SW-PVC series injection molding machine is improved in terms of characteristics of PVC-related raw materials. It uses an anticorrosive and high wear resistance bimetallic barrel set to reinforce long durability. In addition, its cooling fan device could effectively control heating temperature of barrel set, for avoiding easy burning circumstance of PVC material occurring inside the barrel. PVC series is more appropriate useful for pressure fitting production. Its machinery features are described as follows:

Clamping Unit

• Equipping a five-point high speed toggle mechanism for ensuring fast mold clamping, extending clamping stroke, stabilizing movement of clamping mechanism and increasing forming rate of finished articles.
• Tie bars are nitriding and thermal refining to perform high rigidity, better wear resistance and equal distribution of clamping force.
• Clamping and ejector strokes are precisely controlled by linear transducer to assure high accuracy of position.
• High speed toggle mechanism is used with differential hydraulic circuit for shortening forming cycle time and saving power.
• Low-pressure clamping device is equipped to protect mold.
• Hydraulic and electric safety devices are used for securing operators' personal safety.
• Usage of proportional flow valve is to ensure stability of clamping circuit.
• Integrated hydraulic circuit is to reduce oil temperature and loss effectively.
• Automatic mold height adjustment system.

Injection Unit

• Usage of double hydraulic cylinder aims for achieving better effect of mold adjustment, avoiding material leakage due to high speed or high pressure injection and shortening injection stroke.
• Anticorrosive and high wear resistance bimetallic screw set.
• Use of cooling fan to control barrel temperature.
• Multi-stage settings of injection speed, pressure and position for different kinds of delicate articles.
• Injection and screwing strokes are precisely controlled by linear transducer to ensure high accuracy of position.
• Screw cold-start protection is functioning as heater bands have not done setting temperature yet.
• PID temperature control

Microcomputer Unit

• Microprocessor controller contains 100 sets of molding data and function of breakdown-diagnosing.
• Multi-stage shot and injection pressure controls.
• Usage of colorful LCD monitor.
• Alarm messages of auto-diagnostic and maintenance.
• Display with animations is to easy observe pressure, time, speed and position of each mechanical function.
• Electrical components are CE Marking approval.
• Interfaces of input and output states are used to monitor machinery situation at any moment.
• Recording last 12 molds' parameters of time, temperature and position to control forming rate and adjust anytime.
• Several pages of mechanical function are friendly to operate.
