1、The U-type extrusion blow molding machine uses the counter-type clamping frame structure and cooperates with the Taiwan famous factory linear guide rail; the movement of the mold base is faster and more stable, and the clamping force is stronger and more uniform;

2、6 blow pins can be realized at the same time perpendicular to the mold blow pin hole;

3、Computer intelligent control system, easy to operate, set up and modify production procedures;

4、The inside of the die head is treated with deep mirror surface, the curve flow path is smooth, no dead angle, no carbon deposit;

5、Strengthening the hardened cold processing screw, the screw barrel is resistant to wear;

6、The Japanese CNC machine tool is used to produce all the components. All the mounting surfaces of the Mazak six-sided machining center are used for one-time processing. The hydraulic, pneumatic and electrical parts of the famous brand are imported to ensure the rigorous process and stable and reliable quality.


Performance characteristics

1、This extrusion blow molding machine is suitable for the production of plastic hollow products of PE, PP, EVA, ABS, K material, TPU, nylon and other materials below 5L;

2、Computer intelligent control system, Chinese and English operation interface;

3、According to the characteristics of different plastics, different screw and die mandrel and runner style can be designed;

4、The die refueling, color change, slagging, disassembly and cleaning are convenient, and the parison control of the tube blank is very uniform;
5、The double proportional valve controls the flow rate and pressure of the oil passage, the reversing valve controls the flow direction, and the brake of the deceleration valve is smooth and quick;

6、The toggle-type clamping structure is designed by the front and back colleagues of the template center to ensure the uniformity of the clamping force;

7、Liftable extrusion platform for easy adjustment of the length of the blank;

8、CE security standard design, focusing on user safety;
9、Japanese inverter adjusts the screw speed to save energy and save energy;
10、Automatic lubrication system, automatic alarm function, pay more attention to user experience.
