Industry 4.0 mainly emphasizes industrialization. If a product wants to realize its industrialization, then its premise must be standardized.

Industry formats and trends

In recent years, there have been signs of gradual reduction in real estate investment, so the sales of doors and windows in the future may shift from new buildings to renovation of existing buildings. This renovation includes not only the renovation of doors and windows, but also the renovation of existing building curtain walls. Future orders will not necessarily come from large-scale construction projects of 100,000 square meters or hundreds of thousands of square meters, but will come from one building to another.

Projects come one by one, leading to a trend that our industry enterprises will face - fragmentation of orders. This trend will put forward new requirements for the processing and production of doors and windows, and doors and windows enterprises must consider how to adapt to the changes in this demand. At present, many domestic enterprises, including aluminum profile enterprises and door and window enterprises, are increasing investment in all aspects, that is, product series research and development and product series integration within the enterprise system, forming an integrated, multi-series of systematic products . In this system, the standardization of accessories is realized, and various accessories are formed, including parts, hardware, glass, profiles, sealing and other aspects, and even the integration of the entire system. Enterprises have begun to emphasize the integrity and rigor of the entire system design in design, emphasizing the versatility and interchangeability of internal parts of the product.

In the curtain wall industry, the current standardization is slightly weaker, and the door and window industry has gone fast, which has been changed by the systematization of the industry. The standardization degree of many foreign curtain wall enterprises in the curtain wall system is close to 70%. In China, such as China Construction Curtain Wall, they are now vigorously promoting internal standardization, and I believe they have reached this level. This is a necessary prerequisite for the realization of industrialization, automation and informatization in the future. We have also seen many automated production enterprises, and the level of standardization within the system is indeed very high.

Systematic product design

In the 40 years of reform and opening up, our consumer demand and product quality have indeed continued to improve. The core of this improvement is the improvement of quality. Driven by the improvement of quality demand in my country, some door and window enterprises have begun to develop towards product systematization and systematic design. At least the mainstream and large-scale enterprises in the domestic door and window industry have begun to design systematic doors and windows.

Due to the gradual shrinking of the market cake and these design changes, the competition situation of the entire industry and the entire competition pattern will change in the future, and market integration and enterprise integration will occur. The way of integration includes the integration between door and window factories and door and window profile companies in the industry, as well as the integration outside the industry, such as the integration between glass companies and door and window companies. At present, there has been a momentum of cross-integration between several industries.

Many companies in the door and window industry are increasing product research and development, or setting up special research and development departments, and some special door and window system companies have emerged in China. At the Doors and Windows Expo in Guangzhou last year, we can see that the door and window system companies are very popular at the exhibition, and there are even claims that the system doors and windows are southern and northern; many foreign system companies have also entered China.

Customers pursue quality

In the face of changes in the entire industry market, door and window products have already seen some differences in levels. For example, in the central city market, due to the improvement of the economic level and the improvement of the consumption concept, the requirements for product quality are stronger; in the rural and small town market, although the market volume is larger than that of the central city, this market is still low-end. The market is full of products with small profits. The demand for price in this market is still very strong. Their demand for quality is still not at a higher level. It is still at the low price and low quality from 2000 to 2006. A state of competition, a state of vicious competition.

Since the door and window association proposed the development of system doors and windows and industry certification in 2014, we have clearly felt that the overall development situation of the door and window industry is changing. In the future, in the door and window industry, driving product design, market driving and sales, a perfect product is the customer final demand. Although it is said that there are differences between the south and the north in the door and window system, the final result will be the same. No matter which system door and window company it is, the quality of the product must be the first consideration of the customer, which is the brand recognition of the product and the product. value expression.

System doors and windows are not necessarily high-priced doors and windows, but must be the most adaptable doors and windows. China has now begun to propose that doors and windows should have a service life of 25 or even 50 years. The service life of European doors and windows is clearly required to be 25 years, and the minimum requirement is 25 years. If all our doors and windows require a 25-year service life, how many doors and windows can meet this demand? How many of our system doors and windows can meet this requirement? Now we don't necessarily know what to expect.

The final requirement of perfect products for customer needs is quality service. Many system companies that entered China in the early days are very famous in China, but their sales volume is not necessarily large. The main problem lies in the response speed of serving customers. They are limited by distance and supply chain conditions, and customer service is limited. Can't keep up with the speed.

Rationalization of business management

Making doors and windows is to integrate N kinds of materials, but how to integrate? Why do others integrate well, but you do not integrate well? This involves many factors such as material, structure, structure, etc. Without a certain technical level, it is really difficult to make doors and windows well.

