Roop Ultrasonix Ltd. products

The Ultrasonic hand welder is ideal for small welding, riveting and inserting operations using thermoplastic materials; where the manual assembly is required. The very compact instrument is suitable for small series applications and laboratory. A further application is spot welding and staking of large parts which require a large degree of mobility of the welding equipment. The operation is very simple. Because the operating frequency is 35 kHz, noise emissions are usually no problem. The equipment can therefore be used in any environment.

All Good Things in One Machine. RTUL offers high power/high precision equipment for wire splicing. Precision and reliability are decisive preconditions for electrical connections in automobile wire harnesses. Ultrasonic welding ensures flawless electrical conductivity in the wire splices over years and years.

Ultrasonic cutting and sealing process is mostly used in the field of textiles on circular loom. The principal advantage of the ultrasonic seal and cut method is that the edge of the textile material, while being cut simultaneously, is sealed by the dissipation of ultrasonic energy , thereby preventing the presence of a frayed edge or the unraveling of threads, no discoloration of fabric and very strong, smooth, clean and long lasting edges without over thickness with low energy consumption. The model is mainly used for cutting of woven sacks, HDPE or PP circular woven fabric, etc. Ultrasonic cutting is mostly used in cutting of Synthetic (Polyester, Nylon) fabric cutting, saree cutting, BOPP film sealing. The technology has tremendous advantages over other cutting methods such as cutting without pressure prevents any deformation of the material, high quality of the cut is achieved, no smudging or breaking of individual layers,

Ultrasonic continuous sealers provide a big benefit over conventional stitching methods. The system can perform two manufacturing processes in one flow i.e (Cut & Seal), there is no wearing due to steel sonotrode and prevents the material from fraying. The Ultrasonic Sealing System is designed with a motor, roller, electronic control & working table for sealing of Fabrics, Plastic Films, Laminated paper, Non-Woven Fabrics, Filters, etc. It is a versatile Machine and the location of the horn and anvils enable flexibility and tight turns in sealing, This also provides an unobstructed view of the fabric in the processing area.

Historically, heat sealing has been the technology used on many horizontal forms of packaging machines. Although this has become the established process for many applications, it can have its drawbacks, common issues include leakages attributed to product contamination within the seal area, coarse particles such as sugar or coffee causing puncturing, odours from trapped product, and unsightly burnt edges. Ultrasonic welding is a reliable and economic alternative for typical thermal processes that ensures tight weld seals despite of product contamination. Ultrasonic welding technology is particularly well suited for packaging processes with high production rate requirements and applications with challenging process. The ultrasonic process also offers additional benefits such as cold welding/sealing process, tight sealing of films, repeatable and analyzable weld process which is not possible when using radiant heat process. 

Ultrasonics, i.e. high frequency vibrations, generate agitation in liquid resulting into ‘Cavitation’, which is rapid formation and collapse of minute bubbles in liquid. Implosion of bubbles with high pressure on exposed surface of component dislodges and removes contamination like dirt, dust, oil, grease, chips, wax, lapping paste, carbon etc. Very high degree of cleaning can be achieved in multi-chamber/multi-operation cleaning system with proper orientation of components, filtration of cleaning liquid, rinsing of components and drying with air and/or vacuum.
