Research and Analysis on Competitiveness of Construction Hardware Profile Products

After more than 20 years of development, we have trained a large number of on-site technicians and industrial workers in the field of Building Materials production in China, and accumulated rich practical experience. However, it is more and more difficult to obtain the survival, development and growth of enterprises according to the traditional production technology and enterprise profits. To improve the technical added value of building Hardware Material products to improve product competitiveness, it is necessary to break through the existing technical bottlenecks, start from new product development, improve production efficiency, strengthen process technology control and improvement, so as to improve the core competitiveness of enterprises and products. Force. The specific measures are as follows: After more than 20 years of development, we have trained a large number of on-site technicians and industrial workers in the field of building profiles production in China, and accumulated rich practical experience. In order to improve the technical added value of building hardware products and improve the competitiveness of products, it is necessary to break through the existing technical bottlenecks, start with the development of new products, improve production efficiency, and strengthen process technology control and improvement. So as to improve the core competitiveness of enterprises and products. Force. Specific measures are as follows:

China's energy shortage will not ease any time soon. Therefore, the development of new products must be centered around the theme of energy saving. Aluminum doors and Windows mainly have two aspects: First, the development of broken bridge (glue) insulation window, as far as the current situation is concerned, the popularity of this window is an inevitable trend. At present, many common casement Windows and push-pull Windows, starting from improving air tightness and reducing aluminum consumption, still have a lot of room for improvement in the structure, so as to reduce the degree of hot and cold air convection and reduce production costs. For aluminum curtain wall, it is mainly Structural Parts of broken bridge (injection molding) curtain wall. Domestic curtain wall structure is relatively small in this respect.

2: Improve the design, processing and manufacturing level of the mold At present, the vast majority of domestic aluminum extrusion manufacturers use single-hole mold extrusion. For ordinary building profile products, usually single section output is large, batch production. Therefore, the conditions for the use of porous die extrusion are required. This requires the innovative awareness of mold designers and processing equipment and precision must be upgraded to a new level, so as to improve the efficiency of extrusion production. In this respect, we still lag far behind our European and American counterparts.

3: Improve the quality of aluminum rod melt Some aluminum production enterprises, due to insufficient attention to the quality of casting products, and product quality problems occur in the extrusion process, ingot quality problems often account for about 50%. Combined with the uniform flame effect, the influence of extrusion speed accounts for about 70%. According to the author's observation, the control of smelting workshop of most aluminum profile manufacturers is not ideal, the melt refining effect is poor, and how to prevent the secondary pollution of melt after furnace has not been paid attention to.

4: In the mold design, the mold material properties and surface treatment effect are optimized, the use of advanced extrusion technology, in the use of high-quality aluminum rods and rapid heating, can achieve the purpose of low temperature rapid extrusion, to ensure that when the pressure outlet temperature reaches 500℃ or more, the temperature of the rod is controlled in a relatively low temperature range.
