The pet bottle industry is one of the fastest growing consumer markets in the world today. With consumers everywhere looking for more convenient ways to enjoy their pet beverages, the pet bottle industry is positioned to seize the opportunity with multiple product lines. The pet bottle industry is a high margin market with a high profit margin. The industry enjoys significant cost advantages over other beverage manufacturers due to low production cost and higher marketing and distribution costs. The pet bottle manufacturers are looking forward to capturing this lucrative global markets to increase their sales and profits.
Injection Molding (I&M) is the process of heating a liquid injection system (or a single or two-phase pump) at temperatures in order to induce solid, vapor or gas into a workpiece via pressure. The output from the injection molding machine is usually in the form of a plastic, ceramic or rubber product. There are a number of Pet Bottle manufacturers who manufacture plastic products via injection molding; a number of these companies use the "GP" system, which stands for Glass Reinforced Polyester. Glass Reinforced Polyester is an ultra-tough plastic that is extremely durable and has excellent resistance to wear. This makes it ideal for use in high volume production lines, where high pressure is required.
High volume pet bottle production can be highly demanding; as such, there are a number of benefits for the companies who make use of either the "GP" system or the "extruded blow molding" techniques. The extruded blow molding technique can produce a large variety of products. It is suitable for pet bottle production, because the equipment required is relatively lower and simpler than that required by the GP systems. The prisons between the two techniques are also very distinct. In general, both of them produce identical parities, consistency and dimensions, although there can be slight differences in the level of consistency and uniformity.
Extruded Technique Of Pet Bottles
Both the methods can be used successfully for pet bottles, but the extruded technique is more suited for larger production quantities and for high volume packaging applications. At the low end of the spectrum, injection molding machines are suitable for production of a range of small clear to colored plastic bottles. They are also suitable for the production of many types of pet bottles in the shape of animals, including leashes, collars, toys, bowls and food containers. For this application, both the GP and the stage blow molding machines are appropriate, with the potential for each being slightly different.
For high-volume applications, however, both the techniques are capable of producing high-quality plastic products. For example, the high-pressure booster compressor can be employed to create thousands of bottles in one sitting, whereas the extruded machines can be run for shorter periods and with significantly lower pressures. As the size of a production operation increases so do the number of machines and the duration of each session. The choice of which to employ will depend on the nature of the final product, as well as on budget and other manufacturing considerations. For instance, where visual impact is an important factor, injection molding may well be preferable for large productions since the process involves shaping solid plastic rather than simply spraying a colored thickener. Similarly, for high-volume pet bottle applications where appearance is a secondary concern, Extrusion Blow Molding may well be suitable.
Pet bottle manufacturers have a multitude of options available to meet their needs. They can either mold the bottles from scratch, or purchase a ready-made plastic mold that can be varied for different shapes, sizes, finishes and decorations. Molded beverage containers can also be made from a variety of polymer composites, including polyethylene and polypropylene. These materials offer unique advantages over conventional plastics that are not easily molded. Some brands, such as Tark Products, have developed advanced thermoforming technology that allows for different fill levels in the same bottle. Plastic beverage can liners, polycarbonate bottoms and caps, and thermoplastic olefin are also popular options.
