Ensure that the vacuum level reaches the standard, the vacuuming time is sufficient, and the air in the mold cavity and material liquid is completely discharged.
Control the pouring speed and flow channel design to avoid bubbles being trapped in when the flow rate is too fast
Reasonably set the curing temperature rise curve to prevent internal volatile gases from being discharged
Mold exhaust slots and exhaust holes are opened in place to discharge residual gas in the cavity in a timely manner.
Mix the raw material proportions evenly to reduce air entrainment during the mixing process.
