Precision Injection Molding with Faster Cycle Times and Longer Tool Life
We installed the Shibaura EC85SXIII injection molding machine to take advantage of its rapid production speeds and dry cycle times, as well as a multitude of features designed to provide better repeatability and an extended service life from the mold tooling.
As we discuss below, all-electric machines offer a number of advantages in speed and precision by design when compared to their hydraulic counterparts. However, Elite’s new EC85SCIII setup integrates some uniquely innovative features of its own which will further enhance our contract manufacturing services and rapid injection molding (RIM) capabilities.
Machine Highlights, Features, and Specifications:
5-Point Toggle Mechanism for Even Load Distribution
The EC95SCIII features a unique 5-point toggle mechanism that is precisely angled to evenly distribute force across the machine’s platen. By keeping load distribution equal, we can further assure the quality of your custom molded plastics while minimizing defects and rejected parts.
Extended Service Life of Mold Tooling
The 5-point toggle mechanism’s even force distribution has the added benefit of extending the service life of the mold and tooling. There’s simply less stress and variance introduced into the system, which also minimizes overall machine maintenance.
Integrated Strain Gauge Automatically Adjust Tonnage
A strain gauge is integrated into the tie bar mechanism to monitor force in real time and make automatic adjustments. As opposed to some hydraulic machines which are only capable of pressing at a constant force, our Shibaura setup can provide on-the-fly adjustments to ensure the optimum force is applied at all times.
Grease-Free Tie Bars and Busingless Guides for Rigidity and Precision
Many conventional injection molding machines use bushings and greased slides within their drive systems, introducing the risk of contamination while also requiring complex machine maintenance. The EC95SCIII utilizes friction-free linear guides instead of tie bar bushings, as well as within the injection unit, thus ensuring smooth, accurate injection speed, highly precise back pressure control, and the ultimate level of repeatability for plastic molded parts.
The Advantages of an All-Electric Injection Molding Machine:
- Increased Accuracy and Repeatability for Molded Products – Modern hydraulic injection molding machines, while incredibly advanced and precise, still rely on complex hydraulic systems composed of numerous pumps, valves, and hoses, valves and pumps. All of those components working together to control fluid dynamics means there is always a chance of slight variance in results. In contrast, all-electric injection molders are equipped with computer-controlled servo motors – every movement is digitally monitored and controlled with precision.
- Reduced Energy Consumption – Despite what the name may suggest, all-electric injection molding machines are relatively energy-efficient when compared to hydraulic options. The complex hydraulic systems actually require more energy to actuate, and they can’t be completely turned on/off instantly like electric systems. At Elite, energy-efficient machines and processes are just a small part of our commitment to sustainable injection molding services.
- A Cleaner, Cooler, Oil-Free System – The oil that powers conventional hydraulic injection molding machines adds an additional layer of complexity and potential uncleanliness on the factory floor. Even small oil leaks can lead to contamination and/or unsafe working conditions, requiring immediate maintenance and downtime. All-electric injection molding machines forgo the use of complex hydraulic pumps and pressurized oil systems. Additionally, hydraulic molding machines generate substantial heat and thus require constant cooling. That causes the oil to degrade over time, so you have to perform potentially messy oil changes in the factory. All-electric machines naturally run much cooler and therefore eliminate the use of oil-cooling systems.
