Advantages to Blow Molded Cases and Products

Advantages of Custom Blow Molding Cases & Products
Blow molding is a type of manufacturing method which uses a custom mold to form hollow plastic pieces. The molded plastic forms a vessel which can protect goods while in transit, because it has been shaped to the exact size and shape that the goods will need while in route. There are several advantages to using blow molding, although there are some disadvantages as well.

For Cases


  • Reduces Costs
  • Manufacturers can create more varied and intricate designs


  • Difficult to mold in-holes
  • Cost rises as size increases

For Products


  • Lets companies meet consumer design for variations in plasticware
  • Quick manufacturing time with high volume outputs
  • Permits new designs for everything from fuel tanks to toy wheels
  • Lower pressure during production reduces manufacturing costs
  • Has several methods of production including extrusion and injection. Injection and Injection stretch methods use a preform whereas extrusion melts the plastic into a rounded parison, which is then removed from the furnace, attached to a mold, and compression air is blown to form an exact match.
  • Can be automated
  • Lower machinery and tool costs
  • No wasted material, all leftovers can be reused or recycled

If you have more questions on blow molding advantages, you can give Western Case a call for a consultation, where they will be able to go over everything with you and give more detail on how blow molding can be a great solution for your needs.

Manufacturing Blow Molded Products Using Extrusion

Blow Molded Traffic Products Using Extrusion ManufacturingBlow molding is used in the manufacturing process to create products that are used to produce hollow parts that we see everywhere, including septic tanks and eye dropper tools. It is derived from the glass blowing industry. The impressive technique is used in other aspects of blow molding, along with all bottle (i.e. detergent, bleach) and food product containers.

Blow Molding Plastic Products

Most containers contain parts that include polypropylene, LDPE, and LLDPE. This is a high-density thermoplastic that is highly preferred with blow molding. The orange construction cones that we see on the highway were created from our extrusion blow molding technique.

How Does Blow Molding Work

A molded tube of resin is extruded with an annular dye and captured between two molded halves that shape out your desired pattern. The mating surfaces on the mold pinch together creating high pressure air in a captured tube that assists in the shaping process.

An inflating process takes place to conform the inside shape of the mold. Most barricades were once constructed of wood and are now, constructed with very durable plastic that is commonly shaped by the blow molding process. More importantly, plastic barriers are becoming increasingly popular on construction projects around the country.

What Products Are Created Using Blow Molding?

Plastic safety products used by blow molding are used to keep pedestrians safe and control traffic. Thousands of containers each year are produced by blow molding techniques. Conveniently, let traffic know what areas are off limits or prevent your employees from entering a dangerous work zone.

Eco-friendly products have recycled materials that calls for less virgin materials. You can get custom products made on a short or long run basis. Semi-custom blow molded products are also very popular. They provide lightweight, easy to assemble products, and easy to breakdown plastic barriers.

Forming High-Quality Plastic Products Using Blow Molding


Traffic Safety Plastic Blow Molded Products

Plastics are non-metallic compounds, which are produced synthetically. When soft, plastic can be shaped into numerous forms. These shapes can be hardened for commercial purpose. Products for molding plastics are readily available. They include jars, plastic tubes, bottles, kitchen utensils, grips, accessories, cases, and protective caps.

Stages of the polymer-making process

• Polymer production: This phase involves creating polymer in a granule, powder, or sheet form. It may entail mixing of the polymer of the best addictive with other polymers to attain a finished product that has the desired properties.

• Production of thermoplastics: At this stage, the powder, sheet, or granule material obtained from step one is heated until it softens, molding the softened material to the desired shape and eventually cooling it. In other words, this stage involves molding the thermosetting materials to the appropriate form and then heating them to trigger a chemical reaction that speeds up the formation of highly linked polymer from cross-link polymer chains.

The plastic molding process

1. Blow molding

Blow molding helps in creating hollow plastic items. Leveraging compressed air that blows up the tube, forcing it to adapt to the cool mold, forms a molten tube. Blow molded products include tubes, bottles, and containers.

2. Extrusion forming

A broad range of plastic products, ranging from curtain rails, window frames, film, household guttering, to film, can be formed from extruded sections. Extrusion entails the pushing of the liquefied thermoplastic hyper-linked polymer through a die. When forming curtail rail, the extruded material must be cold.

A die offers a cylinder-shaped extruded material and, thus, can aid in the formation of a thin sheet or film. Compressed air is utilized to inflate the hot cylindrical material to attain a tube-shaped sleeve of the thin film. When the material expands, the thickness reduces. It is easier to convert film formed through the extrusion process into bags.

Since plastic molding is an extremely technical process, you will need professional assistance for this kind of manufacturing business to be competitive and profitable. Direct all your questions concerning the plastic-making process to our team and we’re glad to help with your project.

Blow molding has a lot of similarities to injection molding except there is a molten tube the plastic comes out of in a liquid form. The mold is designed to close and push the liquid out and conform it into whatever shape is required. Once the liquid has cooled, the forming of the hollow area is accomplished. This is how tubes, numerous types of bottles and a variety of containers are made. If you have a project you want quoted, contact us.

Finding The Right Blow Molding Manufacturer For Your Business

Are you looking for a plastic mold manufacturer to create parts or products for your project? Below are some of the key things you should keep in mind when selecting a plastic manufacturer to create items for your company.

Questions to Ask the Blow Molding Company

The most important thing to consider is whether the manufacturer can meet the needs of your company.

Do they have the resources and manpower to fulfill orders and deliveries on time? Are they a reputable company?

It is very important to select a trustworthy manufacturer who has a proven track record or creating quality products. The last thing you need on your hands is for customers to complain your products were made from poorly constructed materials. Save your self the hassle and choose a reputable company.

Important Considerations – Location and Cost

Another important thing to consider is the location and cost. One company may offer a slightly better product but is much farther away than a local firm. The farther the manufacturer is the more money it will cost to transport the goods to your warehouse or facility.

You should also consider the cost of the product. Sometimes it is best to hire a local firm because you can get the products quickly and affordably than from a more distant firm.

The Extrusion Blow Molding Process in Plastic Bottle Production

Blow molded products are all around us. From water bottles to carrying cases for power tools, blow molding is a fast, efficient, and inexpensive way to manufacture many of the things we use every day.

Processes to Plastic Bottle Blow Molding

There are four different blow molding processes used to produce plastic containers and bottles: injection blow molding, stretch blow molding, reheat and blow molding, and extrusion blow molding. Of all the processes, the least complicated is perhaps extrusion blow molding. It is also among the most versatile and cost effective ways to produce a vast array of different products.

Extrusion Blow Molding Production

In extrusion blow molding production, a tube of hot plastic called a parison is extruded into a mold that has been water cooled. The mold is then closed and air is blown into the tube to inflate it to the dimensions of the mold. Once the hot plastic hits the cooled mold, it “freezes” and maintains the shape of the mold.

Extrusion blow molding is generally considered to be the most versatile of all the blow molding processes because it allows for a much wider variety of sizes, shapes, handles, and neck openings. Injection blow molding on the other hand, is suitable only for smaller containers with no handle ware involved. Extrusion blow molding products can be produced at a lesser cost in part because the molds are much less expensive to produce and can be made in a much shorter time span.
