1. Temperature control: A small oven for vehicle car rim coating typically has a digital temperature control system that allows the operator to set and monitor the oven temperature during the curing process. The oven may also have multiple temperature zones to ensure uniform heating and curing.

2. Air circulation: A small oven for vehicle car rim coating typically has a high-volume air circulation system that helps to distribute heat evenly throughout the oven chamber. This helps to ensure consistent curing and reduce the risk of defects in the powder coating.

3. Insulation: A small oven for vehicle car rim coating may have thick insulation to help retain heat and reduce energy consumption. Insulation also helps to prevent heat loss and maintain a consistent temperature inside the oven chamber.

4. Exhaust system: A small oven for vehicle car rim coating typically has an exhaust system that removes excess powder and fumes from the oven chamber. This helps to ensure a safe working environment and prevent contamination of the powder coating.

5. Size and capacity: Small ovens for vehicle car rim coating come in a range of sizes and capacities, depending on the size of the car rims or wheels being coated. These ovens may be designed for small or large rims, and typically have enough capacity to coat several rims or wheels at once.

6. Safety features: Small ovens for vehicle car rim coating may have safety features such as automatic shut-off switches, emergency stop buttons, and safety interlocks to prevent accidents and injuries in the workplace.

Small ovens for vehicle car rim coating are used in the automotive industry to provide a durable and attractive finish on car rims or wheels. These ovens are typically smaller than industrial powder coating ovens and are designed to meet the specific needs of automotive manufacturers and custom coating shops.
