Non-Contact Infrared Welds Reinforced PP Pressure Tanks

APPLICATION CONCEPT  |  PLASTICS PROCESSING

CUSTOM INDUSTRIAL INFRARED HEATING

PUBLIC CASE REFERENCE

Create a clean melt layer
before the tank halves are pressed.

High-power short-wave infrared modules heat the two cylindrical joint faces without contact.

28 bar REFERENCE BURST TEST

Reference data subject to application testing and specification review.

Non-Contact Infrared Welds Reinforced PP Pressure Tanks industry application

The Process Challenge

Hot-plate welding can expose glass fibers and wear non-stick coatings. Frequent plate maintenance can reduce availability and affect the joining surface.

The Infrared Approach

High-power short-wave infrared modules heat the two cylindrical joint faces without contact. After the melt layer forms, the heater withdraws and the halves are pressed together.

1

ALIGN

Fixture tank halves

2

HEAT

Create melt layer

3

RETRACT

Remove heater

4

JOIN

Press and cool

Application Features

  • No contact between heater and reinforced polymer
  • Circumferential zoning can balance the joint temperature
  • Retractable heater integrates with automated presses
  • Process data can support weld traceability
  • Burst testing validates the complete vessel

Typical Configuration

PUBLIC RESULT

Vessel failed before weld at about 28 bar

REFERENCE TIME

About 40 s to melt temperature

EMITTER

High-power short-wave infrared

REFERENCE MODULE

Six 1.6 kW emitters per module

CUSTOM DESIGN

Diameter, contour, travel and zoning

CONFIRM

PP grade, glass content and pressure test

APPLICATION NOTE

Public case-study reference - not a YFR performance claim. Confirm equivalent results through YFR sample testing before publishing as a customer result.
