Mold Preheating Furnace – Industrial Mold Thermal Conditioning System | 250-350°C

⚙️ Mold Preheating Furnace | Precision Industrial Mold Heating System by China Ryan

Product Overview

The Mold Preheating Furnace is an advanced industrial mold heating system engineered for accurate and uniform thermal conditioning before production. Operating within a temperature range of 250–350°C, this furnace utilizes electric heating with PID precision control to ensure consistent and reliable mold preparation.

Equipped with a forced convection airflow system, it guarantees even temperature distribution throughout the chamber, eliminating hot spots and minimizing thermal stress. Built with a stainless steel interior and carbon steel exterior, the system offers long service life, stability, and complete customization to meet specific industrial manufacturing needs.

Ideal for molds, dies, spinnerets, extruder die sets, and filter assemblies, the Mold Preheating Furnace enhances productivity and extends the lifespan of critical tooling components.

Technical Specifications

Working Principle

The Mold Preheating Furnace operates through electric heating elements combined with a forced-air convection system. A high-performance blower circulates hot air uniformly within the stainless steel chamber, ensuring even temperature across all mold surfaces.

The digital PID controller monitors and adjusts temperature precisely, while SSR drive control maintains stable heating output. Once molds are loaded, the system gradually increases temperature to the set value, preventing thermal shock and ensuring optimal preheating conditions — readying molds for efficient production use.
