Lab 20/30/50 Tons Intelligent Force Control Hydraulic Plate Vulcanizing Press System For Rubber Molding
Overview
This series of plate vulcanizing presses is primarily used for molding various rubber model and non-model products. It can also be employed for pressing thermosetting plastics and foamed rubber-plastic products. Equipped with independent power mechanisms and electrical systems, the machine adopts centralized button control. Both working pressure and heating temperature can be adjusted within a certain range. This model is available in manual and semi-automatic versions.
Heating Plate Features
Made of imported high-temperature-resistant steel, the surface undergoes deep carbonization, hard chrome plating, and other processes, ensuring fast heat transfer, rapid cooling, corrosion resistance, high hardness, and minimal deformation. The built-in heaters and temperature sensors at the back provide high power, quick heating, sensitive and uniform temperature measurement, and a small temperature error range.
Guide Columns
Four hardened and precisely positioned columns, along with hydraulic cylinders, are supported by a thick steel plate base of the entire control box. The hydraulic platform slides smoothly and noiselessly on self-lubricating bronze bearings along the columns. The top and rear of the press are enclosed with heavy-duty steel, providing additional safety protection for operators. The upper layer consists of steel plates with built-in thermocouples inserted near the surface.
Features
1. The equipment adopts a four-column, three-plate steel structure, with the moving plate parallel to the working surface and precision guide sleeves fitted to the four columns, ensuring high accuracy.
2. Parameters such as pressure, stroke, speed, and pressure holding time can be adjusted according to the pressing process requirements.
3. It utilizes Taiwanese-brand pneumatic and electrical components along with Japanese NOK seals, ensuring long-term durability.
4. The upper and lower heating plates feature independent temperature control via RKC intelligent temperature controllers, with a precise temperature control accuracy of ±1°C.
5. Equipped with hands control and an emergency stop button for easy mold installation and adjustment, ensuring high safety.
6. The worktable is fitted with casters and foot cup mounts below, allowing effortless and efficient mobility.
7. Optional safety photoelectric protection device is available for a user-friendly and safer operation.
8. Customization is available for special requirements such as non-standard worktable dimensions and high-pressure models.
