In the existing die casting method, internal quality defects due to fast charging have long been a concern. This device is a device that forcibly exhausts gas or air generated during the main bath by suctioning the cavity inside the mold through vacuum. As a result, problems such as the quantity, size reduction, and unformedness of internal air bubbles are solved, and automobiles. It is used in many areas such as parts, cylinder blocks, transmission cases, oil pumps, water pumps, head drums, case covers for equipment, and thin products.

• With a large amount of vacuum pump exhaust, air inside the cavity is exhausted in a short time to rapidly decompress the internal pressure.
• Since the vacuum degree inside the mold cavity is displayed, it is possible to check the mold fitting state, whether the suction line is blocked, and the filter is clean.
• Two or more vacuum suction ports may be mounted, and in the case of a two-cavity mold, each cavity may be separately connected.
• It stores mold vacuum pressure data for each shot and can be output as an EXCEL file.
• Additional functions such as multi-stage vacuum /external valve / suction flow / humidity sensor may be added.
• Anyone can easily use it by collecting and supplementing the strengths and weaknesses that have been experienced for more than 20 years in the die-casting field.
• It can be used immediately with one connector connection and is easy and fast to move to another machine.
