The principle of laser composite cleaning: The advantage of laser composite cleaning is that the continuous laser and pulsed laser are functionally composited at the same time to form a processing characteristic of 1+1>2. The principle is mainly through the semiconductor continuous laser as the heat conduction output, so that the attachment to be cleaned absorbs energy to generate vaporization and plasma cloud, and forms a thermal expansion pressure between the metal material and the attachment, reducing the bonding force between the two layers. When the pulsed laser outputs a high-energy pulsed laser beam, the generated vibration shock wave will cause the attachments with weak binding force to be directly separated from the metal surface, thereby realizing rapid laser cleaning.   Advantages of laser composite cleaning: 1. Apply to the cleaning of thicker coating materials. Due to the large energy output of a single laser with multiple pulses, the high cost of high-power pulsed lasers limits the laser cleaning of thick coating materials, and the use of pulsed laser-semiconductor laser composite cleaning can quickly and effectively improve the cleaning quality, and the substrate is not easy Causes damage, so it is suitable for cleaning thicker coating materials. 2. Apply to laser cleaning of high reflective materials such as aluminum alloy. Single laser cleaning aluminum alloy and other surface oxide layers has problems such as high reflectivity. However, pulse laser-semiconductor laser combined cleaning, due to the thermal transmission of semiconductor laser, increases the energy absorption rate of the metal surface oxide layer, making the pulse laser The beam can peel off the oxide layer faster, thereby more effectively improving the removal efficiency.

On July 9th, we shipped 10 sets of 30W laser cleaners to Japan. This customer has bought our laser cleaning machine many times. and he is very satisfied with our machine. Our laser cleaner also helped him open the Japanese market. Why choose Wuhan QUESTT ASIA Technology Co., Ltd.? Because we deliver high-quality products every time! We conduct strict quality control during every run to ensure consistency. More information: http://questtlaser.com

Questt Laser Cleaning Machine on 21th CHTF Each year, China Hi-Tech Fair (CHTF) is co-hosted in Shenzhen by Ministries and Commissions of the national government and Shenzhen Municipal People’s Government. For each CHTF, the total exhibition area exceeded 100,000㎡, nearly 3,000 exhibitors from more than 50 countries and over 500,000 visitors attended. Currently, it is the largest and the most influential scientific and technological fair in China and is renowned as “the No.1 Technology Show in China”. Questt Laser attend the 21th CHTF, the laser cleaning machine we show on the exhibition attract a lot of customers to pay a visit and we got many orders directly on the Fair. Laser rust removal machine is becoming more and more popular. It has big potential market. Welcome all you guys to resell our laser machines. Beblow are some photos taken on fair:

We are so glad to get a big order from Iran.  

The 500W IPG laser source we ordered from Germany finally arrived at our factory! The 500W laser cleaning machine will be ready to take videos soon.

On 3rd,May,2019, Questt and D1Solution have a successful meeting, deciding to establish a new combined company in Europe, which call "Questt Europe". We will move step by step and negotiate all the details later. The new company is mainly to open the big potential market in Europe, Questt Europe will offer the best serive and highest quality machines ! High quality is always our NO.1 goal!

Laser Cleaning Machine Wish Happy New Year 2019 The new year 2019 is already coming, laser cleaning machine offer the best wishes to all of you!        Laser cleaning equipment is a new generation of industrial surface cleaning laser system. It adopts the advanced laser source, laser             optical scanners and control system to meet the requirements of metal surface cleaning process. It can be customized according to               customer requirements to develop a dedicated cleaning system. Widely used for the surface laser degreasing, laser paint removal, laser       removal of zinc, laser film removal, laser cleaning, such as coating, etc   The laser-based surface pretreatment of industrial components and surfaces is often an economical alternative to conventional component cleaning. In addition to its low energy consumption, the media-free process does not require any chemicals or abrasives, which is why cleaning with light is particularly sustainable and environmentally friendly. To avoid damaging the surface of the component, industrial cleaning lasers with short pulses are used. Depending on the intensity, pulse duration, and wavelength, different effects and surface properties can be adjusted. The spectrum ranges from gentle cleaning to selective surface structuring. The effect of laser radiation depends on the absorption of the processed material (FIGURE 1).                                                  FIGURE 1. The absorption spectrum of different metals is shown. (Courtesy: Laser Zentrum Hannover [LZH])   Metals have a high reflectivity for the typical solid-state wavelength of 1064 nm, while impurities and oxides on the surface will absorb the laser radiation better. Moderate beam intensities can therefore be used to remove contamination from the surface without damaging the metal underneath. When cleaning with light, organic and acidic oxide contaminations are efficiently blown off from the surface of metallic components. By intensifying the laser parameters, metallic materials in the uppermost boundary layer (typically up to 5 µm) can be modified to create structures or roughness. One example is to improve the corrosion behavior of light metals and to increase the surface area by roughening. Laser beam cleaning offers high precision and reproducibility, therefore saving enormous costs in industrial series production. The investment in current laser technology is often many times cheaper than that in, for example, wet chemical alternatives. In addition, the running costs of highly efficient laser machines are usually significantly lower because of their low energy consumption (a few kilowatt hours) and moderate maintenance requirements. Significant savings in component unit costs can thus be achieved, especially with large part quantities and fully automatic processes.        The flexibility that laser cleaning offers makes it suitable for various industrial applications, including pretreatment of joints for bonding           and welding; accurate contour removal of coating to, for example, provide electrical contact; paint stripping for adhesive pretreatment;           and post-treatment of welding seams and descaling of steels prior to varnishing/cathodic dip coating

Questt Laser 200W fiber laser cleaning machine work in customer`s factory.      

The 20th China Internatinal Industry Fair last from 19th-23th, Sep, 2018.   Multi-functional laser cleaning and marking machine, our newest design, the first time to meet customers in such a big fair. This portable machine is very small, you cam put it in a suitcase and travel with it. You can do laser cleaning, laser marking and even laser cutting.     So many customers come to visit our booth and check the operation. We get a lot of orders on the fair!       We also gain a big support from the government officers, a happy photo we take together!
