Need to pay attention to when using thimble oil in injection mold
In the process of beer making, the thimble and the thimble hole rub against each other. If the thimble (or thimble hole) is not frequently filled with thimble oil, the thimble will burn out or wear, and the thimble hole will wear out and increase the product. The thimble position is prone to flare, which affects the product quality (or assembly). Sometimes it is necessary to process the thimble position, or even break the needle, which hinders the smooth progress of production.
Therefore, we must spray thimble oil on the thimble regularly and regularly for lubrication and protection.
- The use of thimble oil
Thimble oil is generally a high-quality guide rail lubricant. The oil film is tough, does not lose, and has excellent lubrication, anti-rust and anti-crawling properties. It is used for plastic mold thimble (push rod) lubrication.

Use occasions
If the ejection resistance of the ejector pin is too large or the ejector pin does not retract smoothly during the mold beer process, eject ejection pin oil. In addition, it is necessary to assign someone to spray thimble oil on the thimble regularly (at least once per shift) every day to lubricate/protect it. -
Instructions
Before use, turn the thimble oil bottle (tank) upside down and shake it up and down several times to make the liquid in the bottle shake evenly.
When in use, a tube should be inserted into the nozzle hole, and the bottle body should be tilted (about 60° angle) or vertically upward, so that the nozzle and the thimble (thimble hole) are kept at a horizontal distance of about 20cm.
Align the outlet end of the tube with the thimble (thimble hole), press the nozzle with your index finger, and spray the thimble oil in a "jog" manner.
Spray thimble oil should be appropriate, not too much, so as to avoid waste or contamination of the product.
After the ejection needle oil work is finished, the ejection needle action should be carried out in the "manual state" (3 to 5 times), check the oil injection situation and effect, and improve it (if it is not sprayed well, it needs to be sprayed again).
The oil on the back model core or the oil from the thimble hole should be cleaned up with cotton cloth.

- Precautions
Do not spray thimble oil upside down, avoid contact with eyes, avoid inhaling spray, do not approach the fire source, and keep air circulation.
Bottles (spray cans) containing thimble oil should not be placed near high-temperature barrels/nozzles and hot melt heads to prevent thermal explosions.
After the ejector needle oil is finished or when it is not in use, the tube should be removed in time, the cover should be closed, and it should be sent to the specified place for safekeeping.
The bottle containing thimble oil should be placed in a cool and ventilated place, and avoid direct sunlight or exposure to an environment where the temperature exceeds 50°C.
Do not throw the empty bottle into the fire or pierce it after use.
It is strictly forbidden to spray thimble oil on the surface of flames or hot metal objects (such as high-temperature barrels, fire guns, etc.).
