Blow Molded Cases Versus Injection Molded Cases
Blow molded cases, such as those made by Platt
, Western and BMP are ideal in situations where a custom design is necessary because the process of designing the molds is not extensive, time-consuming or prohibitively expensive. At the same time, blow molding creates strong yet lightweight cases that can be used in a variety of situations. Blow molded cases can be manufactured in high or low volumes, and there is a great deal of flexibility associated with designing them. Their high impact resistance makes them ideal for situations where a basic case for a prototype or demo kit is needed.Injection Molded Cases: How They Are Made And Basic Characteristics
With injection molding, thermoplastics are heated up in a barrel then forced into the cavity of a specially-designed mold. Upon cooling and hardening, a strong plastic piece is created. The most involved part in designing an injection molded case is creating the actual mold; that accounts for approximately 90% of the process. For this reason, low volumes of injection molded products are impractical. Consequently, custom cases are not usually designed and manufactured using injection molding. However, this process is ideal for creating high volumes of durable, high quality and stock cases.
The Advantages And Disadvantages Of Injection Molded Cases
Injection molding is ideal for designing and manufacturing a large quantity of standard cases. There are many standard sizes when it comes to shipping cases, carrying cases and other products, so injection molding is frequently used in such applications. Although injection molding is not practical for creating custom cases, the cases that it does produce can include complex designs and intricate features. Generally, injection molded cases are still strong, resilient and versatile.
