The SCJC500×6 plastic blow molding machine developed by Shaanxi Qinchuan Machinery Development Co., Ltd. is used to produce six-layer plastic fuel tanks. The maximum product volume that can be produced is 500L, the maximum output is 620Kg/h, and the maximum die diameter is 550mm. The machine is co-extruded by six extruders. The extruder for recycling materials not only has a large throughput, but also has the function of cutting, crushing, and mixing evenly the unplasticized PA (nylon) or EVOH material in the recycled material.
The six-layer co-extrusion head is a six-layer continuous extrusion head. To ensure the tight combination of the six-layer melt, it is optimized and analyzed by foreign large-scale melt flow analysis software. The melt flow rate of each layer is relatively stable and consistent; the control point of the axial parison wall thickness is 100 points, which is more conducive to achieve uniform product wall thickness than the 64-point control and reaches the product standard (the thinnest part is ≥3mm).
· Molding machine has a clamping force of 120t. It adopts a four-cylinder tensioning structure to make the surface of the mold and the product even.
· The electrical system adopts high-function PLC control of two sets of world-famous brand products. Through the touch screen to achieve human-machine dialogue, 100-point parison wall thickness control and extruder control can be realized, and the control accuracy is high, which can ensure the long-term stable operation of the system.
· The main components of the hydraulic system and pneumatic system adopt the world famous brand products, which can ensure that the system does not leak oil under high pressure and can work stably for a long time. Because the hydraulic system uses large-capacity energy storage, long-term use can save electricity. This greatly reduces the user's production costs.
· The use of the world's famous brand of product feeding system can enable six extruders to achieve centralized automatic feeding, ensuring the stability and reliability of the feeding system.
