A plastic blow molding system and a method for blow molding utilize an in-mold labeler and a method for in-mold labeling a rotary plastic blow molding machine includes a dispensing assembly having a dispensing wheel that is rotatably mounted on a base and supports a plurality of dispensing head assemblies each of which includes a support and a dispensing head. Further a thin dielectric cap is formed over the metal blanket film. A volute spring disposed between a rear wall of the lock block and a cavity in the buttstock is adapted to rearwardly bias the buttstock towards a fully extended position. The semiconductor material is then etched through the hole array of the etch mask to produce holes in the semiconductor material and thereafter applying a passivation layer to surfaces of the holes.
