Common plastic materials used in blow moulding machines include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. These materials have their own characteristics and are suitable for different application scenarios. For example, polyethylene has excellent impact resistance and low temperature performance, and is widely used in the production of water storage tanks and fuel containers; polypropylene is widely used in food packaging and pharmaceutical containers due to its light weight, high strength and chemical corrosion resistance; polyethylene terephthalate is the preferred material for beverage bottles and cosmetic containers due to its high transparency and good air tightness.
In the process of blow moulding machine material selection, it is necessary not only to pay attention to the mechanical properties of the material, but also to consider its processing performance and environmental impact. Materials with good processing performance can maintain stable fluidity and formability during blow moulding machine blow molding, reduce scrap rate and improve production efficiency. At the same time, environmental protection requirements have promoted the application of renewable materials and degradable plastics. For example, bio-based plastics are becoming a trend to replace traditional petrochemical plastics, which not only conforms to the concept of sustainable development, but also meets consumers' demand for green and environmentally friendly products.
The choice of materials also places requirements on the design and function of the blow moulding machines themselves. For example, when processing high-viscosity or heat-sensitive materials, blow moulding machines need to have higher precision and temperature control capabilities to ensure molding quality. In addition, the wear resistance and corrosion resistance of the material also have a direct impact on the service life of the machine, which requires blow moulding machine manufacturers to take into account the characteristics of the material and the performance requirements of the equipment when designing.
