Aluminium plate in the contemporary industrial production is extremely common, has become a lot of industry is very important material, in the use of aluminium in the process some people found that some of the strength of the alu
minium plate can not meet the needs of the phenomenon, and even crisp, which are the reasons , But also through which channels to deal with it, haomei aluminium as a leading international supplier of aluminium for everyone to interpret.
1, for the convergence caused by the poor convergence of the bar should be appropriate to increase the ribs and the outer surface, tendons and tendons at the convergence of the length, or increase the compression ratio to solve the change in die pressure can be changed by changing the length of the straight section To adjust the flow resistance.
2, the cooling rate of the mold, the cooling water temperature is often not enough attention, the role of cooling water is the stretch of the macromolecules in a timely manner cooling stereotypes to achieve the purpose of use.
3, in the mold design stage can choose a different compression ratio to change the extrusion pressure, but must pay attention to the head compression ratio and the extruder screw compression ratio to adapt; can also change the formula, adjust the extrusion process parameters, increase Porous plate to change the size of the melt pressure.
4, the mold cross-section design is unreasonable, especially the distribution of the inner ribs and the interface angle of the treatment, this will cause stress concentration phenomenon exists, the need to improve the design and elimination of the interface of the right angle and acute angle.
5, die output is not uniform, resulting in uneven thickness of the profile wall, or the density is inconsistent. Which also caused the profile between the two aspects of the mechanical properties of the difference, as the wall and other non-standard profile here no longer say.
6, die pressure is insufficient, the pressure at the die is directly by the mold compression ratio, in particular, the length of the mold to determine the length of the straight. The compression ratio of the die is too small or the straight section is too short to cause the product to be not dense and affect the physical properties.
In fact, as a user, the surface of some of the most simple way to find the problem is to find such a high-quality
aluminium foil suppliers, because many small factories in the production process is difficult to achieve high requirements, the production of products problems Is very common. If you still have questions, you can consult the technical staff of haomei aluminium. Welcome to visit
