Sintering Furnace for Moulded Rods/Tubes

Sunkoo supplies drying and sintering furnaces especially for the PTFE processing as well as preheating furnace for Molded rods/tubes.

There is also a furnace available for drying and sintering inline systems for the production of Moulded rods and tubes (development of Sunkoo). This high tech furnace  has an adjustable blind between drying and sintering zone, the lamellas of this blind can be cooled. As these two zones can not be influenced because of the stack affect, the required temperature profile can be well controlled in the drying as well as also in the sintering zone. This sintering furnace is available with different sizes. Herewith the furnace can be adapted to the respective requests and the available space.

FEATURES

  • Temperature sensor monitoring
  • Current monitoring
  • Superior-quality Heater Elements

PLACEMENT OF UNIT

  • When positioning the furnace, the minimum distance of the furnace and any wall is at least 30 cm. The furnace must be placed into a dry and heated room.
  • Make sure that the unit is placed on a heat-resistant surface.
  • The unit must not be exposed to direct sunlight.
  • Do not place any combustible objects near the furnace.

SWITCH ON THE FURNACE

  • Switch on the air switch at the rear of the furnace.
  • Switch on the power switch on the Panel.
  • Press Lift down key and lift will descend to its lower position.
    (Due to vibrations during transport particles of the firing chamber insulation will accumulate on the firing tray platform. They must be removed with a dry cloth)
  • Function of panel and LCD screen;
  • Place firing tray on the firing tray platform.

SWITCHING OFF THE UNIT

If the furnace is not used, the lift should be moved into the firing chamber. Closing of the firing chamber will protect the insulation and avoid the absorption of moisture. After the lift tray platform has been moved into the firing chamber, switch off the power switch (switch to OFF).

SAFETY ADVICE

For your personal safety we would like to ask you to read the following safety-relevant Information completely before starting-up the unit.
  • Do not place any objects near the lift tray.
  • Furnaces must not be operated without firing trays placed on.
  • During continuous firing (the furnace runs with maximum temperature), the temperature at the middle of top shell of the furnace may reach high temperature about 150℃. Other parts of top shell are about 70℃. Don’t touch the muffle cover.
  • If the furnace unit is connected to the mains supply, do not reach into the open firing chamber to avoid contact with live and hot components.
  • Pull the plug from the power unit each time before the furnace is cleaned.
  • It is not necessary to clean the interior of the firing chamber, cleaning of the casing with a wet cloth within regular intervals will ensure operational reliability.
  • Basically, no flammable liquids must be used for any type of cleaning work.

Vacuum Sintering Furnace Maintenance

Vacuum sintering furnace has been used for a long time,There will be some impurities left in the furnace. We need regular maintenance to avoid damage to the equipment.

 

  1. when the vacuum sintering furnace is deactivated, the vacuum condition in the furnace should be kept below 6.65*104pa.
  2. The dust cleaning furnace with ethanol or gasoline, moistened with silk, and dry.
  3. the vacuum system or sealing structure and other parts of the equipment should be cleaned with ethanol or gasoline, and coated with vacuum grease after drying, and then assembled.
  4. shell to avoid cleaning regularly, keep clean.
  5. the workpiece, car, material frame, workpiece and so on, after cleaning, and then put into the furnace, to prevent moisture, impurities into.
  6. when the transmission card, to limit and control the phenomenon of failure, should be immediately removed, to avoid forced operation, to avoid damage to equipment.
  7. drive parts should be regular refueling or oil change.
  8. vacuum pumps, valves, measuring instruments, thermal instruments and electrical components and other accessories, should be strictly in accordance with the instructions for use, maintenance and maintenance.
  9. in the maintenance of vacuum sintering furnace, in the case of power failure, and if in the case of live maintenance, it is necessary to ensure the safety of maintenance personnel and equipment.
