reaction injection moulding Applications

A reaction injection moulding, there is a nearly 40-year history of the casting mold, plant, and equipment has a relatively strong strength. Now, after the reform and opening up the development and improvement of its main mold processing MASTER reaction injection moulding  should be first-class. Current problems are relatively lag mold clamp processing, becoming the last one mold manufacturing process "bottleneck." Therefore, to work hard in the mold fitter process, the overall balance of the mold processing, can be greatly improved our casting mold, die casting mold output capacity. This could also be casting mold industry a universal problem. (1) High-speed milling will be more widely used In recent years, the development of high-speed milling abroad, the spindle speed of up 40000-100000r / min, rapid traverse speeds up to 30-40m / min, tool change time can be increased to 1-3s. This greatly improves the processing efficiency, such as in the processing die casting, can be increased 7-8 times, and the obtained surface roughness ra≤10μm. plastic drawer mold  accuracy up to 10μm. It may also be processed hardness 60hrc modules, poses a challenge to the EDM. Therefore, the development of high-speed milling technology will promote the development of the casting mold processing technology. (2) reaction injection moulding speed scanning and digitizing system will play a greater role Renishaw company Die scanning system has been applied in our country more than 200 mold factory point to good effect. The system offers many features from the model or physical processing of the scan to the desired model needed, greatly reducing the casting mold development and manufacturing cycle, as renscan200 fast scanning system can be quickly installed on existing CNC milling machines and machining centers achieve rapid data acquisition with Renishaw sp2-1 scan head thin wall injection molding  is Renishaw tracecut software can automatically generate a variety of different data systems cad data processing procedures and different formats. (3) reaction injection moulding polishing will be automated, intelligent direction Mold surface finish is a good one mold failed to solve the problem, it is also a large mold fitter labor intensity, becoming one of the bottlenecks reasons. Particularly reflected in the hardness of the large metal, casting molds for the final assembly process. China is still dominated by hand, not only inconsistent quality, long period, poor workers and the working environment, which restricts the casting mold to a higher level of development. Therefore, the study of polishing automation, intelligence is a priority. Of course, because of the casting mold, die casting mold cavity complex, polished automation, intelligent has some limitations.
