Blow Molded Versus Injection Molded Carrying Cases
Carrying cases made through blow molding are considered superior to those made through the process of injection molding. The blow molding process creates cases that are both lightweight and durable, and which can be used in a variety of ways. Blow molded plastic equipment carrying cases are thus ideal in situations that require a prototype or a demo kit.
Blow molding is a process in which plastic is blown into a metal mold to form the case. The durability of the case comes from its seamless design and through the use of thermoplastics, which are state-of-the-art polymers known for their durability. Western Case has perfected their products through the use of thermoplastics.
Western Case will give their users peace of mind when storing, carrying and traveling, and also offer these features:
• Resistance against impact
• Insulation from low temperatures
• Protection from chemicals and other threats

Blow molded cases produced by Western Case are perfect in situations requiring a custom design. This is because the design process is neither time-consuming nor exceptionally costly. However, the method still allows for the production in large or small quantities of cases that come in a variety of designs.
Extrusion Molding, Its Advantages and Disadvantages
Extrusion molded cases also use thermoplastics, but are made differently. Extrusion molding is a practical way of producing any numbers of custom cases. Extrusion molded cases can be produced in large quantities and offer complex designs and intricate features. Extrusion molding is ideal for creating standard-sized cases that are resilient and versatile.
Blow molded products have revolutionized the product industry and are needed in the amount of plastic ware currently required. This method enables fast production so companies are able to manufacture many plastic containers. Machinery for the production of plastics has been specifically developed to enable blow moldings with three dimensions. Production is supported through automation and the improvements made in machinery raise production speed even higher.
Blow molding allows everything to be done in one place whether it is a customized product or has single or double walls. The products are flexible and customization is easy. All capabilities are enhanced and it is very useful in the production and design required by services in the engineering field. Both the manufactures and the engineering staffs are able to use teamwork to exceed the needs of their customers. A level of quality is expected and achieved with this process.
Blow molding is used in the manufacturing of many kinds of products, including ducts for the automotive industry, items needed to ensure traffic safety, wheels, many products for the home, the seats for stadiums, toys, coolers, floats, doors and containers.
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.
Today’s manufacturing environment is calling for plastic parts that can be used to make a variety of things that include auto body parts. Plastic has become a very popular manufacturing material for many corporations and businesses. Plastic requires a unique process to bend it into shape for the use of its desired specifications. This brief article will give you details on the different types of molding, advantages and applications.
Blow Molding For Hollow Objects
Blow molding works extremely well on hollow items like bottles, safety cones, stadium seating, and more. It consists of high-end blow molded plastic parts and the process of extrusion blow molding. The process begins with a parison that is inflated by air. The air pushes the plastic against the mold to form a shape.
Once a cooling process takes place, the bottle is ejected. The blow molding process continues until the designed-to-manufacturer high-end, one-piece hollow objects are created. This is an effective process for making a large quantity of items on a production line.
Blow molding is an economically advantageous process that creates quality uniform, thin-walled products. Blow molding is widely used in the transport industry. As the transport industry continues to develop rapidly, blow molding meets the demands of a growing industry.
The Benefits Of Blow Molding
– Structural/impact-resistance levels
– Great for pipes used for circulation of fluids
– Impressive geometric configurations
– Over-molding techniques
– Insert molding
Thousands of transport industries make products using blow molding, including spoilers, ventilation hoses, four-by-four vehicle step plates, fuel tanks, wakeboard ballasts and much more.
Blow Molding creates a finished plastic molded product from melted plastic. A designer for either product production generally will only work on designs using one of those methods in manufacturing. A thorough understanding of the product is needed.
How a Blow Molded Product is Created
A blow molded product is created when hot molten plastic is pushed through a die. This hot plastic is actually stretched and cooled while it is still in the air. It can be tricky to maintain stability at all times.
Blow molding can offer value in that you can create many different shapes. For instance, in the production of shampoo bottles, there is an air pocket created inside the bottle. Blow molding uses a process that cuts down on wasted plastic because of the mold.
Markets That Use Blow Molding
Industries that use blow molding create products and parts that include the automotive, traffic, sports, hospitality, toy, and food equipment industries.

