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.

Optional

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

Product Application

Advantage

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

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

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

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

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

Processing principle

Injection blow molding machine has an accurate three-station rotary table design.After preform injection, the preform will be rotated to blow station and bottle forming, finally bottle rotated to stripping station.The bottles can be packaged directly or transported by conveyor to the next process.Because of the precise design of the mold, the I.B.M bottle has perfect neck, precise dimension, uniform wall thickness, which can meet high standard packaging needs of pharmaceutical, chemical, cosmetic and food packing industry.The I.B.M is suitable for PE, PP,PS, SAN, EVA, COC, PEEL, TPU, PETG, PLA etc material, bottle volume various from 1ml-1000ml.It is a professional equipment for high-efficiency packaging manufacturing.
