“…Further improvements in the mechanical properties of the SRM with CCC by adding fillers or reinforcing additives, such as wollastonite, glass fibers, carbon fibers, glass sphere, molybdenum disulfide [ 66 , 67 , 68 , 69 ], zirconia [ 70 , 71 , 72 ], silica sand, or silicon nitride [ 73 , 74 , 75 ] into the SRB is also an important research issue. In addition, the internal surface of CCC has high surface roughness [ 76 , 77 , 78 ] and result in reduction in mold life due to stress concentration [ 79 , 80 , 81 , 82 ]. Thus, surface improvement of the CCC by abrasive flow machining [ 83 ], electrochemical polishing [ 84 ], chemical polishing [ 85 ], laser polishing [ 86 ], ultrasonic cavitation abrasive finishing [ 87 ], or abrasive blasting [ 88 ] is also an important research topic.…”

Silicone rubber mold (SRM) is capable of reducing the cost and time in a new product development phase and has many applications for the pilot runs. Unfortunately, the SRM after injection molding has a poor cooling efficiency due to its low thermal conductivity. To improve the cooling efficiency, the thermal conductivity of the SRM was improved by adding fillers into the SRM. An optimal recipe for fabricating a high cooling efficiency low-pressure injection mold with conformal cooling channel fabricated by fused deposition modeling technology was proposed and implemented. This study proposes a recipe combining 52.6 wt.% aluminum powder, 5.3 wt.% graphite powder, and 42.1 wt.% liquid silicon rubber can be used to make SRM with excellent cooling efficiency. The price–performance ratio of this SRM made by the proposed recipe is around 55. The thermal conductivity of the SRM made by the proposed recipe can be increased by up to 77.6% compared with convention SRM. In addition, the actual cooling time of the injection molded product can be shortened up to 69.1% compared with the conventional SRM. The actual cooling time obtained by the experiment is in good agreement with the simulation results with the relative error rate about 20%.

Nickel-based single crystal superalloy has no grain boundary and excellent high-temperature performance. The traditional grinding mechanism of shearing and slipping along the polycrystalline material's grain boundary based on the theory of elastic-plastic deformation is not suitable for grinding single crystal parts. At present, there are few studies on microgrinding nickel-based single crystal superalloy. The grinding quality directly affects the workpiece's service life. To realize highquality and low-damage grinding nickel-based single crystal superalloy (001) crystal plane, this paper studied the surface roughness and the wear of the microgrinding tool. Firstly, it was assumed that the protrusion height of the electroplated abrasives on the grinding tool obeyed Rayleigh distribution. Based on the cutting state of abrasives, the prediction model of surface roughness of microgrinding nickel-based single crystal superalloy was established and verified by experiments. Secondly, the effect of grinding parameters on microgrinding surface roughness was analyzed through a single-factor experiment. Finally, the main wear forms, wear mechanism of grinding tool and the influence of grinding parameters on wear of grinding tool were analyzed. The results showed: although there was some error between the predicted value and the experimental value, the predicted value of the roughness and the experimental value had the same trend with the change of microgrinding parameters; with the increase in spindle speed (n g ) and the decrease in grinding depth (a p ), the surface roughness of microgrinding nickel-based single crystal superalloy showed a decreasing trend; with the increase in feeding rate (v w ), the surface roughness increased obviously; the wear of the grinding tool could be divided into five forms; the diameter of the microgrinding tool showed a trend of rapid reduction, then steady reduction, and finally rapid reduction under all grinding parameters. This study provided an important theoretical and practical reference for the manufacturing of nickel-based single crystal superalloy microparts.
