100-ton Pressure Rubber Vulcanizing Machine with 800×800 Worktable and 4 kW

Product Specification

100-ton Pressure Rubber Vulcanizing Machine / 800×800 Worktable

Overview

This is a Hydraulic Press designed to apply immense heat and pressure to raw rubber compounds inside a mold. This process, called vulcanization, transforms the soft, plastic-like raw rubber into a strong, elastic, and durable final product.

The key specifications "100-ton" and "800x800 worktable" tell us about its force and size, which are critical for determining its applications.

1. Key Specifications Explained

• 100-ton Pressure (1000 kN):

  • This refers to the clamping force the machine can generate.

  • It means the press can exert a force equivalent to 100 tons (or approximately 1,000 KiloNewtons) to keep the mold closed during the vulcanization process.

  • Why it matters: This force is necessary to counteract the internal pressure generated when the rubber heats up and flows, preventing flash (excess rubber seeping out of the mold) and ensuring the part is formed with precise dimensions and density.

• 800x800 Worktable (800mm x 800mm):

  • This is the size of the platen—the heated steel plate that the mold sits on.

  • An 800x800 mm (approximately 31.5 x 31.5 inches) platen defines the maximum mold size that can be accommodated.

  • Why it matters: This determines the maximum size of a single part you can produce or the number of smaller parts you can mold in one cycle (using a multi-cavity mold).

2. Typical Components and Features

1. Frame: A robust structure (often a C-frame or four-column frame) to withstand the 100-ton force.

2. Hydraulic System: Consists of a hydraulic pump, cylinder, and valves to generate and control the pressing force.

3. Heating Platens: The large, flat, heated steel plates (the bottom one is the "worktable"). They are typically heated by:

   • Electric Heating Rods: Most common, easy to control.

   • Steam Heating: For larger, industrial applications.

   • Hot Oil: For very uniform temperature distribution.

4. Control System: A programmable logic controller (PLC) and temperature controller to automate the process. It allows operators to set parameters like:

   • Temperature (typically 150°C - 200°C / 300°F - 400°F)

   • Pressure (the 100-ton force)

   • Curing Time (the duration of heat and pressure)

5. Safety Features: Includes light curtains, two-hand controls, and mechanical guards to protect operators.

3. Common Applications

This machine is a workhorse in the rubber industry for producing a wide variety of medium-to-large sized rubber products:

• Rubber Mats & Flooring: Anti-fatigue mats, elevator mats, rubber tiles.

• Automotive Parts: Engine mounts, gaskets, seals, bushings, diaphragms.

• Industrial Products: Conveyor belt splices, rollers, seals, grommets, shock absorbers.

• Silicone Products: Kitchenware (spatulas, baking mats), medical components, seals.

• Footwear: Rubber soles and heels.

4. Advantages of this Specific Size

• Versatility: The 100-ton force and 800x800 mm platen make it a great mid-range machine, capable of handling a very wide array of products without being overly massive.

• Efficiency: It can produce large single parts or multiple smaller parts per cycle, making it efficient for both batch and medium-volume production.

• Precision: Provides sufficient pressure to produce high-quality, flash-free parts with good detail and consistent physical properties.

Summary

In short, a 100-ton, 800x800 rubber vulcanizing machine is a versatile and powerful hydraulic press designed to transform raw rubber into finished, durable products by applying precise heat and pressure. Its specifications make it ideal for manufacturers needing to produce a wide range of medium-sized, high-quality rubber components.
