Product Description

400-Ton Pressure Flat Frame Vulcanizing Machine

Used to produce high-strength rubber cord fabric sandwich rubber sheets for demanding industrial applications.

Understanding Rubber Cord Fabric Sandwich Sheets

This is not a simple rubber sheet but a reinforced composite laminate with a specific layered structure:

Bottom Layer: Thick sheet of uncured rubber compound
Core Layer: Cord fabric or breaker fabric - parallel arrays of high-tensile synthetic cords bonded with rubber skim coat
Top Layer: Another thick sheet of uncured rubber compound

The vulcanization process bonds these three layers into a single, inseparable, high-strength sheet with perfectly embedded fabric reinforcement.

Why 400-Ton Flat Frame Vulcanizing Press is Essential

Immense Pressure for Proper Bonding & Void Elimination

The 400-ton force ensures complete penetration and encapsulation of every cord in the fabric, eliminating air pockets and achieving the uniform density required for optimal mechanical properties.

Critical Parallelism and Deflection Control

The flat frame or four-post design provides superior rigidity over C-frame presses, maintaining perfect platen parallelism under 400 tons of pressure to ensure uniform density and bonding across the entire sheet surface.

Precise Thickness Control

Spacer bars and precise stroke control work in conjunction with high pressure to guarantee consistent sheet thickness across all production runs.

Manufacturing Process Overview

Step 1: Material Preparation

Rubber compounds are mixed and calendered to precise thickness, while pre-treated cord fabric is cut to size with careful attention to cord alignment and tension.

Step 2: Lay-Up (Building the "Sandwich")

A manual or semi-automatic process involving sequential layering:

Release film placed on metal loading tray
Bottom rubber sheet positioned
Cord fabric carefully placed without wrinkles
Top rubber sheet added
Final release film applied

Step 3: Vulcanization

The loaded stack enters the press, which applies full 400-ton clamping force while heating platens to cure temperature (150-180°C). Time, temperature, and pressure are precisely controlled via PLC.

Step 4: Demolding and Finishing

After curing, sheets are removed from release films, inspected for defects, trimmed if necessary, and tested for critical properties including adhesion strength and tensile performance.

Key Quality Considerations

Adhesion (Peel Strength): Optimal bond between rubber and cord fabric
Cord Integrity: Protection against crushing or distortion under pressure
Uniformity: Consistent pressure and temperature distribution to prevent soft spots

Industrial Applications

These vulcanized sandwich sheets serve as critical semi-finished materials for:

Steel cord reinforced conveyor belt splices
Conveyor belt repair materials
Reinforcement sections for high-pressure hoses
Composite rubber/textile structural components

The 400-ton Flat Frame Vulcanizing Machine provides the simultaneous, uniform, and extreme pressure and heat required to transform rubber and cord fabric layers into homogeneous, high-strength engineered composite sheets for critical industrial applications.
