Precision engineering. Intelligent automation.
Plastic welding equipment, automation lines and special purpose machines that raise productivity, hold quality and lower running cost.
Plastic welding
The right process for your part.
We choose the process from your material, part shape, strength target and volume. All tooling is designed and made in-house.

Vibration welding
Friction from lateral vibration under pressure melts the joint faces.
- Linear 120 / 240 Hz
- Amplitude 0.7–1.8 mm
- Weld pressure 0.5–10 MPa
- Clamp force 1–50 kN
Used for
Intake manifolds · Fluid tanks · HVAC ducts · EV battery enclosures

Automation
Lines that assemble, test and inspect.
Systems designed for your product and integrated across assembly, inspection and material handling.
- Assembly automation lines
- Fully integrated lines that combine several operations, built on Siemens or Mitsubishi PLCs with servo drives and HMIs.
- Leak testing and inspection
- Leak testing combined with vision, laser marking and barcode, QR or RFID traceability.
- Vision inspection
- 2D and 3D vision from Cognex and Keyence for inspection, barcode reading and assembly guidance, with PLC pass or fail decisions.
- Conveyors and material handling
- Rotary systems, linear transfer lines and conveyors, with robot cells from YASKAWA, ABB, FANUC and KUKA.

Special purpose machines
Built around your part, proven before it ships.
Every machine is custom-built, validated with Cp/Cpk studies and run-at-rate testing, and accepted by you at our factory before delivery.
- Custom machine design
- A machine built around your part and process, from RFQ and concept through detail engineering, manufacturing, factory acceptance test (FAT) and on-site acceptance test (SAT).
- Multi-station systems
- Rotary and linear transfer systems that combine welding, assembly, leak testing, vision and marking in one machine.
- Servo-driven mechanisms
- Servo motors, ball screws and linear actuators, with SMC and Festo pneumatics.
- PLC and HMI programming
- Siemens S7-1200 / 1500, Mitsubishi and Delta PLCs with 7 to 15 inch touchscreens.
- Safety-compliant designs
- Category 3 and 4 safety controls designed to EN ISO 13849 and ISO 12100, with CE and UKCA marking.
Industries we serve





How a project runs
- 01
Requirement
You share the part, volume and quality targets, with drawings if you have them.
- 02
Concept
We choose the process and propose a layout, cycle time and quotation.
- 03
Detail engineering
Mechanical, electrical and controls design, and the tooling.
- 04
Build and FAT
Manufacture and a factory acceptance test with you before dispatch.
- 05
Commissioning
Installation, on-site acceptance test, training and handover.
- 06
Support
Spares, service and remote diagnostics for the life of the machine.
FAQ
Common questions.
Which welding process is right for my part?+
It depends on the material, part shape, strength needed and volume. Large irregular parts suit vibration or hot plate welding, small precise parts suit ultrasonic, and round parts suit spin welding. Send us a drawing and we will recommend one.
How long does a custom machine take?+
Typically 12 to 20 weeks from design freeze to commissioning, depending on complexity.
Do you test the machine before delivery?+
Yes. Every special purpose machine goes through a factory acceptance test, followed by an on-site acceptance test at your plant.
Which controls and robots do you use?+
Siemens, Mitsubishi and Delta PLCs; Cognex and Keyence vision; and robot cells from YASKAWA, ABB, FANUC and KUKA.
Are your machines safety compliant?+
Yes. They are designed to EN ISO 13849 and ISO 12100 with Category 3 or 4 safety controls, and can carry CE and UKCA marking.