The future development of products in the door and window industry must be determined by ideas, not necessarily by technology. That is to say, your judgment on future development determines whether you can seize the market opportunities.

To make energy-saving doors and windows, it is necessary to clarify the business ideas. The first is that the target market positioning must be clear. If you are not clear, you will not be able to meet the needs of the market in the subsequent market changes. In terms of market positioning, there was a so-called foreign system company that entered China at the earliest time, and finally blossomed everywhere, forming a vicious competition among real estate developers. This competition led to this product, including the entire brand. Rapid decline in the trend of the development of the entire industry.

Then there is the brand, the brand is the accumulation of product reputation, and it is also the most effective strategy for products to occupy the market and improve product revenue.

Finally, there is the mode of cooperation. We have seen too many companies in China, be it door and window companies, glass companies, upstream and downstream, or the supply chain between the entire supporting material companies. Played all over the place. I used this company's product today, and tomorrow another company said, I can give you some money and I'll change it right away. This situation rarely occurs in advanced countries. Changes in his supply chain must be systematic changes, which means that his supplier strategy has changed as a whole.

The impact of Industry 4.0 on the door and window industry

Industry 4.0 is a networking of interactive production technologies, from production all the way to the delivery of the final product, a physical fusion. The level of Industry 4.0 in China's pharmaceutical industry and automobile industry is already very high. In the door and window industry, only a few companies are doing well. In this regard, the speed of foreign development, especially the German door and window companies in the field of Industry 4.0, is indeed faster than ours. We saw a production line with an annual output of 900,000 doors and windows, and there are seven people in the glass making part. There are no people on the production line, all equipment and automated production.

The door and window industry is still in the era of Industry 3.0, the difference between the era of Industry 4.0 and the era of Industry 3.0: the era of 3.0 pays attention to the assembly line process, sequential operation, centralized control, wired communication, and cannot monitor the location information of products in real time; the era of 4.0 emphasizes the unit The process of self-discipline operation of each unit, decentralized control, wireless communication, and real-time monitoring of product location information can realize the integration between various devices. The era of Industry 3.0 emphasizes a single type of mass production. For example, we take construction projects as the sales target, and the supply of doors and windows is the same as a single type of large-scale, mass production of a single project.

But in the era of Industry 4.0, one of the features it embodies is the simultaneous mass production of multiple species. In the management concept of doors and windows, the 3.0 era is product-centric, and the 4.0 era is customer-centric; the 3.0 era emphasizes low cost, and the 4.0 era emphasizes rapid market response. In the driving mode: 3.0 is guided by market forecasts: production is planned based on system forecasts such as sales forecasts and production capacity forecasts; in the 4.0 era, fixed-point arrangements are made according to customer orders. The 3.0 era considers the stable control of mass production, and the 4.0 era mainly considers the flexibility of production. The final strategy, one is the concept of cost, the other is differentiation and quick response, which is the same in the door and window industry.

In China's door and window market, the first consideration at present is cost, and developers want the lowest price. But the future really comes to the 4.0 era. When you go to the home improvement market, although the price is still one of the factors, the core is not here. Now many door and window system companies or door and window factories process products, from measurement to product supply and installation, the time given is at least 17 or 18 days, 20 days, and a longer one and a half months; if foreign systems are used, Even if it takes more than two months, it is difficult for customers to accept such a supply method.

The changes that Industry 4.0 has actually brought to our industry are believed to have three aspects, all of which are closely related to our industry.

Intelligent change

Intelligent changes include intelligent factories, intelligent production, and intelligent logistics.

smart factory

In the future of intelligent factories, the operating system will have autonomous capabilities, which can collect and understand information from the outside world and itself, and can analyze, judge and plan its own behavior. The intelligent factory will use visual technology as a whole, combining signal processing technology, reasoning and prediction technology, simulation technology and multimedia technology to demonstrate realistic design and manufacturing. Various software used in smart products, smart tools and means of production will be common in the global smart supply chain.

intelligent production

Intelligent production includes several major elements: one is Manufacturing Execution System (MES), the other is Distributed Control System (DCS), the third is Product Life Cycle Management (PLM), and the fourth is Enterprise Resource Planning system (EPR), and fifth is the supply chain management system (SCM).

