Dongguan mold temperature control machine, also known as mold temperature control machine, is widely used in the temperature control of plastic molding, light guide plate, die casting, extrusion, extrusion, rubber tires, rollers, chemical industry, reaction kettle, adhesive, internal mixing, and other industries. In a broad sense, it should be called a temperature control device, including two aspects of temperature control: heating and freezing. Water type mold temperature control machine is suitable for precision plastic injection molding mold temperature control, extrusion molding temperature control, roller heating temperature control, foam production line temperature control, etc. Oil type mold temperature machine is applicable to the thermal process of chemical reactions, rubber and plastic mold temperature control, building materials, printing, paper roller temperature control, food processing, pharmaceuticals, packaging, and other fields of heating and insulation.
Dongguan mold temperature machines are divided into two types: water type mold temperature machines and oil type mold temperature machines. The Daheda small and medium-sized Dongguan mold temperature machine series is designed to provide accurate temperature control for molds, extruder screws, material barrels, caliber measuring devices, high-pressure containers, etc. At the same time, Daheda Dongguan mold temperature machine can be used in a wide range of occasions requiring accurate and real-time temperature control. Accurate temperature control ensures strict temperature control during production, as well as high-quality molds and perfect surfaces. Daheda Dongguan mold warming machine has energy-saving characteristics and is suitable for a wide range of temperatures. DHTW series and DHTO series are equipped with high-temperature resistant pumps to eliminate failures caused by pump seals, and can be equipped with replacement pump seals. The water tank is made of stainless steel to avoid corrosion; In addition, it is equipped with low power density heating components and large area heat exchangers to achieve maximum cooling power. Dahota's mold temperature machine is an instrument used to control the temperature of the mold, the temperature of the screw of the extruder, the temperature of the barrel, and the temperature of the extrusion die head. They can be widely used in instruments that require accurate and continuous temperatures. Accurate temperature control can ensure strict processing technology and produce high-quality products with high dimensional accuracy. Daheda's mold warmer has an energy saving design and can provide a wide temperature range.
The "W" model uses water as a heat conversion medium, with a maximum temperature of 120 ℃. High temperature H models use pressurized water, with a maximum temperature of 140-180 ℃. The "O" model uses oil with a maximum oil temperature of 200 ℃, and the thermal capacity of the standard unit ranges from 6 to 18 kW. The high temperature H model uses a tandem pump or magnetic pump, with a maximum temperature of 300-350 ℃
DHTO series oil type mold heater
The advantages of an oil type mold temperature machine are that it has a large temperature control range and good thermal certainty, but it requires a medium cost, has oil contamination, and has a lower heat transfer efficiency than a water type mold temperature machine. Our newly developed model uses an imported plate type heat exchanger, which has the advantages of compact structure, fast temperature rise and fall speed, and precise temperature control. The temperature control of our oil type mold heater can reach 350 ℃.

Dongguan mold warming machine Purpose: Suitable for auxiliary production of engineering plastic materials and plastic products. For example, nylon, PC, acrylic beer products, etc. The mold temperature machine is preset to reach the temperature required for the injection mold, and one-time molding is a high-quality product, reducing the amount of mold testing materials. Dongguan mold warming machine is widely used in the plastic industry, and its main functions are: 1. improving the molding efficiency of products; 2. Reduce the generation of defective products; 3. Improve the appearance of the product and suppress product defects; Accelerate production progress, reduce energy consumption, and save energy.
A. Improve molding efficiency:
Before molding, automatically control the mold temperature to quickly reach the required temperature and always maintain a constant temperature, reducing the labor required for mold preheating.
2. Sustainable operation without the concern of excessive mold temperature, and downtime on the way does not require waiting for the mold to warm up due to reduced mold temperature, thereby improving production efficiency.
B. Improve product quality:
"Plastics have the physical characteristics of heat expansion and cold shrinkage, so if the mold temperature is unstable or improperly controlled, it can cause water marks, shrinkage, distortion, deformation, and poor surface gloss in the mold. Using a Hailing mold thermostat can solve these problems.".
2. It can promote the mold to maintain an appropriate temperature, significantly reduce the number of molds and reduce the defective rate of molded products, and ensure product quality.
C. Structural characteristics:
1. Water or oil can be selected as the heat transfer medium as needed.
Select a temperature controller equipped with PID intelligent automatic calculation, which can accurately display and control the mold temperature difference within ± 1 ℃ of the required temperature.
The two-stage heating structure design can increase or decrease the power according to the required temperature, and with a special heating structure, it can save time and power.
Various thoughtful protective devices, such as automatic warning systems for lack of fuse switches, water or oil shortages, temperature anomalies, and pump overload, can automatically cut off the circuit to ensure safety.
