What are our requirements for quartz glass processing customization?

The requirements of quartz glass processing customization usually include the following aspects:

Design and size requirements:

Accurate drawing design: providing detailed and accurate design drawings is the basis, and the drawings should clearly indicate the shape, size, angle, radian, hole location and other specific information of quartz glass products. For example, to customize an optical lens made of quartz glass, the drawing should be accurate to the radius of curvature, diameter, thickness and chamfer dimension of the edge of the lens.

Strict dimensional accuracy: according to different usage scenarios and purposes, the requirements for dimensional accuracy are also different. Generally speaking, for high-precision application scenarios such as semiconductor manufacturing and optical instruments, the dimensional tolerance may be required to be ±0.01mm or even smaller; For ordinary decorative or architectural purposes, the dimensional tolerance can be relatively relaxed, but it should also be controlled within a reasonable range to ensure the smooth installation and use.

Material requirements:

High-purity raw materials: For some fields that require high performance, such as optics and electronics, it is necessary to use high-purity quartz glass raw materials to ensure that its optical and electrical properties are not affected by impurities. For example, when manufacturing Shi Ying glass fiber in optical fiber communication, the purity of raw materials is extremely high, and the impurity content needs to be controlled at a very low level.

Uniformity of materials: The uniformity of materials directly affects the performance and quality of quartz glass products. The composition of raw materials should be evenly distributed, so as to avoid the unstable performance or defects of products caused by local composition differences.

Stability of materials: Quartz glass should have good stability during processing and use, including thermal stability and chemical stability. For example, quartz glass products used in high temperature environment need materials that can maintain stable physical and chemical properties at high temperature without deformation, softening and chemical reaction.

Processing technology requirements:

Cutting technology: Cutting is an important link in quartz glass processing, and the cutting edge is required to be flat and smooth, and there are no defects such as edge collapse and missing corners. The dimensional accuracy of cutting should meet the design requirements. For some special shapes, such as curve cutting and irregular cutting, advanced cutting equipment and technology are needed to ensure the accuracy and quality of cutting.

Grinding and polishing process: Grinding and polishing are to improve the surface smoothness and smoothness of quartz glass products. In the process of grinding, the pressure, speed and time of grinding should be controlled to avoid material loss and size deviation caused by excessive grinding; The polished surface should meet the specified smoothness requirements, such as optical quartz glass products, and the surface smoothness may be required to reach nanometer level.

Drilling technology: If it is necessary to drill holes in quartz glass, it is required that the hole position is accurate, the aperture size meets the requirements, and the inner wall of the hole is smooth without burrs, cracks and other defects. Appropriate drilling tools and methods, such as laser drilling and ultrasonic drilling, should be selected to ensure the quality of drilling.

Welding and gluing process: For some quartz glass products that need to be spliced or connected, the quality of welding or gluing is very important. The welding place should be firm and seamless, and the welding strength should meet the use requirements; Glue suitable for quartz glass material should be selected for gluing, and the sealing and stability of the joint should be ensured after gluing.

Quality inspection requirements:

Appearance inspection: check the appearance of quartz glass products for defects such as flaws, scratches, bubbles and impurities, and whether the surface flatness and smoothness meet the requirements. For transparent quartz glass products, it is also necessary to check their transparency and optical uniformity.

Size detection: use the corresponding measuring tools to measure the size of the product to ensure that the size deviation is within the allowable range. For example, the length, width, thickness, aperture and other dimensions of quartz glass products are accurately measured by calipers, micrometers, coordinate measuring instruments and other tools.

Performance testing: according to the specific use and requirements of the product, the corresponding performance testing, such as hardness testing, thermal stability testing, chemical stability testing, optical performance testing, etc. For example, for quartz glass lenses used in optical instruments, it is necessary to test the optical properties such as refractive index, transmittance and dispersion.

Packaging and transportation requirements:

Packaging requirements: Quartz glass products are fragile and need to be properly packaged. Packaging materials should have sufficient cushioning and protective properties, which can effectively prevent products from being damaged by collision, vibration, extrusion and so on during transportation. Generally, foam plastic, bubble film, cartons, wooden cases and other packaging materials are used for multi-layer packaging.

Transportation requirements: In the process of transportation, it is necessary to choose the appropriate transportation mode and means to ensure the stability and safety during transportation. For some large or special quartz glass products, it may be necessary to use special transport vehicles or transport racks for transportation. At the same time, we should pay attention to the environmental conditions such as temperature and humidity during transportation to avoid affecting the quality of products.
