Mold heaters are essential in the production of plastics, serving a wide range of applications beyond the common processes of injection molding, extrusion, and blow molding. They play an irreplaceable role in special application fields where precise temperature control is critical. By maintaining consistent mold temperatures, these heaters ensure high-quality and defect-free products, making them indispensable in plastic processing productions.

High-precision Plastic Parts Production

Mold heater is a temperature control unit, maintaining the required temperature of the mold used in plastic processing equipment. Due to the extremely high requirements for dimensional accuracy and surface quality of precise plastic parts, mold heater offers precise and reliable temperature control. 

Through precise temperature control, the mold heater system can ensure that the temperature of the mold remains constant throughout the production process, thus improving the product qualification rate and production efficiency.

Plastic Production of Special Materials

In the production of precision plastic parts, mold heaters are widely used. For example, for high-temperature plastic materials, the mold heater needs to provide a higher heating temperature to ensure that the material can be fully melted and smoothly molded.

For low-temperature plastic materials, the mold heater must provide precise cooling control to prevent the material from deforming or producing defects such as air bubbles due to high temperature during the molding process.

Mold Heater

The mold heater developed by Wensui adopts an advanced microcomputer control system, equipped with a liquid crystal display and key operation interface.

By adopting P.I.D parameter self-tuning bi-directional (heating/cooling) control, its segmented temperature control system ensures the temperature stability of the molds in various states. The temperature control accuracy is as high as ±0.5℃, which significantly improves the production efficiency and product quality.

The Wensui mold heater transfer media is available via water or heat transfer oil. The heaters offer flow rate that ranges from 48 to 470 L/min. Whether you are looking for a temperature control unit via water or oil, we have a wide range of model selections. Reach out to us for more technical details.
