B. Zjn-ii plastic injection molding machine is designed and developed by our company on the basis of the second generation plastic injection molding machine and absorbing advanced technology at home and abroad. B. Zjn-ii plastic injection molding machine and mold adopt dual-mode alternating molding, with higher working efficiency; B. When workers operate the mold closing of zjn-ii plastic injection molding machine, they need to press two mold closing buttons with two hands at the same time to avoid reaching into the middle of the mold for rapid mold closing and play a protective function.

Screw pre molding, quantitative, limit feeding, full hydraulic fast and slow mold closing. The total pressure valve adopts double proportional type, with uniform stress distribution, accurate low-pressure protection, smooth and excellent whole stroke. Multi stage temperature control, multi-stage injection pressure, firing speed and back pressure stepless adjustment; It has seat in and seat out function, which is convenient for mold adjustment and material pipe cleaning; Large mold locking force, stable mold movement, electrical interlocking, smooth, beautiful and reliable injection head; With small floor area; Fully enclosed main components; The mould has the advantages of convenient disassembly and assembly.

Shoulder mold: diameter of pipe Φ 12.7mm— Φ 60mm； The shapes are oval and round, and can also be designed and manufactured separately according to customer requirements; Thread shape can also be designed and manufactured according to customer requirements.
