk of taps being pulled out, ensuring stable fastening even under conditions where loads may vary.
- Ease of repair: In the event of damaged tapping, a tapped socket provides an effective repair option, eliminating the need to replace expensive components.
- Application in demanding environments: the threaded socket withstands demanding environments well, offering a reliable solution even in conditions where other fastening methods could fail.
