Heating Bands

Mica heating bands, also known as micanite heating bands, are the standard solution for temperatures up to 350 °C. The heating element is sandwiched between two layers of micanite, and the outer jacket is made of AISI 430 stainless steel. Thanks to their flexible design, they can be installed even in tight spaces. Round versions are called ring heating bands, and foldable variants are available.

Typical applications include plastics processing, hot-runner systems, and packaging equipment. Four models are available.

HKE 50 Standard Model

The classic mica heating band. It is wrapped around the cylinder and secured with a tension clamp or clamps. The right choice for most applications in plastics processing.

Construction: 1. Bottom panel, 2. Insulated sandwich panel with resistance winding, 3. Cover panel, 4. Outer panel

HKE 52 with heat distribution plate

A 1.5 mm-thick copper sheet inserted into the heating tape distributes heat more evenly across the surface. This is useful wherever the heating tape has multiple holes or cutouts and temperature variations would otherwise occur. The copper sheet can be identified by its gold-colored inner side.

Construction: 1 Copper heat distribution plate, 2 Insulation sandwich with resistance winding, 3 Cover plate, 4 Outer plate

HKE 53, internal clamping version

This heating tape is not wrapped around the outside of the cylinder but is secured inside the pipe. The configuration is reversed, with the heating surface facing outward. This allows pipes and hollow structures to be heated from the inside. This design is rarely available on the market.

There are three types of fasteners available. Which one is suitable depends on the installation space and mounting position.

Construction: 1 Cover plate, 2 Insulation sandwich with resistance winding, 3 Inner plate

HKE 54 with additional insulation

This version features a second layer of insulation directly on the heating tape, as indicated by the ribbed outer jacket. It reduces heat loss to the outside without requiring the installation of a separate insulating jacket.

Construction: 1. Base plate, 2. Insulated sandwich panel with resistance winding, 3. Cover plate, 4. Insulation layer, 5. Corrugated outer casing

In special cases, these values may be exceeded. The key factor is whether the power can be physically dissipated and the heat removed. Please contact us; we’ll evaluate your application.

For diameters greater than 400 mm, we recommend dividing the pipe into several heating segments.

Ceramic heating bands are used wherever cylindrical surfaces need to be reliably heated to high temperatures. The ceramic elements store heat and release it evenly, ensuring that the temperature distribution remains stable even during continuous operation.

The robust design reduces heat loss and ensures long-lasting, continuous operation. Upon request, we also manufacture ceramic heating bands in a foldable design and as ring-shaped heating bands for round components.

In special cases, these values may be exceeded. Please contact us, and we will review your application.

For diameters greater than 400 mm, we recommend dividing the pipe into several heating segments.

Insulation jackets keep the heat where it's needed. There are two types.

Separate insulating jacket

It is placed over the heating band or over the entire cylinder and fits both mica and ceramic heating bands. It is custom-made, either for a single heating band or for an entire cylinder assembly.

Insulation layer directly on the heating tape

In this version, the insulation is incorporated as an additional layer within the heating cable itself, as indicated by the ribbed outer jacket. No separate jacket is required, and the heating cable has a more compact design. We carry this model as the HKE 54.

The Benefits of Insulation

Energy consumption for heating is reduced by 20 to 40 percent. The surface temperature of the cylinder drops by 60 to 75 percent, which reduces the risk of injury and the heat load in the facility. The heating elements operate at a more constant temperature and therefore last longer.

Calculation example: An injection molding machine with a clamping force of 12,000 kN and ten ceramic heating bands with a combined power of 100 kW saves approximately 1,440 euros in energy costs per year when equipped with insulating sleeves. The investment typically pays for itself in less than a year.

The electrical connection is selected to suit the installation situation. All junction boxes are made of sheet steel and are rated for 230 V and 400 V. The dimensions in the drawings are given in millimeters.

Three designs are available. Axial runs the cable toward the cylinder axis and takes up the least space. Radial It extends vertically away from the cylinder, which is useful when there is limited space on the side. Tangent It runs along the side of the cylinder.
