MSZ50S Injection Blow Molding Machine

Technical Features

The single cylinder can open and close the injection mold and blow mold synchronously, making open and close mold faster and more efficient. The action of table up and down does not occupy the cycle during automatic production.
Servo hydraulic system with accurate control, energy saving more than 25%.
Horizontal injection system,achieve stable plasticizing and easy operation.
Single beam mold locking structure make mould loading more convenient.
Strong versatility, compatible with MSZ40/MSZ45/MSZ50H mold.
Stripping plate overturn pneumatically, safe and clean.


Electric preplasticizing,synchronous plasticizing can be realized. Linear guide for barrel movement, low resistance, high precision.
Electric stripping,senergy saving and clean.
Electric table rotation, high precision of rotation positioning.

Product Application

Pharmaceutical dry syrup bottles
Glue bottles
Health care hand sanitizer
Pharmaceutical eye droppers


Clamping parts

Special designed single crossbar dual-cylinder balance clamping system,for fast opening and closing mold while ensuring uniform distribution.

Rotation mechanism

Unique rotating mechanism design, and equipped with automatic lubrication system,ensure rotation precision be consistent.

Injection components

Alternative efficient plasticizing mixing screw, optimization of the injection unt,improve the injection stability and accuracy.

Hydraulic system

Equipped with electro-hydraulic servo system, the machine is running stable, low noise, high response and energy saving of 25% to 45%.

Barrel screw
Screw optimization design, clamp screw head assembly, with good plasticizing ability, wear resistance.

Processing principle

Injection Blow Molding Machine is a special designed machine with a rotarythree station index, after perform injection the perform will be sent to beblow station, then stripped for next processing like washing or filling neededby conveyor. It is suitable for PE, PP, PS, SAN, EVA, COC, PEEK, TPU PETG,PET etc material, bottles volume various from lml-I000ml.The l.B.M bottlehas a perfect neck finish and strict body thickness and weight, it is good forhigh quality packing like pharmaceutical, cosmetic, house holding,foodproducts packing industrial.
