• Increase the cross-sectional area of the sprue, runner, and gate
• Also shorten the length, smooth the surface
• Provide sufficient gas venting to the sprue and runner
• Add sufficient air bleeding to the mold
• Degas the mold
• Move the gate position so that welds will occur in places with a low load

• Increase injection pressure
• Increase cylinder temperature
• Increase mold temperature
• Increasethe injection speed
• (increasing the temperature at which the split resins merge and fuse)

By adding the vent function, the air resistance in the mold is eliminated and the internal pressure is reduced.

Degas is just below the sprue part and at the runner end. Increase the air vent near the final filling part of the product part.

By taking good venting measures with the mold, there is no air resistance in the mold and molding at low pressure is possible.
