Low-pressure perfusion molding technological characteristics

Time:2013-06-05 16:07 source: Leecheer Author: Leecheer Click:
Low-pressure molding technological characteristics is different with the traditional injection 
molding process.It not only have the physical molding curing, heat exchange process,but also
 have the chemical polymerization and crosslinking reaction process.The process is not only 
determined by the reaction kinetics and thermodynamics, also affected by physical conditions.
1)Since the material injection under low-pressure,mold filling time is longer than others.
2)After material filled, because of two-component materials polymerization and cross-linking 
reaction, will further raise the material temperature.
3)Compared with the filling slope time,the curing time is very long. During the forming process,
 material curing accounted for most of the time
4)The material after molding with thermosetting properties
5)The material injection is under the low-pressure,so it is only fit for the simple structure 
workpiece molding especially for the height smaller than the length and width simple workpiece.
