01
Holding profile
Holds components in a defined position: the basis of many fixtures and guides.
Mechanical engineering
High quality standards and reliable function are baseline requirements in mechanical engineering. Heller Kunststoffe manufactures six documented profile families: sealing profiles for control systems, plug-in profiles for positioning separators in control cabinets, plus holding, rail, floor and cover profiles for housings and structures.
Six profile families in use
All six come from real customer projects. The cards stack as you scroll to keep the overview.
02
Rail profile
Structural profile for frames and rails, extruded rigid from hard compounds.
03
Floor profile
Finishes machine floors cleanly and protects edges in rough daily operation.
04
Sealing profile
Seals control and housing systems against dust and splashes, dual-hardness on request.
05
Plug-in profile
Positions separators in the control cabinet: the groove machined exactly to your sheet thickness.
06
Cover profile
Covers edges, grooves and rails: protection against damage plus a clean finish.
Tolerances are a matter of trust
Mechanical engineers think in tenths. Our in-house toolmaking with CNC wire EDM and sampling before series production secure the dimensions you design with.
How your tool is madeFAQ: Mechanical engineering profiles
Which plastic profiles does Heller manufacture for mechanical engineering?
Six documented families: holding, rail, floor, sealing, plug-in and cover profiles, used among others in control system and cabinet construction.
What are plug-in profiles used for in control cabinets?
Plug-in profiles hold and position separator elements in the cabinet. We machine the groove geometry to match your separator and sheet thickness.
Are antistatic or flame-retardant versions possible?
Yes. For sensitive environments we process antistatic or UL 94 V-0 listed materials on request. Details in manufacturing.
Does a custom profile pay off for small machine series?
Often yes: we also manufacture in very small quantities. What the tool costs and what drives it is explained in our article on tooling costs.
Designed? Then we extrude it.
