The Differences Between Blow Molded and Injection Molded Cases

Extrusion Blow Molded Carrying CasesBlow 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
• Electrical insulation and flame resistance properties

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.

how-blow-molding-creates-quality-auto-plastic-products

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
– In-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.

How Does Blow Molding Work To Create Products?

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.

The Advantages and Disadvantages of Using Blow Molding for Plastic Products

Advantages of Using Blow Molding

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.

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.

Discover the Process of Extrusion Blow Molding

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.
