Silicone this material can be seen everywhere in life, this is a kind of polymer material with excellent physical and chemical properties, widely used in electronics, medical, automotive, aviation, daily necessities and other fields. Silicone perforation is another common silicone processing process, mainly used to make silicone tips, silicone diaphragms, silicone seals, silicone filters and other products.
Typically, silicone perforation for fine parts is extremely demanding, requiring precise, regular, burr-free micro-holes to ensure product quality and performance. MRJ-Laser chose a 5 watt UV laser for silicone material perforation, which produces well-punched holes with uniform outflow and high efficiency, making them pleasing to the eye.
Traditional silicone drilling methods mainly include mechanical drilling, EDM processing, ultrasonic processing, etc. These methods have some disadvantages, such as low processing efficiency, poor processing accuracy, unstable processing quality, easy to produce heat-affected zone and debris and so on. In order to solve these problems, laser drilling technology has emerged.
Laser perforation technology is a kind of non-contact processing method that uses high energy density laser beam to irradiate on the surface of silica gel to make it melt and gasify rapidly, so as to form micro holes on the silica gel. Facing this kind of precision processing, MRJ-Laser usually chooses the cold light processing like "UV laser", because the heat influence is smaller and the processing precision is higher.
UV laser perforation technology has the following five advantages:
- High processing efficiency, can realize high-speed continuous punching or flight marking, greatly improve the production efficiency.
- High processing precision, can realize micron or even nanometer fine processing, only according to the need to freely adjust the aperture size and shape.
- Good processing quality, playing the microporous smooth burr-free, no heat-affected zone and debris, will not damage the performance of the silica gel itself.
- Processing flexibility, can be punched for different shapes and thicknesses of silicone, no need to change the tool or mold.
- Low processing cost, no need to consume materials or consumables, simple maintenance, saving labor and material resources.
