For castings subject to high stresses and with complex geometries, that is, with a high degree of freedom in design, a fine structure and good mechanical properties, it is not uncommon for permanent-mould-casting to be the first choice. As one of only a few tool makers, at KRÄMER+GREBE we are capable of meeting the widest range of requirements for all types of permanent-moulds. We are in the best position to offer the highest level of dimensional accuracy and optimal functionality for permanent-moulds in high-quality steel. We use our deep resources of experience and expertise to design and manufacture gravity and low-pressure moulds of all types with local deployment of special materials, high-performance cooling systems and local cooling, with temperature control and complex slider techniques, including in intelligent monocoque structures. Our moulds – with or without their own sand cores are based on ideal designs. The 100% shapable steel moulds meet both economic and functional requirements.

From design through engineering to production, we offer the entire process for high-pressure dies suitable for a wide variety of aluminium and magnesium castings. The modern equipment is also suitable for dies of the current trend in the field of mega and giga casting. Whether part of a powertrain or for large structural and chassis components, high quality, close tolerances and absolute precision are decisive for high-pressure dies. We will therefore support you from the development and design stages with filling and solidification simulations for the sprue and spillover positioning. This involves our modern equipment, such as the latest 5-axis simultaneous machining centres including workpiece and tool changers, which assures high-precision results. A spotting press or a chamber furnace for heat-treating the mould inserts and for the maintenance and repair service that also forms part of our services spectrum, complete our range of offerings.

KRÄMER+GREBE designs and manufactures patterns and core box tooling for small and large production series in various materials, complete with all technical casting and venting details. We offer complete tools for your core shooting machine suitable for all core production techniques. We produce individual, tailored tools to your exact requirements with all necessary accessories and to the highest standard of quality as core masks, for core package and green sand processes.

A focus at KRÄMER+GREBE is the development of extremely high-quality tools and complete model equipment. As a direct development partner, a team of our outstanding specialists designs and manufactures complete systems of equipment for foundry use. Complex casting concepts are developed in close exchange with customers and partners; simultaneous engineering harnesses synergies and saves time.

Tailored solutions for every tricky challenge: with each of the many demanding orders that it fulfils, the employees of KRÄMER+GREBE further deepen their area of specialisation. This knowledge is then applied systematically to ensure optimal production processes and perfectly suited complete solutions for handling, control, adjustment, mechanisation and automation.

A process newly developed and patented by KRÄMER+GREBE can be used in the following cases for better core-drying performance. Currently, casting foundries mainly employ the polyurethane cold-box process to manufacture cores while inorganic core-making processes are gaining popularity. During the cold-box process, the reaction and the accelerated curing of the core are set off through the addition of a catalyst mixed with a carrier medium.
