Injection stretch blow molding consists of molding a given plastic into a preform. This is done using the injection molding procedure. At the time these pre-forms are produced, they will include the necks of the threads as well as necks known as the finish. The preforms are cooled and then put through the blow molding process. In the ISMB process, preforms will be heated above their glass transition temperature, and then blow molds are subjected to high pressure, and then it is blown into bottles. Generally, the performance is stretched with the help of a core rod, this is done during the process.
The manufacturers have injection stretch blow molding equipment with an output of over 2000 BPH. They have multiple single-stage blow molding capabilities and it will be providing high-quality bottles that are produced from multi-cavity molds. ISBM Mold Injection Machines Supplier mostly prefers this process to generate effective products and to add quality to their client’s requirements.
The main features of
Injection stretch blow molding are
·
They have
flexibility over a wide range of container shapes and filling volumes. This
means that this process is applied to various products and containers
consisting of different shapes.
·
The process has a
high line of efficiency, production rates, and cost-effectiveness. There will
be zero material waste and thus minimizing a lot of energy consumption.
·
This is a simple
operation involving change over and maintenance.
·
The process has high
transparency.
The typical containers that are popularly manufactured are dairy bottles, underarm deodorant bottles, pharmaceutical bottles, etc. The injection blow molding is a process that is incorporating the three basic stages. The plastic is injected into a mold to create a plastic cylinder, this plastic cylinder is then blown into a mold to form a relatively hollow part, and then the form is ejected. During the process, the air is used to create the hollow plastic shape by forcing the soft plastic into the given mold’s cavity. These are the general method that effectively outline the injection blow molding process. ISBM Mold Injection Machines Supplier favors this process more than any other.
The injection blow
molding enriches manufacturers with a variety of benefits
·
There will be no
unwanted scrap material that is generated during this process. This in turn minimizes
the waste.
·
Better and improved
part tolerance that proves to be secure and safe is eventually created.
·
Meanwhile, this
procedure has the capacity of creating good surface finishes.
·
The injection blow
molding can produce a relatively high product volume.
· There are various other benefits of Blow Molding Machines, such as:
1. During the molding process, there will be no excess
material that needs to be trimmed. This is because the part will be formed in
an enclosed mold. The three phases of the injection blow molding processes also
permit the formation of a much heavier threaded neck, with a thin container
wall. This eventually makes injection molding the best-suited process for
creating a safe and secure container closure. This is an important attribute to
keep the workers unharmed or keep them away from any possible risk. Also,
injection blow molding will be used to mold various container types. This means
that several manufacturing specifications will be met.
This process can be used for making blow molded products that have thicker mid-sections and heavier bottoms. This is of immense value to the manufacturers for a wide number of products and ingredients that they can store in the formed container. This way you can get a good surface finish as well. This is crucial for product branding and its display. It must be kept in mind that different methods of blow molding offer comparatively different advantages over other blow molding methods. There is a process that will assure high manufacturing quality and an excellent return on investment. Blow Molding Machines require precise knowledge of each step, hence a professional can carry on the process.
This consists of two different methods such as the two-stage and single-stage process. The single-stage process is further divided into 3 stations and four station machines. In the two-stage injection stretch blow molding process also known as the ISMB process, the plastic is first molded into a preform, this is done by using the injection molding process. The pre-forms are produced with the necks of the bottles, including threads on one end. They are packaged and fed after cooling into a reheat stretch blow molding machine. In this ISB process, the preforms are then heated, this is done by using infrared heaters. The heating is performed above their glass transition temperature. It is then blown using the high-pressure air into bottles by using metal blow molds. These preforms are always stretched with a core rod as a part of the process.
Advantages
· With this process, very high volume products are produced, with a few restrictions on the bottle design. The preforms can be sold as a complete product for a third party to blow. This process is suitable for oval, cylindrical and rectangular bottles. They are suitable for low volumes and short runs.
· Since the performance is not released during the process, the performance wall thickness will be shaped to allow even wall thickness when blowing non-round and rectangular shapes.
