SSF720-K5 injection molding machines are applied to produce plastic parts injection weight within 100g, stable quality machine with wide applications.
Clamping unit: The platens were designed using Finite Element Analysis software, ensuring a stable and rigid clamping system. Five-point inward moving toggle system ensures high rigidity and precision for mold clamping and also reducing stress and stain effects;
The moving platen is fitted with adjustable slide support system to improve platen parallelism and provide better tie bar and mould protection and lengthen the working lifetime.
Chrome plated tie bars, made from alloy structural steel are designed and manufactured for high rigidity and wear-resistance.
Extended clamp opening stroke with larger distance between the tie bar’s to meet the special molding requirements.
Injection unit:  A wide variety of screws are available for different polymer processing requirements. Special engineering materials are used to manufacture the screws to ensure optimal quality and processing life;
High quality nitride or chrome plated alloy screw with a nitrogen-treated barrel provided anti corrosion with high wear resistance for an extended working life;
The injection unit incorporates a dual-pillar supporting system with balanced twin cylinder injection unit for evenly distributed force and rapid screw motion;
Nozzle alignment is provided using a simple mechanism with fine adjustment for accurate centering;
Hydraulic system: The hydraulic oil flow design applied modular block technology for rapid oil transfer and dynamic system response. Control valves are located in close proximity with each major control group.
Charge back pressure makes melting precise and stable, of which can meet all kinds of new products with different injection process.
World renowned control valves applied to precisely control every machine movement. Fixed pump system provides stable output, quick response, powerful strength.
Major hydraulic components and seals are sourced from world famous manufacturers providing high reliability and interchangeability.
Oil pipelines are positioned for aesthetic appearance and easy maintenance.
Control system: Screen protection function, extends the life of the screen
Super light emitting diode display status for input/output point, make it easier for operation and maintenance personnel to master system’s movement status
Set the keyboard lock function, prevent operators to make any changes of the stored information
Computer set and PID closed-loop controls heating temperature precisely, the temperature ranges from 0~399°C.
Complete close electrical control box, electrical components arranged neatly. Mutual interference, and has the function of dustproof and waterproof.
The control panel applies color screen technology, of which detect production process and display all kinds of malfunction analysis.
The latest computer system provides fast information response with user-friendly operation. 
The toggle system uses oil-sleeve bushes lubricated by an automatically control central lubrication unit which provides excellent lubrication quality to all points and extends the clamping unit working life.
There are 2 type of lubrication agent, one is lubrication grease, the other is lubrication oil, per customer's final products requirements, medical parts prefer to use lubrication oil to avoid any contamination.
