Engineered for Durability and Precision

We understand the critical role these components play in the field. Our seals are not just replacements; they are engineered for superior reliability and long-term durability. We use high-grade materials to ensure our kits can handle the most demanding conditions, from high-impact work to extreme temperatures.

Each component in our kits is manufactured to strict specifications, guaranteeing a perfect fit and seamless integration with your Toku hydraulic breaker. This precision ensures that your hydraulic breaker operates efficiently, reducing the risk of leaks and system failures.

Our Manufacturing Excellence

Every seal kit is the result of a rigorous manufacturing process focused on precision and quality control.

Precision Material Weighing

Precision Material Weighing

Each raw material block is carefully weighed with high-accuracy equipment before processing. This ensures that every seal ring starts with the exact material volume required for its specific size and application, preventing inconsistencies in density or performance.

Mold Preparation & Material Placement

Mold Preparation & Material Placement

After weighing, the prepared material is positioned onto the appropriate mold. Our workshop is equipped with a wide variety of molds to match different seal ring diameters and cross-sections. The correct mold selection guarantees precise shaping, while careful placement avoids defects such as uneven thickness.

High-Pressure Compression Molding

High-Pressure Compression Molding

The molds are then set under specialized compression machines, where controlled pressure and temperature are applied. This process allows the material to be fully formed into a durable seal with consistent hardness and elasticity. Strict monitoring ensures every batch meets dimensional accuracy and structural integrity.

Seals Rigorous Quality Inspection

Rigorous Quality Inspection

Each batch of seals undergoes rigorous testing after molding. Technicians check for dimensional accuracy, surface smoothness, hardness, and sealing resilience. Any defective products are filtered out, ensuring that only seals with stable performance and long service life proceed to packaging.

Seal Placement

Seals are strategically installed in piston, cylinder, valve, and tie rod areas of breakers. They work together to:

  • Prevents leakage of hydraulic oil under high pressure.
  • Protecting internal components from dust, water, and abrasive particles.
  • Provides smooth piston and connecting rod movement and consistent impact force.
  • Reduces wear on metal components by maintaining proper lubrication.

Seals are strategically placed in the piston, cylinder, tie rods, and valve areas, ensuring full hydraulic protection and preventing premature wear of critical components.
