New Materials with Traditional Casting Technologies

IT COULDN’T BE EASIER!

 

Welcome to CMMC GmbH - the innovator in the traditional foundry business. Ubiquitous demands for lightweight construction alongside energy and resource efficiency while exhibiting good application properties quickly stretch conventional materials to their limits. The solution is to use composite materials, e.g. aluminium matrix composites (AMC), which combine the strengths of disparate materials. However, the application of AMCs in the broader sphere has been hindered by the currently still-complex manufacturing processes and thus limited availability. CMMC GmbH is taking action to change that! With our novel, patented casting technology, we are taking AMC materials out of the niche and into broad application.

Global Trends and Challenges

CO2 Reduction

By using innovative AMC lightweight materials, you can significantly reduce the energy consumption of vehicles. Rotating or unsprung masses, as used in braking systems for example, are greatly decreased, allowing for the significant reduction in exhaust emissions.

Energy-Efficient Production

Casting of steel and aluminium alloys is responsible for around six percent of global CO2 emissions. In comparison to that of conventional materials, however, in our case, the production of AMCs results in far fewer CO2 emissions due to the continuous process control and process chain combination.

Sustainability

Highly stressed components last longer, so AMC components have a longer life cycle. AMC composites are characterised by their high resilience and are able to be recycled. Furthermore, components can be remelted at any time and returned to the production cycle.

Local Production

All semi-finished products and ingots of AMCs we offer are produced exclusively here in Germany. At every point in the value chain, we only use locally available raw materials. In this way, we guarantee you a stable supply chain and reliable adherence to delivery dates. 

Our Services

Lightweight Materials for Serial Production

Ingots & Bars

Use our standardised ingots to melt AMC material and cast it into your mould components.

Particle Injection

Together with you, we develop semi-finished products for a wide range of forming, machining, and processing operations. We will also manufacture your semi-finished products as near-net-shape blanks.

Further Processing R&D

We support you in finding and developing suitable AMC compositions for your specific application.

Energy Transformation made easy – Advantages of AMC

  • Serial Production

    The AMCs were previously produced through  inefficient powder metallurgical processes. However, these did not allow for an industrial solution. With our process, we provide you homogeneous material for high-quality components on an industrial scale.

  • Great Functional Properties

    Through the targeted combination of metallic matrix and reinforcement particles, we adjust the AMC material to the desired tribological, mechanical, and/or thermal properties. In this way, you implement the slim design features of lightweight construction even for highly stressed components.

  • Energy-saving Potentials due to Lightweight Construction Applications

    With AMC lightweight materials, you can combine high economic potential with efficient resource protection. Due to the weight reductions in moving masses, the energy input is significantly reduced.

  • Recycling of the Metal Component

    As part of the crucible melt extraction process, we separate the metallic portion of the material from the non-metal phase. Subsequently, we return the aluminium to the production process as part of a closed-loop economy.

  • Customised Order Processing

    A CMMC employee is personally at your side for the entire order. We support you from initial inquiry to the development of the right material for your specific application, offering you a one-stop solution.

Cooperation with CMMC

NOTHING EASIER

Aluminium matrix composites consist of a coherent metal matrix into which we inject ceramic particles. The result is a light metal composite material whose properties can be tailored to each specific application. With a low material density, adjustable thermal conductivity, and low thermal expansion, properties are achieved that cannot be reached with conventional single-component aluminium alloys. However, there was still a problem - there was no efficient process was available to produce AMCs on an industrial scale. That is, until now. Now we have developed and patented a process to provide the material in demand on a large series scale for your applications.
