Roll Forming Lines | Rotary & Stretch Bending Machinery

Roll Forming Machines | Automotive Door Frame & Chassis Components

Cassette-type roll forming equipment and stretch bending equipment can be used for the production of door frame rails, automotive window tracks, bumpers, and chassis components. Railway cart rails, ship rails and plane components are other transportation applications for roll forming equipment.


High tensile strength steel structural components production equipment. Simulation of flower drawing is performed during the forming equipment design stage for the verification of the metal forming process reliability.


Complete roll forming line stations include – uncoiler/feeder, roll forming, bendingwelding, cutting, and punching.


Client list includes Hyundai, GM, ToyotaHonda, and Nissan; automotive Tier 1 & 2 suppliers Aisin, SNOP, and Dongwon Metal.

Roll Forming Equipment Process

One-Cassette Roll Forming System | Advantages

  • Quicker cassette change time: one cassette system requires 10-15 minutes for a cassette change, while general cassette systems take around 2 hours;
  • No need for experienced labor: operators can immediately start a machine after changing the cassette by connecting the coil to the welder, an experienced operator for a machine line will not be required;
  • No need for overhead cranes: cassette change process can be automated, thus factories do not need to use overhead cranes to change a cassette;
  • High precision;
  • Minimum scrap;
  • High production speed.

On average, LPR’s roll forming machines have 30 stands per cassette. The cassette changing process is fully automated, allowing a cassette to be changed in less than 30 minutes— minimizing tooling exchange time and the downtime of the entire production line.

Roll Forming Machines | Custom Engineered Roll Formers

Delivering state of the art cassette-type roll forming equipment for high precision automotive applications.

Our one-type-cassette forming machines feature a one cassette system, which has 7 cassettes integrated as one, enabling an operator to remove any remaining materials (coils) by cutting them from an uncoiler while leaving any coil materials inside the roller. To start production of a new end product, an operator needs to set up a one-cassette system by connecting a cut-off coil from an uncoiler to the shear-and-welder.

Roll forming equipment for mass production of automotive parts, with an increased production speed of 15~185 m/min allows for a decrease in production time and an increase in capacity.

LPR Global analyses sectional shapes and materials used to guarantee the design accuracy of parts. Specific focus has been made on ultra high tensile materials commonly used to reduce the weight of automobile parts, such as bumper beams, seat rails, cross members, and side sills.
