Aluminium Extrusion Profiles For Door And Window Ensure Product Safety And Performance
Oct 24, 2017

The mold strength is a very important problem in the die design because of the poor working conditions of the die when the Aluminium Extrusion Profiles for Door and Window. In addition to the rational placement of the mold hole, the selection of suitable mold materials, the design of reasonable mold structure and shape, the accurate calculation of extrusion pressure and check the permissible strength of each dangerous section is also very important. There are many formulae for calculating extrusion pressure, but the modified Biell forest formula still has engineering value. The upper bound method of extrusion pressure is also applicable value, and it is simple to calculate the squeeze pressure by empirical coefficient method. As for the mold strength check, should be based on the type of products, mold structure and so on respectively. General plane molds only need to check the shear strength and flexural strength, tongue mold and planar shunt mode need to check shear, bending and compressive strength, tongue and needle part also need to consider tensile strength. In recent years, the finite element method can be used to analyze the stress and check strength of the special complex molds.

Daily people in the consumption process,Aluminium Extrusion Profiles for Door and Window there will be such a consumption concept: the higher the price of goods, the better the quantity, the better the material more solid better ... Because the more materials consumed, the corresponding price will be higher, the quality of natural better. So is this understanding correct?

Aluminum alloy doors and windows usually constitute the price of three elements: profiles, window type, accessories. The wall thickness of the profile of the product price impact is not small, the thicker the profile, the higher the price. Many consumers in the purchase of aluminum alloy doors and windows, will take for granted that the thicker the thickness of aluminum, more than national standards, product quality is better, in fact not so.

Aluminum alloy doors and windows products wall thickness of the national standard is in the protection of product safety and performance of the situation,Aluminium Extrusion Profiles for Door and Window in accordance with the requirements of energy-saving and environmental protection set, not the thickness of the product profile thicker, the better the quality of products. Because too thick wall thickness, and can not guarantee the product's gas tightness, water tightness is good, product quality is high. To determine the quality of an aluminum alloy door and window products, we must consider the following aspects:

1, the rationality of profile design,

2, the tightness of the product and water tightness,

3, the product of glass, metal parts and accessories configuration.
