Tools
Tooling, SEMO's historic business
introduction
As its original name, Saint Eloi Mécanique Outillage, suggests, SEMO built its current business by starting with the design and manufacture of precision mechanical tools, mainly form tools. This expertise has been strengthened with cylindrical tools and multiple special tools.
SEMO has acquired engineering, production and development skills, as well as the associated production resources (electrical discharge machining, grinding, etc.).
Cylindrical tools
Cylindrical tools enable components to be cut from rolls of flexible material: paper, cardboard, synthetic materials, etc. The cylinders can be cut from solid material or be magnetic so that a cutting plate can be attached to them. Cylindrical cutting allows very high speeds to be achieved (several hundred products per minute). SEMO has mastered the keys to successful cutting cylinder integration: control of the forces to be applied, ejection systems for cut parts, concepts for quick cylinder change, etc.
Tools to follow
The follow-up tool (also known as a progressive tool) allows successive operations to be performed on the same metal strip in a single press stroke. These operations may include cutting, bending or folding. This reliable solution allows high production rates (several dozen parts per minute, or even one part per second) even for complex parts, and guarantees a high level of precision and quality.
Assembly tools
SEMO has developed significant expertise in the tools required for assembly operations. For example, SEMO develops and manufactures press-fit tools. The upper press-fit tools align the connector and its pins with the PCB, while the lower press-fit tools absorb the pressure exerted by the press under the products.
SEMO also supplies crimping tools that bend the tabs of one metal part onto another to create a connection, ensuring a satisfactory bond. Finally, SEMO supplies riveting tools that position two parts to be assembled, one against the other, and absorb the forces applied during the riveting process.
