Injection molding plants need to process products according to customer requirements to ensure customer satisfaction. So, what are the appearance requirements for plastic injection products? 1. Plastic injection molding is carried out according to the requirements of written documents, without damage, blur, uneven thickness, falling off, scratches, etc. 2. The shape of the edges and corners should meet the requirements of the drawings, the guide circle should be flush, and there should be no abnormal edges and corners; the surface is smooth without obvious deformation, and the exposed surface has no convex points and convex shells. 3. The appearance color of plastic parts should be made according to the standard of qualified samples or written requirements, the color difference of batches is not obvious, and the gloss consistency is strong; there should be no obvious scratches on the exposed surface, except those that can be wiped off While many people now consider 3D printing to be the dominant form of rapid prototyping, CNC machining is also an important process for creating prototype parts.rapid prototype services Is CNC machining suitable for prototyping?
While 3D printing can be a great option for what looks like a prototype, CNC machining is often preferred for these functional prototypes that require strength, mechanical stability, or other properties that additive processes cannot provide. After all, not many end-use parts are made using 3D printers. CNC machining can be an excellent choice for prototyping, but its suitability depends on the nature of the prototype. For what purpose are prototypes used? What material will it be made from? What material to make from the final part? These and other questions will ultimately guide users to the most appropriate prototyping method. like: What are the advantages and disadvantages of rapid prototyping? Rapid Prototyping - Technical Features of Free Forming What are the characteristics of rapid prototyping technology Rapid prototyping technology is a new technology that integrates advanced technologies such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer numerical control (CNC), precision servo drive, laser and material science. Its basic idea is: Any three-dimensional part can be regarded as the superposition of many two-dimensional plane contours of equal thickness along a certain coordinate direction. Therefore, according to the three-dimensional design model of the product formed on the computer, the three-dimensional model in the CAD system can be divided into a series of plane geometric information, that is, sliced into layers to obtain the contours of the cross-sections of each layer. Or hot-melt materials, etc., to form each cross-sectional profile and gradually superimpose it into a three-dimensional product. With the rapid development of the RFID terminal market, more and more terminal manufacturers have sprung up. 13.56 mhz RFID cards Faced with many brands, how do companies choose RFID product and solution suppliers?
First of all, it depends on whether the supplier has the terminal R&D and production capacity. Secondly, enterprises should choose terminal manufacturers according to their own needs and product functional requirements. In addition, enterprises should also pay attention to the service attitude of the manufacturer, because the perfect pre-sales and after-sales service can ensure that any technical problems and after-sales problems will be answered by a professional team once the purchase occurs, and high-quality service can greatly reduce the efficiency cost of customer use. , the monetary cost. like: Why RFID has a broad market development space?

1. Action distance The action distance required by the application depends on the positioning accuracy of the electronic tag and the minimum distance between multiple electronic tags in practical applications. 2. Working frequency The power consumption of the system directly affects the recognition distance of the system. Taking into account the health and safety of operators, when selecting the operating distance of the system, the power consumed by the system to meet the requirements of this distance must be considered 3. System power consumption Radio frequency identification systems of different frequencies have different characteristics, technical indicators and application fields. RFID products with different frequencies have different product identification performance. This must be done according to the specific needs of customers in equipment selection. 4. Simultaneous readability of multiple electronic tags Considering that the system needs to use multiple electronic tags to read at the same time, it is also very important to examine the performance of the simultaneous reading of multiple electronic tags provided by the reader. like: What is the process of reading the RFID card?
