The Ultrasonic Plastic Degating Machine is an advanced industrial solution designed to streamline plastic manufacturing processes. Utilizing high-frequency ultrasonic technology, it efficiently and precisely removes excess gates and runners from injection-molded plastic parts. With its innovative design and robust construction, the machine delivers clean, damage-free degating — ensuring high-quality finished products with minimal post-processing.
The system is particularly well-suited for a wide range of thermoplastics, including polystyrene (PS), nylon (PA), ABS, polycarbonate (PC), AS, PMMA, and more.
The ultrasonic degating system serves diverse industries:
Why ultrasonic is ideal for plastic degating
Degating is the process of separating finished parts from the runner and sprue system after injection molding. Once the molded plastic cools and solidifies, each gate must be removed cleanly — and ultrasonic technology makes this step faster, cleaner, and more consistent than manual cutting or mechanical trimming ever could.
MCSONIC ultrasonic degating machines deliver semi-automatic or fully automatic degating with exceptional precision and speed — eliminating stress marks, reducing part rejection rates, and streamlining your entire molding workflow from injection to finished part.
Molded parts leave the press with a runner and gate attached, and every one has to be separated cleanly before the part is packed, assembled or painted. This ultrasonic degating machine does that job with high-frequency vibration rather than a blade: the operator positions the molded part on the work table, the tool separates the gate from the part, and the finished part leaves the station ready for the next step.
It is made for injection molders working with everyday thermoplastics, and it comes from MCSONIC, a builder of ultrasonic plastic welding machines and other industrial welding machines. The machine stands as its own station, so gate removal no longer depends on how steady a hand is with a trimming knife.

This machine is set up for the thermoplastics that fill most molding schedules. Polystyrene and AS appear in rigid, glossy parts such as housings and disposable items, where the gate area has to stay visually clean. Nylon (PA) and ABS are tougher engineering materials used in brackets, clips and appliance parts, while polycarbonate suits clear or tinted components where a whitened gate mark would be obvious. PMMA covers lenses, light guides and display covers in the same way.
Glass-filled and heavily reinforced grades behave differently at the gate, so send us the material grade, part drawing and gate layout. As one of the ultrasonic plastic welding machine manufacturers supplying plastic processors, we will confirm whether ultrasonic separation is the right method for your part before you order.
Unsure which ultrasonic system fits your workpiece or production line? MCSONIC's engineering team helps you select the right machine, horn or blade configuration before you order, backed by over 15 years specializing in ultrasonic cutting and systems widely used in factories worldwide. We support customization of key parameters, integration into existing automation lines, and clear guidance on installation, commissioning and daily operation. Our after-sales engineers help troubleshoot issues remotely or on site, and selected systems support remote diagnostics. Send us your drawings, samples or cycle targets and we will recommend a practical configuration.
Reinforced grades behave differently at the gate, so they are worth checking before you order. Tell us the grade you are running and our engineers will confirm whether ultrasonic separation suits the part, or whether a different set-up is needed for that material.
A trimming knife deforms the plastic as it cuts, which can leave whitening, stress marks and rough edges that have to be cleaned up or rejected. Ultrasonic vibration separates the gate with minimal impact on the molded part — the same principle used in ultrasonic welding equipment, applied to gate removal rather than joining. The result is a neater gate area and fewer parts lost to rework.
Semi-automatic operation suits mixed production, where an operator places each part and controls the cycle. Fully automatic degating is the better fit when a small number of parts run at high volume and you want the handling taken out of the job. Tell us your part mix and expected output and we will recommend the arrangement that suits your line.
The runner and the part come away from the ultrasonic degating machine as separate pieces, so runners can be collected and returned to your regrind stream in the usual way instead of being sorted out of a pile of trimmed parts.
The control interface is designed for production floor use, so operators can set and monitor the cycle after a short introduction. The daily routine is simple: load a part, run the cycle, check the gate. As one of the ultrasonic plastic welding machine manufacturers working with molders every day, we can arrange start-up support while your team gets comfortable with the station.
It can be re-set for different parts, and how much changeover that involves depends on how similar the gate layouts are. Send a list of the parts you want to run and how often you switch between them, and we will advise on how to set the station up for those part families.
