Trelleborg supplies sealing system to Guangzhou Tech-Long

Trelleborg Sealing Solutions, part of the Trelleborg Group based in Sweden, has supplied a sealing system applying specially developed

Turcon PTFE based compound to Guangzhou Tech-Long Packing Machinery Co Ltd for dispensers located in the center of blow molding machines. Turcon Roto Glyd Ring with a unique pressure relieving function was also included in the sealing solution, according to the company’s press release on August 2.

The sealing system within the dispenser needed to operate in 1-4MPa (145-580psi) dry air pressure at rotational speeds of 150mm/s (6″/s) non-stop for 16-20 hours per day.

According to Trelleborg Sealing Solutions, dry air is a difficult medium to seal. To successfully do this the seal must initially demonstrate a very smooth and tight dynamic sealing surface after a short run in. It must then have outstanding wear resistance in poorly lubricated conditions.

“We are continually trying to offer our customers machines that maximize production capability while minimizing downtime for maintenance,” said Zou DaQun, Technical Director of Tech-Long, the largest manufacturer of PET (polyethylene terephthalate) bottle blow molding machines in China. “Trelleborg Sealing Solutions is a very good partner to Tech- Long. They do not just sell products but more importantly provide professional technical services and solutions. That is what Tech-Long is really interested in and why we have been in cooperation with Trelleborg for 10 years continuously.”

As revealed, sealing configurations from Trelleborg Sealing Solutions are now successfully operating in Tech-Long PET bottle blow molding machines globally. Tech-Long and Trelleborg Sealing Solutions continue to work together on new developments.
