Brief analysis of plastic mold industry problems and development suggestions
2026-03-07
With the advancement of processing technology and production equipment, thermoplastic/thermosetting plastic products treated with plastic materials as raw materials and processed by different production and processing processes such as hollow molding are more and more widely used in different occasions of production and life, light industrial machinery, agriculture and forestry. In different industries such as transportation, plastic products are widely used.However, since plastic products are high-molecular polymers, how to deal with waste plastic products has become a head-scratching problem. Simple landfill disposal, plastic products are difficult to decompose and pollute the soil environment. If incinerated, the auxiliary materials added in the plastic production process will produce toxic and harmful gases and pollute the air environment.It is understood that the emergence and development of the recycled plastic industry is expected to solve the problem of plastic product pollution. In recent years, people have paid more and more attention to the quality of the living environment, the public's awareness of environmental protection has been continuously enhanced, and the price of crude oil has risen, which has pushed the price of plastic raw materials higher, and the clean and environmentally friendly recycled plastic industry has received a good opportunity for development. And industrial structure adjustment, my country's recycled plastic industry has made great progress and is developing towards the direction of high quality, multiple varieties and high technology.Although my country's recycled plastic industry has a bright future, it still faces many problems in the actual development process. On the one hand, due to the wide source of recycled plastic, its quality is uneven, and the performance between batches is also very different, resulting in a relatively low quality stability of recycled plastic; on the other hand, the cost of recycled plastic is relatively high, and its price is high. price of virgin plastic. In addition, from the current overall situation of the recycled plastic industry, domestic waste plastic recycling enterprises are still dominated by small and medium-sized enterprises, and the industry concentration is relatively scattered. Because waste plastic recycling is a complex process, the technical requirements are also relatively high. However, my country's domestic recycled plastic industry is still dominated by physical recycling, which undoubtedly hinders the development of the entire industry to some extent.Experts believe that under the background of vigorously promoting circular economy, promoting traditional industrial reform, and promoting environmentally friendly sustainable development, although there are still various problems in the domestic recycled plastic industry that need to be solved urgently, the development prospect of the recycled plastic industry is still bright. Domestic plastic industry enterprises should seize the opportunity to develop recycled plastic production projects and promote the green development of the industry.Some domestic plastic molds begin to replace imported productsThe mold industry belongs to the basic industry in the national economy, which involves various industries such as machinery, automobile, light industry, electronics, chemical industry, metallurgy, building materials, etc., and has a wide range of applications. my country's industry has developed rapidly, among which the development of automobile manufacturing, IT manufacturing and medical equipment has brought opportunities for the entire mold industry to usher in development opportunities.In recent years, domestic enterprises have continued to improve mold technology and products. Therefore, some plastic molds or injection molded parts have begun to circulate internationally, successfully entering the supply chain system of some high-end industries, and even replacing some imported products. dependency. But it is undeniable that only a few of them have entered the international high-end market.With the improvement of the technical level of my country's mold industry and the gradual increase of product levels, some international host industry supply chain systems are now further inclined to domestic enterprises, which will be an opportunity and a challenge. It is understood that by 2015, the independent matching rate of molds required by the Chinese market will reach more than 85%, and the independent matching rate of medium and high-end molds will increase significantly.Some experts pointed out that in the future, my country's mold industry will not only continue to improve production capacity, but also focus on internal structural adjustment and technological development. It is mainly the adjustment of enterprise structure to specialization, the development of product structure to mid-to-high-end molds, the improvement of import and export structure, the analysis and structural improvement of mold forming for automobile panels, multi-functional composite molds and composite processing and laser technology in mold design and manufacture application, high-speed cutting, ultra-finishing and polishing technology, and the direction of informatization.

Siege of "smart manufacturing", a rising star of machine vision
2026-03-07
Machine vision is one of the key points to realize Industry 4.0.Beginning in the 1760s, the Industrial Revolution had an important impact on the course of human history."Industry 1.0" is machinery manufacturing, that is, the era of manufacturing that realizes the mechanization of factories through the introduction of machinery and equipment. Entering "Industry 2.0" in the 1940s, the era of electrical and automation created an efficient model for mass production of products. The informatization that started in the 1970s and continues to this day is "Industry 3.0", which stores information through digital technology to facilitate the management of factory decision makers. Today's "Industry 4.0" era is the era of intelligent manufacturing, which puts forward higher requirements for productivity, and the driving force behind it is most likely the booming artificial intelligence technology.In the first three industrial revolutions, China failed to catch up. In the 18th century, China was in a period of feudal isolation; in the 1940s, China was in turmoil; in the 1970s, China was just starting to develop. Therefore, for the current China, it is very important to seize the opportunities of the intelligent manufacturing era of "Industry 4.0", with the national security, the increase in talent training, and the abundant resources.In the past fifteen years, the scale of China's manufacturing industry has grown wildly at a rate of nearly 30 times. By 2020, China's industrial added value will reach 31.3 trillion yuan, ranking the world's largest manufacturing country for 11 consecutive years, accounting for 30% of the global market share. .In the "Made in China 2025" plan proposed in 2015, industrial computer vision applications occupy an important position.In the intelligent world, machines can replace manpower, improve safety and efficiency, and bring disruptive changes to the entire industry with powerful data collection and analysis capabilities.The key to realizing all this is to first light up a pair of "wisdom eyes" for the machine.There is an old saying in the AI industry: those who have vision win the world.From face recognition to industrial intelligence, the implementation of computer vision has now crossed the semiconductor, automobile, aviation, new energy, precision optics and other industries, such as lens sorting, bearing detection, special barcode design and identification, polarized bending film, mold detection, AVI detection, etc. Taking chip inspection as an example, computer vision algorithms based on deep learning can complete automatic clustering analysis of 100 million-level crystal structures: the detection rate exceeds 99.99%, the processing efficiency of a single process is increased by 96%, and the processing efficiency of AI automatic full inspection is improved. 90%.The proportion of traditional manufacturing in the national economy is the future market capacity of intelligent manufacturing. According to data from the National Bureau of Statistics, in 2019 and 2020, the scale of China's industrial added value exceeded 31 trillion. A 1-2% increase in efficiency in the industrial sector means hundreds of billions of economic value added.The complex machine vision market is a market that is big enough and far enough away, and it is also a market that requires many players to work together, give full play to their strengths, jointly increase demand and promote the level.In the vast ocean of intelligent manufacturing, a group of people from all walks of life have emerged with the process of China's industrialization.Among this group of people, there are traditional visual manufacturers who have worked hard all the way through the curve of time and become strong and strong; Hai Dayu, who entered the security market and took the lead in breaking through the defense lines of international giants; The AI Four Little Dragons are half of the computer vision market.At the same time, a large number of cutting-edge AI companies are also chasing after each other along the visual road that their predecessors have cultivated, making steady progress and progressing step by step.Relying on their own technical strength, they cut into various sub-fields and conquered the city inch by inch, and they have the potential to seize the trend of the intelligent era.

