Special Notes: All data below is subject to change without prior notice due to the continuous improving of our technology. DADAU DDSJ350X6C , 6layer Fuel Tank Blow Molding Machine Characters&Parameters DADAU's 6-layer fuel tank blowing machine DDSJ350X6 has obtained 7 national patents till the end of 2015. It has passed the identification of Jiangsu province as the new high-tech product with conclusion that the technology was domestic leading, and authorized as the 1st major heavy equipment in Jiangsu Province, that's also why dadau has already provided to the domestic market 11 sets of such 6-layer fuel tank machine by far, and another 1 set is under discussion. Those belongs to DADAU only and none other blow molding machine company can compare.DDSJ350x6C, developed by Jiangsu Dadau Machinery&Electric Co.,Ltd., is to produce 6 layer fuel tanks with capacity up to 100L. It is consisting of extrusion systems composed of 6 different effective extruders, co-extrusion die head, clamping unit (forming machine), blow unit, manipulator, clamping mechanism, frame, safety device, centralized feeding system, electric control system, hydraulic system, pneumatic system, weightlessness weighing system. Etc. Its components and parameters are as below: 8.1 Basic parameters 8.1.1 Max. Fuel Tank Capacity: 100L8.1.2 Max.

Layer A | base layer or inner layer | New material HMWHDPE | 35%~40% | | it's the main body of the fuel tank whose function is to assure the strength, stiffness and stablility, and also as functional layer in a degree. |
Layer B | recycling layer | recyling PE or mixture of the recyling PE and new HMWHDPE | 35%~45% | as high as 50% | To save cost by collecting some little crash and NG during the production. Meanwhile, it's no matter how many times it recyles. |
Layer C | outer layer or decoration layer | New material HDPE and any assistants | 12%~15% | as high as 20% | The outer layer also has a certain strength and stiffness. Besides, color master batch cal also be input to have different colors of the fuel tanks. Or,Anti ultraviolet agent and other assistants can also be applied to help with environmental adaption of the fuel tanks. |
Layer D&E | adhesive layer or connecting layer | TIE | 2%~3% | can be adjusted to 1% | To better connect the functional layer with the base layer, recyling layers. It's the key of multi-layer co-extrusion. |
Layer F | functional layer or EVOH Barrier layer | EVOH | 3.5%~4.5% | can be adjusted to 1% | functional layer is the key layer of high barrier. It stops the useful material of the fuels going out of the tank, and also stops the air or moisture coming inside the tank. |
