Mold Heater: Water vs. Oil Transport Types

injection molding machine heater

Mold heater play a crucial role in various industries such as plastic molding, die-casting, and rubber tire manufacturing.

They come in two main types: water-type and oil-type controllers.

These injection molding machine heater serve as constant temperature heat sources, offering both heating and cooling functions. The primary function of a injection mold temperature controller is to regulate the equilibrium temperature of heat-using equipment, ensuring it reaches and maintains the required temperature for the manufacturing process. Utilizing heat-conducting media with high thermal conductivity, these controllers swiftly adjust the equipment’s temperature, minimizing errors and sustaining a stable temperature. Comprising heating and cooling systems, power transmission mechanisms, liquid level control, temperature sensors, and injection ports, mold temperature control machine operate efficiently. The system’s pump transports hot fluid from the unit’s built-in heaters and coolers to the heating equipment. Once the heat is absorbed, the fluid returns to the controller for reheating.

Temperature sensors monitor the fluid’s temperature, transmitting data to the controller for adjustment, indirectly controlling the equipment’s temperature. Safety is paramount when using mold temperature controllers, especially oil-type ones. Operators must adhere to safety regulations, such as maintaining a safe distance from heat sources and using leak-proof and temperature-resistant hoses or pipes. Regular checks on the temperature control loop, joints, and fluid replacement are essential to ensure optimal performance and safety.

Choosing the right heat transfer fluid is critical for efficient operation.

Water type mold heater:Water, known for its economy and cleanliness, is commonly used. However, it has limitations, such as a low boiling point, restricting its temperature range. Precautionary measures like pre-treating the control circuit, using filters, and regular cleaning are necessary for water-based systems.

Oil type mold heater:Oil-based systems offer higher operating temperatures, reaching up to 350 ° C, with better thermal stability. However, their heat transfer efficiency is lower compared to water.

In conclusion, mold heater, whether water or oil transport types, enhance product quality, reduce defects, improve production efficiency, and minimize energy consumption, contributing to overall cost-effectiveness in manufacturing processes.
