The current economic trend has shifted from the regional economic model in the past to the economical trade. No matter whether it is a regional market or entering the market, high-quality performance cannot be denied. The vibration test is an indispensable tool to help your product jump into the ranks of high quality. When the product reaches the user's hands, there will be different states of vibration in the process, resulting in varying degrees of damage to the product. Any damage to the product is not what the manufacturer and the customer are willing to see. However, the vibration during the transportation process is unavoidable. If blindly increasing the packaging cost, it will bring serious and unnecessary waste, and vice versa. Packaging has caused high product costs and lost product image and market. These are not what we would like to see. The vibration test began to sprout about four or fifty years ago. When the theory was established, it did not help people believe it was important. Until World War II, many aircraft, ships, vehicles and equipment were found accidentally. The proportion of zero missing components is quite high. As a result of the research, it has been found that most of the components are unable to withstand the long-term resonance generated by their own structure, or that the loaded items are subjected to resonance, and the components are loosened and cracked. Loss of zero caused even a huge loss. When this result was announced, the vibration test received attention from all walks of life. They invested large sums of money and manpower to study it. Later, after the establishment of modern theory of vibration measurement analysis and simulation analysis, the method and logic of vibration testing have been continuously improved. In particular, the frequent circulation of goods today makes vibration testing more important. However, the purpose of the vibration test is to perform a series of controllable vibration simulations in the experiment, to test whether the product can withstand the test of transportation or vibration environment factors during the life cycle, and to determine the required standards for product design and function. According to statistical data, the 3% increase in design level will increase 20% recovery and reduce 18% of all unnecessary expenditures. Vibration simulation is based on different purposes and there are different methods such as resonance search, resonance dwell, cyclic scan, random vibration and stress screening, etc., while the vibration effect meter has: First, the strength of the structure. Second, the combination of loose. Third, the protection material wear. Fourth, the damage of the components. Fifth, poor contact of electronic components. Sixth, circuit short circuit and intermittent instability. Seventh, the standard deviation of each piece. 8. Screen out bad parts early. Nine, to find the resonance relationship between parts, structure, packaging and delivery process, to improve the resonance factor. The vibration test procedure shall evaluate the specifications of the specified test, the authenticity of the fixture design, the functional check during the test and the evaluation, review and recommendations of the post-test specimen. The essence of the vibration test is to confirm the reliability of the product and to screen out defective products in advance before leaving the factory, and to evaluate the failure analysis of defective products in order to become a high-level, high-confidence product.
In the CNC machining industry, in addition to metal CNC machining, plastic CNC machining is also relatively common. The two are also very different in terms of machining, the selected tools are also different, and there are also essential differences in speed and cooling. Due to the internal stress of the plastic, it is easy to crack and deform, so in the process of processing, it is necessary to control the speed of the tool and the problems of cooling. In short, CNC machining of metal parts and plastic parts is essentially different in the selection of tools, programming of tool paths, determination of tool speed and determination of cooling schemes. It is necessary to fully select and design materials according to material characteristics and processing experience. Only by determining various factors can we produce efficient and qualified products.
Machining metal parts and machining plastic parts are two separate departments at SCZY, each with its own processing equipment, tools and processing technicians. This ensures the durability of the equipment and the experience and professionalism of the technicians. Please contact us to discuss CNC machining knowledge.
