The Pursuit of Innovation and Quality – Corma featured in the Latest Issue of the Beijing Review

As a specialist in corru­gated plastic pipe manu­facturing equipment for over 40 years, family-owned Corma is build­ing on its international reputation.

Last year Corma was presented with the Lead­ership Award of Excel­lence at the 2016 Ontario Export Awards and the company is today recognized as a leading producer of machinery and die tooling equipment for the corrugated plastic pipe manufacturing industry.

“We were a very small start-up when we began in 1973,” recalls Manfred Lupke, Founder, Presi­dent, Chief Executive Of­ficer and an inductee into the Plastics Academy Hall of Fame.

“Our company consisted of myself – a mechanical engineer, a colleague of mine and my wife who was responsible for the entire office.”

Today, the company employs over 250 people and has delivered over 1,300 machines to more than 100 countries. With headquarters in Concord, Ontario, Canada, Corma has regional sales and services offices in Europe, Asia and Latin America and a manufacturing facility in China.

“Over 20 years ago, we were invited to join one of the first delegations to China to explore investment and manufacturing opportunities,” says Lupke. “This initial introduction to the Chinese market and later experiences prompted us to invest in China around 10 years ago. Corma Shanghai is an important link in our supply chain.”

Corma’s machinery features the latest cutting-edge technology designed to help companies produce high-quality pipes with optimal efficiency, cost-effectiveness and space requirements while minimizing downtime.

“Plastic corrugated pipes and tubing produced on our machines range from 1 mm to 3,000 mm in diameter and we are able to customize production systems and auxiliary equipment to meet the specific requirements of our clients,” says Lupke.

“Our machines can be engineered to work with a variety of materials to ensure requisite pipe stiffness, adherence to worldwide standards and material cost savings.”

In recognition of the company’s technical innovations, Corma was awarded the Vaughan Chamber of Commerce Business Achievement Award for Innovation in Production or Technological Advancement last year.

By delivering a patented range of pipe manufacturing machinery, dies and die tooling equipment, downstream equipment for manufacturing PVC pipes and polyethylene and polypropylene plastic tubing, Corma is winning new customers.

“We are driven to innovate, deliver quality products and be a reliable partner for our existing and future customers,” says Lupke. “We have over 1,000 international patents and many more in various stages, and from a manufacturing perspective, China remains a very important part of our value chain. We are proud to have been one of the earlier Canadian companies to visit the country and we are more than happy with the close relationship we enjoy with our friends in China.”

Corma July 2014 Newsletter – Corrugator Supercooling

Corma Technology Showcase:

Method and Apparatus of Cooling Product within a Mold

Corma Corrugator Mold Block Supercooling
Corma’s Supercooling technology channels cool air into the mold blocks to maintain optimal temperature.

In 1973, Corma introduced the first air-cooled corrugator machine to the world.  Since then, every single one of our corrugators has been air-cooled, making it a distinct signature of our product line.  At the time, we were ridiculed by our competitors who were all using water-cooling.  However, it would appear that their technology has reached its limits as we are noticing more companies developing so-called “new” air cooling systems that we have already been refining for the past 41 years.  It has evolved to include our patented Supercooling™ system and patented Insulated Cooling Enclosure, combining to make Corma air-cooled corrugators some of the most efficient and effective machines currently available.

When the plastic sets up and cools down it shrinks and pulls away from the mold, creating a gap between the pipe and the mold that effectively acts as an insulator.  Picture a cold glass of water with condensation that runs along the sides – if you take both hands and hold the glass, your hands will feel very cold.  However, if you remove your hands from the glass and stay close to it without touching, you will feel almost nothing cooling your hands.  The small air gap insulates the cold glass from your hands, similar to how a double pane window insulates the outside temperature from the inside the house.  This principle is also applicable to mold blocks and plastic.

The concept of our Supercooling™ technology (patented in 1998) is to channel cold air into the gap between the pipe and mold to maximize cooling efficiency.  Cold air travels through the vacuum forming slits on one end of our mold block into the gap, then exiting out through the slits on the other end.  This method efficiently cools both the pipe as well as the mold blocks.

Corma Corrugator Enclosure
Corma’s corrugator enclosure maintains optimal operating temperature of the corrugator system as well as prevents condensation from building.

In addition, our Insulated Cooling Enclosure is a climate controlled system that maintains optimal operating temperature throughout the year.  This means energy requirements are lower than conventional cooling systems that continuously blow air because our enclosure only requires energy to cool the corrugator when needed, which also prevents overcooling issues as well.

The combination of our Supercooling™ technology and insulated cooling enclosure increases productivity from 25% up to 50% with less energy usage and consistently produces high quality pipes that have minimal inherent stress.  As an innovation leader, we are already working on a new patent for mold block technology with a cutting-edge air-cooling system to further enhance the capabilities of our clients’ businesses.  Please stay tuned for more information on how Corma can make a positive impact on your bottom line!
