High-Pressure Forming Machine Troubleshooting: Why Heating Tubes Fail Early
Why heater tubes on a high-pressure forming machine fail early: vibration of the heater plate. Set the cushioning of the heater-plate cylinder correctly and tighten loose parts monthly.
A high-pressure forming machine consists mainly of a hydraulic press and a heating unit made of carbon-fiber heating tubes. The tubes themselves last long, yet on some machines they fail within a week while on others they last six months. The original article traces the difference to heater-plate vibration.
Cause
If the cushioning stroke of the cylinder that moves the heater plate is not set correctly, the cylinder shakes, the heater plate vibrates and the tubes are damaged.
Fix
- Adjust the cushioning of the heater-plate cylinder.
- Service the machine monthly and tighten any loose parts.
The machine is hydraulically driven for smooth, even force. Current model: AS201F-G high-pressure gas forming machine. Heater types compared: IMD/IML thermoforming machines: process and applications.
