Cylindrical Heating Elements

Flat heating elements, adapted to the heated part, usually cylindrical shape. They are designed in such a way that they can be firmly attached to ensure efficient heat transfer. The carrying elements are made of either mica or ceramic for higher performance. The customer selects the type of the outlet, the shape of the element and the openings for clamping or the mounting brackets for the sensors.

The main areas of application are:

  • Heating of pipes and chambers of injection moulding machines in the plastics industry
  • Heating of the jet nozzles (tips) of injection moulding machines
  • Heating of moulds in the plastics industry
  • Heating of transport pipelines
  • Heating of heating tables
  • Heating of welding bars and press dies

Ceramic

Heating elements are made of ceramic segments with openings through which the heating coils pass. The unit is contracted with a stainless steel cuff and fixed to the heated part. Possibility to deliver a version without a metal casing.

The advantages of these heating elements are their high heat output, higher operating temperatures, and long service life when used correctly.

Example of application: Heating belts for extruders and chambers of injection moulding machines

Derivatives: cylindrical belts with linked openings, heating of large cylindrical elements

Temperature: up to 500 ° C

Operating voltage: 12-400V AC/DC ; 1p ;3p,
Surface load: 8-10W/cm2,
Approximate wall thickness: 12mm
Type of heating: contact outer
Min. mounting diameter: 70 mm
Length: 25 – 500mm

Mica

Heating elements made of mica plates wrapped with a flat heating strip. The unit is enclosed in a stainless steel or nickeled case and clamped with an external clamping sheet metal.
Possibility to deliver a version without a metal casing.

The advantage of these elements is a small design thickness and a significant range of resulting product dimensions.

Example of application: Heating belts for extruders and chambers of injection moulding machines

Derivatives: cylindrical belts with linked openings

Temperature: up to 400 °C

Operating voltage: 12-400V AC/DC ; 1p ;3p,
Surface load: 4-5W/cm2,
Approximate wall thickness: 4mm
Type of heating: contact outer
Min. mounting diameter: 25 mm
Length: 25 – 500mm

Hermetically sealed

It is a special variant of cylindrical heaters. The heating part of mica sections is wrapped with a resistance strip. The unit is encapsulated in a casing made of a closed brass tube with a soldered outlet and is tightened to the heated part with tightening screws.

The advantages of these elements are a small built area and resistance to penetration of foreign material into the body, which is why these elements are directly destined for use on heating of injection jet tips in plastic making machines.

Example of application: heating of injection jet tips in plastic making machines

Temperature: up to 350 °C

Operating voltage: 12-400V AC/DC ; 1p ;3p
Surface load: 7W/cm2,
Approximate wall thickness: 4mm
Type of heating: contact outer
Min. mounting diameter: 25 mm
Length: 22 – 100mm

PRICE VS. ORIGINAL
Custom production allows the production of elements with almost any parameters, both geometrical and electrical; it is, therefore, possible to replace the existing heating element with a non-original replacement. You can request a list of affordable type substitutes. Also, you can send us documentation, a photo, or a physical sample and we'll suggest a solution for you.

SPEED
Time is money - we normally keep delivery terms at a weekly level. If necessary, the term can be shortened (surcharge) or special delivery terms can be agreed. All activities from the offer, through design, calculation and production are minimized with regard to the speed of the entire order.
Default text 3
We produce a wide range of heating elements. Heating elements are divided into heating strips, heating cartridges and other types.

We produce custom-made heating elements according to your requirements.

We are not limited by a predetermined range, therefore, we respond flexibly to your needs and wishes.

We offer technical advice to help you find the optimal solution
