The design of the aluminum castings is similar to the design of the plastic parts. Some of the design routines of the plastic parts are also applicable to the castings. 2. for aluminum alloy, the temperature and pressure of the die are much larger than that of the plastic, and it is very strict for the correctness of the design. Even if the mold material is very good, once the welding is welded, t...

HistoryThe earliest bikes were simple wooden framed push along affairs but soon the material of choice was heavy iron, which in turn was superseded by steel. In 1897 Alfred M. Reynolds took out his patent on butted steel bicycle tubes and, for steel aficionados, a frame bearing the Reynolds stamp is a must have to the present day. As early as the 1890's innovators such as the French Company Cycles...

The small gear further to think, in fact the doors and windows industry profits will have a declining trend, mainly due to raw material prices have risen, so to the doors and windows industry has brought some impact, the recent profit by the downward trend, if it is only raw material prices, companies are likely to eliminate the pressure through other ways but, really let the doors and windows is ...
