What are the Key Features of Temperature Controller? 

mold temperature controllers

Temperature controller serve the vital function of heating molds and maintaining their operational temperature, ensuring consistent quality of injection molded parts while optimizing processing efficiency. In the realm of injection molding, mold temperature significantly influences both the quality and production time of molded parts.

The primary objective of mold temperature control is twofold: first, to elevate the mold to its optimal working temperature, and second, to sustain that temperature consistently during operation. Achieving these goals leads to optimized cycle times and the maintenance of high-quality molded parts. Mold temperature exerts considerable influence on surface finish, material flow, shrinkage, injection cycles, and dimensional stability. Higher mold temperatures generally enhance surface finish and material flow but extend cooling and molding cycles, while lower temperatures can reduce mold shrinkage but may increase post-molding part shrinkage. For thermosetting materials, higher mold temperatures typically decrease cycle times, primarily determined by cooling durations. Moreover, elevated mold temperatures in plastic processing can shorten plasticization times and increase production efficiency.

Key Characteristics of Temperature جيمontrollers: 

  1. Temperature Range: Temperature control machines are available in various models with temperature ranges typically spanning 90, 120, 150, and 180 degrees Celsius.

  2. Heat Transfer Medium: Water serves as the primary heat transfer medium in temperature control machines. Compared to heat transfer oil, water boasts higher specific heat capacity and faster heat transfer rates, resulting in superior mold heating performance under identical operating conditions. 

  3. Ease of Use and Environmental Friendliness: Temperature control machines utilize water as the circulating medium, requiring only water circulation with specific water pressure. This setup offers ease of operation and generates zero pollution. Rapid Cooling: One notable advantage of water-based temperature control machines is their rapid cooling capability. Employing direct cooling methods, where cooling water directly enters the heat exchange pipes, facilitates swift temperature reduction in the system. 

  4. Maintenance and Cost Efficiency: Unlike systems reliant on thermal oil, water-based temperature control machines eliminate issues associated with prolonged oil usage and the need for periodic replacement due to degradation. These machines offer comparable efficiency at a lower cost, as there’s no requirement for purchasing and replacing heat transfer oil. Additionally, water sampling for maintenance purposes is straightforward and cost-effective. 

  5. Limitations: Despite their merits, water-based temperature control machines have limitations. Water’s boiling point under atmospheric pressure is 100 ° C, although, in a pressurized system, it can exceed 180 ° C. However, this necessitates robust pressure-resistant molds and equipment, elevating costs associated with system components compared to oil-based counterparts.