When the number of fragmented orders is large, how to coordinate equipment and production capacity for production planning and raw material organization, this kind of intelligent production of door and window factories will greatly improve the production capacity and product quality of enterprises. It is very likely that without the conditions for intelligent production, companies cannot cope with this situation of fragmented orders, or at least their competitiveness is greatly lacking.

intelligent logistics

Intelligent logistics means that advanced Internet of Things technologies such as barcodes, radio frequency identification technology, sensors, and global positioning systems are widely used in product warehousing, packaging, distribution, transportation, loading and unloading and other production activities through information processing technology and network communication technology platforms. , to realize the automatic management of the cargo transportation process, improve the service level of product logistics, reduce costs and reduce resource consumption.

In terms of intelligent logistics, many factories in China have already used QR codes in the process of delivering various components. However, although some companies put QR codes on product components for each production link to identify each production link, but In the end, it was found that the central control system and the entire remote end were not actually networked, so the product barcode technology was still in a semi-finished state. Intelligent logistics is very important. In the future, if our logistics system cannot keep up, it will be difficult for the entire enterprise to meet the demand in terms of response speed.

software revolution

Industry 4.0 will bring about software changes that will have a greater impact on product design, production planning, production processes and production services. CAD, which is widely used in design, is mainly used in drawing. In recent years, BIM technology has been developed for design, planning, engineering, production and implementation.

The impact of software change on product design is mainly to shorten the product development cycle. With the emergence of 3D technology and the improvement of design software, product development can be virtualized through design software, 3D technology, and on-site simulation technology, and various problems that will arise can be solved through virtual means to achieve rapid verification and rapid production. In the retail sector, VR and AR technologies have been used to solve some problems in door and window design.

VR and AR technology, also known as on-site simulation, wearing Google's special glasses, you can directly see how your windows are designed, how to divide, what color, and you can adjust the design plan on the spot, finalize it on the spot, and directly process it. Greatly improve delivery speed.

Now because of the requirements of the Ministry of Housing and Urban-Rural Development, the application of BIM in curtain wall design is almost useless in the door and window industry. However, the 3D software in the door and window industry is based on CAD technology. With 3D technology, there are not only plane effects, but also three-dimensional effects. The use of several product design software can accelerate product development, shorten production cycles, reduce engineering costs, and improve services. quality.

The impact of software on production planning is mainly to use product life cycle management software (PLM), combined with automation software and motion control software (MCS), to conduct virtual simulation research in the planning stage to improve the implementability and effectiveness of planning.

The impact of software on production implementation is mainly the optimization of the production chain. Software can optimize the production chain of product design, production planning and production engineering, improve efficiency and quality, and make the production process more efficient with less effort. By running the Manufacturing Execution System （MES） the high efficiency of production can be ensured; through data fusion, all production management processes can be made transparent, and real-time interaction can be achieved at all stages and links of the process; production implements this set of systems, including production, design , manufacturing, can ensure the consistency of the entire product production quality and high production efficiency.

The weakest equipment link of an enterprise often determines the most important overall production capacity. The manufacturing system MES can distribute the production plan to the equipment level through the manufacturing system and balance the production capacity. Once a problem occurs in a certain equipment, how to quickly balance the integrity of the entire system will be a very important issue in the future. Through the control of this software, the use of manual labor can be greatly reduced and the efficiency of equipment use can be improved. In China, some enterprises have already installed MES equipment, from automatic cloth supply, to coordination between different equipment and different parts of equipment, to the final output of products, realizing the whole process identification from semi-finished products to finished products. Three companies in the glass industry have done it, but the door and window industry has not.

Changes in business models

The transformation of the business model is mainly reflected in the transformation of the organizational structure and functions of the enterprise, the transformation of the enterprise operation management mode, the transformation of the enterprise marketing form, the transformation of the enterprise resource management and the transformation of the industry format.

In terms of organizational structure and functions, parallel work and joint work will coexist, and it will be a cross-functional, cross-departmental, and cross-disciplinary organizational form.

It turns out that many companies are a radish and a pit, and there is no exchange relationship between positions. After the change occurs, it may be a turnip and several pits, and the skills of positions and personnel must be multi-faceted. If people who are engaged in technology in the future are not familiar with customers, and are not familiar with the market and needs, you will end up drawing for others. If technicians can't face the changing market demands and the technology can't be close to the market, your technology will be useless, you can only be a draughtsman.

In terms of the organizational structure of the enterprise, there will be a coexistence relationship between our system company and the supporting material suppliers, and there will also be such a cross-departmental and cross-system organization among the personnel within the system company.

In terms of operation mode, the future business model under the conditions of Industry 4.0 will be digital, production will be planned, customer response will be agile, manufacturing will have certain flexibility,
