Generally speaking, the factor that affects windows and doors heat insulation basically has two points: heat radiation and heat conduction. The sunshine time is longer in summer, the sunlight penetrates the glass directly in the room. One part of the thermal radiation can be absorbed or reflected by the glass, the other part is released through the glass in the room and increase the indoor temperature constantly. It is very important to do a good shading for aluminum windows and doors . 1.Shading with curtains Choose the curtain of shading fabric, match again with shading cloth, also can have very good shading effect. But the disadvantage is indoor if longtime no have sunshine will be harmful to human health. 2.Using glass insulation film Glass insulation film is a kind of film that sticks on glass surface, this is a economical and practical method. The disadvantage is that the film use time is limited, after long time of using, maybe appear some bubbling, and rolling at

As you know, most materials may release harmful gas or toxicity against high temperature.  Fire sleeve   is very typical to work for high temperature application. So, before we decide to buy  firesleeve , is it better if we can t ell w hichever offers  a safe one? Before we go deeper for this question, I would like to introduce a certification first. We all know that European Union is leading in setting regulations and standards to protect the mankind. EN45545-2 is one of the many EU Safety Standards. What is it about? Generally speaking, EN45545-2 is a requirement for fire behavior of materials and components of railway vehicles.

Hydraulic press brake bending machine Hydraulic bender workpiece The first important thing to consider is the parts you want to purchase hydraulic press brake . The point is to buy a machine that can complete the processing task with the shortest worktable and the smallest tonnage. Carefully consider material grades as well as maximum working thickness and length. If most of the work is on 16 gauge mild steel with a maximum length of 10 feet, the free bending force need not be greater than 50 tons. However, if you are engaged in a large number of bottom die forming, perhaps a 150 ton machine tool should be considered. Assuming that the thickest material is 1/4 inch, the 10ft free bending requires 165 tons, and the bottom die bending (correcting bending) requires at least 600 tons. If most of the work pieces are 5 feet or less, the tonnage is almost halved, greatly reducing the cost of purchase.The length of the part is important to the specification of the bending machine. Bending rad
