How to solve the problem of scratches and scratches in aluminum profiles

by:Zeyi     2021-07-16
There are two situations in which the surface of aluminum extrusion products have rough longitudinal or transverse grooves: scratches recessed from the surface are mostly caused by foreign matter stuck in the mold or rough processing at the empty knife. The other is raised scratches at the corners of the product, which are caused by cracks in the extrusion die. Lateral scratches or scratches are mainly due to the hardness of the cold bed when the product is transported from the slide out table to the finished sawing table. The protruding objects will scratch the product, and some are caused by loading and handling. Scratches are common surface defects in the extrusion process of aluminum profiles, so how to solve them?   The main elimination methods are:    1. The working belt of the extrusion die should be processed smoothly and smoothly, and the empty cutter of the extrusion die should also be processed smoothly.   2, the mold should be carefully checked when installing the mold to prevent the mold with small cracks from being used. Pay attention to the fillet radius when designing the mold.  3. Frequently check the cooling bed and the finished product storage table to prevent hard protrusions from scratching the product.   4. When loading, place a spacer that is softer than the product, and the transportation and hoisting should be stable, and the whole process should be carefully operated.
Aluminum profile manufacturers pay attention to environmental protection is the general trend
The '2015 Government Work Report' clearly pointed out: Make heavy efforts to strengthen pollution prevention and control. Promote changes in energy production and consumption patterns. Promote ecological protection and construction. This means that some factories with overcapacity, serious environmental pollution, and environmental protection will make adjustments. Therefore, it is the general trend for aluminum profile manufacturers to pay attention to environmental protection. The 'Guiding Opinions on the Development of Energy-saving and Land-Saving Residential and Public Buildings' issued by the Ministry of Construction in 2014 is undoubtedly a spring breeze blowing to the aluminum profile industry. It has spawned a large number of new technologies and new products that meet the requirements of building energy saving, and effectively promoted new buildings The development of the material industry. The use of new building materials has greatly improved the energy-saving indicators of aluminum profiles and expanded the diversity of aluminum profiles, such as aluminum profiles for doors and windows, cabinet aluminum profiles, curtain wall aluminum profiles, etc., greatly increasing the connotation and extension of aluminum profiles. Give people a refreshing sense of sight shock. The curtain wall has evolved from the original single wall to a building with a novel structure and bright facing materials, completely breaking the old faces of ordinary concrete walls, brick walls and ceramic tiles for thousands of years. This is undoubtedly a revolution in the construction industry. .   The diversity of aluminum profiles and their good environmental protection will surely become the mainstream products of building decoration materials in the future!
