Revo-sprue Star-shaped sprue

Cooling time in the sprue bush part can be reduced.

The inner shape was modified to be star-shaped from the usual round-shape by concavely making to be slender, so the area in the surface has become wide, and the cooling speed becomes speedy.

If you think that you would like to reduce the cycle time due to the situation by which cooling time of the sprue part is longer than the product part, this product fits into the way of thinking.
