Six and seven layers extrusion blow molding machine DHB-M120,DHB-M280 The extrusion system of six to seven layers co-extrusion blow molding machine consists of 6-7 sets of extrusion and composition, machine parts and screws adopt high quality nitride alloy steel, have high surface hardness, long service life and good quality of plasticizing, which is suitable for processing high molecular weight polyethylene. The pressure sets on the extrusion system can make sure the stability of material base of the continuous co-extruding die. Ensuring six or seven layers of resin completely melt, and using the latest international composite superimposed multilayer flow design, make the flow smooth and has no dead angle, the material and color piece can be changed, the material base is of good quality. Advantages of automatic extrusion blow molding machine: In the auto industry, plastic seat box has the advantage that the metal fuel tank can’t take place. Plastic fuel tank is with high safety, against the impact, corrosion, explosion, which the metal fuel tank can’t be compared to. The plastic fuel tank is 30%-50% lighter than that of the same specification. The machine processes HMWHDPE as the grass roots. EVoH is such plastic fuel tank with versatile layer,high barrer, complex shape which is six-seven layer, can produce varies hollow products requested as high barrier . Advanced processing equipment: Introducing advanced technology form Germany,Italy,Japan etc. Involving advanced design and production of super large-scale blow-molding machine and engineering management capability. Holding over 40 items Patent Technologies. After sales service: With good brand reputation and attitude of customer-centric, we invite special technologists responsible for after sales. Service hotline is 24-hour on call. Fast response: domestic call is handled within 12 hours. International call is handled within 20 hours.
