Common types of EBM equipment.
Continuous and Intermittent EBM are two most common variation of EBM. While shuttle type and rotary wheel type machine are more common seen types of machine belong to continuous EBM. Accumulator head machinery is the common type of intermittent EBM.
1. Shuttle blow molding machine:
shuttle machines are most used by factories in European, Latin American, Asian areas. They can be either single-sided or dual-sided machines(equipped with two sets of molding). The bottle parison extruded by flowhead constantly in middle of equipment, then mold move to the position where parison is, mold close and move back where blow pin is ready to blow air into mold cavity and start forming semi-product designed. Shuttle machines usually are used to produce calibrated neck bottles(smooth inner wall of bottle neck).
2. Rotary wheel blow molding systems
Rotary wheel machines are more popular in North American factories. They are used for high-output production of a wide variety of plastic extrusion blow molded articles. Containers may be produced from small, single serve bottles to large containers up to 20-30 liters in volume – but wheel machines are often sized for the volume and dimensional demands of a specific container, and are typically dedicated to a narrow range of bottle sizes once built.
Rotary wheels, which may contain from six to thirty molds, feature continuously extruded parisons. Revolving sets of blow molds capture the parison or parisons as they pass over the extrusion head. The revolving sets of molds are located on clamp “stations”.
Most Rotary wheel machines is unable to produce calibrated neck finish bottles.
