Technical Features
1. Excellent temperature uniformity through optimized modulize hot zone design.
2. The heating elements adopt unique non-ceramic supporting technology. It can be used for five years without any insulation problem.
3. The inner trolley is overlap-type stretchable structure with frequency converting function. It has a stable transportation speed with "slow-fast-slow"steps, which makes the transportation time very short.
4. Build-in heat exchanger and forced gas cooling type contribute to the uniformed and high-flow-rating jet gas, which eventually makes the cooling speed very fast.
5. High volume oil tank and hot oil cooling by external circulation and heat exchanger has a better cooling effect.
6. Two cooling types, oil stirring and oil injection cooling, are used for various kinds of products, which makes the product have less deformation.
7. Auto load cart, remote control, loading and unloading need only one operator.
