NNK Truck Oil Seal Production Technology and NNK Factory Advantages

As an important part of the sealing system of heavy-duty vehicles, truck oil seals are widely used in key parts such as engines, gearboxes, axles, and wheels. They have extremely high requirements for sealing effect, wear resistance, high temperature resistance, and oil resistance. Its production technology requirements are strict, and every link must be accurate and correct.

1. Truck Oil Seal Production Technology Process:

1. Material Selection

Use high-quality rubber materials (such as NBR, FKM, HNBR, PTFE, etc.) to ensure oil resistance, high temperature resistance, and wear resistance.
The skeleton steel has high precision and good strength to ensure stable structure.

2. Precision mold development

The mold is processed by CNC to ensure accurate size, especially for large-size truck oil seals.
Regular maintenance of the mold prolongs the service life and ensures product consistency.

3. High-precision pressing molding

Use a fully automatic rubber injection molding machine to improve efficiency and product consistency.

Temperature, pressure, and time are strictly controlled to ensure full rubber vulcanization.

4. Automated trimming and assembly

Use an automatic trimming machine to remove burrs to ensure a smooth product appearance.

Precision assembly of metal frames and rubber parts to ensure strong sealing.

5. Testing and quality control

Each batch of products undergoes multiple tests such as size, hardness, elasticity, sealing, dynamic and static friction, etc.

High-speed rotation test simulates actual working conditions to ensure good sealing performance under high temperature and high speed conditions.
