For over 70 years, Leister Technologies has been a global leader in manufacturing plastic welding tools and equipment. Many industry professionals are converting to stationary welders like Leister's SEAMTEK W-900 AT or a stationary table-top welder like the HEMTEK ST for hemming, pole pockets, and hems with ropes. Whether you need a light and compact heat gun like TRIAC AT for small finishing jobs, or the UNIPLAN 500 automatic banner welder to weld larger materials, Leister has the right solution for your needs. Decades of experience make us a qualified partner. Our customers benefit from the highest quality, reliability, innovation, and care.