4. Protection from theft and other unknown elements. Using a good, solid and durable carrying case can ensure protection from all types of things that are likely to occur, including theft. Protect your devices during shipping and carrying with durable cases to make sure that they good to where they are going in good condition.
The blow molding industrial vertical has evolved so that it is almost universally used with plastic. Plastic blow molding is advantageous due to the significant increase in production capabilities.
This allows companies to produce far greater quantities in a shorter period of time. Molding machines allow for three-dimensional moldings, significantly reduced flash, and a much faster production cycle.
The Disadvantages of Blow Molding
Blow molding does have its disadvantages as well. Polymer is a necessary material, which can have adverse affects on the environment. We have all seen the commercials describing the number of plastic water bottles that are used everyday around the world.
The biggest disadvantage may be the negative environmental effect associated with plastic use. Plastic isn’t biodegradable and it typically makes its way in massive quantities into landfills. There is also the concern caused by such a wide use of petroleum. This is a valuable resource that is being reduced by its use in plastic production. However, recycling is available to allow for plastic to be reused.
Techniques Used in Plastic Product Production
There are multiple techniques for plastic production. Perhaps one of the most common is extrusion. The extrusion form is that method mostly associated with glass blowers. Air is used to create the open inside part of the product.
Looking to start a blow molding project? Western Case helps using an extrusion blow molding process to manufacture products in a variety of industries. We recently came across a study that explains an overview on the market for using blow molding.

Extrusion Blow Molding
There are many benefits to using extrusion blow molding as manufacturing for your project. The process is used to create containers, bottles, cases, toys, car parts, and many more items.
During the process, the plastic is melted. Once it is melted, it is shaped into a hollow tube, also known as a parison. This is accomplished by forcing the plastic through a die. The product is blow molded by blowing air into it to inflate the product. After cooling, the product is ejected from the mold.
Advantages of Extruded Blow Molding
There are different types of blow molding processes on the market today. Using extrusion blow molding provides many advantages that include a lower cost for the process. This is one of the reasons our customers choose extrusion blow molding over other types of processes.
However, there are other advantages. At Western Case, we can do short production runs using the extrusion process, we work with less expensive molds, can create different sizes of products, and have a high quality rate with precision.

What’s Involved in Blow Molding Manufacturing?
Creating blow molded products involves manufacturing by which hollow plastic parts are formed and shaped into bottles or containers. What we do next is create a parison, which is a partially shaped mass of molten glass. This is a tube-like piece of plastic with a hole in one end through which compressed air can pass. It is then clamped into a mold and air is blown into it. The air pressure then forces the plastic out to match the mold. After the plastic has cooled down, the hardened mold opens up and drops out.
How We Begin Your Blow Molding Project
Right from the outset, our engineers get involved in an elaborate process in the planning and methodology so that the final stage of production comes out exactly as specified by the customers.
It is important to note that a successful blow molding project starts early on with our highly qualified and experienced engineers. Our engineers will work with your team together with our production, design and marketing staff to ensure that products meet the functional requirements and are manufactured with the top quality material to meet the demands of the customers.
The most basic form of manufacturing blow molding is through the extrusion method.
What is the Extrusion Process of Blow Molding?
The plastic is injected from the extruder as a large tube of molten plastic. This extruded plastic is then molded and set in molds that have been cooled with water. Air is then injected into the molds after they are sealed. This air is introduced from the side in some molds.
Other mold types have an air injection point at the neck of the mold. This air expands the plastic to the inside of the mold to form the material into its proposed ridged shape when it cools. The process resembles the simple process of inflating a balloon inside of various bottles of predetermined shapes and sizes.
How Does an Extrusion Blow Molding Machine Work?
There are extrusion blow mold machines that can produce bottles of various sizes and shapes both in the body of the bottle and in neck sizes at an explosive rate of approximately 350 bottles per hour. This explosive production is facilitated by the machine’s ability to be adjusted in wide ranging, minute, and graduated increments.
The amounts can be as small as grams. These machines are commonly much more economical than injection blow molding machines and can be manufactured much quicker.
Advantages to Extrusion Blow Molding Manufacturing
Other advantages include very high production, less expensive tooling, and they are widely available and through multiple dealers. However, they possess a higher scrape rate and trimming the excess plastic can be difficult. Wall thickness is less controllable in extrusion blow mold machines also, but they are able to process various plastics. Additionally, they require very small startup costs, and many extrusion blow machines can produce very small runs.
