Product Introduction
Heat setting is the key process in PP strapping production to "freeze" molecular orientation, relieve internal stress, and reduce thermal shrinkage. This production line is equipped with a 4.0-meter long, 0.6-meter internal width far-infrared sizing oven.
Far-infrared heating tubes provide high thermal efficiency and strong penetration, quickly and uniformly heating the tape. The oven is divided into multiple independently controlled zones, allowing different temperature profiles according to process requirements. The 100mm thick high-efficiency insulation greatly reduces heat loss, lowers energy consumption, and ensures stable internal temperature. A motor-driven door opening mechanism (1.5KW) facilitates operation and maintenance.
Customer Q&A
Q: What are the advantages of far-infrared heating over ordinary electric heating tubes?
A: Far-infrared radiation directly acts on the tape surface, with strong penetration and high heating efficiency, without excessively heating the air. This results in faster warm-up, more uniform temperature distribution, contributing to uniform crystallization and setting, while saving electricity.
Q: Is the 100mm insulation really necessary?
A: Absolutely. It keeps the oven outer surface cool, improving the working environment; reduces heat loss, saving about 20-30% of heating energy; and stabilizes internal temperature, making control more precise.
Q: What is the purpose of the door opening motor?
A: The oven door is heavy. Manual opening is strenuous and unsafe. The motor allows easy one-touch opening and closing, facilitating cleaning inside, threading, or maintenance. The door has a safety interlock that cuts power when opened.
