Casting Method
PT: Normal casting, cavities are located under the casting scar
QX: Oriented casting, cavities are located at the rear bottom side
ZWS: Reinforced casting, with little cavities which located at the bottom of block
WS: Total filling, no cavity since the cavity zone be cut off
There still have other casting methods like RX, RL, RA, etc. Huachen only chose the most proper for his clients.
