The furnace has a single, vertical, tubular heating zone which is integrated into the unit, giving a neat and compact design overall.

Ensuring high quality in the additive manufacturing process

Additive manufacturing, as well as powder injection molding, offer great potential if the raw materials employed are of optimum quality. But the process needs to be continuously monitored, and the finished parts need to be examined meticulously to ascertain the relevant parameters for a high-quality, cost-efficient production process.

Graphitisation at up to 3000 °C - What is it good for?

Graphite is a soft, slippery, greyish-black substance. It has a metallic luster and is opaque to light. Graphite is a good conductor of heat and electricity. Often graphite is simply named carbon. Under inert gas or vacuum graphite is extremely temperature-resistant which makes it an interesting material for high temperature applications.

Heat Treating 3D Additive Manufactured Parts

At present, there are two main techniques used in the additive manufacturing of 3D metal parts, Electron Beam Manufacturing (EBM) and Direct Metal Laser Sintering (DMLS). These take time but are outstanding for creating complex or ‘impossible’ parts which cannot be created using traditional casting or machining methodologies. This has already resulted in the creation of a multitude of prototype pieces as well as countless ‘impossible parts’ for the aerospace, automotive, tooling and medical sectors.

Heat treatment at low pressures

High temperature vacuum furnaces are used for heat treatment of samples at low pressure (down to 10-6 mbar) and under partial gas atmospheres. In the bottom loader version the bottom is lowered and driven out of the furnace. It then pivots forward to permit easy loading. This design makes the useable volume accessible from all sides and allows for exact placement of the sample thermocouples which measure the temperature of the sample.

High-quality materials ensure that the batteries can store and deliver energy reliably, while meticulous production processes guarantee consistency and safety.

Heat Treatment Solutions for Metal Injection Molding

The Metal Injection Molding (MIM) process is a widely known and applied technology for producing small metal parts. A great variety of materials and, consequently, approaches have been developed. The MIM process always requires a combination of polymer and metal powder. The polymer in this mixture has two purposes. On the one hand, it serves the rheological properties that are needed for injection molding. On the other hand, it provides the mechanical stability of the so-called green parts. The metal powder itself has no mechanical stability at all in that stage of the process.

How coke is created in a coal testing oven or pilot plant

Thanks to huge advances in metallurgy over the last three decades, 21st century steel production is transforming the globe and the built environment. Of course, a major part of the steel production process is the use of coke, which provides as much as 80% of the furnace's thermal requirements, the majority of the furnace's CO gas (which acts as a reducing reagent) and carbon for dissolution in the molten metal. As with any other manufacturing process, the quality of the raw material has a massive impact on the quality of the end product. It is therefore vital to ensure the coke is comprehensively tested.
