Graphite Ingot Molds for Precious Metal Casting

Precious metal molds, including graphite ingot molds, are in high demand lately. Gold and silver are traded in international markets as bars or ingots, and the process of precious metal casting requires a mold in which to pour the molten metal. Graphite ingot molds are the preferred choice for most gold and silver refiners in the USA. Semco is proud to be one of the leading suppliers of these precious metal molds. Why Graphite is Great for Precious Metal Molds Graphite ingot molds are made from high-density graphite, which has excellent thermal stability and can withstand high temperatures. Graphite is also...

Carbon and Graphite

In today's fast-paced world of manufacturing, the need for high-quality materials that can withstand extreme conditions, such as carbon and graphite, is becoming increasingly important. Graphite is an allotrope of carbon and thus shares characteristics with it. Both carbon and graphite have become essential in many industries, including aerospace, automotive, and electronics. While both materials are made up of carbon, they have different properties that make them suitable for different applications. The graphene structure of graphite, in particular, gives this material qualities that are sought out by many industries. How Carbon Becomes Graphite Carbon is typically depicted as an irregular,...

How Synthetic Graphite is Made

Why Synthetic Graphite and not Natural Graphite? At Semco, we love natural graphite. It’s the OG, the original. There’s just one problem: there isn’t enough of it. Synthetic graphite has to step in to fill the need. As it turns out, synthetic graphite is actually preferable to natural graphite in many ways. And while Semco doesn’t make its own graphite (we have industry partners that do that), we love knowing how it’s made. Knowing synthetic graphite material inside and out means knowing what’s in it and how it’s made (extrusion, die molding,, etc). Allow the synthetic graphite experts at Semco...

Computer Aided Design, or CAD

Computer-aided design, more commonly known as CAD, is the use of computers in the design process across a wide range of industries. CAD software is primarily used to create highly accurate models, but CAD covers all steps in the design process, from creation and modification to analysis and design. In our industry, CAD software is notably used to create precise drawings and models of objects and structures. CAD was developed as a more accurate, affordable way for designers, engineers, and manufacturers to design, visualize, and test models while minimizing the chance of mistakes. As CAD allows for easy modification, documentation,...

Is Graphite Toxic : How We Deal With the Dust Hazard

Is Graphite Toxic?Dust: a finely powdered substance of various matters, often suspended in the air. When that suspended matter is floating around someone machining graphite electrodes, it’s graphite dust. Anyone that has machined graphite knows that the particles generated from the machining process are very fine and have a tendency to remain airborne, even when a dust collector is in use. Unlike common household dust, graphite dust has characteristics that must be taken into consideration.Is There a Significant Graphite Dust Hazard?Dealing with graphite dust naturally brings up the question, is this stuff considered a hazard to the human body? Before...
