What Are Fusing Parts for OA Equipment?

For fusing sections of multifunction printers (MFP) and laser beam printers (LBP), the general method is fusing (fixing) powdered toner transferred to paper at high temperature and pressure. Resin parts are sorted into two types: “Fusing section parts” and “Parts around the fusing section.”
“Fusing section parts” are parts that support high-temperature heat sources of 200 to 350°C, and parts that are used close to the heat source. “Parts around the fusing section” are parts that transport paper before and after fusing, and covers that cover all fusing part.

Characteristics Required of the Material

Since the required heat-resistant temperature for “Fusing section parts” differs according to the fusing method, a grade with sufficient heat resistance is needed for the material. For parts that support the fusing section heat source, thermal storage is needed for thermal efficiency. Sliding characteristics are needed for parts that come into direct contact with high-speed rotating films.
However, “Parts around the fusing section” such as guides for transporting paper and covers covering the whole fusing section are designed to prevent paper jams and maintain the pressure in the entire longitudinal direction during fusion, which requires low warpage. To achieve thin-walled products, thin-wall flowability during molding is also needed.

シークレット カジノide for Fusing Parts of OA Equipment (Printer MFP, LBP)

For “Fusing section parts,” a wide selection is available according to the fusing method from the ultra-heat-resistant grade E5000 series to the シークレット カジノ000HF and SV6000HF series with other characteristics. When thermal storage and sliding characteristics are required, E5204L, E4205R, and シークレット カジノ205L are recommended with low thermal conductivity and good surface smoothness.
For “Parts around the fusing section,” the シークレット カジノ000HF and SV6000HF series are recommended for thin-wall flowability. Among these, シークレット カジノ808LHF and SV6808THF are recommended as grades with low warpage and good thin-wall flowability.
