Hirate America show LS Mtron All Electric Injection Molding Machine at the Plastec West 2018

Hirate America, Inc. displayed the LS Mtron All Electric 120 ton WIZ-E Injection Molding Machine at the 2018 Plastec West at the Anaheim Convention Center. The machine is manufactured in South Korea by LS Mtron which is the 15th largest company in South Korea and targets injection molders looking for high quality and long term reliability with good performance and economical price.

The machine ran a Dauntless Industries 1 cavity polypropylene frisbee mold.

The machine comes standard with many features like double center press moving platen, T-slots in platens, dual air blow offs, ceramic heater bands, bimetallic screw and barrel, robot SPI or Euromap interface and auxiliary power ports.

LS Mtron improved on tie bar distance and extended daylight after listening to the US customers requests. Tie bar distance is extended on the horizontal 7% to 17% and vertical 2% to 15% compared to the previous model. Daylight is extended 3 to 20% compared to the previous model.

The machine features the new “Center Press” type moving platen to provide high stiffness to prevent platen bending which is always debated with toggle machines. This design provides equal clamping force across the platen when molding.

Also compared to the previous model the injection volume was increased 13% to 27% throughout the line.

The machine features simultaneous actions by separate control of all of the servo motors. This can reduce cycle time by opening the mold while charging and recovering and you can fire the ejectors while the mold is still opening and injection during pressurization.

As an option for machines 18 to 400 tons high speed injection is possible at 500mm per second by applying a strong and quick response AC servo motor.

The injection unit utilizes the double shaft nozzle touch structure for a stable nozzle touch and the forward and backward speed was increased 2.8 times compared to previous models. The new design improves platen parallelism, prevents resin leakage and machine lifespan is increased.

 

LS Mtron has service technicians across North America and offers local parts and technical support.

Significant Energy Cost Savings With Portable Chillers

Standard fixed speed compressors on chillers use a hot gas bypass valve that bypasses hot discharge refrigerant gas back into the compressor to simulate 100% load. This keeps the compressor running at full speed at all times regardless of the actual load. As an example, this means that if you have a 10 TON chiller and have 10 machines that each require 1 TON of chilling, or 2 machines that require 5 TONs each, you will be running your chiller at 100% capacity, regardless of whether you have 8 of your 10 machines running (80% load) or 1 of your 2 machines running (50%) load. With this example, the chiller will be costing you a fixed amount on your energy bill regardless of how many of your machines are running.

Thermal Care introduced the first portable chillers with a variable speed compressor on their 10 TON and 20 TON portable chillers.  It allows the compressor to reduce the actual output from 100% down to 30% by reducing the speed of the compressor while utilizing hot gas bypass to bring the load from 30% all the way down to 0% without shutting off the compressor.  As shown in the graph below, the energy savings often result in less than a 1 year return on investment.

Key Features:

  • Touch Screen PLC with full diagnostics
  • Totally enclosed, air-over (TEAO) low-noise, energy-efficient fan(s)
  • Removable tools-free access door
  • Power 3-phase error alarm
  • Warranty – lifetime controller replacement ($175 after 5 years)
