Blow-Molded Hard Shell Cases
Blow-molded hard cases are an ideal low-cost, lightweight case option,
providing high quality protection and durability.
Quality on a budget
At CH Ellis, we believe smaller budgets should never mean compromised quality. With our blow-molded custom cases, experience the impact of affordable durability.
Blow Molded Cases are your best option for features like:
Lightweight Durability
Blow Molded Cases are designed with a hollow construction, making them extremely lightweight, yet strong enough to resist impact. Plastic is melted and formed into a tube, which is then inflated into a mold using air pressure. The air gap in case walls provides natural cushioning during impact, making them an ideal choice for toolboxes, carrying cases, and consumer-grade cases.
Low
Cost
For high-volume production, blow molding is often the most cost-effective option. Compared to injection and rotomolding, it runs on faster cycle times, and uses less material per case.
Seamless Hinges and Unique Designs
Blow molded cases feature integrated hinges, handles, and other functional details directly in the molding process. This results in minimal assembly, streamlined connections, and less potential points of failure.
Customization
While injection and rotomolded cases can also be customized, blow molding allows for custom shapes and designs that are lightweight and ergonomic
Weather Resistance
At CH Ellis, our blow molded cases are made from HDPE (high-density polyethylene) and ideal for outdoor use, as they are resistant to water, chemicals, and UV light.
