4 essential blow Molding Process form heated plastic into hole objects like bottles or boxes. These techniques use air strain to force the melted plastic into molds, offering the bottle its shape. At EX MOULD Co., we employ all 4 methods to supply excellent bottles: Extrusion Blow Molding (EBM), Compression Blow Molding (CBM), Injection Blow Molding (IBM), and Injection Stretch Blow Molding (ISBM).
Choosing the right gadget depends on elements like the size and shape of the bottle and the type of plastic resin used. With over nine years of experience, we know how to select the splendid blow molding system for any product. Our goal is to supply the right bottle every time.
Understanding the variations among those processes will help you make better choices for your plastic packaging. Let’s examine each technique and its specific characteristics.
Extrusion Blow Molding (EBM)
The EBM process starts by melting the plastic resin and forming it into a tube-like shape called a parison. The parison hangs vertically, and air is blown through its center. Then, an element mold clamps across the parison.
A blow pin blows compressed air into the parison, causing the plastic to extend and form mold. This consists of first-rate facts similar to the threads at the neck of the bottle. After cooling, the mold opens, and the bottle is eliminated. The excellent plastic at the top and backside is trimmed, leaving the final product.
This manner is proper for massive bottles or packing containers. It works appropriately with bottles manufactured from High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Polypropylene (PP). EBM is likewise best for merchandise with huge neck openings. It allows the burden of the bottle to be adjusted by controlling the amount of plastic in the parison. This makes it a top-notch choice, while bottles require thicker walls or a couple of plastic layers.
Compression Blow Molding (CBM)
CBM is a specialized version of extrusion molding. Here, the blow pin does greater than, in reality, blow air. It applies physical stress to push the plastic into the neck vicinity of the mold. This outcome resulted in better thread definition and unique neck dimensions.
This device is ideal for bottles with medium to large blow-up ratios, which have a large body compared to a small neck. CBM works first-rate with HDPE, LDPE, and PP resin. It is also an excellent choice for bottles that require extraordinarily tight neck tolerances.
Like EBM, CBM permits weight adjustments by controlling the plastic inside the parison. This method works well for bottles with a couple of layers or apparent window stripes to screen the product stage internally.
Injection Blow Molding (IBM)
The IBM system injects melted plastic into a mold to create a preform. This preform is a small, stable plastic tube fashioned like a mini model of the bottle. Air is then blown into the preform, causing it to increase into the very last bottle shape.
After cooling, the bottle is ejected and moved onto a conveyor belt. This system is ideal for bottles with small to medium blow-up ratios, which frequently have small bodies and necks. IBM offers exceptional precision and works appropriately for bottles requiring tight neck tolerances. It is typically used for bottles fabricated from LDPE, PP, and HDPE Bottle Manufacturing.
Injection Stretch Blow Molding (ISBM)
The ISBM method started the same way as IBM. The melted resin was correctly injected into a mold to create a preform, which was then conditioned and stretched.
Air pressure is used to blow the preform into the mold. The stretching process improves the bottle’s barrier properties, making it more durable and suitable for sure products. After cooling, the mold opens, and the completed bottle is ejected.
This process is proper for bottles crafted from Polyethylene Terephthalate (PET) and works nicely for bottles with small to medium blow-up ratios. ISBM is generally used for water bottles, juice bottles, and PET packing containers that need incredible strength and clarity. It is the preferred choice when lightweight but strong bottles are required.
Choosing the Right Blow Molding Process
The best blow molding process depends on your product needs. The length and shape of the bottle play vital roles. Large bottles with good-sized necks work extraordinarily well with EBM. Small to medium bottles with specific neck dimensions are highly suitable for IBM or ISBM.
The kind of plastic cloth also subjects. HDPE, LDPE, and PP are well suited to EBM, CBM, and IBM. On the other hand, PET is generally used with ISBM.
Weight and wall thickness are also key worries. EBM and CBM permit weight modifications, making them perfect for injection molding for bottles with thicker walls. For merchandise requiring lightweight but sturdy packaging, ISBM is the best choice.
Finally, consider the product’s purpose. Food and beverage bottles regularly use ISBM for PET’s power and clarity. Chemical or business bottles may additionally use EBM or CBM for higher sturdiness.
