Blow molding is one of the applications of filler masterbatch. In this article, we will find out information about the filler masterbatch for blow molding to answer the question: Why filler masterbatch is the material for making blow molding products? Where you can buy filler masterbatch for blow molding?
1. Overview of filler masterbatch for blow molding
Before discovering the information of filler masterbatch for blow molding, let’s see what blow molding is.
Blow molding is a specific manufacturing process by which hollow plastic parts are formed and can be joined together. The majority of bottles, barrels, and containers are manufactured by blow molding. The most common plastic parts made with the blow molding process are bottles. Some parts can be converted from rotational molding to blow molding.
By blowing up a heated plastic tube until it fills a shape and forms the form you want, blow molding is an assembly technique used to create hollow plastic objects.
What are the applications of using filler masterbatch for blow molding? Plastic, empty, thin-walled parts—such as jugs and holders—that come in a variety of sizes and shapes are made via blow forming. Smaller items can include jugs for gasoline, drain, water, fluid cleanser, and cleaner; larger holdings can include plastic drums, tubs, and storage tanks. Various thermoplastic materials can be used to frame blow-shaped items, such as the following:
Low-Density Polyethylene (LDPE)
High-Density Polyethylene (HDPE)
Polyethylene Terephthalate (PET)
Polypropylene (PP)
Polyvinyl Chloride (PVC)
There are specific techniques used in blow forming:
Extrusion blow molding: The liquid plastic is forced through a bite of the dust head by an extruder using a twisting screw to shape the parison around a blow stick. To allow for the two form pieces to close on the parison blow stick, the parison is ejected vertically between them. The parison swells as a result of pressured airflow passing through the blow stick. This type of blow shaping is the most well-known and is used to create a large number of relatively simple pieces. Filler masterbatch is usually used in extrusion blow molding.
Injection blow molding: To frame the empty parison, the liquid plastic is infusion-shaped around a center inside the parison shape. Both the parison and the center are switched to the blow form and securely braced at the moment when the parison shape opens. At that moment, the center opens, allowing pressured air to cause the parison to inflate. Because of the reduced generation rate, this is the least frequently used approach, although it may shape more jumbled components more precisely. Often, injection blow shaping is preferred for small, intricate jars, such as those used in pharmaceutical applications. Filler masterbatch is usually used in injection blow molding.
Stretch blow molding: The parison is framed in an approach similar to blow molding injection. However, after being switched to the shape below, it is heated and stretched downward by the center before being expanded. The plastic gains a stronger quality from this extension. Extend blow molding is typically used to create pieces, such as pop jugs, that need to be extremely durable or able to support some internal weight.
2. Advantages of using filler masterbatch for blow molding
Filler masterbatch is used in blow molding for certain reasons.
First, using filler masterbatch for blow molding is cost-saving. CaCO3 filler masterbatch reduces the cost of producing plastic by replacing a significant amount of virgin polymer in extrusion, injection, and blow molding procedures.
Second, filler masterbatch for blow molding improves processing, and output, whiteness, and gloss, stiffness to the end product, reduced energy for machine usage, improved dimensional stability, shaping, and better printability.
Lastly, with the filler masterbatch customized to the client’s requirements, the properties, characteristics, compatibility, percentage of filled mineral, and particle size depend upon the requirements of the clients.
