Laser welding principle of electronic cigarette cartridges

Electronic cigarette bombs mainly refer to tobacco products that are similar to smoke and match electronic cigarettes (the properties need to be further determined). Heat-not-burn tobacco is a new type of tobacco product that has the characteristics of heating tobacco or tobacco extracts instead of burning tobacco. In order to prevent the smoke bomb from evaporating faster, the Laisai precision plastic laser welding machine will be used to seal and weld the upper and lower layers of the plastic shell of the smoke bomb.

Principle of laser welding of electronic smoke bomb plastic:

1. Fix two plastic parts with a fixture.

2 The upper and lower fixtures are closed to clamp the parts together, and then the laser welding energy is transmitted through the first part, and then absorbed by the second part. The absorbed near-infrared laser is converted into heat energy, which melts the contact surface of the two parts to form a welding area.

3. Apply pressure to make the welding area firm.

Advantages of laser welding of plastic electronic cigarette cartridges:

(1) Energy is concentrated, and excess energy consumption is extremely small.

(2) The volume of molten resin is small and there are few excess resin chips.

(3) Since it is not a contact welding process, the loss and deformation of the machine can be minimized.

(4) The laser path can be controlled by a simple optical refraction principle and is suitable for products of various shapes.

(5) The laser beam can be focused on a small area and can weld small and closely spaced parts.

(6) There are many types of weldable materials, and various heterogeneous materials can be joined together.

(7) It is easy to automatically weld at high speed and can also be controlled by digital or computer.

(8) The laser source can be shared on multiple devices through a switching device.
