With finite element analysis software Moldflow  numerical simulation and studies about FM truck roof handle were conducted on gas-assisted injection molding process. The influences of melt pre-injection shot  gas pressure  delay time and melt temperature were observed by using multi-factor orthogonal experimental method. According to the analysis of the factors' impact on evaluation index  the optimized parameter combination is obtained. Therefore the optimization design of technological parameters is done. The results show that during the gas-assisted injection molding  optimum pre-injection shot is 94%  gas pressure is 15MPa  delay time is 0.5s  melt temperature is 240 C. This study provided a more practical approach for the gas-assisted injection molding process optimization.

The design method and result are described for an infrared afocal zoom system. Its zoom ratio is 4  (2) Functions such as changing the field-of-view  and the corresponding field of view is 3-12. The working waveband is from 7.5m to 10.5m  focusing for objects at finite distances and athermalizing the system can be achieved by axially moving a single element in the system.  and its total length is required to be no more than 350mm. The final optical system consists of 7 elements  with aspheric surfaces and a diffractive optical element. It achieves diffraction-limited imaging at the far infrared waveband. Two conclusions can be drawn from the design. (1) Using diffractive optical elements in the design of an infrared optical system is an effective approach to control color aberrations  which eliminates the need to use exotic and expensive materials and helps to reduce the cost of the system
