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.
LPR Global’s roll forming equipment designed for the mass production of automotive parts provides an increased production speed of 15 – 185 m/min, allowing for a decrease in production time and an increase in capacity.
LPR Global analyzes sectional shapes and materials used to guarantee the design accuracy of parts. A specific focus has been placed 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.

Project Experience | Bumper Beam Production Line
LPR has provided production lines for bumper beams used in the automotive industry. Bumper beams are a crucial component of car bumpers, responsible for absorbing energy in the case of a crash and ensuring the safety of passengers. Bumper beams must have shock-absorbing qualities while remaining lightweight for vehicle fuel efficiency and to maintain the vehicle’s centering and stability. For this reason, bumper beams have hollow cross sections, adding complexity to the manufacturing process.
LPR provides bumper beam production lines which include roll forming lines to produce beams with the specified cross-section, followed by stretch bending machines capable of producing the required shape while preserving the cross-section. LPR’s tube bending machines for bumper beam production are suitable for bending aluminum and high-strength steel.
