Manufacturing Process of Seal Kits
Every seal kit undergoes a strict production process and testing phase to guarantee long-term reliability:
Precision Material Weighing
Each raw material, including polyurethane, PTFE, and rubber compounds, is accurately weighed according to strict formulation standards. This ensures consistent chemical properties, balanced elasticity, and reliable performance across every seal.
Mold Preparation & Material Placement
High-precision molds are thoroughly cleaned and preheated before material placement. The prepared compound is carefully filled into the mold cavities to avoid defects such as bubbles or uneven density, ensuring flawless shaping of the seals.
High-Pressure Compression Molding
Using advanced compression molding machines, the materials are subjected to high temperature and pressure. This process guarantees excellent dimensional accuracy, uniform density, and the proper hardness required to withstand hydraulic pressure and harsh jobsite conditions.
Rigorous Quality Inspection
Every finished seal undergoes strict inspection procedures, including dimensional checks, surface finish evaluation, and sealing performance tests. Only seals that meet international OEM standards are packaged and delivered, ensuring reliable operation for your machine.
This meticulous process ensures that every seal kit meets or exceeds OEM standards.
Material & Performance
Each O-ring is manufactured from premium-grade NBR (nitrile rubber) and FKM (fluorocarbon rubber, Viton® equivalent) to deliver outstanding sealing performance.
Key Features:
- Oil & Fuel Resistance – Maintains performance even when exposed to hydraulic oils, lubricants, and diesel fuel.
- Temperature Stability – Designed to operate under extreme hot and cold conditions.
- Wear & Pressure Resistance – Capable of withstanding continuous pressure cycles and friction in demanding environments.
- OEM Compatibility – Manufactured to Komatsu specifications, ensuring perfect fit and durability.
