New Innovations Regarding Injection Blow Molding

Injection blow molding, as its name would suggest, is a combination of plastic injection molding and blow molding that creates hollow, thin-walled plastic containers that are smaller and does not have handleware. It is faster than extrusion blow molding, and offers higher precision. Parts may have a threaded neck for screw-on lids, very thin yet strong walls and safety enclosures like those on pill bottles.

Injection blow molding companies have been reaching out to discover ways to make their facilities more “green” and the innovations that are now being utilized have been very impressive. Businesses do more then just simple recycling programs. These companies have added water chillers in the injection process that causes drastic savings in the energy costs of the manufacturing procedures. Also many companies acknowledge that plastic products are a big contributor to the overall pollution in this world and these manufacturers are designing new models that use less plastic. For example, in the water bottle industry there are innovations in the water bottle design that utilizes a thinner wall layer. Water bottle manufacturers also engineer new bottles that will bio-degrade at a much faster rate than bottles which were made five years ago.

Innovations like this are a catalyst for not only a greener world but also profits for companies. Some consumers gravitate toward corporations who are environmentally conscious. These companies are not compromising the integrity of their products but merely updating the methods in which they produce plastic items. Many companies are even expanding their facilities due to the increased demand on the industry for more injection blown products. These expansions provide more jobs for constructing and maintaining the facility. This increase also allows for more opportunities for innovation and manufacturing growth. There is something to be said for those companies that make investments into renewable energy solutions and building upgrades. Solar panels and wind turbines cannot power an entire manufacturing facility but long term energy savings will result in savings for the company and for the customers.

Injection Blow Molding

Injection blow molding is a two step process that uses a mandrel to form the preform, and a blow molding machine to form it into a plastic container. Thermoplastics like high density and low density polyethylene, polycarbonate, polypropylene, polyvinyl chloride, Barex and polyethylene terephthalate are all used in injection blow molding to produce containers like tanks, jars and bottles. Pop bottles are most often made by this process because the design is not limited to uniform thickness—thicker bottoms and middles are possible by increasing the cavity around the mandrel in the second step of the injection blow molding process. They are also able to handle the pressure generated from holding carbonated beverages. Injection blow molded products are usually made in very high volumes, in order to offset the higher cost of setting up 2 different molds for one process.

Since it is essentially 2 forming processes combined into 1, injection blow molding involves more steps than other forms of blow molding. First, a parisan made of plastic is formed when a thermoplastic preform is heated to molten form and injected around a hollow mandrel called a blow stem. Once semi-cured but still soft and formable, the newly formed parisan, which is still around the stem, is placed into the blow molding chamber. The steel blow stem then extends, forcing the plastic to elongate to the desired size of the product, which will also increase its overall strength. Then, compressed air is injected through the hollow blow stem and into the parisan. The almost-molten plastic inflates like a balloon and is blow against the walls of the mold cavity, taking its shape. After it cools and hardens, the newly formed plastic container is ejected from the mold. It exhibits a seamless design and does not need to be trimmed. Injection blow molding machines use multiple mandrels, and may form up to 12 containers at one time.
