Some of the key differentiating features you’ll find in Corma's corrugators.

1. Unified mold block system

Mold blocks from smaller corrugators can be run on larger corrugators thanks to Corma's innovative carrier adaptors. Standards mold blocks are 1", 2", 4" and 8" wide.

2. Supercooling

This revolutionary cooling method cools both the pipe and mold blocks, resulting in higher output rates of 25% to 100% and quick mold block changeovers, and requires virtually no maintenance.

3. Mold block quick return system

This patented system increases production speed and provides more efficient and consistent cooling. The system also reduces initial investment costs by as much as 25%, due to the requirement for fewer mold blocks.

4. In-line coupling

This patented system permits in-line coupling systems for double- and triple-wall pipes to be produced during the corrugation process. Key advantages include the elimination of the downstream belling machine, resulting in substantial savings. It also ensures production isn’t slowed down to match the cycle time of the belling equipment.

5. Electric centre height adjustment

This feature allows multiple pipe sizes to be produced on a single corrugator.

6. Mold block cooling

A patented design for the greatest cooling efficiency: air cooling during the return cycle lowers mold block temperatures for greater quality and productivity

7. Upper housing lifting device

This electrically operated device makes it easy to quickly and accurately align the die tooling to the mold blocks, simplifying maintenance and reducing downtime.

8. Adjustable length corrugators

This feature permits lengthening or shortening of the mold track length in one mold block increments, thereby eliminating waste when making a variety of pipe lengths.

9. Controls

All corrugator functions are operated from a central, computerized control station. Emergency shut-offs are located around the machine, and terminals for an interlock feature between the extruder and the corrugator are located in the corrugator panel.

10. Mold block insert

Breakthrough mold block insert technology allows for multiple pipe profiles and stiffness classes to be produced on a single set of mold blocks with just a quick and simple insert change. This decreases the required investment in mold blocks and die tooling, accelerates changeovers, and minimizes product weight while ensuring compliance with the applicable pipe standards.

11. Cooling enclosure

This innovative cooling method further enhances the cooling capacity of the corrugator. The system incorporates an enclosure, temperature control system, high pressure blowers and mold block design to optimize cooling and productivity.
