Medical Plastic Welding Solutions | Ultrasonic Sealing for Clean Assemblies

Intro

Medical plastic assemblies require more than strong joints. Factories need clean seams, minimal particle risk,

cosmetic-safe welds, and stable quality across long production runs. Our ultrasonic welding solutions are 

engineered for medical plastic parts where low thermal impact and repeatable process control are critical—ideal

for EU & US manufacturing environments.

Typical Applications

• Disposable housings & covers (diagnostics, cartridges, pumps)

• Connectors & fluid handling parts (manifolds, caps, ports)

• Filter housings & micro-porous assemblies

• Sensor/monitoring plastic enclosures

• Any medical plastic part requiring clean, cosmetic-safe sealing

Key Challenges

• Cosmetic defects not allowed: whitening, flash, sink marks, deformation

• Tight tolerance sensitivity: micro parts easily shift, causing leaks or weak welds

• Low thermal impact required: avoid heat damage and material stress

• High consistency for volume production: stable quality across shifts and batches

• Optional traceability needs: parameter capture for process control and audits

Solution Highlights

• Low thermal impact ultrasonic welding for clean seams and reduced material stress

• Closed-loop control options (force/depth/energy) to widen the process window on sensitive parts

• Precision horn + fixture design to protect cosmetic surfaces and maintain alignment

• Cleanroom-ready enclosure options (soundproof/containment) for improved shop-floor conditions

• Process parameter traceability (optional): time/energy/amplitude/pressure logging for QA

Recommended Systems

Servo Electro Precision Ultrasonic Welder (20 kHz) for thin-wall and tolerance-sensitive parts

Soundproof enclosure option for improved workplace environment and compliance readiness

Custom automation stations/lines: feeding + poka-yoke positioning + in-line inspection (optional)

Data logging / traceability module (optional)
