PLC Automatic Mold Opening Rubber Vulcanizing Machine / Insulating Rubber Pad Making Machine


A rubber insulation pad vulcanizing machine is specialized equipment used to manufacture rubber insulation pads through the vulcanization process. Vulcanization involves heating raw rubber with sulfur or other curatives under pressure to improve its elasticity, strength, and thermal resistance, making it suitable for electrical insulation applications.

Key Features of a Rubber Insulation Pad Vulcanizing Machine:

1. Heating System

   • Uses electric heating plates, steam, or oil to maintain precise temperature control (typically 140°C–200°C).

   • Ensures uniform heat distribution for consistent vulcanization.

2. Hydraulic or Mechanical Press

   • Applies high pressure (usually 10–20 MPa) to ensure proper bonding and eliminate air bubbles.

   • May feature automatic or semi-automatic operation.

3. Mold System

   • Customizable molds for different pad thicknesses and shapes (e.g., flat, ribbed, or textured surfaces).

   • Made from high-strength steel for durability.

4. Control System

   • PLC (Programmable Logic Controller) or microprocessor-based for automated temperature, pressure, and time settings.

   • Touchscreen interface for easy operation.

5. Cooling Mechanism

   • Some machines include cooling stages to stabilize the vulcanized pads before demolding.

6. Safety Features

   • Overpressure protection, emergency stop, and thermal sensors for safe operation.

Applications of Rubber Insulation Pads:

• Electrical insulation for switchgear, transformers, and power distribution systems.

• Anti-vibration pads for machinery and equipment.

• Slip-resistant flooring in industrial environments.

Types of Vulcanizing Machines for Rubber Pads:

• Flat Plate Vulcanizing Press – Suitable for standard flat insulation pads.

• Frame Type Vulcanizing Press – For thicker or larger pads.

• Automatic Vulcanizing Line – For mass production with conveyor feeding.

Considerations When Choosing a Machine:

• Production capacity (batch size and automation level).

• Material compatibility (EPDM, silicone, nitrile rubber, etc.).

• Energy efficiency (electric vs. steam heating).

• After-sales support (maintenance, spare parts availability).

• Insulation rubber pad use

• As an important industrial material, insulating rubber pads play an indispensable role in various fields. So, what kind of industrial and commercial classification does the insulating rubber pad belong to? Next, we will introduce it in detail from the aspects of material, function and use.

• 1. Industrial and commercial classification of insulating rubber pads
  The industrial and commercial classification of insulating rubber pads can be considered from two aspects: material and function.
  Material classification
  The materials of insulating rubber pads are varied, and the common ones are natural rubber, silicone rubber, fluororubber, chloroprene rubber, etc. These insulating rubber pads of different materials have their own characteristics in performance, such as temperature resistance, oil resistance, acid and alkali resistance, etc., to meet the needs of different industries.
  Functional classification
  According to different functions, insulating rubber pads can be divided into insulating type, anti-slip type, shockproof type, etc. Insulating rubber pads are mainly used for insulation protection in the electronics, electrical, power and other industries; anti-slip rubber pads are widely used in machinery manufacturing, automobile maintenance and other fields to improve operational safety; shockproof rubber pads are mainly used for shock absorption protection of precision instruments and equipment.
  2. Application fields of insulating rubber pads
  Insulating rubber pads are widely used in both industrial and civil fields. Here are some of the main application areas:
  Electronic and electrical industries
  In the electronic and electrical industries, insulating rubber pads are widely used as insulating and protective materials for the insulation protection of components such as circuit boards, switches, and sockets. It can effectively prevent short circuits and leakage between electrical components and ensure the normal operation of electrical equipment.
  Power industry
  In the power industry, insulating rubber pads are used as insulating materials for cable accessories, busbar bridges and other equipment, and have excellent insulation and temperature resistance. It can effectively isolate power equipment of different voltage levels to avoid electrical safety accidents.
  Machinery manufacturing industry
  In the machinery manufacturing industry, insulating rubber pads are mainly used for shockproof, anti-skid and protection of equipment such as machine tools and molds. It can reduce the vibration and noise generated by the equipment during operation and improve the stability and service life of the equipment.
  Civil fields
  In addition to the industrial field, insulating rubber pads are also widely used in the civilian field. For example, in household appliances, insulating rubber pads can be used as insulating and protective materials for power plugs, sockets and other components; in automobile maintenance, insulating rubber pads can be used for shockproof, anti-skid and protection of automobile chassis, engines and other parts.
  In short, as an important industrial material, insulating rubber pads play an indispensable role in various fields. Understanding the industrial and commercial classification and application fields of insulating rubber pads will help us better select and use this material and provide strong support for the development of various industries.
