Blow molding blow moulding , or plastic blow molding, is a fabricating process that manufacturers use to create hollow plastic parts and products. It is named blow molding because it involves blowing compressed air into molten plastic so that it expands like a balloon and takes a particular shape. Request A Quote.

If you need a worry free solution for your project, allow us to serve you as well. Manufacturers use the blow molding process in order to form a smooth, airtight, uniform product that does not need to be assembled.
Also, blow molded products are capable of holding a variety of substances such as herbicides, pesticides, cosmetics, and automotive oil.
Manufacturers use blow molding to make numerous products. Examples include: automotive ducting, water bottles, food storage containers, plastic totes, recycling cans, garbage cans, gallon drums, hoses, planters and watering cans. Also, manufacturers blow mold cases and any other hollow consumer item that has a three-dimensional shape.
After they sold the rights to their invention in to the Hartford Empire Company, a select number of manufacturers across the country began using the blow molding process for their purposes.
One of the first items American manufacturers mass produced was the plastic bottle. While the method had incredible potential, prior to World War II, manufacturers did not have access to many types of plastic. In WWII, the need for synthetic plastics increased, and engineers responded by designing many new varieties. This trend continued after WWII, when manufacturers began producing plastic containers for the home.
One of the first items American manufacturers mass produced was the plastic bottle in By , 60 years later, the US was producing upwards of ten billion plastic soft drink containers. While plastic and plastic injection is as popular and present as ever, there is now a movement to use materials that create less potential waste and litter. One way that plastics manufacturers are seeking to keep up with the green movement is by creating new products from recycled products.
The plastic utilized for these processes are all thermoplastic resins. They include acetal, polysulfone, polyamide, polystyrene, butadiene styrene, polyvinyl chloride PVC , polycarbonate and high-density polyethylene HDPE.
Polysulfone thermoplastics are durable, strong, rigid and thermally stable polymers. These high-performance plastics are highly resistant to a variety of chemicals with pH levels between 2 and 13, including: bleaches, electrolytes, alkalis and mineral acids. They are reasonably resistant to hydrocarbon oils and surfactants. They have above average compaction resistance, so they work well in high pressure applications. Polyamides are characterized by their durability and strength.
They can occur naturally or be made synthetically. Polystyrene is an inexpensive polymer used for a variety of purposes that do not require sealing from water or air. It is available as a solid material or a foamed material think Styrofoam. Manufacturers use it to blow mold plastic containers and bottles of all sorts.
However, polystyrene takes a very long time to biodegrade, and has been found in alarming quantities in the Pacific Ocean and along shorelines. Butadiene styrene, not to be confused with styrene-butadiene rubber SBR , is a thermoplastic elastomer made from styrene and butadiene.
ABS is strong, shiny, heat resistant and impact resistant. It is available as a flexible or rigid material. Some of its many blow molding applications include: bottles, plumbing components and non-food packaging. Polycarbonates are thermoplastic polymers that feature carbonate groups in their makeup. They are strong, durable and impact resistant. However, they have poor scratch resistance and poor chemical resistance.
HDPE is a thermoplastic known for its high tensile strength and high strength-to-weight ratio. It is also water resistant and solvent resistant. There are three methods in which blow molded plastic products can be produced: extrusion blow molding, injection blow molding, and stretch blow molding.
All blow molding processes share the steps of 1 melting and forming the plastic, and 2 introducing air pressure. The first step in the blow molding process involves melting the plastic, and then using injection molding to form it into a preform, or parison. A parison is a piece of plastic shaped like a tube with a hole on one end which allows compressed air to pass through. The preform, which is soft and moldable, is pushed by a metal ram and expanded to the designated height of the product.
The parison or preform is then clamped into a mold cavity. The ultimate shape of the blow molded plastic depends on the shape of the mold cavity. Air pressure is introduced to the inside of the parison via a blow pin. The air pressure causes the parison to expand like a balloon and fully take the shape of the mold cavity. The final product can be cooled either by running cold water through the mold, by conduction, or by evaporating inconsistent fluids within the container.
The blow molding process takes a few seconds; blow molding machines are capable of producing up to 20, containers in an hour. Once the plastic part has been cooled and hardened, the mold opens up and allows the part to be ejected. When preparing a custom blow molding procedure, manufacturers must decide on a few different things, mainly: the material they will use, the blow molding process they will use and the shape of the mold cavity.
The decisions they make depend entirely on the client application specifications and requirements. For example, if the product requires strong compaction resistance, they will likely consider a material like polysulfone.
While blow molded products come in an assortment of standard shapes and sizes, there are some products that are used for special applications and must be made via custom blow molding. To make sure you are on the same page, they will first create a prototype to share with you. However, if you are short on time or your budget is small, your manufacturer can also blow mold your products with a standard mold. They typically have a wide variety of standard molds with which they make commonly shaped and sized containers, jars and the like.
Extrusion blow molding is the simplest of the three blow molding methods. Extrusion blow molding involves melting plastic extruding it into a parison, then expanding the parison with compressed air. Extrusion blow molding allows for a wide range of sizes, shapes, handle ware, and openings for containers. Notably, extrusion blow molding only makes hollow products.
When creating the containers, the extrusion blow molding process utilizes two mirror molds, which result in a seam running down the middle of the product. Injection blow molding hybridizes the processes of blow molding and injection molding.
During the injection molding process, the plastic preform is injection molded before being blown into a mold inside the injection blow molding machine. The injection blow molding process is not suitable for manufacturing any kind of handle ware but is permissible for small containers.
These processes are often used to manufacture bottles for beverages such as water and juice. ISBM injection stretch blow molding involves injection molding a preform, and then moving it to the next station to be blow-molded. ISBM is a costly process, and is used to manufacture liquor bottles, water bottles, and peanut butter jars. RHB reheat and blow molding involves purchasing a preform from another vendor who has already injection-molded the material.
The preform is reheated to prepare it for the blow-molding process. First, blow molding is cheaper than injection molding. In part, this is because it requires so few tools. Second, unlike many others, blow molding is suitable for fabricating plastic parts that are hollow.
Third, blow molding has a faster cycle time than other processes, such as rotational molding. Another benefit of blow molding is its ability to perform high volume production runs. On top of this, it can be used to mold complex parts. First, blow molding can struggle to yield even wall thickness. Also, from time to time during this process, the plastic can spring leaks or develop holes. If you have decided that blow molding is the right process for you, your next logical step is locating the right manufacturer.
Who is the right manufacturer? The right manufacturer is the one who will not only manufacture blow-molded plastic parts to your satisfaction within your timeline and budget, but who will consult with you and provide high quality customer service from beginning to end. To find a blow molder like that, check out those we have listed on this page. To choose from them, start by putting together a list of your specifications.
