Recent development characteristics and trends of China's mold industry
An electrostatic spray gun is a type of device used for applying a coating, such as paint or powder, to a surface. It operates by charging the particles of the coating material with a negative or positive electric charge, which then attract to the opposite charge of the surface being coated. In this article, we will explore what electrostatic spray guns are, how they work, and why they are important.
What is an electrostatic spray gun?
An electrostatic spray gun is a tool used to apply a charged coating to a surface by utilizing the principles of electrostatics. By imparting a charge to the coating material as it is sprayed, the particles of the coating become attracted to the surface of the object being sprayed, creating an even, uniform coating.
How do electrostatic spray guns work?
Electrostatic spray guns operate based on the principles of electrostatics, which states that particles that have the same charge will repel each other, while particles with opposite charges will attract. The electrostatic spray gun charges the paint, powder or other coating material with a negative or positive charge as it exits the nozzle, creating a fine spray of charged particles. When these charged particles reach the surface being coated, they are naturally attracted to the opposite charge of the surface, creating an even and uniform coating.
Why are electrostatic spray guns important?
Electrostatic spray guns play a significant role in the coating industry, primarily due to the following reasons:
Increased efficiency: Electrostatic spray guns deliver a more efficient transfer of the coating material to the surface being applied, resulting in a reduction of overspray and waste.
Improved quality: The charged particles delivered by an electrostatic spray gun create an even and uniform coating, resulting in a higher quality and more professional finish.
Environmentally friendly: Electrostatic spray guns reduce the amount of coating material necessary for a project, resulting in reduced waste and environmental impact.
In summary, electrostatic spray guns are essential tools in the coating industry. They offer increased efficiency, improved quality, and environmental benefits compared to traditional spray methods. When used correctly and maintained regularly, electrostatic spray guns can provide a valuable tool for a range of coating applications.

So in the more than a year of the world financial crisis, or for a longer period of time, in addition to the amount of mold sales, what are the development characteristics and progress of our industry? I think the main points are as follows:
First, structural adjustment has achieved certain results. This is mainly manifested in three aspects: First, the effectiveness of institutional reform and mechanism transformation. At present, there are few state-owned enterprises. In terms of quantity and production and sales, they account for less than 3% of the whole industry. Shareholding, private and foreign-funded enterprises have absolute advantages. The vitality of the whole industry is further enhanced. Secondly, the proportion of high-tech medium and high-grade molds, which are mainly represented by large-scale, precise, complex and long-life molds, has been steadily increasing. Third, the market structure has been continuously improved, and emerging industries have received widespread attention. For example, in the field of new energy, medical equipment (appliances, equipment), automation, aerospace and rapid economic molds. The international market has a long history. In addition to the traditional markets of Europe, America and Southeast Asia, emerging markets such as India, Russia, Brazil, Australia, the Middle East and South Africa have begun to expand.
Second, the trend of overseas mold transfer to China's domestic market has continued to develop, driving the continuous improvement of the industry level and the rapid growth of exports. As the cost advantage of China's mold production continues to exist, on the one hand, foreign capital, as well as mold procurement, international molds are further shifting to China's domestic development. This has accelerated our progress because it is in line with international standards.
Third, the cluster production method has been further developed. As far as I know, there are more than 30 mold cities (gardens, districts, and agglomeration production bases) of different types and different forms in the country. More than half of them have formed a certain scale. In 2008, the output of the mold city has reached 270. About 100 million yuan, of which about 17 billion yuan in mold, the scale effect has been reflected. Moreover, the development of cluster production methods has made significant contributions to the development of modern manufacturing service industry and mold-based industrial chain in China's mold industry, and its significance is great. At present, the cluster production mode is still developing continuously, and the overall situation is good.
Fourth, the mold production cycle was further shortened, and the mold price continued to decline. This is really a lot of pressure for mold manufacturers, but for mold users, this is the result. At the same time, this is also the performance of the mold industry's technological progress. However, there is also a market irregularity, excessive price competition and overcapacity of low- and medium-end products, which should cause us to pay enough attention.
Regarding the level of China's mold industry, China's "Eleventh Five-Year" mold industry development plan put forward the goal of entering the advanced level of Asia by 2010.
We believe that this goal can be achieved. In terms of quantity, we are now the world's largest mold producing country. From the product level, it is a complete set of automotive molds for b-class and below grade cars and other passenger cars and commercial vehicles. It is a precision high-speed multi-station grade with an accuracy of 2μm and a life of more than 200 million times. In the mold, a single mold with a weight of more than 100 tons, a large multi-station progressive mold with a length of 6 meters, many high-level molds such as a light guide plate mold, a CD mold, and a biochip mold can be produced. However, China has a vast territory, and the level of many mold enterprises varies from place to place. The gap between them is very large. From a comprehensive level, compared with the international advanced level, there are indeed many gaps. The gap has prompted us to make further efforts. The gap has prompted us to forge ahead. Keeping moving forward to the world's mold powers will remain our goal for a long time.
