Advantages of Hydraulic Injection Machines:
  • Lower initial price: The base price of these machines are significantly less than its alternatives.
  • Cheaper parts: If a part on the machine needs to be replaced due to damage or the parts life-span reached its limit, the replacement parts are lower cost and easier to find.
  • Stronger parts: The hydraulic parts of the machine are more resistant to wear and tear—they are built to last.
  • Power: Hydraulic molding machines have exceptional clamping force.
  • Simple: Hydraulic molding machines have simple structure and with easy maintenance.
  • Easy Using: Hydraulic injection machines mostly are easy to set high-pressure clamping force.
Advantages of Electric Injection Machines
  • Energy efficiency: Electric injection molding machines only use energy when in action—meaning the motor output is only equal to that of the load requirements.
  • Less-down time: There is no chance of leakage from oil. Also, no oil use means no filters to be replaced, which means consumable expenses are less.
  • Faster process: These machines are digitally controlled, meaning the process is entirely repeatable and needing no supervision.
  • Clean operation: Since there is no use of oil for this machine, it is safe for use if you are manufacturing medical and food packing parts. Typically, these parts should be created in a clean-room area.
  • High precision and high reproducibility:Injection control (such as pressure and speed) can be controlled in fine units, the control of the injection device is accurate and the molding conditions can be stabilized,highly accurate control and highly accurate monitoring system. It can perform difficult operations such as multi-stage extension of the hydraulic system, and can control the extension
  • Quiet & Eco-friendly
Advantages of Hybrid Injection Machines
  • Diversity: the possible combinations for hybrid injection molding machines open up new degrees of design flexibility.
  • Best of both: Hybrid molding machines combine the energy savings and accuracy of electric molders with the force-generating capacity of a hydraulic unit.
  • Replaced motor: Hybrids have replaced fixed-speed DC pump motors with variable-speed AC drives so the pump only operates when required and uses the necessary amount of oil for process efficiency.
  • Less downtime: These require less maintenance and experience less downtime than an all-hydraulic or all-electric molding machines.
  • Price point: Falls nicely between all-hydraulic and all-electric molding machines, making it an affordable option. Especially for medical device manufacturers.
  • Energy-efficient,low-temp, closed-loop process
  • Exceptional clamping force
  • High-precision production and repeatability
  • Accommodates thick-and thin-walled parts/design variety
