The pellets are then heated and melted inside the cylinder in preparation for injection. The material is then forced through the nozzle of the injection unit before being delivered through a channel in the mold called a sprue and then through branched runners into the mold cavity. After the ...
How Do PCPs Fire Pellets? Once the trigger is squeezed it opens a valve and a small amount of compressed air is released. This air pushes the pellet up through the barrel and out of the gun. Each shot uses up the compressed air, which gradually reduces pressure and the amount of air ...

3ScrewTransports the pellets through the barrel, heating them to create a homogenous melt, a process termed plastication. 4NozzleOnce the injection unit (1) produces an adequate amount of melted plastic, the reciprocating action of the screw (3) injects the melted plastic through the nozzle int...
A learningalgorithmplayingPac-Manmight be able to move in one of four possible directions -- up, down, left and right -- barring obstruction. From pixel data, an agent might be given a numeric reward for the result of a unit of travel: 0 for empty spaces, 1 for pellets, 2 for fruit...