Regarding the development trend of molds, we believe that this depends mainly on two aspects, namely, the development trend of various industries that molds serve, and the development trend of science and technology in the whole society and the world. And maybe.
Molds serve the parts, that is, the formed products. Therefore, the molds must take the development trend of the parts (formed products) as their own development trend, and the molds must meet their requirements. The development trend of the parts is mainly light, exquisite, fast and efficient production, low cost and high quality, each of which indicates the development trend of the mold. A brief analysis is as follows:
To be lightweight, it will increase the use of plastics and develop new materials, including various new plastics, modified plastics, metal plastics, magnesium alloys, composite materials, etc., which requires new forming processes, and thus requires a corresponding Adapted to the new mold. For example, the use of high-strength panels in automobiles is also increasingly used to reduce weight. Thermoforming of some ultra-high-strength panels and their suitable thermoforming molds have naturally become a trend.
To be exquisite, it requires a beautiful appearance and no defects inside, which requires fine, precise and high-quality molds to adapt to it. At present, we are very different in terms of refinement, and refinement is often overlooked and falls short.
Fast and efficient production, this aspect requires the mold company to shorten the mold production cycle as much as possible, and to deliver the mold to the mold user as soon as possible. On the other hand, it is more important to enable the user to use the mold you provide to produce the product quickly and efficiently. For example, multi-cavity multi-piece production, laminating molds, using hot runner technology to shorten forming time and using multi-layer composite technology, in-mold decoration technology, high-gloss non-marking injection molding technology, on-line inspection technology, multi-process composite technology, and more Multi-station technology and so on. At the same time, the intelligent shaping process also requires intelligent molds to adapt.
Low cost, which requires low-cost manufacturing and low-cost supply of molds through the design, processing and assembly of mold production. More importantly, mold users can use molds to achieve low-cost production. This puts higher demands on the mold. Mold manufacturing companies must first make the mold users make money before they can make money. In the process of requiring low cost, whether it is a mold manufacturer or a mold company, continuous improvement of management, and gradually realize information management are the common requirements of the enterprise and the direction of progress and development.
High quality, to achieve the high quality of the product, must first be the high quality of the mold, the stability of the mold must be good, to ensure the consistency of the product is also good, but also to ensure the longevity. High quality molds are related to technology.
In addition to the above, many new areas, emerging industries, new parts and individual requirements will continue to impose new requirements on molds. Therefore, the development trend itself is constantly developing.
From the perspective of technological development trends, the development trend of molds can be analyzed from the following six basic aspects:
New materials - new mold materials and new mold new processes for forming new materials for forming products - new forming technology and new technology and new technology for mold processing - technological advancement drives mold production to ultra-high speed, super precision and high automation Directional development of information technology - digital production, information management, and full use of IT technology network - dissolve and utilize the world's global network circular economy and green manufacturing use as little resources as possible to create as much value as possible, including recycling Recycling and environmental protection, not only can molds be able to do this, but also to mold users.
In addition to the above-mentioned development trends, we also believe that from the relationship with mold users, mold and mold manufacturing companies have always been relatively dependent and relatively passive, with few voices. I believe that this phenomenon should be gradually changed appropriately. This requires our mold industry to be self-reliant, and we must gradually become passive and active by fully demonstrating our own strengths and capabilities, as well as innovation and development. Before the National Day, I visited Haier Mould Company and I was deeply touched. The slogan of Haier Mould Company is "You give me a concept, I will give you a product" and "Never say no to the market." In terms of the market, they are “no internal instability, no external strengthâ€. In terms of concept, “the mold is used as a work of art†(now, the concept that the mold is a work of art created by the art has been produced by the mold. The high-tech products are replaced, but the concept of using molds as art works is not out of date, but it is a serious and dedicated performance, which should be promoted.) The goal is to become the "world's most advanced mold trial center" These are all for us to learn from. Haier Mould Co., Ltd. has also achieved modularization, parameterization, standardization of mold design, as well as specialization and standardization in production. In terms of transformation, they proposed to transform from enterprise informatization to informatization enterprise, from manufacturing to manufacturing (providing users with complete solutions) manufacturing. I think these ideas are already there. To a certain extent, it reflects the development trend of mold enterprises.
The development trend mentioned above is only a concept and something. We can continue to concret and deepen, such as cad/cae/cam integration, software integration, intelligence, networking, computer simulation technology. Further development and comprehensive application of three-dimensional design, high-speed and ultra-high-speed machining, precision and ultra-fine micro-machining and composite machining and five-axis machining, etc., are not listed one by one. In short, the development trend of mold technology is dynamic, it must constantly meet the new trend of mold users, and it is also closely related to the development of the world's science and technology. They can promote each other and complement each other. Of course, the development trend of mold technology is only one part of the whole mold, such as production organization form, market operation mode and management, etc., all have their own development trend, and it is also worth studying.
