The test pieces are all made by injecting pre dried particles (with a moisture content of less than 0.02%), and after injection, they need to be annealed at 100 ° C for 20 hours.

The test spline is made by cutting the test piece. Test environment: Room temperature 23 ° C ± 2 ° C, air humidity 50% ± 6%.
