Importance of Extrusion Blow Moulding Machine in ...

Nowadays, plastic serves as a reliable and highly effective form of packaging for various industries, including the pharmaceutical sector. In this sector, two types of polymers are predominantly used: thermoplastics and thermosets.

The main difference between these two materials is that thermoplastics can be reheated and remolded, while thermosets cannot.

Thermosets are typically used for products that require high structural integrity and heat resistance, such as seals. They are also suitable as protective layers for other packaging materials, such as closures or lids for glass and plastic packaging, pharmaceutical casings, and more.

Commonly used thermoset plastics include melamine-formaldehyde, epoxy resins, and phenol-formaldehyde.

Thermoplastics find applications in a wide range of products and can be manufactured with high precision in large quantities, making them suitable for producing plastic containers.

Well-known thermoplastics are PVC (polyvinyl chloride), polypropylene, polyethylene terephthalate, and polyolefin.

Another trend evident in Chicago is the significant proliferation of PET stretch-blow machines and vendors. The latest reheat models offer broader wide-mouth capabilities, faster production rates, and shorter changeover times. Some models feature innovations like preferential heating or heat-setting capability. Additionally, new integrated or single-stage PET machines can now make bottles from 100% regrind material or switch quickly between round and flat bottle styles.

In extrusion blow molding, new rotary continuous machinery entries are making waves, including the first such unit from a PET machine manufacturer. Two brand-new dual-station machines with updated features are also being showcased.

Other introductions include advancements in 3D blow molding technologies, PET barrier coating technology, PET preform tooling, and new devices like self-teaching leak testers, bottle profile gauges, and bottle packaging systems.

The Fischer-W. Muller division of Krupp Plastics & Rubber Machinery (USA) Inc. has expanded its all-electric offerings to include the long-stroke FMB line, featuring a new FMB4-100 model with a four-parison extrusion head and a 100-mm center distance. Electric servomotors and ball screws govern mold movements, while separate servomotors handle clamping. New controllers offer neck-calibration and blow-pin technology developed by Tahara Machinery Ltd. in Japan.

Other firms like JSW Plastics Machinery and Magic North America are also providing materials on all-electric extrusion blow machines. Uniloy Milacron and American Plastics Technologies will display new all-electric models.

Uniloy Milacron is unveiling its first two-stage PET machine, the all-electric VersaPet. This reheat machine boasts a 75-ton clamp and separate servomotor drives for the stretch-blow pin and clamp. A four-cavity model will produce half-gallon bottles at high speeds.
