The key role of mold temperature controller and water chiller in bulletproof plate production
In modern industrial production, precision temperature control equipment plays a decisive role in product quality and production efficiency. Especially in the production process of ballistic plates, mold temperature machine and water chiller are key equipment to ensure stable molding of molds. In addition, oil heating machine and oil heater also play an important role in some high-temperature processes.
This article will introduce the working principles of these temperature control equipment in detail, and analyze how they optimize the production process of ballistic plate molds to ensure high strength, high precision and consistency of products.
Definition of mold temperature machine
Mold temperature machine, full name mold temperature machine, is a high-precision industrial equipment used to adjust the temperature of the mold. It keeps the mold at the optimal working temperature by heating or cooling the medium (water or thermal oil), thereby improving product quality and production efficiency.
Working principle of mold temperature machine
Mold temperature machine usually consists of heating system, cooling system, circulation pump, temperature sensor and control system. Its working process is as follows:
- Heating stage: The electric heating tube or burner heats the thermal medium (water or oil) and transports it to the mold flow channel through the circulation pump.
- Temperature control: The temperature sensor monitors the mold temperature in real time and adjusts the heating or cooling power through the PID algorithm to ensure temperature stability.
- Cooling stage (optional): Some mold temperature controllers have a fast cooling function, which can reduce the mold temperature and shorten the cycle time after production is completed.
The role of mold temperature machine in bulletproof plate mould production
Bulletproof plates are usually made of ultra-high molecular weight polyethylene (UHMWPE), carbon fiber or ceramic composite materials, which are extremely sensitive to temperature during the bulletproof plate mold molding process:
- UHMWPE bulletproof plate: It needs to be hot-pressed at a temperature of 120-160°C. The mold temperature controller ensures that the mold is evenly heated to avoid the material from losing strength due to uneven temperature.
- Ceramic composite bulletproof plate: During high-temperature sintering, the mold temperature controller (especially the oil heating model) can provide a stable heat source of 200-300°C to ensure that the material is fully cured.
If the mold temperature is unstable, it may cause:
✔ Uneven material shrinkage, affecting the impact resistance of the bulletproof plate
✔ Cracks or bubbles appear on the surface of the product, reducing the protection level
✔ Extended production cycle and increased costs
Therefore, a high-precision mold temperature machine is one of the core equipment for high-quality production of bulletproof plates molds.
What is a Water Chiller?
Definition of water chiller
A water chiller is a refrigeration device used to quickly reduce the temperature of molds or equipment. It is widely used in injection molding, die casting, chemical industry and other industries. In the production of bulletproof plates, water chillers are mainly used to cool molds, hydraulic systems or production equipment to ensure process stability.
Working principle of chiller
A chiller performs heat exchange through a refrigerant circulation system. Its core components include:
- Compressor: Provides refrigeration power
- Condenser: Dissipates heat to change the refrigerant from gas to liquid
- Evaporator: Absorbs heat from the mold to cool the cooling water
- Circulating water pump: Transports chilled water to the mold
The role of water chillers in bulletproof plate production
The production of bulletproof plates usually involves high-pressure molding or rapid cooling processes. The roles of water chillers include:
- Shortening cooling time: UHMWPE bulletproof plates need to be quickly cooled and shaped after hot pressing. Water chillers can significantly shorten the production cycle.
- Increasing product density: Slow cooling may lead to uneven crystallinity of the material, while water chillers can ensure rapid and uniform cooling and improve the anti-ballistic performance of bulletproof plates.
- Protecting hydraulic systems: Bulletproof plate forming machines usually use high-pressure hydraulic systems. Water chillers can prevent oil temperatures from being too high and reduce equipment losses.
Application of Oil Heating Machine and Oil Heater
Characteristics of oil heaters
Oil heaters use high-temperature heat transfer oil as the heat transfer medium, which is suitable for high-temperature environments of 200°C~350°C. They are more stable than water-type mold temperature controllers and are particularly suitable for:
- High-temperature sintering of ceramic bulletproof plates
- Hot-pressing curing of composite materials
Advantages of oil heaters in bulletproof plate production
- High-temperature stability: The oil temperature can be precisely controlled at ±1°C to avoid overheating and degradation of the material.
- Safe and reliable: The heat transfer oil is not easy to vaporize, which is safer than steam heating.
- Energy-saving and efficient: The closed circulation system reduces heat loss and reduces production costs.
How do mold temperature controllers + chillers optimize bulletproof plate production?
Complete temperature control solution
In bulletproof plate production, the mold temperature controller is responsible for heating and the chiller is responsible for cooling. The two work together to ensure:
✅ Faster production cycle (reduced cooling waiting time)
✅ Higher product consistency (avoiding quality differences caused by temperature fluctuations)
✅ Longer mold life (reducing mold damage caused by thermal stress)
Actual production case
After a Ukrainian bulletproof plate manufacturer adopted a mold temperature controller (oil heating type) + chiller combination:
- Production cycle shortened by 30%
- Product qualification rate increased from 85% to 98%
- Mold service life extended by 50%
In the production of bulletproof panels, mold temperature controllers, water chillers, oil heaters and oil heaters are key equipment to ensure high quality and high efficiency. They optimize the material molding process through precise temperature control technology, so that bulletproof plates have higher protection performance and consistency.
