The acceptance expert group consisting of five experts including China Metrology Institute, Hangzhou Aihua Instrument Co., Ltd., and the Fifth Institute of Electronics of the Ministry of Industry and Information Technology unanimously stated that the study of susceptor strain sensitivity is almost blank at home and abroad. Good research prospects, I hope that the project team will strengthen follow-up research and make full and solid preparations, laying the foundation for the revision of GB/T 13823.6-1992 "Standard strain sensitivity test for vibration and impact sensor calibration method" and strive for Modify the ISO international standards in related fields.
A vibration sensor is a sensor for detecting an impact force or an acceleration. A piezoelectric device that generates a charge by applying a stress is generally used, and a sensor that can be detected by other materials and methods is also used.
Vibration testing has a very important position in the field of modern engineering, and it has received widespread attention. Many departments and units are conducting practical exploration and research, and new testing methods and methods are emerging. This is because vibration is widely existed in nature and engineering. Phenomenon, it is inseparable from the vibration test to use it for the benefit of mankind or to reduce its harm.
The vibration and impact sensor base strain sensitivity automatic test device developed by the project uses electromagnetic excitation technology to produce a controllable steady-state sinusoidal base strain in the range of (1~6) Hz, which can be the product of domestic mainstream sensor manufacturers. Provide technical guidance for R&D and production, provide technical support for high-end sensor technical indicators for export, and provide strong protection for the safety performance of sensors widely used in the fields of national defense, advanced manufacturing, and construction industries.
Vertical Single Slide Injection Molding Machine
Vertical Injection Molding Machine
1. Each plastic cavity can be taken out by a simple manipulator, which is conducive to precision molding.
2. In small batch trial production, the mold structure is simple, low cost, and easy to unload.
3. It is easy to ensure the consistency of resin fluidity and mold temperature distribution in the mold.
4. After many earthquakes, the vertical machine has better seismic resistance than the horizontal machine due to its low center of gravity.
5. Equipped with rotating table, moving table and tilting table, it is easy to realize insert molding and in-mold combination molding.
6. The belt conveyor is easy to be installed in the middle of the mold, so as to realize the automatic production of molding.
7. Generally, the mold locking device is open around, and it is easy to configure various automatic devices, which is suitable for automatic forming of complex and delicate products.
8. The weight of the mould is supported by the horizontal formwork for opening and closing up and down. The phenomenon that the formwork cannot be opened and closed due to the forward fall caused by the gravity of the mould similar to the horizontal machine will not occur. It is beneficial to maintain the accuracy of machinery and mold for durability.
9. It is easy to realize the molding of the insert. Because the mold surface is upward, it is easy to put the insert into the position. The lower template is fixed and the upper template is movable. If the belt conveyor is combined with the manipulator, it can easily realize the automatic insert molding.
10. The injection device and mold locking device are located on the same vertical centerline, and the mold is opened and closed in the up and down directions. Its floor area is only about half of that of the horizontal machine, so it is about twice as productive.
