Renamrocating Control of Plastic Aluminum Profiles! -Ruminum Profiles Supplier
Author： WJW Aluminum Window Manufacturers
With the requirements of the global low -carbon development situation, the market demand for insulation aluminum profiles is also expanding. As a mature product of insulation and energy -saving building profiles, it has gradually become one of the mainstream products in the thermal insulation aluminum profile market due to its high production efficiency and low cost. However, in the industrial production process of the enterprise, if the production process is produced according to the conventional profile control size, the injected aluminum profile, especially the aluminum profile of the flat window series, tends to be unilaterally deformed or deformed. Trends trend, deformation or scrap, how to avoid batch scrap generated due to deformation after injection of glue during production, it is necessary to return to the process and technical conditions of the entire production process, and carefully observe and analyze the types of different gumocomes. And the cross -section and discovery they have corresponding laws.
Therefore, design and pre -deformed products can be modified in advance to obtain a one -time injection molded aluminum product.
1. Technical improvement and process optimization
(1) There are three types of plastic injection boxes for the design of the rubber injection box, which are used for plastic injection and thermal insulation of aluminum profiles.
By increasing the thickness, the wall thickness of the cantilever side of different types of plastic injection can be improved. This is an effective way to solve the deformation of plastic insulation aluminum profiles, especially for thin -walled plastic injection aluminum profiles to ensure the stability of the squeezing material.
(2) Pre -deformation method This method is to maintain the deformation of closed mouth after injection. In mold design and extrusion production, the volume of deformation along the direction of the injection port in advance. During the deformation process, it should be checked before the deformation of the deformation of the cross section. The variable volume can be reasonably controlled by measured the angle or size of the opening. You can complete the processing technology of excretion of pre -deformed by repairing the mold.
If it is difficult to repair the mold to meet the technical requirements, it can be pre -deformed through the mold design. Of course, in the process of stretching and straight, the final deformation volume of pre -deformed profiles is needed according to the size changes of different profiles to ensure that the pre -deformation requirements of the final product meet the requirements.
(3) When controlling the glue process to control the teeth of the thermal injection plastic aluminum profile, please pay attention to adjust the depth of the teeth. The depth of the teeth should be controlled at about 0.3 to 0.5mm. To avoid opening the teeth too deep and excessive pressure, to prevent the outline deformation and lead to larger opening. The best environmental temperature of spray glue is 20 30 C, relative humidityIn order to solve the problem of the deformation of the thermal aluminum material injection molding, it was proposed by mold design, extrusion production, injection production control. The cantilever thickening method, pre -deformed method, and technical conditions for glue injection technology are proposed.
For production through the use of the above technical means and process technology, it can effectively eliminate and solve the deformation of aluminum products, and the product qualification rate is higher.
By using the above -mentioned valid process and technical improvement methods during the production process of thermal insulation glue, the 45 -degree corner window of the flat window series is prone to uneven angle and the connection between the central seam and the window frame. Central seam. The outer frame is not flat or difficult to lift. The problem of collapse defects has been significantly improved or eliminated.
