Getting started in the die & mould sector
It is precisely these aspects that make MAPAL successful in sectors such as the automotive industry, machine engineering and the aerospace industry. Now the precision tool manufacturer is also offering efficient and economical solutions for the complete machining process in the die & mould sector. Versatile and precise high-performance tools and special tool holders with narrow contours and a precise radial run-out minimise polishing effort and reworking thanks to a constant surface finish in the milling process.

Acier et acier trempé
Les composants toujours plus complexes dotés de cavités et de nervures de renforcement de plus en plus profondes dans le cas du moulage par injection de pièces en plastique et du moulage sous pression obligent à utiliser des outils extra-longs présentant un diamètre en partie très réduit. Les géométries de pièce complexes et les différentes propriétés de matériau compliquent les tâches d'usinage et sollicitent fortement la résistance des outils.
Exemples d’applications :
- Moule plastique moulé par injection
- Moule sous pression
- Fonte

Pour les moules de présérie ou de prototype, il n'est pas rare d'employer des matériaux faciles à usiner. Des alliages d'aluminium ou de résine sont fréquemment utilisés. Les outils en carbure monobloc à coupe positive et polis, ou mieux encore les outils à insert PCD, garantissent alors une productivité renforcée et de courts temps d'usinage.
Exemples d’applications :
- Plaques de moulage
- Inserts de moules
- アルミニウム

プレ生産やプロトタイプの金型では、加工しやすい材料を使うことがよくあり、アルミ合金あるいはウリオル(プラスチック)がよく使われます。この場合、ポジ形状および部分的に研削した刃先を持つソリッドカーバイドツール、あるいはさらに優れたPCDツールが高い生産性と短い加工時間を保証します。
応用例:
- 前シリーズの金型
- 試作用金型
- 銅

放電加工用に電極を作るには、銅合金やグラファイト素材を加工する必要があります。製造する金型の要求に従って、電極材料を選択します。銅合金は比較的高価で、高い表面品質と形状精度が要求される仕上げ用電極に一般的に使用されます。マパールの特殊形状の超硬ソリッドエンドミルは、高精度の加工結果を保証します。
応用例:
- 放電加工用電極(EDMプロセス)
- グラファイト

グラファイト
グラファイトはツールに対して高い研磨効果を持ち、刃先に大きな磨耗を発生させます。磨耗が進行すると、加工するプロファイル形状が、崩れやすくなります。そのため、適切な形状のツールと最適な工具材質が必要となります。マパールではグラファイトの加工にダイヤモンドコーティングされたソリッドカーバイドツールやPCDツールを使用しています。

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.
