3D suction blow molding is known for its ability to mold automotive and appliance ducting in complex shapes with minimal trim recycling">scrap. As shown here, sports equipment is another opportunity for this technology. This paddle-ball racket was molded of a mix of nylon 66 and 6 with 18% glass. The parison for the hollow handle is wrapped in a complete 360° turn. The machine used was an ASPI model from S.T. Blow Moulding in Italy, such as was exhibited at NPE2018 in Orlando (see April NPE preview).
