Having a single point of contact, combining and pooling know-how, save time, securing production and quality, constantly seeking improvement, are all assets to meet the needs expressed by our customers and be the benchmark provider in finished products ready to assemble. Its mastery of both the forging and machining trades, technical expertise and the reliability of its processes make Walor the benchmark supplier of complete mechanical solutions in France and abroad.

Management of production units

Walor currently relies on 12 production sites.
They provide complementarity in terms of industrial resources and expertise, giving it complete control of all cold forging and machining solutions.
Its presence in 5 countries also generates a cultural diversity, dynamism and an international approach that are a source of Walor’s wealth.
The deployment of standard processes (‘1 part-1 process) makes it possible to offer the same level of Quality and Services in each of our factories. It thus offers a global solution to our customers located around the world.

Our technologies and areas of excellence

Forge

Cold forging (or cold extrusion, precision forging) consists of forming parts made of metallic material generally derived from a bar or wire rod. The high precision of the process in terms of dimensions and surface conditions, its sobriety as to the material used, the increase in mechanical characteristics and its high rates make it an efficient process. Semi-hot forging by heating, improves the forgeability of parts with the advantages of cold forging. The process however requires more complex means. Cold stamping, close to cold forging, differs by the use of very high speed horizontal presses. Walor’s strength is in mastering all these techniques, and has been providing European leadership in the automotive market for 50 years.

Free cutting

Free cutting is a machining technique that consists of manufacturing turning products by removing material from metal bars, using cutting tools on automatic of digitally controlled very high speed mechanical lathes. The parts are machined successively in a bar generally having the diameter closest to the outer diameter, the goal being to obtain the best productivity for high accuracy. Generally, the parts undergo subsequent operations (mechanical, thermal or chemical) before being used in the creation of subsets. Walor has been mastering these technologies for almost a century in the Arve Valley and in most of its other production sites.

Machining

Machining is a group of techniques for manufacturing parts by chip removal but from a blank made by another technology (sawing, forging, foundry, ..) and for shapes that can be more complex.
The means can be similar to free cutting, the machine tools used being mainly digitally controlled, but the parts are more complex to adapt to the shape of the blanks that must be machined.
Walor uses multiple material removal processes that can fall into this category: broaching, grinding, cutting, lapping, threading, drilling, tapping, … These operations can be complementary or integrated into the free cutting machines.

Inspections

Using appropriate procedures and means, inspections ensure that manufactured products, their components or process parameters, comply with internal specifications and customer requirements. Inspections are carried out at frequencies and sampling sizes defined according to statistical methods to ensure maximum safety. The checks carried out can be destructive (hardness, structure, test bench, etc.) or non-destructive (dimensional measurements, appearance, eddy currents, ultrasound, etc.). Most products manufactured by Walor are safety parts whose risk analyses lead to the implementation of the most efficient automated controls.

Heat treatment

A heat treatment is a succession of operations in which a solid material is wholly or partially subjected to thermal cycles to obtain a change in its properties (especially mechanical strength) and / or its structure.
They are used in Walor processes:

  • To improve the performance of products delivered to the customer (quenching, induction hardening, nitrocarburizing, nitration, …)
  • To allow or facilitate subsequent internal operations (deformation or machining) with the customer (annealing, recrystallization, spheroidizing, isothermal, …).

Tooling

In the fields of deformation and machining of metals, tooling is an essential component of the process. Walor controls the entire process of designing and producing tools. Specialized services manufacture the majority of the forging, machining and control tools, supported by our two centers of excellence – Walor Laval and Walor Saint-Pierre. Equipment used to produce these tools makes it possible to shape materials with ever more extreme properties.

Industrial excellence

We believe that the best way to sustain and develop our company is to give meaning to our business and to be very efficient when it comes to each plank of our strategy. In this context, Walor factories are the drivers of value creation. Efforts are coordinated and constantly renewed to ensure each site is in performance condition.

Proximity to our customers, whether external or internal, is cultivated, in order to better understand their expectations and needs, to find solutions for them and for their own customers.

In our eyes, improvement and excellence are possible only through teamwork, in the broadest sense of the term: extended to our customers and suppliers. Only by working as partners, in a win / win spirit, will we be better together.
