1. Ultrasonic Plastic Welding Machine Spares

Precision components for consistent, high-strength bonds.

Our spare parts for plastic welding are compatible with major industry brands and custom setups. We ensure your frequency stays stable and your welds remain strong.

• Ultrasonic Transducers (Converters): High-efficiency piezoelectric converters (15kHz, 20kHz, 30kHz, 35kHz, 40kHz).

• Boosters: Aluminum and Titanium boosters in various ratios (1:1, 1:1.5, 1:2, etc.) to amplify amplitude accurately.

• Ultrasonic Horns (Sonotrodes): Custom and standard horns made from Titanium, Aluminum, or Hardened Steel. Available for spot welding, staking, and insertion.

• Generators/Power Supplies: Digital and analog replacement cards, mainboards, and complete generator units.

• Protection Film: Durable film to prevent marking on sensitive plastic surfaces.

2. Ultrasonic Metal Welding Machine Spares

Heavy-duty parts for battery, automotive, and electronic applications.

Metal welding requires parts that can withstand immense friction and pressure. Our spares are heat-treated and precision-machined to extend tool life.

• Welding Tips & Anvils: High-wear resistance knurled patterns designed for optimal grip on copper and aluminum foils.

• Sonotrodes for Metal: Specialized Titanium and Steel horns designed for battery tab and terminal welding.

• Fixtures & Clamping Jaws: Replacement pneumatic jaws and holding fixtures to ensure zero movement during the weld cycle.

• High-Power Transducers: heavy-duty converters designed to handle the high-stress loads of metal bonding.

3. Ultrasonic Wire Splicer Welding Machine Spares

Ensuring perfect conductivity and splice integrity.

Maintain the quality of your wire harnesses with our precision tooling designed for automotive and aerospace splicing.

• Welding Tips & Anvils: High-wear resistance knurled patterns designed for optimal grip on copper and aluminum wires.

• Sonotrodes for Metal: Specialized Titanium and Steel horns designed for strong welding wire to wire.

• Fixtures & Clamping Jaws: Replacement pneumatic jaws and holding fixtures to ensure zero movement during the weld cycle.

• High-Power Transducers: heavy-duty converters designed to handle the high-stress loads of metal bonding.

• Cooling Systems: Air cooling nozzles and replacement fans to prevent system overheating.

4. Ultrasonic Sewing & Lace Machine Spares

Clean edges and seamless bonding for textiles and non-wovens.

Keep your sewing units creating lint-free, sealed edges for PPE, sportswear, and packaging materials.

• Pattern Rollers (Anvil Wheels): diverse range of engraved rollers for cutting, stitching, and embossing patterns. Custom designs available.

• Radial Horns: Rotary ultrasonic horns designed for continuous bonding without drag.

• Drive Motors: Replacement motors for roller rotation and horn synchronization.

• Carbon Brushes & Slip Rings: Maintenance parts for rotary couplers.

5. Strip Cutting Machine Spares

Sharp, accurate cuts for webbing, velcro, ribbon, and labels.

Whether you are using hot knife or cold knife cutters, our spares ensure accurate lengths and fray-free ends.

• Replacement Blades:

  • Cold Cut: High-speed steel (HSS) blades for clean shearing.

  • Hot Cut: Heated blades capable of sealing synthetic edges while cutting.

• Heating Elements: Replacement cartridge heaters and thermocouples for hot-knife systems.

• Feed Rollers: Rubber and knurled steel rollers to ensure accurate feeding without slippage.

• Sensors: Length sensors and eye-mark sensors for printed label cutting.