The market pattern of stamping dies still needs to be adjusted and optimized
2026-03-07
In recent years, the level of stamping die in my country has been greatly improved. Large stamping dies have been able to produce a single set of dies weighing more than 50 tons. And it has been able to produce cover molds for mid-range cars. The domestic stamping die industry is constantly catching up with the world's advanced level, and constantly narrowing the technological gap with the developed ones. Many domestic precision stamping dies can already be on par with imported products in terms of main performance. However, most of my country's export stamping dies are medium and low-grade products with low technical content, so the market satisfaction rate of medium dies with high technical content is lower than the overall satisfaction rate of stamping dies. The development of these dies has lagged behind the production of stamping parts. Some low-grade simple punching dies have tended to oversupply and the market competition is fierce. Stamping dies are high-quality, high-efficiency production tools. The production efficiency of stamping processing is high, the operation is convenient, and it is easy to realize mechanization and automation. Therefore, stamping dies also play an important role in manufacturing. As a big manufacturing country, my country's stamping die market continues to expand and has good development potential.With the rapid development of the national economy, the market demand for molds continues to grow. In recent years, the mold industry has been developing rapidly with a growth rate of about 15%. Among them, the overall level of the stamping die industry has been significantly improved, not only to achieve import substitution, but also a considerable part of the production is exported to the United States, Japan and other industrially developed regions and regions.Our country still needs to continue to adjust and optimize the market pattern of stamping dies. Domestic enterprises should pay attention to the importance of product quality, cost and the ability to develop new products. In the future, the precision of stamping dies will be higher, and cad/cam/cae technology will be fully promoted. With the development and progress of microcomputer software, the conditions for popularizing cad/cam/cae technology have been basically mature, and high-quality steel will be selected and the corresponding surface will be applied. Processing technology to improve the life of the mold. Only in this way can we continuously increase our high-end market share.
What should I pay attention to when choosing a torsion spring?
2026-03-07
The torsion spring is an indispensable coil spring in the mechanical and electronic industries. The torsion spring can store and release angular energy or statically fix a device by rotating the force arm around the central axis of the spring body. The ends of the torsion spring are fastened to other components, and as the other components rotate about the center of the spring, the spring pulls them back to their original position, generating a torque or rotational force.What should be paid attention to in the configuration of the torsion spring? A torsion spring is designed with its coils in close contact with the intent of promoting rotation and allowing it to generate an angular return force. There are several options for lever configuration, which can hold the spring in different ways. For torsion springs, the arm specifications that must be considered include arm angle, equal arm length, and arm closure type. When the springs are straight or parallel on the same side, the arm angle is considered 0° and the angle increases along the non-rotational direction. Types of arm closures include straight twist, linear offset, hinged, short hook closures and hook closures. To satisfy the application rules, you can twist, twist the end of the torsion spring, or make it a hook or loop.2. What parameters must be paid attention to when choosing a torsion spring?1. The thickness of the spring wire should be selected according to the size of all necessary spring elastic forces. Generally represented by the letter d.2. It is also necessary to understand the diameter of the cross-section of the torsion spring.3. The natural length of the torsion spring and the maximum torsion angle of the torsion spring. Only by calculating the maximum force that the torsion spring can support can the service life of the torsion spring be extended.4. It is also necessary to understand the maximum load of different torsion springs, and then you can choose the spring according to your own needs. Metal extension spring5. Special attention should be paid to the spiral direction of the spring. This is the most common mistake area in our daily life. People often misremember the direction of rotation. So it is necessary to keep this in mind.

Hilift Drum refers to a wire sheave that contains both a flat sheave part and a tower sheave part. At a certain width, the radius does not change, and at other widths the radius is gradually increased. Similarly, if the load is constant, the moment on the axis of the reel does not change in the flat wheel part, but gradually increases in the tower wheel part. This kind of reel is generally used for high lift.
