YIZUMI Intelligent Solutions for Deep-Cavity Injection Molding Production

Deep-cavity injection molding is one of the more demanding processes in plastic manufacturing. Producing components such as trash bins, large plastic containers, outer barrels, and household items with deep cavities requires not just precise mold filling but also high stability and powerful clamping force. For manufacturers seeking consistent quality and efficient production cycles, the choice of injection molding equipment directly determines competitiveness and profitability.

YIZUMI, a global manufacturer of intelligent injection molding and die casting systems, has been committed to redefining how manufacturers approach deep-cavity plastic molding. With its advanced LS Series hydraulic injection molding machines, YIZUMI provides a reliable solution tailored for large, deep, and complex molded products—combining stability, precision, and automation readiness.

The Challenge of Deep-Cavity Injection Molding

In deep-cavity injection molding, the mold design features narrow and elongated geometries that make it challenging for molten plastic to flow evenly and fill the cavity completely. The pressure and temperature distribution must be meticulously controlled to avoid issues like sink marks, short shots, and warping.

A key challenge also lies in demolding. Deep parts tend to stick or deform during ejection, requiring a longer opening stroke and precise control of the clamping and ejector system. Furthermore, the process often involves large molds and high tonnage, demanding machines with optimized clamping systems and enhanced rigidity.

Manufacturers aiming for large-volume production of deep-cavity products—such as trash cans, logistics containers, or industrial barrels—need injection molding machines that can handle high-speed cycles without compromising dimensional accuracy. Stability, energy efficiency, and ease of automation have become central decision factors for industrial businesses.

Why Intelligent Injection Molding Equipment Matters

Intelligent injection molding equipment has changed the landscape of industrial plastic manufacturing. Instead of relying on manual adjustment and operator experience, modern systems use servo control, digital monitoring, and data-driven optimization to ensure consistent results.

For deep-cavity molding, these intelligent systems help to:

Ensure precise filling through real-time control of injection speed and pressure.
Reduce material waste by minimizing flash and improving the uniformity of clamping force.

Shorten cycle time with efficient mold opening and closing sequences.

Enhance stability and repeatability, crucial for long-term production of large molded parts.

Integrate with automation systems, enabling in-mold labeling, robotic take-out, and stacking for improved production efficiency.

These benefits not only lower production costs but also help manufacturers maintain a consistent product standard across large batches—something increasingly critical in competitive consumer and industrial markets.

YIZUMI’s LS Series: Designed for Deep-Cavity Product Manufacturing

At the heart of YIZUMI’s intelligent solution for deep-cavity injection molding lies the LS series toggle-clamping hydraulic injection molding machine. This machine was developed to overcome the typical limitations faced when molding large and deep components.

The LS series injection molding equipment introduces an outward toggle clamping unit—a new configuration that significantly enhances the mold opening stroke, providing 25–35% more opening distance than conventional clamping systems. This feature is essential when producing deep-cavity items, allowing smooth demolding and facilitating integration with automation, such as in-mold labeling or robot pick-up systems.

Large-stroke clamping unit

High Stability and Centralized Clamping Force

One of the LS series’ deep-cavity injection molding machine standout features is its clamping force distribution. Instead of spreading unevenly across the platen, the force focuses on the platen center, effectively reducing deformation during high-pressure cycles. This precision in clamping helps maintain tight tolerances, improves product surface quality, and reduces flash defects.

By optimizing the use of clamping force, the LS series injection molding machine minimizes unnecessary mechanical wear and energy loss—an important advantage for factories operating multiple shifts or high-tonnage machines. Over time, this leads to reduced maintenance costs and more reliable operation.

Large Opening Stroke for Complex Molds

Deep-cavity molding requires extensive opening strokes to eject large or tall products safely. The LS series injection molding equipment offers 25–35% larger opening strokes than typical toggle-clamping units. This enhancement supports flexible mold designs and makes the machine adaptable for diverse product dimensions—from tall trash cans to industrial storage drums.

This design also makes the LS series injection molding machine particularly suitable for manufacturers who require high throughput with minimal downtime, as molds can be opened and closed swiftly without compromising alignment or safety.

Optimized for Speed and Smooth Operation

The LS series deep-cavity injection molding machine achieves high-speed cycles and stable operation through its optimized outward toggle structure. The improved velocity ratio enables faster clamping and unclamping, reducing the overall dry cycle time.

Equipped with a proportional valve and procedural closed-loop control, the machine ensures smooth and stable mold movements, even during high-speed operations. This level of control is vital for maintaining consistent part quality in deep-cavity production, where minor variations in mold speed or pressure can impact the final product dimensions.

Servo system for deep-cavity injection molding machine

Fourth-Generation Servo System for Energy Efficiency

Energy efficiency remains a top concern for injection molding operations. YIZUMI’s LS series injection molding equipment integrates its proven fourth-generation servo system, delivering fast response times and precise hydraulic control.

This system combines low noise, strong power, and significant energy savings compared to traditional hydraulic systems. By optimizing motor output according to real-time load conditions, the LS series deep-cavity injection molding machine reduces idle energy consumption—helping manufacturers achieve both cost savings and sustainability goals.

Upgraded KEBA Control System for Precision

The LS series injection molding equipment is equipped with the upgraded KEBA control system, allowing more accurate monitoring and regulation of critical process parameters such as pressure, flow, position, and temperature.

For deep-cavity injection molding, such precise control directly translates into better repeatability and higher surface quality of molded products. The advanced system stability also minimizes production variability, ensuring smooth and reliable performance even under demanding workloads.

Automation-Ready for Future Manufacturing

Modern injection molding production is increasingly automated, and YIZUMI has designed the LS series deep-cavity injection molding machine to integrate seamlessly with robotics and auxiliary equipment.

From in-mold labeling (IML) to robot-assisted pick-up and stacking, the LS series injection molding equipment supports full automation setups that enhance production safety, efficiency, and consistency. Manufacturers benefit from reduced labor costs, faster changeovers, and the ability to maintain stable output across shifts.

This automation readiness positions the LS series injection molding machine as a forward-looking solution for companies seeking long-term scalability and smarter factory layouts.
