In the manufacturing and application of high-pressure die casting molds, problems such as porosity, shrinkage, and heat treatment blistering in castings have long plagued the stable mass production of automotive structural parts, communication housings, and high-end aluminum alloy components. As customers’ requirements for internal quality, mechanical properties, and post-processing adaptability continue to increase, simply relying on mold structure optimization is no longer sufficient to completely solve these defects. At this point, the vacuum die casting machine becomes one of the core pieces of equipment for achieving high-density die castings.
As a professional high-pressure die casting mold manufacturer, Raidy mold understands the critical impact of vacuum systems on mold performance and casting quality, and provides stable and efficient vacuum die casting machine solutions tailored to different mold structures and product requirements.
What is a Vacuum Die Casting Machine?
A vacuum die casting machine is a device that rapidly removes air and gases from the mold cavity and gating system using a vacuum pump system before or during injection filling. Its core function is to reduce the air entrapment during high-speed aluminum filling, thereby significantly reducing porosity, shrinkage, and dissolved gas content inside the casting.
Compared to conventional high-pressure die casting, vacuum die casting effectively improves the density, mechanical properties, airtightness, and weldability and heat treatment adaptability of castings. It is particularly suitable for high-end structural and functional components with extremely high requirements for internal quality and stable mass production.
Raidy Vacuum Machine Technical Parameters and Configuration Advantages
The Raidy die casting vacuum machine series is specifically developed for high-pressure die casting technology. The equipment adopts 380V three-phase voltage supply, and the standard configuration of 2 main vacuum channels + 2 air blowing channels ensures it is stably applicable to different complicated high-pressure die casting mold structures and vacuum molds.
According to different configurations, the vacuum pump rating ranges from 63 to 100 mยณ/h, and it supports single pump and dual pump configurations. The equipment can be flexibly configured depending on different casting sizes, mold sizes, and production cycles to realize rapid, stable, and accurate vacuuming.

FAQ
Q1: What is the function of the vacuum machine in die casting?
A: The function is the quick removal of gases and air from the mold cavity prior to the injection of the molten metal, which minimizes porosity and shrinkage and maximizes the density and mechanical properties of the casting.
Q2: Is faster the better in die casting?
A: The answer is not necessarily faster. The critical factor is not the speed, but the capability to quickly and stably create the cavity vacuum state in the die casting process and match the volume and structure of the high-pressure die casting mold.
Q3: How do you ensure the stability of the vacuum performance in mass production?
A: The stability is ensured through multi-channel design and cavity vacuum state monitoring, which eliminates the problem of quality fluctuations due to pipeline and filter problems.
Q4: Can a die casting vacuum machine solve the porosity problem in the long term?
A: Yes, as long as a suitable model is chosen for the die casting machine, the porosity can be continually reduced along with the shrinkage in the long term, effectively preventing bubbling during heat treatment.
Q5: Do different molds require different models of vacuum machines?
A: Yes, because different molds for high-pressure die casting come in different sizes and complexities in terms of die casting machine requirements for achieving quality in die casting products.
