The Process of Extrusion Plastic Blow Molding

Blow molding production companies may implement extrusion blow molding services, the manufacturing process that they use renders hollow plastic forms that have thin walls that can be used to contain other materials. This hollow formed plastic product is called blow molded plastics.

Typical Products Formed from Extrusion Blow Molding

Typical types of products that are formed using this method are items such as milk jugs, water bottles, cosmetics bottles, and many other plastic containers. Large plastic storage boxes and large plastic storage tanks can be fabricated using the extrusion blowing method.

What are the steps to create an Extruded Blow Molded product?

After a mold negative is designed and created with the exact specs of the final molded product is made, a small tube injector called a parison is made and sealed on one tip. The parison is placed on the top edge of the closed mold, and compressed air is then blown into the open tip of the parison and the air pressure forces the tube to expand and conform to the shape of the surrounding mold. After the plastic cools and sets, the mold may be opened and the finished product may be removed form the mold.

Advantages of Extrusion Blow Molding

The advantages of extrusion plastic blow molding are numerous. Not only is the process flash free, but also blow molded products can be form or very large or small sizes. As well, the blow molding process is inexpensive, precise, and can help to lower product assembly costs.

How to Have an Effective Blow Molding Product

You should try to employ the best engineers since the planning and design process can be an elaborate multi-step process in order to meet the product requirements.

When the mold design is fully set, then the engineers will collaborate with the finishing team to test for quality assurance. The quality testing process is essential to ensure that the finished product functions as desired and as designed and corresponds well with the design specifications before mass production is started.

Upon certification by the production team and engineers as well as client approval, the order is run on the production line.

The critical element to effective extrusion blow molding is collaboration and a team effort. When all team members bring their best to the design and development table, the end product will fulfill the client and end-user requirements. Teamwork fosters the highest level of quality and quality material produce a final product that you can be proud of.

Extrusion Blow Molding Design & Manufacturing Advantages

In the world of in-house design and engineering, Western Case is able to provide its customers with comprehensive product design. From start to finish, customers can benefit from Western Case’s past experience in both design and engineering. When it comes to blow molded product design, the team at Western Case knows exactly what to do in every step of the product design process.

Blow Molding Design & Manufacturing Considerations

Blow molding, or extrusion blow molding, according to Engineer’s Edge, is the manufacturing process that creates hollow thermoplastics. When done in a split mold cavity, air pressure is applied to a heated plastic material, generally called parisons.

That process causes the material to expand, similar to a balloon. As the material expands, it presses against the walls of the mold cavity, causing the material to take shape. There are many blow molding manufacturers and blow molding plastic companies; it is important to select a company carefully.

Extrusion Blow Molding Advantages:

  • Flash free
  • Sizes ranging from very small to very large
  • Less expensive molds
  • Good dimensional precision
  • Reduced assembly costs

Design Considerations Condensed:

When completing a blow molding project, the wall thickness should always be uniform in order to facilitate the rapid molding cycle time. During these projects, sharp corners should be avoided wherever possible, and the draft angle should always be perpendicular when the mold tool is open in the correct direction. Finally, the thickness of the body wall should never exceed a 2:1 ratio.

Advantages & Disadvantages to Extrusion Blow Molding Plastic

Blow molding plastic is a procedure where hollow 3D articles are produced using various kinds of thermoplastic materials. These materials are usually available in powder or granular form. The simplest blow molded tool has two parts, which are closed and consist of a cavity inside.

Hold Molds Work in Extrusion Blow Molding Technology

A plasticizing cylinder is used by blow molding manufacturers for softening the granular or powder materials, which are then thrust into a parison (vertical tube). An open mold surrounds this parison that is later closed. Thus, the bottom end is sealed effectively and then, the other end is used for sealing it in a pneumatic manner.

The mold’s geometry and the parison’s size determine what the distribution, wall thickness and other dimensions of the manufactured article would be. This makes them important factors, along with the die design, which is affected, by backpressure, land length, melt compression and melt flow pattern. For producing bottles that have uniformity in wall thickness, the wall thickness of the parison is controlled using various pre-stated steps by manufacturers.

Advantages of Extrusion Blow Molding Plastics

Advantages: Because of lower pressure, the mold costs in extrusion blow molding are lower as compared to injection molding and the machinery costs are low as well. Also, it’s easy to mold external threads. Making open-ended parts that are large can be done by splitting open a closed molding.

Disadvantages of Using Extrusion Blow Molding

Disadvantages: As the diameter of the mold increases, the corners and areas with the thinnest walls have close tolerance. Plus, extrusion molding has longer cooling times than injection molding. Also, it is not possible to mold in holes except after the molding.

Discover the Benefits of Blow Molded Products Using the Extrusion Process

The extrusion blow molding process is used to produce a wide variety of containers and household products that we use every day. A very high output production operation, blow molding manufacturers usually apply it in the manufacturing of plastic containers and bottles. As an automated sequence, it is generally operates in conjunction with downstream procedures such as the labeling and filling of the containers. One of the requirements for blown containers is that they be rigid, which is reliant on several factors, wall thickness being chief among them.

Production of blow molded products is very cost efficient for a variety of reasons:

  • Low tooling costs
  • Versatility in tooling. Molds can be made to accommodate more than one type neck finish or body section.
  • Adaptable Production. Both bottle weight and neck I.D. are easily adjustable to a variety of specifications.
  • Vast range of container sizes. Containers of 1 liter or less are produced most efficiently, but production of containers form 1 oz. to over 55 gallons can be accomplished.
  • Shape isn’t constrained by the blow up ratio. Blow molded products may be manufactured with or without handles.
  • Machines of varying sizes. Molds can be specifically geared toward volume requirements.

The Advantages of Blow Molding Versus Injection Molding for Hard Tool Cases

Most product manufacturers have a choice to make when they need custom cases. There are many advantages to using blow molding as compared to injection molding cases.

If you are considering injection-molded cases over blow-molded cases, then there are a few advantages and disadvantages to using either process.

Advantages of Blow Molding Cases

The process that blow mold manufacturers use is not time-consuming or lengthy. The process is affordable and produces long-lasting cases that are lightweight and available to use in many different situations.

We can blow mold products in a variety of volumes, including low and high. The blow molded process gives product designers a good amount of flexibility over the manufacturing of the products.

Blow molded products can produce a high volume of products in a quick turnaround time. Having the ability to produce a high volume gives product producers the ability to create a lot of cases in a short amount of time, when needed. In the economy now, manufacturers can match the demand for products as they happen

Advantages of Injection Molded Cases

Injection molding involves more effort on creating the mold. The molds are specially designed. For this reason, the mold specifically addresses the specifications for the product. Manufacturers often run injection-molded products in high volumes. The product producer will likely have many cases to put in stock as a result of the need for high volume. The injection molding process is more ideal for a high volume of cases needed.

Types of Products Blow Molding Produces

Blow molded products are not only for cases, but for a variety of products.
