Controllers for reducing hot runner problems and downtime
Plastic leak detection
When leaks happens, additional power is required to hold the set point because more heat is transferred to the water-cooled mould plate. The controller also applies more power to compensate for the heat loss and the resulting rise can be detected by the computer, which can trigger an alarm.
Mold-Masters said it has recently released an addition to its M1 range of hot runner temperature controllers. The M1-24 model, for up to 24 x 15A zones, is positioned between two earlier cabinet sizes for 12 or 48 zone capability, offering a very compact and economical modular controller with many advanced features, the supplier explained.
This mid-range controller houses plug-in six-zone 15A control cards with low voltage soft start, current measurement and ground fault detection as standard for heater protection.
A decade of protection
The company said it offers a 10-year warranty for the heater circuits of a complete hot half and controller package. The colour touch screen console clicks into various viewing angles or packs away vertically for protection. The supplier said the software is primarily designed for simplicity of use but with many advanced functions available such as individual or group setting of set points, alarm limits, boost and standby values, wiring diagnostics, temperature and power output graph, automatic follow start up modes, multi language support, password control option, tool store memory and USB file transfer. An optional trolley base compliments the package. The M1 controller range and Mold-Masters’ advanced control technology are said to have a proven track record for accurate control and robust reliability in service.
