Foamed wire line
We offer a wide range of products, from insulated wires, LAN cables, and telecommunications cables made of FEP/PFA/PP/PE to large-scale coaxial cable lines.
We have a particular strength in gas foaming, and we are very proficient in it.
Furthermore, ROSENDAHL handles everything from molding and welding copper tapes, such as RF cables, to corrugating them.
Automotive power lines
Its distinguishing features are its ultra-high-speed production line and the high quality of its products.
Furthermore, the ROCOMAT quick color change system in this line has received significant acclaim worldwide.
Low-voltage power cable
We have received particularly positive feedback for our silane bridges.
We support a variety of applications, including liquid silanes and dry silanes.

High-voltage power cable metal sheath line
We developed this product by applying ROSENDAHL's metal forming, welding, and corrugating technologies used in RF cables to high-voltage power cable applications.
Equipment Introduction
ROEX extruder
ROEX series
The ROEX series of extruders from ROSENDAHL features unique design innovations in each part of the extruder, resulting in a compact size, high discharge rate, and extremely linear discharge volume.
Furthermore, the resin temperature does not rise easily even at high rotational speeds.
The ROEX series offers a lineup ranging from ROEX30 to ROEX150, providing the optimal extruder for each material, discharge rate, and process.

Metal tape molding and welding equipment
Metal tape molding machine
Molding image
ROSENDAHL offers three basic types of forming machines for metal tapes, including static, hybrid, and roll types, depending on the tape specification.
Based on our many years of experience and proprietary software, we design and propose the optimal molding method and tool placement.
A key feature of ROSENDAHL's molding equipment is the consistently high precision of the butt joint position during molding.
In addition to butt joint molding equipment, we also handle overlap-type molding machines.

Metal tape welding technology
Welding drawing
ROSENDAHL offers welding technology for metal butt joints.
Due to the specifications of the metal tape, the number of torches at the welding station is limited to 1 to 3.
This is achieved by combining the welding machine with ROSENDAHL's proprietary program.
In addition, it contributes to improving welding quality.
Furthermore, by using a two-head welding station, it is possible to weld without stopping the line.

SZ twisting machine
Product Examples
It is used in fan-shaped power cables, eliminating the need for large stranded wires and allowing for in-line insulation.
The device will be simplified and maintenance will be easier.
Furthermore, no special foundation is required.
ROCOMAT Quick Color Change System
Layout example
The ROSENDAHL color change system features a mechanism that changes colors within the crosshead.
This makes it possible to drastically reduce the time required for color changes and minimize waste.
