What does melter mean?
A melter is a person, machine, furnace, or chamber whose purpose is to melt material. Its most characteristic application is in manufacturing, where a melter heats and liquefies a carefully prepared batch so that it can be formed, mixed, or processed. In glassmaking, for example, the melter helps turn raw ingredients into a smooth molten mixture suitable for shaping. The word can also denote a device intended to melt ice or snow. Although the general verb “melt” is far more familiar, “melter” is useful when naming the specific person or mechanism performing the operation. It should not be confused with “smelter,” which refers more narrowly to equipment or an establishment for smelting metal-bearing ores or other materials.
A furnace, vessel, machine, or other device in which material is melted, especially during industrial production.
"Molten glass was drawn from the melter and transferred immediately to the forming equipment."
Often used in glassmaking and other manufacturing contexts; the precise technical meaning varies by industry.
A person or mechanism whose function is to melt a particular substance.
"The operator checked the melter before beginning the next production cycle."
The standard plural is “melters.”
"Two melters were installed in the new production facility."
A melter is named for what it does: its job is not merely to heat a material, but to transform it into a smooth, molten mass.

Where does melter come from?
“Melter” was formed in English by adding the agentive suffix “-er” to “melt.” The verb “melt” descends from Old English meltan, which had relatives in other Germanic languages, including Dutch smelten and German schmelzen. The related forms “molten” and “smelter” also preserve the idea of softening or liquefying material through heat.
