Change your life, laser make science and technology of a new life in the future.
Industrial laser technology can apply to most of the material cutting marking engraving, laser laser equipment factory with the following China share USES the most widespread popularity of laser marking machine of plastic.
plastic marking machine: speed, suitable for automated assembly line production
plastic laser marking machine is receiving its inherent advantages, marking speed, computer control, simple operation, reduce the cycle of the product label, do not need expensive prophase work and the characteristics of the final finishing work, get the favour of plastic products manufacturer.
In addition, the laser can be easily integrated into an automated assembly line production.
Through a user friendly program interface, can quickly switch to the new processing;
Results are obtained with good repeatability and ageing resistance, wear resistance of products.
in the application of laser in plastic, not just limited to the logo.
In addition to the benefits mentioned above, three times the frequency of the laser frequency doubling laser and increasingly popularization, and the diversity of the combination of the material and craft, is for the application of laser in the plastic industry develop more new areas.
high precision plastic marking machine: excellent identification effect
for plastic marking machine, commonly used laser types are: short pulse tuning Q solid lasers and fiber lasers.
These lasers usually have less than the average power of 100 w, pulse duration between 10 to 100 ns.
Pulse frequency of 120 KHZ, and in the case of the fiber lasers, and even up to 1 MHZ.
In this way, the material and to identify the interaction between can fine-tune.
Short pulse time lead to tens of kilowatts of high pulse peak power to average of 10 w.
laser diode pumped laser is an efficient, it has a good ability to focus, is suitable for the fine marking.
Diode pump solid state laser with high beam quality, make the marking in the process of laser beam's focus for small diameter.
In this way, can achieve little on the small parts to 30 m precision marking track width.
plastic marking machine application prerequisites: used material suction light
on the market generally according to the laser wavelength laser can be divided into: 1064 nm (
Infrared)
、532nm(
Green light)
And 355 nm (
Uv)
。
Infrared belongs to & other;
Thermal light & throughout;
, green light and ultraviolet belongs to & other;
Cold light & throughout;
。
Relative with green light and ultraviolet light, red light is the most widely used, and the cost is cheap, suitable for most of the non-metallic materials cutting engraving marking.
And in special marking applications, using UV wavelength, created the laser mark on the plastic new possibilities.
Short wavelength and plastic composites to produce photochemical reaction directly, without heating, thus no material damage;
Especially a few more selective materials, plastic containing flame retardants, or sensitive electronic components, etc.
The laser is under very high speed of high contrast of marking, without any negative influence on the surface quality.
in industrial laser applications, the used materials must absorb light, if in no absorption of light materials, laser fundamental won't produce any effect on it.
Plastic biological macromolecular structure usually only absorb ultraviolet range and far infrared (
IR)
Within the scope of the light (
At 10.
6 m)
。
Engineering plastic additives, fillers and pigments in a large impact on the absorption characteristics of materials, so that the plastic can better in the near infrared range, or visible within the scope of green laser absorption laser beam.
Through this method, can obtain higher plastic marking machine marking speed and better contrast.
so in order to make the material in a short processing time, high-definition, high quality durable marking effect, requires special deployment of laser sensitive additives.
They are drastically increase the ability of the material tag.
China laser equipment factory professional laser equipment manufacturers, products include: optical fiber laser cutting machine, uv laser marking machine, laser marking machine, ningbo embroidered laser cutting machine, and so on.
