Our Large Injection Molding Machine is engineered for high-efficiency, high-precision rubber molding, making it ideal for manufacturing a wide range of rubber components in industries like automotive, electronics, and medical devices. This state-of-the-art machine is designed with advanced features to ensure exceptional performance, durability, and cost-effectiveness.
Key Features:
-
Hydraulic System with Servo Motor Control
The hydraulic system is powered by four sets of high-performance servo motors, delivering a flow rate of 100L/min. This system ensures stable pressure, precise adjustment, and significant energy savings, resulting in long-lasting and consistent performance. -
Comprehensive Heating Plate Setup
The machine comes with a complete set of heating plates, including the upper heat insulation plate, cold runner plate, middle heat insulation plate, upper heating plate, lower heat insulation plate, and lower heating plate. This system guarantees efficient heat distribution, ensuring uniform curing of rubber materials. -
Vacuuming and Exhaust Control
Equipped with a vacuuming device that offers individual control of vacuuming time, this machine ensures optimal evacuation of air and gases during molding. Additionally, the multi-stage exhaust program (optional) provides extra precision in managing the molding environment. -
Independent Control of Mold Clamping and Opening
The clamping pressure, speed, and stroke of the mold are all separately controlled, allowing for precise mold operations and reducing wear on the mold components. -
Precise Vulcanization Control
Both the vulcanization time and temperature are independently controlled, ensuring optimal curing conditions for various rubber materials, improving product consistency and quality. -
Advanced Injection Control
The machine allows separate control of injection material volume, injection pressure, injection time, injection speed, and the number of injection segments, providing the flexibility to produce complex, high-quality parts. -
Double-Cylinder Injection System
Featuring a large oil cylinder with double-cylinder injection, the system ensures strong injection force and stable, reliable injection volume for consistent quality and performance across high-demand production runs. -
Precision-Cast Composite Clamping Cylinder
The precision-cast composite clamping cylinder design provides large clamping force, reducing product burrs and enhancing the overall molding process, delivering clean, precise rubber components. -
Mold Temperature Control
The barrel temperature is controlled by a mold temperature machine, ensuring fast heating and cooling capabilities, with precise control to guarantee the perfect mold temperature throughout the injection process.
