The sterile medical test tubes that are necessary in hospitals are all made by professional medical test tube injection molding machines. The following are the operating steps of the injection molding machine for medical blood tube. 

Injection molding machine for Medical blood tube -- Lisong

Operation flow of injection molding machine for medical blood tube

Nozzle advances → injection → hold pressure → pre-molding → shutdown → nozzle retreat → cooling → mould opening → ejection → needle withdrawal → door opening → door closing → mould closing → nozzle advance.

Injection molding machine operation items: Injection molding machine operation items include three aspects: control keyboard operation, electrical control cabinet operation and hydraulic system operation. The selection of injection process action, feeding action, injection pressure, injection speed, ejection type, temperature, current, and voltage monitoring of each section of the barrel, adjustment of injection pressure and back pressure, etc. are carried out respectively.

Action selection during injection

Generally, injection molding machine for medical blood tube can be operated manually, semi-automatically and fully automatically.

Manual operation is in a production cycle, each action is realized by the operator flipping the operation switch. It is generally selected when the test machine adjusts the mold.

In semi-automatic operation, the machine can automatically complete a work cycle, but after each production cycle, the operator must open the safety door, remove the workpiece, and then close the safety door, so that the machine can continue production in the next cycle.

In fully automatic operation, the injection molding machine can automatically enter the next work cycle after completing a work cycle. There is no need to stop the machine for control and adjustment during normal continuous work. But it should be noted that if you need to work fully automatically, please note:

• Do not open the safety door in the middle, otherwise the automatic operation will be interrupted;
• Add materials in time;
• If you choose the electric eye sensor, you should be careful not to cover the electric eye.

In fact, in fully automatic operation, it is usually necessary to temporarily stop in the middle, such as spraying mold release agent on the machine mold.

Injection speed

Generally, the control panel of injection molding machine for medical blood tube has two knobs: fast and slow, to meet the requirements of injection speed. In the hydraulic system, a large-flow oil pump and a small-flow pump are provided for supplying oil at the same time. When the oil circuit is connected to a large flow, the injection molding machine realizes rapid mold opening and closing, rapid injection, etc., when the hydraulic oil circuit only provides a small flow, various actions of the injection molding machine proceed slowly.

Ejection form

Injection molding machine for medical blood tube have two types of ejection: mechanical ejection and hydraulic ejection. Some are also equipped with a pneumatic ejection system. There are two types of ejection times: single and multiple. The ejection action can be manual or automatic.

The ejection action is started by the mold opening stop limit switch. The operator can achieve this by adjusting the ejection time button on the control cabinet as required. The ejection speed and pressure can also be controlled by the switch on the control cabinet, and the back and forth distance of the thimble movement is determined by the travel switch.

Conclusion

Operating injection molding machine for medical blood tube is not easy thing. Every steps will have impact on the formation of medical test tubes.
