In 1974 Corma founder and President, Manfred Lupke, designed, produced and delivered the M600: the world’s first corrugator with vertical construction and independent mold block carriers. This vertical construction is the foundation of our machines while continuing to embrace technological changes evolving and improving our design. This unique construction and its benefits are in every corrugator we have delivered around the world to our customers.
Wear and tear is low on Corma corrugators due to our vertical design. A small gap between the top and bottom mold blocks is left when they are closed, allowing for expansion and free movement. Specifically designed column spacers are used for each mold block size to create the perfect mold block closing position and pressure. Our drive system applies force at four points of contact to the mold block carriers pushing them around evenly, preventing them from tilting or jamming.
The vertical design gives access to and around the machine allowing for easy maintenance and setup. Having a clear and uninterrupted view of the mold blocks against the tooling decreases the time for size change setups and prevents damage from incorrect alignment. All our corrugators have lateral, as well as center height adjustment, which allows for accurate centralization to occur. This allows for control of concentricity between the mold block and die tooling, and during manufacturing.
The vertical construction enables Corma corrugators to produce a wide range of pipe sizes and specialized profiles. Together with our Unified Mold Block System and Mold Block Adaptor Shoes we can offer our customers a highly versatile production capability, allowing mold blocks to be shared across machine sizes, minimizing capital investment of mold blocks, while still preparing for future expansion. The vertical design allows for our machines to have a much smaller footprint. Compared to a horizontal machine that can manufacture pipe in similar ranges, the Corma design footprint is 50% less. Utilizing the wasted space above and below allows for efficient use of the factory floor space.
The vertical design enables a single person to remove and install the mold blocks as pairs on the operation side of the machine, without the need for tools or fixings.
The vertical design ensures that the top and bottom housings and mold block chains are perfectly balanced. This reduces the stress and fatigue on the machine allowing for smooth rotation regardless of mold block size.
The vertical design allows for all services to be accessible from the sides, negating the need for them to rotate with the mold blocks. The vacuum is provided to the mold blocks directly from the top and bottom housings, giving the best vacuum levels for processing and product quality.
