Review of Popular Thermal Insulation for Plastic Injection Molding Machines: Which One to Choose?

Plastic injection molding machines are high-energy-consuming machines that emit a lot of heat, leading to unnecessary electricity costs. Installing thermal insulation is one of the effective ways to save energy and improve machine efficiency. However, the key issue is which type of insulation to choose.

In this article, we will delve into popular thermal insulation options used with plastic injection molding machines, along with a review of the pros and cons of each type to help you decide on the most suitable product for your factory.

Types of Thermal Insulation Commonly Used with Plastic Injection Molding Machines

Currently, the insulation used in plastic injection molding machines can be divided into three main types:

1. Ceramic Fiber Blanket

   • Made from ceramic fibers, it can withstand high temperatures.

   • Lightweight and flexible, it can be cut to fit the machinery.

   • Has excellent insulation properties, reducing energy loss by up to 30-50%.

2. Silica Aerogel Insulation

   • Has an extremely low thermal conductivity, effectively reducing temperatures.

   • Resistant to high temperatures but is more expensive than other types of insulation.

   • Works well in areas that require thin and highly efficient insulation.

3. Fiberglass Insulation with Aluminum Foil

   • Durable against heat and moisture.

   • Cheaper than ceramic insulation but provides moderate heat protection.

   • Suitable for factories looking to reduce costs while still minimizing energy loss.

Review: HOTFLEX Ceramic Fiber Insulation Model HT-1200

If you are looking for durable thermal insulation that offers good value for investment, the HOTFLEX HT-1200 is an interesting option.

Key Features:

• Can withstand temperatures up to 1200°C – suitable for high-temperature plastic injection molding machines.

• Reduces external machine temperatures by up to 50% – helps keep the factory cooler and reduces air conditioning load.

• Saves 30-50% on energy costs – noticeable reduction in electricity bills within 6-12 months.

• Easy to install and lightweight – can be cut to fit the machinery without hassle.

Pros:

• Long-lasting and does not degrade easily.

• Effectively reduces energy costs.

• Safe for users and does not burn easily.

Cons:

• Higher price than fiberglass insulation, but pays off quickly.

• Requires professional installation for accuracy.

Which Thermal Insulation to Choose?

If your factory needs insulation that offers high durability and the best energy savings, choose ceramic fiber insulation like HOTFLEX HT-1200.

If you need thin insulation that provides the best heat protection in limited spaces, opt for silica aerogel, but consider the higher cost.

If you want to save on budget while still reducing machine temperatures, choose fiberglass insulation with aluminum foil.
