The panel molding material is polypropylene (PP) and its grade is FR-PPV7000.
The lowest material molding temperature of PP is 220°C and the highest temperature is 260°C, so the recommended temperature is 240°C.
The external heating hot runner plate transmits the plastic melt to the hotnozzle from main channel nozzle across subchannels to ensure the temperature of the melting material.

Genetic Algorithm and its Application in Optimization of Frequency Selective Surface Jingyu Han1,a , Qun Wang 2,b , Chuanyou Lic , Zhanghong Tang, Meiwu Shi 1 College of Material Science and Engineering, Beijing University of Technology, Beijing, 100124, China 2 The Quartemaster Equipment Research Institute of the General Logistics Department of the PLA, Beijing, 100088, china a hanjingyu@emails.bjut.edu.cn, bwangq@bjut.edu.cn, clichuanyou111@emails.bjut.edu.cn Keywords: genetic algorithm, periodic structure, frequency selective surface, reflection Abstract.
The periodic structure is applied in many fields such as absorbing material, radar cross section, sub-reflector and so on [2].
All of this is because of the copper plated on the fabric is oxidized, the conductivity of the material was changed, and the size of the structure with the error.

At this point from equation (3) can be introduced: (4) When the stress circle move to the left until stress circle and envelope are tangent, the material has reached the limit state of shear failure.
Then deformation state and actual situation are compared to verify the correctness of research method, calculation model and material parameters.
In order to reach good effect, the design volume of the filling material is 70000 m3 considering the high fluidity of grout.
