Features of BOLE EKH Series of Energy Saving Injection Molding Machine

Invention Patent — Central Clamping Toggle
1. High clamping force efficiency
  After sample survey, clamping force efficiency of BOLE central clamping toggle of BOLE central clamping toggle design can reach 100%, and traditional edge clamping toggle design. clamping force efficiency only can reach 80~85%.
2. Material Saving
  BOLE central clamping toggle design can save 2~5% material for 80% of customers mould (comparing to traditional edge clamping toggle design).
3. High accuracy, Less possibility of flash
  Mold open & close positioning accuracy: ±1mm
  Injection weight accuracy: ≤0.5%
  Less possibility of flash, save flash trim work
4. Offer good protection to mould and platens
  New designed clamping structure, bear averaged force, Less platen distortion, effectively extend mould life.
5. Big open stroke
  Larger open & ejection stroke comparing with other brand, much easier to install larger mould (especially for deep cavity mould).
Fully optimized hydraulic system, the system pressure rises to 17.5Mpa, improved injection pressure.
Third generation of hydraulic servo system, energy saving, the system response time is shorter. According to GB/T30200-2013 standard test, all types of BOLE machines meet the requirement of CLASS I-energy consumption ≤0.4kW.
The rigidity of mechanical part is improved, reasonable distribution of bearing point.
The rigidity of clamping part is improved, further prolong the life time of machine.
Optimized electrical cabinet design, conform to GB, CE, UL, KCS or other safety standard.
Electrical parts from famous international manufacturers, ensure machine with reliable performance.
EST controller is standard.
Plasticzing system originated from Germany design, and its efficiency improve 20% above the performance of other Chinese manufacturers. (Common plastic materials ABS, PS, PP, etc.)
Meet Custom-made requirement for complex technical process and special plasticzing solutions.
