The equipment is suitable for vulcanization molding of various rubber molded and non-molded products, widely used in mass production of sealing rings, O-rings, oil seals, silicone keypads, automotive rubber parts, vibration-damping bushings, thermosetting plastics, composite materials, and more. The platen size is 750×850mm, with adjustable platen gap ranging from 500 to 900mm, flexibly accommodating molds of different heights to meet the production needs of multiple product varieties and specifications.
Automatic Program Sequence: Pull up the manual control lever → Motor starts → Low-pressure rapid closing → High-pressure pressing → Vulcanization timing (with automatic pressure compensation) → Alarm at timing completion → Pull down the manual control lever to open.
Structural and Performance Advantages: The machine features good rigidity and stable load-bearing capacity. The four-column structure with columns provides excellent overall rigidity and strong resistance to eccentric loads. Under the rated 200-ton pressure, frame deformation is minimal, effectively protecting mold precision and extending mold service life. All moving parts maintain proper fitting clearances, ensuring sustained mold alignment accuracy over long-term use. The hydraulic system is mature in design with reliable pressure holding. The main cylinder has a diameter of Φ400mm with a system rated working pressure of 16MPa. The hydraulic circuit features pressure-holding design with pressure drop not exceeding 10% within one hour. Automatic pressure compensation during vulcanization ensures constant pressure throughout the process without manual intervention, effectively guaranteeing consistent product dimensions and density uniformity. High temperature control accuracy with minimal platen temperature variation. PID intelligent temperature controllers provide closed-loop regulation of platen temperature with high control accuracy and good surface temperature uniformity across the platen. Maximum heating temperature reaches 300℃, covering the temperature requirements of mainstream processes including rubber, silicone, thermosetting plastics, and composite materials. Ample working space with wide applicability. The effective platen area measures 750×850mm with a unit pressure of 3.13MPa and uniform pressure distribution. The platen gap is continuously adjustable from 500 to 900mm, easily handling both high-speed pressing of thin products and prolonged vulcanization of thick molds. One machine serves multiple purposes, particularly suitable for production scenarios involving numerous product specifications. Compact layout with convenient operation. The entire machine adopts an integrated three-in-one layout of main frame, hydraulic station, and control cabinet, with a centralized operator station. A single operator can complete the entire process of closing, pressing, vulcanization timing, and mold opening. The manual control mode is intuitive and reliable, with convenient maintenance and inspection, allowing operators to become proficient quickly.
Safety and Auxiliary Functions: The equipment comes standard with an emergency stop button for one-touch shutdown in emergency situations. The vulcanization timer automatically triggers an audible and visual alarm upon reaching the set time, preventing product quality issues caused by over-curing or under-curing. The hydraulic system is equipped with automatic pressure compensation to ensure stable pressure throughout the vulcanization process. Interlock protection between all actions effectively prevents operational errors.
Customization and Upgrade Options: Based on actual production requirements, the following functional modules can be flexibly selected:
Push-Pull Mold Mechanism: Facilitates loading and unloading of large and heavy molds from the platens, reducing operator labor intensity
Forced Mold-Opening Device: Suitable for demolding foamed products or materials prone to sticking
PLC with Touchscreen Control System: Enables semi-automatic/full-automatic programmed operation, stores multiple process parameter groups, supports one-touch recall
Safety Light Curtain Protection Device: Further enhances operator safety
