Improve Production with Compression Blow Forming

Injection blow moulding is a process that has been around for over 100 years. Blow moulding is currently used to manufacture a variety of plastic products, including bottles and other plastic containers. Blow moulding companies have used the same manufacturing techniques for several decades, but now there is a new option that will increase output, improve plastic quality, and increase the sustainability of each plastic product produced by the machine. This variation on classic blow moulding, known as compression blow forming (CBF), is the new answer to old-fashioned blow forming... Read More

The Versatility of Blow Molded Cases

Made from the process of blow molding, blow molded cases are durable, lightweight, cost-efficient and recyclable. You would have to try in order to break most of these cases. The hollow, thin-walled cases and containers are formed by using compressed air and melted plastics. The process begins with the extrusion of a parison or tube. This parision is placed inside an open mold as air flows inside of the parision, expanding the molten plastic. The new protect settles into the desired shape as it cools. After cooling, the new product... Read More

Plastic Blow Moulding Containers

Many of us don't go a day without using something that has been made by the process of plastic blow moulding. Whether it be a pop bottle, gallon of milk, a spray bottle, many cosmetic products or any other type of plastic container, they are all around us and commonly used as the packaging for many products. These items are usually all disposable and when the contents inside are finished being used they can simply be tossed out or recycled which makes them very convenient for consumer use.

Blow Moulding

Blow moulding, more commonly known in the US as blow molding, is the process of using compressed air and molten plastic to create hollow, thin-walled containers. Blow molded products take their shape according to the form of the mold cavity that the molten plastic is forced into.

Blow molders manufacture many different products, including toys, blow molded cases for transport and storage, sports equipment, garbage cans, planters, and most commonly, blow molded containers like plastic bottles for industries such as beverage, petrochemical and automotive. Blow molded plastics are all thermoplastic resins, and include high and low density polycarbonate, polypropylene, polyvinyl chloride, polystyrene, polyamide and acetal. The purpose of blow molding is to form a uniform finished plastic product that is smooth, airtight and does not need to be joined together in any way. While injection molding and rotational molding are more precise methods of plastic molding, blow molding offers the advantage of high-volume capacity, efficiency and relatively low costs. Blow molded products can be formed from standard and common die-cast cavities, but custom blow molding can be used to create specific products for unusual and unique purposes. It is the most well-suited method for forming hollow plastic parts and thousands of applications benefit from the versatility of the process combined with the strength and durability of the products.

Injection blow molding, extrusion blow molding, and stretch blow molding are the three most common types of blow molding which differ during the pre-form stages. Each variation has specific advantages and application uses, yet the basic process of blowmolding is straightforward. The plastic is melted down and formed into a parison which is clamped into a mold, a blow pin is then used to force compressed air into the parison and the molten plastic expands to fit the shape of the cavity. Controlled and constant air flow is essential to the quality of the final outcome as varying wall thicknesses compromise the strength and durability of the product. Blow molders have to ensure the constant expansion of the plastic in the mold to achieve uniform wall thickness in the product. The cavity is cooled, usually by conduction, and the hardened plastic product is removed from the mold, sometimes with the assistance of ejector pins. The process usually takes a matter of seconds and therefore blow molding machines can produce high-volumes of durable plastic products in short periods of time with minimal finishing requirements.
