Graphite Die Casting for Aluminum and Zinc Parts

Graphite Mold Die Casting Die cast alloys with die casting properties are now possible without the time and expense of hard tooling. Graphite Die Casting delivers aluminum and zinc parts that are representative of those from a high-volume production run, which makes the process ideal for prototyping or short-run manufacturing.

Direct Electron Transfer Between Graphite Electrodes and

Electron transfer (ET) of ligninolytic peroxidases was studied in the bioelectrocatalytic reduction reaction of H2O2 at peroxidase‐modified graphite electrodes. Specifically, native lignin (LiP) and manganese (MnP) peroxidases secreted by Phanerochaete chrysosporium, as well as a few different recombinant MnP forms were used in the electrochemical studies. The recombinant enzymes included

Mikron HSM 500 Graphite High speed milling

Graphite machining has never been so attractive—and challenging. While graphite electrodes boost die-sinking electrical discharge machining's (EDM's) productivity and reduces costs, the graphite-based glass mold market is quickly growing, with new requirements in terms of surface finish, precision and machining speed.

Avenue to Large

Graphite electrode: Exfoliation was carried out for three different lab-grade graphite electrodes: graphite rod (GR), film (GF), and pencil (GP). During delamination, fine soft particles were dispersed into the solution in the case of GR, whereas particles in the form of small spun were released from GF.

Influence of the Molecular Weight of Poly‐Acrylic Acid

In this study Si‐alloy/graphite composite electrodes are manufactured using water‐soluble poly‐acrylic acid (PAA) binder of different molecular weights (250, 450 and 1250 kg mol −1). The study aims to assess the behavior of the different binders across all the steps needed for electrodes preparation and on their influence on the electrodes electrochemical behavior.
