Hot Fuser

Product Description

Leveraging on our state-of-the-art facilities for printing and digital imaging, we are manufacturing and supplying Hot Fuser. These fusers are manufactured using the finest quality of thermo plastic resin and metal oxide obtained from the authentic vendors. The clients can avail the fusers from us in different customized sizes, models and specifications as per their requirements. We precisely check the Hot Fuser on efficiency and quality parameters before offering to clients at reasonable price.

Further Details of Hot Fuser:

The toner from Laser and Photocopiers are based on a Thermo plastic resin and metal oxide (iron oxide). The metal oxide gives the black colour, whilst the Thermoplast (Styrene Acrylate) acts as a binder to hold the pigment particles together. In both Laser printers and Photocopiers the toner is transferred to the substrate which then passes through heated rollers to fuse the toner onto the substrate. The toner for Photocopiers (600 DPI and 1200 DPI) Laser printer are all slightly different but basically of the same make up and melt between 100^oC - 150^oC. The main differences are in the toner particle size and the temperature at which they are fused. The fusing temperatures are all slightly different for comparable models, but are typically: Photocopiers - 120oC 300 to 600 DPI ,Laser Printers - 175^oC to185^oC 1200 DPI The time taken to fuse the toner in the above machines, again will vary but is in the order of 0.1 seconds. The copiers and printers are designed around the imaging on paper and coated film which are porous substrates.

WHY FUSE AT LOWER TEMPERATURE ?
The Polyprint offset printing plate is of a completely different make up and the fusing time by Laser printer is not long enough to fuse the toner into its surface adequately.  Part of the development work for Polyprint involves additional curing of the toner into the plate at various temperatures and times. The ideal conditions were found to be for 90 seconds with gentle air movement. A higher temperature for a shorter time could be used, however the sharpness of the image deteriorates and shadow tones closed up. Forced air, such as curing through a Jet Drier had the same effect.

WHY TO BAKE THE PLATE IN ASIATECH HOT FUSER ?
To always print long run jobs, trouble free from minute scumming and wreaking of image, it is advisable to bake the plate in the hot fuser for proper toner adhesion.
