Démarrer dans la fabrication des moules et des matrices
Ce sont précisément ces aspects qui sont à la base de la popularité de MAPAL dans divers secteurs, dont l'industrie automobile, le génie mécanique et l'industrie aérospatiale. Il est donc logique que le fabricant d'outils de précision propose désormais des solutions efficaces et économiques pour l'usinage complet de moules et de matrices. Les outils haute performance précis et polyvalents ainsi que les porte-outils spéciaux avec contours fins et concentricité précise réduisent les opérations de polissage et le réusinage au minimum grâce à une qualité de surface constante lors du fraisage. Ils permettent de réaliser des économies substantielles tout au long du processus.

Steel and hardened steel
Parts that become more and more complex with increasingly deep cavities as well as moulded and reinforcement ribs in plastic injection moulds and pressure die casting moulds necessitate the use of extra long tools with diameters that can be very small. Complex part geometries and various material characteristics place the highest demands on machining and tool life.
Application examples:
- Plastic injection mould
- Pressure die casting mould
- Cast iron

Hierro fundido
En la construcción, la ingeniería y la fabricación de herramientas de conformado en frío de tamaño medio y grande se utiliza a menudo hierro fundido debido a las propiedades del material, tales como la resistencia a la presión y la fácil maquinabilidad. En este caso, los componentes principales son las placas de molde y los insertos de molde. MAPAL tiene una gran experiencia en el fresado (2D y 3D) y taladrado (taladrado, escariado, roscado).
Ejemplos de aplicación:
- Placas de molde
- Insertos de molde
- Aluminio

Aluminio
Cuando se trata de moldes de series piloto o de prototipos, no es raro que se utilicen materiales fáciles de mecanizar. A menudo se emplean aleaciones de aluminio o ureol (plásticos). En estos casos, las herramientas de metal duro con filos de cuchillas positivas y parcialmente pulidas y las herramientas de PCD aún mejor procuran una elevada productividad y breves tiempos de mecanizado.
Ejemplos de aplicación:
- Moldes de serie previa
- Moldes de prototipos
- Cobre

Cobre
La fabricación de electrodos para procesos de gestión de datos energéticos requiere mecanizar aleaciones de cobre y materiales de grafito. La elección del material de los electrodos se rige por los requisitos del molde que se debe fabricar. Las aleaciones de cobre son relativamente caras y, en general, se utilizan para el mecanizado final en los electrodos cuando se trata de una elevada calidad de superficie y precisión de moldeo. Las fresas de metal duro con geometrías especiales de MAPAL garantizan aquí unos resultados de mecanizado muy precisos.
Ejemplo de aplicación:
- Electrodos para electroerosión (procesos EDM)
- Grafito
-
Grafito
El grafito tiene un efecto muy abrasivo sobre la herramienta y genera un gran desgaste en el filo de la cuchilla. El aumento del desgaste tiende a reventar los perfiles que se mecanizan. Por esta razón se requiere una herramienta con la geometría adecuada y el material de corte óptimo. Para el mecanizado de grafito MAPAL utiliza herramientas de metal duro con recubrimiento de diamante o herramientas de PCD.
Ejemplo de aplicación:
- Electrodos para electroerosión (procesos EDM)

2D surfaces
On the one hand, this category includes machining processes carried out directly on the machine, such as face milling, milling of pockets and straight walls. On the other hand, it also includes operations for complex geometries that are programmed using CAM software.

3D surfaces
In the die & mould sector, the manufacture of increasingly complex forms is part of everyday life. Continuous further developments in machine tools and CAM software raise performance and productivity to an ever higher level. The tools used must therefore always be state-of-the-art. To achieve optimum results, each design starts with a process analysis.

Open pockets
Mould inserts also have machining tasks that are required for casting or various attachment parts. Users are increasingly machining open pockets (circumferential machining) using trochoidal milling. This machining method helps to optimise machining times and to extend tool life.

4 / 8
Closed pockets
Closed pockets are usually produced by roughing in Z planes. When milling, a ramp is often selected as the machining entry. The tool selected depends on the depth of the walls and the mould incline to be generated on the component. MAPAL’s broad portfolio with modular systems also covers the machining of deep pockets with large diameters.

Helix milling
A major focus in milling operations is on reducing the machining time. With specific tool geometries for machining closed, round pockets, it is often possible to eliminate the pre-drilling process. With helix milling, milling paths are programmed with helical entrances that are suitable for pocket dimensions.

Even surfaces
Operations to create even surfaces occur very frequently and in different areas in the die & mould sector: It could be component-related, strategy-related due to the respective milling process or due to requirements for mould closing surfaces as well as sections and cutting dies. The right tool is then selected depending on the application and requirements.

Thin walls and ribs
Plastic injection moulds and die casting moulds often have ribs and thin walls. Ribs, for example, are increasingly being milled, as this process is more cost-effective than EDM (spark eroding). As a rule, long or extra-long carbide tools with small diameters are used. Customer-specific solutions (RibCutter) to match the respective rib shape are also possible here.

Small and large bores
There is a wide range of full bore operations in the die & mould sector: From large bores for guide pillars and deep bores for the cooling system to high-precision bores for ejector pins. MAPAL offers a comprehensive portfolio of drilling and reaming tools for the individual production steps.
