How does RFH high power UV laser cut PVC film?

 

If you want to choose the most common material in life, PVC is definitely one of them. Manufacturers are racking their brains to optimize the production and processing of this material.

 

Before entering the processing, we must first know what PVC is.

 

This material is widely used in home improvement panels, doors and windows, toys, stationery, luggage and other fields. The main component of PVC is polyvinyl chloride, which is a kind of plastic, but this component has unique advantages.

 

1. The degree of softness can be adjusted freely

 

As a widely used material, PVC can be easily formulated with different softness according to any usage needs.

 

In actual cases, PVC can be used as a material from relatively hard boards or pipes to soft wire outsourcing, although the softness and hardness are different.

 

2. Easy to remove toxic substances

Considering the special use scenarios of stationery, toys, tableware and other consumer products, toxic and harmful materials cannot be used; PVC can easily remove these harmful substances in the refining process, making it non-toxic and harmless to people, safer and more environmentally friendly.

 

3. Easy to make PVC film

 

One of the most widely used applications of PVC in industry is that it is very easy to make PVC film.

Through the lamination process, PVC can be easily turned into a coating material, which is not easy to fall off after coating, and has stable chemical and physical properties.

The various advantages of PVC materials are mentioned above, but the characteristics of heat resistance also once made PVC a processing nightmare.

For a long time, PVC has been cut with various blades, but cutting with knives has limitations. It is difficult for tools to efficiently process irregular or special custom shapes.

 

How to cut PVC film?

Laser cutting is difficult, and once the cutting temperature is not properly controlled, burrs will appear on the edges.

RFH laser uses 20W high-power ultraviolet laser to cut PVC. The ultraviolet laser is used as cold light, which can easily solve almost all problems.

 

Smooth edges, high-efficiency processing, and good quality control are already the best solution for PVC cutting.

 

Recommended high power UV laser: RFH Expert III 355

 

Ultraviolet laser is used as cold light. The laser wavelength of RFH Expert III 355 is 354.7nm, and the repetition frequency covers a wide range (single pulse to 200kHz). It has natural advantages in processing materials with poor heat resistance like PVC.

 

RFH Expert III 355, as a high-power ultraviolet pulsed solid-state laser, has three major advantages.

Small size, convenient for equipment integration

 

RFH Expert III 355 is small in size and highly integrated with the body, so there is no need to expand the optical path, which can save a lot of expenses for the enterprise.

 

In terms of control, RFH Expert III 355 supports communication with the computer, using the RS232 serial port to externally control the laser, which is convenient for integration with various devices.

 

High precision, small processing heat influence

 

RFH Expert III 355 has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges.

 

In addition, because the pulse width is <25ns@50k, the heat-affected zone during processing is very small, and the high precision of ±0.02mm can be easily achieved.

 

Self-developed power control technology

 

There is a one-to-one relationship between the power supply and the laser, and the stability of the power supply control system determines whether the laser can maximize its performance during operation.

 

The all-digital intelligent power control technology adopted by RFH Expert III 355 is easy to operate and convenient to monitor.

 

Благодаря уникальной технологии управления модуляцией добротности он подходит для различных требований к управлению лазерными приложениями, а благодаря системе самоочистки внутренней полости лазер имеет длительный срок службы и стабильную работу.

 

При постоянном углублении RFH в области ультрафиолетового лазера высокая мощность 20 Вт уже может стабильно работать. В сопровождении системы управления мощностью собственной разработки вся лазерная система RFH будет продолжать стабильно работать.
