In the race for efficiency, traditional two-platen and stack molds often hit a ceiling. The next leap in high-volume production technology is Cube Injection Molding, a groundbreaking technique that doubles your effective cavitation and drastically cuts cycle times.

The core innovation of the Cube Injection Molding system is its ability to utilize four mold faces—two on the fixed side and two on the movable side—in a coordinated sequence. In one cycle, the machine can simultaneously:
Inject plastic into the molds on the inner faces.
Cool the parts on the outer faces.
Eject the finished parts (usually via a rotary mechanism).
Close the newly empty molds for the next injection.
By performing four distinct operations in the time it usually takes for one standard cycle, manufacturers can effectively double the output without increasing the machine's footprint, making it the highest density production solution available today.
The rotational mechanism of the cube mold is perfectly suited for complex, multi-component parts, such as those requiring two materials (2K) or two different colors. The two opposite mold faces can be used to perform the first injection (e.g., the rigid core), and the subsequent 180-degree rotation moves these pre-formed parts to the next set of cavities where the second material (e.g., a soft TPE grip or a different color) is injected. This eliminates the need for part handling or a secondary molding machine, drastically simplifying assembly and improving part quality by ensuring perfect alignment between the components.
While the initial tooling investment for Cube Injection Molding is higher than conventional molds, the return on investment is swift and significant. The primary cost savings are derived from:
Optimized Cooling Time: The parts spend half the total cycle time in the cooling phase on the outer faces, but the machine can inject again much sooner, as the cooling is happening in parallel with injection.
Reduced Machine Size: Because the cube utilizes four faces, a manufacturer can achieve the output of two conventional stack molds using a single machine with less clamping force (due to lower projected area). This saves on capital expenditure, utility costs, and factory space.
