U20
Product of 25ton class can cast at parting injection
U20 Die Casting Machine has the capacity to hold dies up to 200×215mm in size, allowing for the production of High Precision" Optical Base" components and mobile phone parts. Using the optional higher speed extractor, accurate handling of the casting reduces possible damage toboth the die and casting products.
U Series Features
Less air trapped in the metal flow during die fill, it makes the casting parts excellent.
With parting injection system, it makes less re-melting material and can reduce a lot of re-melting cost.
Sprueless system it makes die opening stroke shorter.
STANDARD
| ▶ Parting injection |
|---|
  The sprueless casting has been resulted by direct injection of metal at the parting line.The parting line injection system has resulted in constant higher cycle casting by reducing areas for air entrapment in the casting. |
| ▶ Touch panel monitor |
|---|
  The standard equipped touch panel display makes easy management of machinepossible.It assists by displaying optimum settings for the various kinds of die, monitoring the machine performance, management of injection parts and stores the alarm records.Multi Languages: multiple languages may be displayedthis is an option.(Languages displayable: Japanese, English, Chinese, Korean and Thai ) |

OPTIONAL EQUIPMENT
| ▶ Product take-out apparatus |
  Accurate detecting and handling of the casting reduces possible damage to both the die and casting. |
| ▶ Injection waveform monitor |
  Assists the operator in obtaining the optimum setting of injection plunger position, injection speed and pressure. Adopted a long-life non-contact position sensor. |
| ▶ Medium blow spray device |
  High speed inner spray device corresponding to the parting injection system. The die lubricant is reliably sprayed onto the complex-shaped die without slowing the cycle time. |
