The fully automatic fuel injector spray testing machine HC-P024 is an automatic silicone oil spraying machine developed by Huanchou Machinery specifically for disposable medical syringe production lines. It is mainly used to apply a uniform and controlled amount of silicone oil to the inner wall of syringe barrels and the surface of plungers. The silicone oil coating helps improve lubrication performance, reduce friction between the plunger and the inner wall of the barrel, and provide smoother plunger movement during syringe use.
The machine adopts an atomized spraying system combining precision spray nozzles with a pressure adjustment system. The fine and uniform spray helps reduce localized oil accumulation and missed spraying, maintaining consistent lubrication performance for each syringe. Uniform oil spraying can also help reduce product defects such as plunger sticking and excessive resistance caused by uneven lubrication.
In terms of structural design, the machine can be used as a standalone unit or connected with other syringe production equipment, such as syringe printing machines and assembly machines. Photoelectric sensors monitor the material status in real time. The machine can automatically stop when there is no material and automatically restart after material is replenished, allowing smooth integration with upstream and downstream processes. This helps reduce manual handling and material transfer while improving the overall automation level of the production line.
The product-contact parts of the machine are made of stainless steel and food-grade materials, meeting the cleanliness and contamination-control requirements of medical device production. The machine can operate continuously and stably for 24 hours in a cleanroom environment.
The Fully Automatic Syringe Oil Spraying Machine is widely used in the production of various medical syringes, including disposable sterile syringes, vaccine syringes, and insulin syringes. It is particularly suitable for medium- and high-end syringe production lines where smooth plunger movement is an important requirement.
During operation, the operator only needs to set the corresponding oil spraying parameters on the touchscreen, such as spraying time, atomization pressure, and spraying position. The machine can then automatically complete the entire process of feeding, positioning, spraying, and unloading without manual operation of individual syringes. This improves production efficiency and helps reduce quality variations caused by inconsistent manual operation, making it a useful automated module for syringe production lines.
For daily maintenance, it is recommended to regularly check the spray nozzles for blockage and ensure that the oil circuit remains unobstructed. The filtration system should be cleaned as needed according to changes in silicone oil viscosity to maintain stable atomization performance and help extend the service life of the machine.
