DC INVERTER CHILLER SOLUTION FOR ENGINEERING PLASTICS IN AUTOMOTIVE AND ELECTRONICS INDUSTRIES
15:32 - 07/10/2025

As Vietnam’s industrial manufacturing accelerates, especially in the automotive and electronics sectors, engineering plastics are increasingly replacing metals thanks to their lightweight, durable, and heat-resistant properties. Along with this trend, the demand for precise and stable cooling systems in molding and forming processes of engineering plastics has become more stringent making large-capacity industrial chillers an essential part of modern factories.

OVERVIEW OF ENGINEERING PLASTICS IN THE AUTOMOTIVE AND ELECTRONICS INDUSTRIES

Engineering plastics are a group of high-performance materials including ABS, PC, PA, PBT, PPS, and POM, developed to meet strict requirements for mechanical strength, thermal resistance, and chemical stability. Compared to conventional plastics, they offer significantly higher rigidity, tensile strength, and impact resistance while remaining lightweight.

Engineering plastics in the automotive and electronics industries - overview

In the automotive industry, engineering plastics are used to manufacture components such as headlamp housings, dashboards, interior panels, engine covers, sensors, and electronic mounting frames. Replacing metal with plastic helps reduce vehicle weight, improve fuel efficiency, and enhance design flexibility.

In the electronics industry, engineering plastics are applied in the production of device casings, PCB holders, insulating components, switches, and sockets, ensuring high dimensional stability and durability even under elevated operating temperatures.

A common requirement across both sectors is precise temperature control during the injection molding process. Even small temperature fluctuations can affect surface gloss, dimensional accuracy, and product lifespan.

COOLING CHALLENGES IN ENGINEERING PLASTIC MANUFACTURING

Unlike general-purpose plastics, engineering plastics require higher mold temperatures (typically 80–120°C) and longer molding cycles creating significant challenges for cooling systems.

If the cooling system is unstable, manufacturers may face:

  • Warping, shrinkage, or surface cracking of products.
  • Extended cooling times, reducing production efficiency.
  • High energy consumption due to continuous high-load operation.

Engineering plastics in the automotive and electronics industries - cooling challenges

Factories producing automotive and electronic components often operate dozens to hundreds of injection molding machines. Therefore, investing in large-capacity chillers for process water cooling is essential. However, traditional on/off chillers reveal clear limitations: high energy usage, unstable temperature control, and poor reliability during continuous multi-shift operations.

THE MODERN SOLUTION: DC INVERTER CHILLERS FOR ENGINEERING PLASTICS

The introduction of DC Inverter chiller technology marks a major breakthrough in industrial cooling. Instead of the conventional on/off mechanism, DC Inverter chillers use variable-speed DC compressors that automatically adjust frequency to maintain water temperature stability within ±0.5°C.

For engineering plastic factories, this brings tangible benefits:

  • Stable water temperature ensures dimensional accuracy crucial for thin-walled, precision components.
  • Improved surface quality, minimizing defects like warping or cracking caused by uneven shrinkage.
  • Energy savings of 30–40% compared to traditional chillers, especially for factories running multiple shifts.

Thanks to these advantages, more and more manufacturers in Vietnam’s automotive and electronics engineering plastics sector are adopting large-capacity DC Inverter chillers to optimize costs and maintain consistent product quality.
