Frequently Asked Questions
How should the machine be stored when not in use for an extended period?
Disconnect the power, clean the machine, apply anti-rust oil, cover it with a dust cover, and store it in a dry environment.
How many people are required to operate the machine?
It requires just one operator plus one person to handle the output; for highly automated models, a single person is sufficient.
Can a single machine produce multiple types of profiles?
Standard models are typically designed to produce one specific profile type per machine. However, customizable models—such as those with interchangeable rollers, double-layer machines, or triple-layer machines—can be configured to enable a single machine to serve multiple purposes.
Does the machine require a foundation?
It simply requires a level concrete floor; no complex foundation is necessary.
Does the machine require disassembly for transport?
The core structure remains intact; only the auxiliary components are removed to ensure that precision is maintained.
