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 to
both 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
U_Series U_Series
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.

▶ Gooseneck
U_Series U_Series
Using a check valve system the molten metal moves to the tip of the nozzle thus reduces air entrapment, which produces a high quality casting.It is special type Gooseneck only available on U series machines.

▶ Touch panel monitor
U_Series U_Series
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
U_Series U_Series
Accurate detecting and handling of the casting reduces possible
damage to both the die and casting.

▶ Injection waveform monitor
U_Series U_Series
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
U_Series U_Series
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.
