Factors affecting the purchasing power of the tool industry

In recent years, with the development of the mold manufacturing industry, the requirements of the mold component materials themselves have increased, and superhard tool materials such as CBN (cubic boron nitride), PCD (polycrystalline diamond) tools and new cemented carbide tools have been widely used. The consumption and purchase of tools has become a topic of common concern for mold manufacturers and tool manufacturers. Application of integrated tools Among the tool materials selected by domestic mold users, the most used carbide tools are 64.1%. With the development of superhard tools, hard turning is becoming popular as an economical alternative to grinding. The use rate of super-hard tools has been significantly improved. For example, the machining of cylinder bores has adopted cubic boron nitride inserts in the semi-finishing and finishing processes. The cutting speed has reached a new height and the tool life has been greatly extended. The indexable tool has been promoted in China for many years and is progressing smoothly, but the development is still unbalanced, and the user coverage is still lower than the overall tool and welding tool. However, the technology of indexable cutting tools in China has made new progress in the process of promotion, and the application potential of rapid increase in variety is great. The machining of modern mold manufacturing and the tool technology used in it have developed rapidly. High-tech is widely used. In the aspects of machining technology, cutting method, tool structure, tool material, tool coating, etc. The difference. New tool structures and inserts with new cutting edges and geometries have been continuously researched and developed to accommodate tool holders for CNC machine tools and high-speed machining and their connection to machine tools such as HSK tool holders, hot-sleeve holders, hydraulics Tool holders and other new tool holders are widely used. In order to improve production efficiency and reduce tool change time, various composite tools, such as drill collar compound, drill hinge compound, drilling and thread processing compound, are used more and more in the processing of mold parts. The unfolding tool meets many special machining requirements, and some tools have even evolved into a machine, electric and hydraulic integrated device, which has far surpassed the traditional tool concept. Tool consumption characteristics of the mold industry In order to achieve lean production of molds, mold companies scientifically organize the procurement and inventory management of tools, and need to study and explore how to reduce the inventory capital of the tools and optimize the minimum inventory setting of the tools while ensuring the normal operation of the production line. , the procurement starting point of the tool, the reasonable procurement frequency of the tool and the purchase batch, establish an effective tool early warning mechanism, emergency mechanism and quick response mechanism, and have a scientific and effective method to track and monitor the tool inventory status and purchasing status. It is understood that 68.5% of the user's enterprise tool costs account for less than 3% of the total cost, and the manufacturing cost of manufacturing tools in developed countries accounts for about 4% of the production cost, which is also a low level of manufacturing in China. A factor. China's mold industry is related to the phenomenon of decentralization, low-scale and low-level. China's mold manufacturers are a few large-scale companies, and the rest are mostly small and medium-sized. These conditions determine the characteristics of the tool industry users to use the tool: the purchase volume is increased, the number of purchases is frequent, that is, the purchase is at most two months. This aspect reflects that the consumer market is relatively mature, and the tool users in the mold industry are more inclined to make budgets. For flexibility, rather than retaining too much inventory. At the same time, due to the flexibility of user procurement, the market offers opportunities for entry to those tool suppliers that have not yet entered. Due to on-demand procurement, the competitiveness of the replacement of used brands is also increasing. Factors Affecting Tool Purchasing Power Users pay more attention to efficiency improvement and input-output ratio optimization rather than focusing on pure price factors. The connotation of "service" has been developed from pure pre-sales and after-sales service to the solution of cutting solutions. The performance and quality of the tool directly affects whether the required qualified product can be smoothly processed. Whether the tool can meet the requirements of high-speed cutting, how the tool life and the frequency of the tool change directly affect the starting rate of the production line, affecting the processing cycle and production efficiency. The ability to provide adjusted or repaired tools to the production line on time and with guaranteed quality will directly affect whether production can continue normally. Therefore, the tool users in the mold industry mainly consider the use of tools: the cutting efficiency is the most important, followed by the service life. The service factor is paid more attention. The tool manufacturer also introduces various measures to complete the production together with the knife-making enterprises.

Sandwich Panel

What are the methods for judging the pros and cons of sandwich panel?
The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?

check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.

Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.


Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.

certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.

Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
