Hasung Introduces Advanced Jewelry Casting Machines for Precision and Flexibility

Hasung Unveils HS-VPC.S and HS-VCT3 for Jewelry Manufacturers

In June, Hasung, a prominent manufacturer in the jewelry casting machine sector, launched two innovative vacuum pressure casting machines: the HS-VPC.S and the HS-VCT3. These machines cater to specific production needs, offering enhanced capabilities for small-batch and high-precision jewelry casting.

Meeting Diverse Jewelry Production Needs

The jewelry manufacturing industry frequently deals with various production scenarios, requiring equipment that can adapt to different requirements. Independent studios and small to medium enterprises often seek compact solutions for small batch production, especially when developing samples or working with various precious metals.

According to a recent study on jewelry casting in the journal Special Casting Nonferrous Alloys, the success of jewelry production is closely related to controlling alloy properties and mold conditions. These parameters are critical to preventing casting defects. This insight prompted Hasung to create machines that can adapt based on production scale and design specifications, culminating in the HS-VPC.S and HS-VCT3.

Innovative Features of the HS-VPC.S

The HS-VPC.S stands out as a mini semi-automatic jewelry vacuum pressure casting machine, designed specifically for small-batch production in studios and workshops. Measuring 590×570×800 mm and weighing around 120 kg, it strikes a balance between compactness and versatility.

To accommodate diverse materials, the machine can process gold, karat gold, silver, copper, and various alloys. It also supports argon or nitrogen use as protective gases. This flexibility is vital for users needing to create samples or produce small quantities of jewelry without investing in larger machinery.

The Fully Automated HS-VCT3

For those requiring greater automation and a larger processing capacity, Hasung presents the HS-VCT3. This model features fully automatic operation with a user-friendly WEINVIEW interface and a Siemens PLC intelligent control system, ensuring precise control over the casting process. With a rated power of 12 kW and a melting time of just 2–3 minutes, it quickly adapts to production demands.

One of the highlights of the HS-VCT3 is its adjustable casting pressure, operating up to 4 bars. Designed for high-precision applications, it effectively produces intricate jewelry designs. The automated system enhances efficiency by centralizing multiple process steps, minimizing the need for manual interventions.

The two machines cater to different production volumes with differing specifications, allowing manufacturers to select the one that best meets their operational requirements.

The Advantages of Vacuum Pressure Casting

Vacuum pressure casting stands out in precious metal jewelry manufacturing as it significantly improves metal filling conditions by utilizing a vacuum environment and pressure differentials. During the casting process, molten metal is compelled to fill even the finest structures of a mold, substantially lowering the incidence of defects like bubbles and porosity.

The HS-VPC.S employs advanced technologies, including medium-frequency heating, automatic frequency tracking, and PID temperature control. The integration of melting and casting processes into a single unit, along with its built-in vacuum pump, facilitates efficient vacuum pressure casting.

With a maximum temperature threshold of 1500 °C and maximum pressure of 0.3 MPa, the HS-VPC.S offers robust capabilities for diverse jewelry production. In contrast, the HS-VCT3 simplifies the filling process with a double-chamber design, reducing gas consumption and minimizing alloy oxidation through a gas-wash procedure that replaces oxygen with inert gas.

Expanding Horizons with Hasung

With these new machines, Hasung reinforces its commitment to providing practical solutions that meet jewelry manufacturers' diverse needs. Founded in 2014, Hasung has established itself as a high-tech enterprise with a comprehensive range of equipment for precious metals, including casting and rolling machines, reflected in their extensive 5,500-square-meter production facilities.

As Mr. Xiang, the founder, states, “Our goal is to assist customers in achieving an optimal balance of flexibility, control, and efficiency in their production processes.” The introduction of the HS-VPC.S and HS-VCT3 is a testament to this vision, signaling a wider array of options for the jewelry manufacturing landscape.
