Q
Elliptical Deformation of CMC Products
A
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is the key
Molds & Tooling CMCelliptical deformationsymmetric ejectionuniform coolingsetting time
Q
Twisting Deformation of CMC Products
A
Twisting deformation is caused by asymmetric cooling; symmetric cooling is the key

Q
Insufficient Roundness of CMC
A
Insufficient roundness is caused by uneven cooling; annular cooling is the key

Q
Non-Uniform Internal Density of CMC
A
Non-uniform density is caused by uneven holding; optimizing gate design is the key

Q
Insufficient Flatness of CMC
A
Insufficient flatness is caused by shrinkage differences and stress; uniform cooling and annealing are the key

Q
Internal Shrinkage Voids of CMC
A
Shrinkage voids are caused by thick-wall shrinkage and insufficient holding; extending holding is the key

Q
Poor Fatigue Resistance of CMC
A
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is the key

Q
CMC Angle Deviation
A
Angle deviation is caused by shrinkage and insufficient design compensation; pre-compensation is the key
