Pioneer Trading Company has further strengthened its manufacturing capabilities with the purchase of the groundbreaking Graf SLS Single Head CNC Cill Welder from Haffner. The state-of-the-art machine is the first and only single-head CNC welder specifically designed to deliver seamless bay cills with exceptional efficiency and consistently flawless aesthetics.
After researching the market, Pioneer identified the Graf SLS as a genuine step-change in cill fabrication. The machine produces a perfectly seamless weld with fully automated sprue removal, eliminating the need for any post-weld cleaning or touch-ups and significantly improving fabrication efficiency. Its single-operator design further boosts productivity, while automatic measurement and recalibration of profile tolerances ensure consistent accuracy and reduced material waste.
Danny Williams, Managing Director at Pioneer Trading Company, said: “I’ve been in the industry for 36 years and during that time, manufacturing quality across most areas has improved beyond recognition, except when it comes to PVC-U cills. The same traditional methods are still being used today. The Graf SLS is an absolute game-changer. The finish quality is exceptional, it de-skills labour and the efficiency gains are outstanding. There’s nothing like it on the market.”
He continued: “I was impressed by what I’d read about the machine, but it wasn’t until I visited the Haffner Village at FIT Show 2025 and saw the Graf SLS in action that I fully appreciated its capability. After just one weld cycle, I was sold and signed up there and then.”
Danny was equally impressed with the service received from Haffner during the purchasing process. He said: “Bryan Dando and the Haffner team have been exceptional; the whole process from order to installation has been seamless.”
Now fully installed and operational at Pioneer’s Essex fabrication site, the response from customers has been overwhelmingly positive. Danny added: “The feedback has been excellent, and the quality of the cills we are now delivering are superb.”
Bryan Dando, Commercial Director at Haffner, commented: “Pioneer has always been known for its commitment to quality and forward-thinking investment. Danny immediately recognised how the Graf SLS could transform cill production. The SLS delivers outstanding accuracy and efficiency and we are delighted to support Pioneer as they continue to elevate their manufacturing standards.”
Pioneer’s investment in the Graf SLS CNC Cill Welder further reinforces its position as one of the industry’s most innovative and quality-driven fabricators, ensuring every component of its window and door products meets the exceptional standards customers expect.
