China Sandwich High Efficiency Energy Saving Injection Molding Machine

Sandwich injection molding process is a newly developed creative plastic processing method.One set of additional composite nozzle and barrel is added to the traditional plastic injection molding machine to form an independent barrel.During the injection process,this double barrel can concurrently inject two types of molten plastic via the same nozzle,into the mold to achieve double material simultaneous injection.The outer layer of the mixed molten plastic is caalled skin material,while the inner layer is called core material.
Some of the important features:

Clamping system: Faster response, stable and high rigidity

Injection system: Accurate and flexible, lower rejection rate

Control system: Computer and simple operation,molding data memory system

Power system: Energy saving, high efficient and precise

metal parts:The thickness of our frame, metal plate and wallboard are thicker than other company.


Other Information

Show High Precision: The accurate injection positioning,pressure, speed and pressure maintaining,to ensure the repeatability error of injection accuracy less than 0.3% to achieve precision molding.

Super EnergySaving Features: Compared with standard injection machine,the energy saving rate can reach 40%-70% for the same plastic production.

High Efficiency: Compared with standard machine,the total efficiency can increase by 10% and dragging capacity is can increase by18%.

High Response System:The system acceleration and deceleration performance is quite agile and force&speed regulation is very sensitive.The sampling processing speed can reach 100KHZ and system quick start time can reach 0.05s.

Maintain Stability and Reliability:The pressure or speed is stable and switch of pressure maintaining is smooth and accurate.

Low Oil Temperature:Avoid high pressure unloading and low oil temperature situation during operation.Improve the operation performance.promote using efficiency and save a large quantity of cooling water.
