Plastic tank for auto radiator is a lightweight and durable water storage container used to hold coolant as it flows through the radiator. It usually adopts a “top-in, bottom-out” structure, which is responsible for the input and output of the coolant respectively. The water inlet chamber receives the high-temperature coolant, and the water outlet chamber guides the cooled coolant back to the engine circulation to regulate the engine temperature. Unlike traditional metal tanks, plastic tanks are widely used due to their cost-effectiveness, corrosion resistance, and ability to withstand high temperatures.
The Plastic tanks for auto radiator materials mainly use hydrolysis-resistant PA66+GF (glass fiber reinforced nylon 66), and its advantages are as follows:
1. High temperature resistance and hydrolysis resistance
The plastic tank is in contact with high-temperature coolant for a long time (usually the operating temperature can reach above 120°C), and the stability of the material in a high-temperature and humid environment must be guaranteed. PA66 itself has good temperature resistance (melting point is about 260°C). By adding hydrolysis resistance and glass fiber reinforcement, the water absorption rate and degradation rate can be significantly reduced, and leakage problems caused by material expansion or performance degradation can be avoided.
2. High strength and impact resistance
Glass fiber reinforcement significantly improves the tensile strength, modulus and impact resistance of PA66, meeting the structural strength requirements of the automobile cooling system.
3. Dimensional stability
Low water absorption (the water absorption rate can be controlled below 1.5% after modification), coupled with the supporting role of glass fiber, ensures small dimensional changes during long-term use.
4. Lightweight and cost advantages
Compared with traditional metal materials (such as aluminum alloy or cast iron), PA66+GF has a lower density (about 1.3-1.4g/cm³), which can reduce the weight of components by 30%-50%. At the same time, the injection moulding process simplifies the production process and reduces processing costs.
The primary function of the radiator plastic tank is to hold coolant that is continuously circulated between the radiator and the engine block. Here’s a step-by-step breakdown of how it works:
1. Coolant Storage:
The plastic tank stores excess coolant, preventing overheating or freezing of the engine.
2. Heat Exchange Process:
As the engine runs, it generates heat. The coolant absorbs this heat and transfers it to the radiator, where it is cooled before re-entering the engine.
3. Pressure Regulation:
The tank helps maintain optimal coolant pressure, allowing the system to function efficiently.
4. Expansion and Contraction:
The coolant expands and contracts with temperature changes, and the plastic tank accommodates this fluctuation without leakage.
1. Vehicle compatibility
Always check that the plastic tank will fit the specific make and model of your vehicle. Manufacturers often design tanks to the specific specifications of different radiators.
2. Material quality
Choose tanks made of heat-resistant reinforced plastics that can withstand high temperatures and constant contact with coolant chemicals.
3. Pressure rating
Make sure the tank’s pressure rating meets your vehicle’s cooling system requirements. Using a tank with an inappropriate pressure rating may cause system failure.
4. Manufacturer credibility
Our company specialises in providing high-quality products and warranty services to give you added peace of mind.
Using a radiator plastic tank provides multiple benefits, making it the ideal selection for modern vehicles. Some of the key benefits include:
1. Lightweight and Efficient
Compared to metal tanks, plastic radiator tanks are much lighter, which contributes to overall vehicle fuel efficiency and performance.
2. Corrosion Resistance
Unlike aluminum or copper, plastic tanks do not rust, ensuring long-term durability and reducing the need for frequent replacements.
3. Cost-Effective Solution
Manufacturing plastic tanks is more affordable than metal alternatives, making them a cost-effective choice for both vehicle manufacturers and owners.
4. Heat and Pressure Resistance
Modern plastic tanks are engineered to withstand extreme temperatures and pressures, making them highly reliable in various driving conditions.
5. Easy Replacement and Repair
Since plastic radiator tanks are designed to be modular, they can be replaced separately without needing to change the entire radiator, saving on repair costs.
Plastic radiator tanks typically last 5 to 10 years, depending on driving conditions, maintenance, and coolant quality.
Yes, in many cases, the plastic tank can be replaced separately, saving you money compared to replacing the entire radiator.
Regular coolant maintenance, avoiding overheating, and inspecting for wear and tear can help increase the durability of your plastic radiator tank.
While metal tanks are more durable, plastic tanks are lighter, more affordable, and corrosion-resistant, making them a popular choice in modern vehicles.
If you notice a small crack, you can use a sealant as a temporary fix, but replacing the tank is the best long-term solution.
