High Speed Injection Molding Machine VR

Precision Built, High Speed PIM Machinery

Victor Taichung VR Series injection molding machine has been developed by fusing of merits of hydraulic injection machines (low maintenance-free operation, long life, and low cost) and electric molding machines (energy-saving, high-velocity injection, quick response, high repeatability, and low operation noise)

The Innovative New Servo Motor

The innovative new servo motor with high-effect pump system, achieves energy-saving (Option) operation and quick response equivalent to all electric molding machines.

Characteristic

• Injection screw ACM2 German material
• Surface hardness: 900~1100 HV
• Processed by Nitride (500~520°C for 72hrs)
• Nitrided thickness: 0.4~0.5 mm
• Piston rod uses S45C steel which has excellent strength
• Piston seal uses German make Merkel to reduce the leakage and extend piston life.
  

Energy Saving Advantage (ES Option)

• Energy saving - Almost equivalent to all electric molding machines.
• Quick response - Injection response time (Standard mode).
• Stability in low-velocity/low-pressure & wide range - Injection velocity: From ultra-low to high velocity range.
• Linearity - Excellent linearity in both injection velocity and injection pressure.
• Excellent injection holding pressure performance - Capability in sustaining high injection holding
  pressure longer (as compared with all electric types).
• Reduction in the amount of hydraulic oil.
• Silent! (Low noise) Almost equivalent to all electric molding machine.
  

Bi-metallic Material (Optional)

SKD 61 base material. Excellent wear-resistant, corrosion resistant screw & barrel for the processing of materials with fiber additives and also fire retardant materials.

Victor general purpose screw and barrels can process any kind of material like PE, PP, PA, ABS, AS. We also supply an optional screw & barrel for engineering materials like PC, PBT, PET, with an L/D ratio from 18, 20, 22.

This multi-notch non-return valve offers improved reaction times and high flow rates. Also improves cycle times and increases product precision.

Utilizing the High Wear and Corrosion Resistant Ionnitrided Screw

The VR Series injection unit, utilizing the high wear and corrosion resistant ionnitrided screw and barrel, provides the injection volumes and plasticizing capacities necessary for the manufacture of precision products. With high injection stability and excellent mixing capabilities, this newly developed injection unit allows for the use of a wider range of materials. It all adds up to unit that will stay the course, giving consistently high quality and product output.

New Low-friction Linear Guided

High speed and fast acceleration functions.

Heavy Duty, Rigid, Clamping Unit

All VR Series machines feature a unique, ultra-reliable, five-point toggle clamping mechanism which is characterized by an almost ideal kinematic velocity feature.

High Precision Clamping

This high precision clamping unit is designed and analyzed using the latest in computer software, i.e. CAD & CAE. The large cast iron platens are extremely robust and with widely spaced tie-bars to 
accommodate the largest of molds. They have optimum rigidity that matches the current need in precision molding and which minimizes mold deflection caused by clamping force and cavity pressure.

Eliminate Deflection and Oil-free

The large, square cast iron platens virtually eliminate deflection. The bushings a re manufactured from graphite impregnated phosphor bronze. Designed to run totally oil-free, there's no chance of contaminating molds, and maintenance is limited to long periodic greasing.

Material

• Platen: Meehanite casting FCD 55
• Tie bar: NH48MV (from Japan)
• Toggle pin: SCM21 (hard chrome plating)
  

Advantage

• Machine life = 15 years more
• Eliminates the oil pollution
• Saves maintenance time
  

Prevent of Overloading by Force

Mold height adjustment, which is the bull gear system, is operated by a hydraulic motor and when co-ordinated with a monitoring program proceeds to prevent the possibility of overloading by force and cause machine damage.

Energy Saving System (Option)

The VR Series adopts logic valves in its hydraulic system circuits. The logic valves give high response performance in injection and mould travelling stages and offers 5% energy reduction due to low-pressure loss, and can guarantee a long service life. Less energy loss means lower heat build-up in addition to a substantial reduction in the requirement of cooling water. This is further help automatic regulation of the hydraulic oil temperature.

VR ES Energy Saving System (Injection Close-loop Feedback Control)

The pressure output signal of servo driven pump is measured injection cylinder and feedback to P/Q control module for closeloop pressure compensation. The flow output signal of servo motor is measured and feedback to P/Q control module for flowcompensation to get precision control.

Comparison with Traditional Fixed Pump with Constant Speed

Example: Load sensing
72.3% energy saving
Model: VsES-60T

75s cycle times
const. speed (15kW): 2.9 kW
SVP: 0.8 kW

Hybrid Hydraulic Control (Option - Servomotor Pump)

VR Series injection molding machine every moving steps require pressure and flow control by high-effect pump collocating with powerful permanent-magnet synchronous servo motor. This series machine is availability of energy saving up to 60% as compared with general hydraulic machine.
