The Basics of Blow Moulding: What You Need to Know
Blow moulding is a versatile manufacturing process used to create a wide range of plastic products, from bottles to containers. This blog post will provide you with an overview of the blow moulding process and its key components.
Blow moulding process begins with the combination of HDPE resin and color master batches, which are loaded into a hopper. From there, the resin is heated, transforming it into molten plastic within a screw barrel. This molten plastic is then extruded and shaped into a parison before molds close around it. A metal knife trims any excess material, and dry air is blown into the parison to create the final container shape. After cooling, the container takes on its permanent form.
The Advantages of Blow Moulding Technology
Blow moulding offers numerous advantages over other manufacturing processes. First and foremost, it allows for cost-effective production of complex shapes, making it ideal for items like bottles and containers. Additionally, blow moulding results in lightweight yet durable products, reducing transportation costs and environmental impact.
