Our strengths

1、Up to 2018, we have been engaged in the field of etching for 19 years. In 2015, the company invested in building a new industrial park in nantong, learned from the successful experience of shenzhen and kunshan branch, and committed to technical innovation, r&d, production and sales of 5-micron products in the middle and high-end market. Lizhi has become a century-old enterprise in China's etching industry!

2、The company has successively passed iso9001:2008 quality management certification and iso14001:2004 environmental management system. In 2016, the company passed ISO/TS 16949 certification and high-tech enterprise certification, and has obtained a number of property rights and patents. Zolida has been focusing on technology research and development and has cooperated with many universities, such as China southern airlines and Shanghai jiaotong university.

3、The company is a member of PCMI, the world etching association, which shares new information and equipment in the global etching industry.

4、The company has introduced a number of etching production lines, has a liquid medicine automatic addition system and regeneration system, the development of the company also pay attention to environmental protection, self-built large sewage treatment system, waste water reuse rate of more than 40%, is a rare in the metal etching industry to build a dedicated waterless treatment system of the manufacturer. The company aspires to become an environmental protection enterprise, green enterprise.

5、We can make slits with a gap of 5 microns and a thickness of 0.02mm. According to the product, the slit accuracy can reach +/-2 microns.

6、With shenzhen zhuolida, kunshan zhuolida and nantong zhuolida three production bases, the comprehensive area of more than 40,000 square meters. Nantong has built an industrial park, which involves etching, electroplating electrophoresis, anodic oxidation, laser welding, vacuum diffusion welding and other fields, providing customers with integrated solutions. The first floor of building 1, zhuolida, nantong is the electrophoresis workshop. The second and third floors are etching workshops, with more than 20 conventional, imported and customized non-standard precision etching lines, which can meet the requirements of production capacity and precision of various products. The fourth floor is the vacuum diffusion welding workshop. Building 2 is an electroplating industry.

           Introduction and characteristics of 5 micron slit: slit is mainly used in spectral instruments, etc. According to the working principle of modern spectral instruments, spectrometer can be divided into two categories: classical spectrometer and new spectrometer. Classical spectral instruments are instruments based on the principle of spatial dispersion. The new spectral instrument is an instrument based on modulation principle. Classical spectrometers are slit spectrometers. Modulation spectrometers are non-spatial spectrometers. According to the principle of dispersive component, spectrometer can be divided into: prism spectrometer, diffraction grating spectrometer and interference spectrometer.

          The difference between a slit plate and a polarizer: the polarizer passes through a specific crystal structure so that only light in the direction of transmission can pass through the polarizer. So when you go through the polarizer, natural light becomes polarized light, just vibrating in one direction. The slit does not have the ability to convert natural light into polarized light. When the width of the slit is close to or less than the wavelength of light, the light passing through the slit will have obvious diffraction phenomenon and the propagation direction will change. But the light still vibrates in all directions after it passes through.

       Chemical etching processing 5 micron slit advantage: chemical etching processing of the narrow seam smooth without burr and gap of the mouth, good straightness, produced by chemical etching can even, also can be slit sheet piece of black, after processing to take off for one piece packaged goods, affordable, suitable for mass production.

  •   Application fields of slits: 1. Incident slits: object points that form the spectrometer imaging system under the irradiation of incident light. 2. Collimating element: causes the light emitted from the slit to become parallel. The collimating element may be a separate lens, reflector, or directly integrated on a dispersion element, such as a concave grating in a concave grating spectrometer. 3. Dispersion element: grating is usually used to disperse the optical signal into multiple beams in space according to the wavelength. 4. Focusing element: focusing the dispersive beam so that it forms a series of images of incident slits in the focal plane, where each image point corresponds to a specific wavelength. 5. Detector array: placed in the focal plane to measure the light intensity of each wavelength image point. The detector array can be a CCD array or other kinds of optical detector array.

  • We can process 5 micron slit, 10 micron slit, 15 micron slit, 20 micron slit, 25 micron slit, 30 micron slit, 35 micron slit, 40 micron slit, 50 micron slit and so on. The seam is smooth without burr and can also be blackened with various slits. If you need to make 5 micron slit products, or you need to know the process and principle of slit, please contact us, we will serve you wholeheartedly!
