The basic principle of PMT-350 machine was to have a laboratory machine which has exactly the same possibilities and characteristics like a production STENTER machine. PMT-350 is a continuous operation apparatus suitable for drying, curing, continuous dyeing of sample.The test fabric is passing through the vertical type padding mangle ,then lead into infrared zone and hot air chamber by rotating pin chain, the infrared preheater fitted in front of hot air dryer including 12 infrared heater with reflecting plate arranged in upper and lower to improve working efficiency and also prevent test fabric from dyestuff migration in testing.
