For Silicon Mould manufacture ,Before cast urethane molding came along, there were limited economical options for producing small to medium runs for limited market releases and bridge applications. While injection molding is an excellent solution for mass production of identical products, it doesn`t offer a cost effective production solution for low volume needs or highly customized products. Answering this gap in production options involves lowering tooling costs and speeding up turnaround while using materials with equivalent properties and functionalities as those of injection molded products. Soft tooling through cast urethane processes has proven to be the best alternative to hard tooling for low volume, end use applications, for medical devices and training models, consumer products and more.Creating a soft tool for urethane casting begins with a master pattern. The surface of a master pattern is critical when forming a soft tool, as the surface is directly translated from the master pattern and onto the silicone. Our engineers typically equate the detail relay of platinum reinforced silicone to as fine as a strand of human hair. The most cost effective, quick turn master patterns are built using 3D printing. Two additive manufacturing technologies offer the surface finish, feature detail and speed for optimal soft tool creation Silicon Soft Part,Silicon Rubber Soft Part,Molded Silicone Part,Silicon Rubber Part Topwell Spring Development Ltd. , http://www.topwelldesign.com
In some dangerous working environments that are not suitable for manual work or artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; in the process of large-scale industrial production, using artificial vision to check the product quality is inefficient and the accuracy is not high. Machine vision inspection methods can greatly increase production efficiency and automation of production. Machine vision is easy to implement information integration and is the basic technology for computer integrated manufacturing. 
As shown above, it is a complete machine vision system, inside the left rectangular frame, belongs to the category of machine vision. The scope of machine vision includes cameras, lenses, light sources, and corresponding algorithms and software.
Machine vision technology in the field of security <br> <br> machine vision applications in the security field is widely used. such as:
Intelligent Transportation: In the transportation industry, compared with other identification technologies, machine vision has the advantages of low cost, strong stability, high accuracy, and a wide range of applications. It has been obtained in traffic monitoring systems for highways and highways at home and abroad. Wide range of applications, such as license plate recognition, body color identification, vehicle identification, illegal identification, traffic statistics, flow control, etc.
Binocular/Multi-view Stereo Vision: Binocular stereo vision technology is based on the principle of parallax, and uses an imaging device to acquire two images of a measured object from different positions. The three-dimensional geometry of the object is obtained by calculating the positional deviation between the corresponding points of the image. Information method. The core purpose of binocular stereo technology is to improve the accuracy of recognition. Because the three-dimensional geometric information of the object is contained in the field of view formed by stereo vision technology, it can effectively set detection rules, eliminate interference factors such as light and shadow, and greatly increase Intelligent analysis accuracy. With two cameras or multiple cameras, high-precision measurement of the three-dimensional position coordinates and attitude of the free movement of the space within the field of view can be performed to accurately track the moving target based on the calibration results. Since the binocular/multi-view stereoscopic vision can recognize the three-dimensional coordinates of the target, pose, relative distance, and spatial distance from the background environment, it can adapt to a complex tracking background environment. 
Instrument readings acquisition and monitoring: The current instrument is mainly divided into analog meters and digital display instruments. The pointer type instrument is simple and reliable, easy to maintain, and low in price. It is not only a variety of types, but also a large quantity, such as pressure gauges, dial gauges, dial gauges, car gauges, aviation instruments, etc. The digital display instrument is accurate and convenient for reading, measuring speed fast. In some cases, the reading of these instruments needs to be monitored. This is undoubtedly a boring and tiresome job for the calibrators. Affected by human subjective factors such as human observation angle, observation distance and fatigue strength, the error may be very large, the reliability is not high, and the verification efficiency is low and the labor intensity is high. The digital display meter reading technology of machine vision is to realize the interconnection, integration and monitoring of various digital instruments, and facilitate the realization of integrated control and control technology. 
Machine vision development prospects Machine vision can be used to accomplish tasks that are difficult to achieve manually, especially in systems that require high speed and high precision. For example, electronics manufacturing, automotive manufacturing, packaging and printing, chemicals, energy, processing machinery and other industries are users or potential users of machine vision. On the one hand, from the perspective of the international market, the largest application area of ​​machine vision is the semiconductor electronics manufacturing industry. China has become the world's leading manufacturing base. More than half of the world's mobile phones are manufactured in China. Many semiconductor companies have production plants in China. These companies require a large number of machine vision systems. On the other hand, China's industrial production is shifting from relying on cheap labor to a higher degree of automated production, which has also brought about a large demand for automation equipment. In addition, China's early automation of industrial equipment is generally low, requiring a large number of replacements, all of which constitute a huge market demand for automated equipment, including machine vision.
Machine vision is the use of machines instead of the human eye to make measurements and judgments. Through machine vision products (such as industrial cameras, etc.), the captured target is converted into a digital image signal and transmitted to a dedicated image processing system; the image system performs various operations on these signals to extract the surface features or behavior characteristics of the target, and then According to the result of the discrimination, the on-site equipment actions are controlled.
