What measures have been taken to improve the molding accuracy and surface quality of silver acrylic sheet products?
1. Precision system integration control
Hangzhou Oleg International Trade Co., Ltd's cast silver acrylic sheet adopts precision system integration control. This advanced technical means plays a key role in improving the molding accuracy and surface quality of silver acrylic sheet. During the production process, from the preparation of raw materials to the molding of the final product, the entire process is under strict system monitoring. By precisely controlling key parameters such as temperature, pressure, and flow rate, the stability and consistency of each silver acrylic sheet during the molding process are ensured. For example, in the hot forming stage, the system can accurately adjust the heating temperature and time according to the thickness and size of the sheet, so that the sheet is heated evenly, thereby avoiding deformation problems caused by local overheating or overcooling, and greatly improving the molding accuracy. In processes such as extrusion and calendering, the system's precise control of pressure ensures the uniformity of the sheet thickness and further improves the surface quality of the product. This precise system integration control not only improves production efficiency and achieves high output, but more importantly, provides a solid guarantee for the high-quality production of silver acrylic sheets, so that its quality not only meets but even exceeds the GB/T7134-2008 quality product standard.
2. Strict selection of raw materials
High-quality raw materials are the basis for producing high-quality silver acrylic sheets. In the procurement of raw materials, strict screening standards and supplier evaluation systems have been established. For the basic resin materials used in silver acrylic sheets, suppliers are required to provide detailed product specifications and performance parameters, and conduct strict quality inspections. Ensure that the purity, molecular weight distribution and additive content of raw materials meet the high standards set by the company. For silver flash additives, they are carefully selected to ensure that their particle size is uniform and well dispersed, and they can be evenly distributed in the acrylic sheet, thus creating a stable and elegant silver flash effect. Only raw materials that have passed layers of screening can enter the production link, which guarantees the molding accuracy and surface quality of silver acrylic sheet products from the source, and provides a good basic condition for subsequent processing technology.
3. Advanced processing technology and equipment
When cutting silver acrylic sheets, high-precision laser cutting equipment is used. Laser cutting has the characteristics of narrow incision, high precision and small heat-affected zone. By precisely controlling the parameters such as laser power, cutting speed and focal length, the plate can be accurately cut, and the cutting accuracy can reach ±0.1mm or even higher. This high-precision cutting process not only ensures the dimensional accuracy of the silver acrylic plate during processing, but also the incision is flat and smooth, without the need for secondary grinding, which greatly improves the surface quality. Laser cutting can also avoid the problems of plate edge cracking and deformation that may occur in traditional mechanical cutting methods, further improving the molding accuracy and overall quality of the product.
For silver acrylic plate products that need to be drilled, the company has introduced advanced CNC drilling equipment. CNC drilling equipment can accurately control the position, diameter and depth of drilling through programming. During the drilling process, special drill bits and cooling lubrication methods are used to effectively reduce the heat generation during the drilling process and avoid deformation and surface burns of the plate due to overheating. The drilling accuracy and surface quality are ensured by optimizing drilling parameters, such as the matching of feed speed and rotation speed. The drilled hole wall is smooth, and the hole diameter tolerance is controlled within a very small range, which meets the needs of various high-precision application scenarios.
Thermoforming is an important part of the processing of silver acrylic sheets, which directly affects the molding accuracy and surface quality of the products. Advanced vacuum thermoforming technology and hot pressing molding technology are adopted. In the vacuum thermoforming process, the heating temperature, vacuum degree and molding time are precisely controlled so that the sheet can fit closely to the mold surface, thereby obtaining a high-precision molding shape. In order to improve the surface quality, the mold surface is specially treated to make its surface roughness extremely low, so that the surface of the formed silver acrylic sheet is as smooth as a mirror. In the hot pressing molding process, a high-precision pressure control system and a mold temperature control system are used to ensure that the sheet can be evenly pressurized and heated under high pressure and high temperature conditions to achieve a high-precision molding effect. In addition, the company continues to develop and improve the thermoforming process parameters, and formulates personalized thermoforming solutions according to different product requirements and sheet characteristics to further improve the molding accuracy and surface quality of the product.
4. Quality inspection and control system
In the production process of silver acrylic sheets, strict quality inspection is carried out after each production process is completed. For example, after the sheet extrusion process, an online thickness gauge is used to monitor the thickness uniformity of the sheet in real time. Once the thickness deviation is found to be beyond the allowable range, the production parameters are adjusted immediately. After the hot forming process, the molding accuracy of the product is tested by optical inspection equipment, including dimensional accuracy, shape accuracy, etc., and the products that do not meet the requirements are reworked in time. This process inspection mechanism can timely discover quality problems in the production process and prevent unqualified products from flowing into the next process, thereby effectively ensuring the molding accuracy and surface quality of the product.
After the product is produced, the company sets up a special final inspection area to conduct a comprehensive quality inspection of the silver acrylic sheet. A variety of advanced inspection equipment and means are used, such as a three-coordinate measuring machine to accurately measure the dimensional accuracy of the product, a surface roughness meter to detect the surface roughness of the product, and a gloss meter to measure the gloss of the product. The appearance quality of the product is strictly visually inspected to ensure that there are no defects such as bubbles, scratches, impurities, etc. on the surface of the product. Only products that pass all inspection items can be judged as qualified products and allowed to be sold out of the factory. This strict quality inspection and control system ensures that every piece of silver acrylic sheet shipped out of the factory has excellent molding accuracy and surface quality, meeting customers' demand for high-quality products.
5. Optimization measures for the characteristics of silver acrylic sheet
Since the silver acrylic sheet material contains tiny silver flashes, special attention should be paid to the balance between the flash effect and molding accuracy during the production process. Hangzhou Oleg International Trade Co., Ltd optimizes the raw material formula and processing parameters to ensure that the silver flash additives are evenly distributed in the sheet without affecting the molding performance of the sheet. During the thermoforming and processing process, the temperature and pressure are precisely controlled to avoid the aggregation or displacement of silver flash particles due to improper process conditions, thereby ensuring that the product has good molding accuracy while presenting a stable and elegant silver flash effect.
For the surface treatment of the silver acrylic sheet, advanced polishing technology is used. After the sheet is formed, the surface of the sheet is made to achieve an extremely high degree of finish through special grinding and polishing processes. In order to protect the surface quality, surface coating treatment can also be carried out according to customer needs, such as coating a layer of wear-resistant and scratch-resistant protective film to further improve the surface quality and service life of the product. In addition, for different application scenarios, the company can also provide customized surface treatment solutions, such as frosting, texture treatment, etc., to meet customers' diverse needs for product appearance and functions.
