The used blow molders that SMB carries are generally PET Plastic bottle blow molders. These machines take a preformed piece of injection molded polyethylene terephthalate plastic, heat it and blow it to the extents of shell or mold to form a bottle. Blow molders can be used to save money by producing your own empty bottles in house as opposed to buying from a supplier. Buying one used from SMB can lead to even greater savings. SMB also carries the equipment to support your blow molding operation. – We are here for all of your used packaging and process equipment needs.
