The Impact of Profile Mold Squeezing Method-WJW Aluminum Supplier Aluminum

The impact of the profile mold squeeze out of the aluminum material

The aluminum -type squeezing mold is pivotal in the extrusion process of aluminum profiles. It is a basic information tool that guarantees the company's products and enables it to develop a correct shape, size and accuracy. The K value of the heat conduction coefficients of doors and windows such as aluminum doors and windows is below 3W/m2 · k, which is reduced by half compared to ordinary doors and windows, reduced the heating cost of about 30%, and the sound insulation is more than 29 decibels. National A1 -class window standard. The curtain wall is the outer wall of the building. It is hung up like a curtain, so it is also called a suspension wall. It is a lightweight wall commonly used in modern large and high -rise buildings. The structured enclosure structure consisting of the structural frame and inlaid plate does not bear the main structure load and function of the main structure. Aluminum profiles are coating technology. It adds pre -plating and electroplating process steps on the basis of conventional titanium plating process. The pre -plating process is to place the activated plating parts in the water solution of salt and hydrochloride for chemical treatment. In actual production, we may lead to some problems in the process of squeezing.

i. The impact of the seam angle or poor welding:

The hollow aluminum profile adopts a plane diversion combination squeeze and forming, making it more difficult for the production of profile. Metals form welded seams by diversion welding.

There are two reasons for the slice: one hole, in the small solder, the metal flow is not enough to make the metal instead of sufficient fluid static pressure in the welding room. The existence gap;

Second, the effect of excessive lubrication and adverse effects caused by poor welding behavior of hollow profile.

Second, the aluminum material wall due to the concave or bow -shaped convex surface

1. The hollow aluminum profile export material wall under the wall of the concave bow -shaped surface produces important reasons: the aluminum -type material model workers are lower than that of the lower mold pores, and the effective data of the molding workband is caused by short length of time.

2. The reasons for the protruding wall of the hollow aluminum material: the mold has been used for too long, the core workband is severely worn, the groove occurs, the friction resistance occurs, and the slow metal flow causes the hollow material wall to protrude .

Aluminum profile surface stripe

The outer surface of the stripes of the profile, and after more obvious anode oxidation. The large contour thickness part of the defect shared on the back surface on the inner side and welded the metal diversion bridge and branches on the threaded hole.

cause:

1. The profile and the inner branches and threaded holes due to insufficient metal supply or excessive use caused the cell surface for stripes;

2. The surface contour molding part of the stripes caused by the junction area caused by the diversion bridge;

3. The problems existing in the design process of the profile section. Due to the large wall thickness difference between the various profiles, the part of the workband length occurs at the partialization of a barrier after the anode.

4. Due to the insufficient cooling capacity of the machine, the anode oxidation black stripe area is caused;

5. The quality of the blank itself is not good, which affects the color difference of the stripes after the anode oxidation of the material.

Fourth, unreasonable ways of bending and twisting of aluminum alloy profiles:

1. The workband of the mold and the lower mold hole is unreasonable, causing uneven distribution of metal surface flow rates in each part of the profile;

As shown in Figure 2, the segmented symmetrical hollow mold pore pore diameter and processing non -known position, the supply of metal current is uneven, resulting in uneven metal flow;

3. Irregular diversion processing or a hindered in the mold hinders hindering the flow of Chinese metal enterprises.

Amendment method:

1. Use appropriate methods to grind the exit part of the molding core or diverthole, and appropriately expand these diversion holes if necessary;

2. Use sandpaper to remove obstacles
