Sabre Plastics Tooling Ltd


Sabre design and produce high-quality ultrasonic plastic welding tooling, horns, fixtures and jigs for all frequencies. We manufacture for all the leading makes of ultrasonic plastic welding apparatus. 

We are the exclusive supplier of Rinco Ultrasonics of Switzerland in the UK. Rinco are a global leader in first-class, high specification ultrasonic welding systems. We have been making tooling for Rinco systems for over 25 years.

At our site at Letchworth, we have a wide selection of Rinco ultrasonic welding equipment that we display in our showroom. We offer an evaluation service where we can run assessment application trials on your materials or components without obligation.

Ultrasonic Tooling

We can design and produce ultrasonic tooling at any frequency to suit all types of ultrasonic welding apparatus. We have extensive experience and knowledge of ultrasonic cutting horns in the textile and food processing sectors.

Using innovative and advanced diagnostics and tuning equipment, combined with 3D CNC machines, we can produce the best ultrasonic tooling for you. We have the most comprehensive range of machining to manufacture exceptional and accurate welding horns, fixtures and location jigs.

Tool and Mould Making

Our tool and mould making services include repairs and refurbishment. This all happens in our state of the art tool room using the latest CAD CAM software linked to our CNC machining. We can provide unbeatable lead times on fully hardened tooling and prototype tooling.

We have heavily invested in new CAD linked to our CNC machines. It has enlarged our client base and has dramatically extended work load and reduced lead times. We have also gained vast experience with unscrewing tolling and have fitted for all the leading manufacturers.

We offer an 'inserts only' service where possible and this means we can use tool and mould making processes to manufacture tooling at a severely reduced production time and produce cost-effective tools. We also manufacture inserts and integrate them into one of our universal tooling systems.

Sub-Contract Machining

We supply all areas of sub-contract machining that includes wire erosion, 3D CNC milling including true 5 axis, EDM hole drilling, surface grinding, and cylindrical grinding.

We also undertake sub-contracting machining like CNC turning and spark erosion full 4 axis that enables threads and helical forms.

Ultrasonic Plastic Welding

We can supply  Rinco Ultrasonics ultrasonic welding and cutting equipment, Rinco have been enhancing and developing Ultrasonic welding and cutting systems for over  30 years. Supplying equipment into Plastics, Textile and food processing industries.

Using Rinco high-performance ultrasonic welding machines also enables us to supply sub contract plastic welded assemblies.

Injection Moulding

We have vast experiences in the realm of injection moulding and our machines are processor controlled and vary in clamp size from 7 to 380 tonnes. We have a capacity to mould components weighing from the smallest gram up to 1,500 grams.

Our flexible service has meant we have had to continually grow and invest in the state of the art plastic moulding and injection moulding technology to bring you superior performance and results. We can mould small batches of 50 off or fulfil full production requirements.

We have specialised in technical moulding and have the skills and expertise to process thermoplastic materials, including high temperature injection polymers such as PEEK, PSU and PPS.

Our assembly areas are clean and post moulding processes include general assembly, ultrasonic plastic welding, vacuum testing, printing, labelling, packaging and force testing.
