Induction Heating in the Jewelry Industry
Induction heating in the jewelry industry is a technology that utilizes the principle of electromagnetic induction to generate eddy currents inside metal materials in an alternating magnetic field, which then generate heat due to resistance. It is used in jewelry processing, including metal melting, welding assembly, and heat treatment.
● Meltable material
Hasung induction heating and casting technology and machines can be applied to various commonly used materials in jewelry. In addition to common precious metals such as gold, silver, and platinum, various K gold alloys can also be processed. In addition, some special jewelry materials, such as copper based alloys, silver based alloys, and various new metal composite materials, can also be melted well to meet the needs of different jewelry designs and productions.
● Methods, Technologies, and Processes
Induction heating technology: Hasung adopts advanced high-frequency induction heating principle, which generates a strong alternating magnetic field in the induction coil through high-frequency alternating current, causing eddy current to be generated inside the metal material, and then quickly heating and melting, with the characteristics of fast heating speed and high efficiency.
Casting process: Firstly, precision molds are designed based on jewelry, and then the selected metal materials are placed into the Hasung induction heating equipment's furnace for rapid melting.
After precise control of the casting process, liquid metal is injected into the mold cavity. After cooling and solidification, demolding is carried out, followed by fine processing of the casting, such as grinding, polishing, inlaying, etc.
● Advantage
Precise temperature control: It can accurately control the temperature within a very small range, ensuring that the metal melting state is uniform and stable, which is conducive to casting high-quality and high-precision jewelry products.
Energy saving and environmental protection: Compared with traditional heating methods, energy consumption is significantly reduced, and the heating process is clean with no harmful gas emissions.
High equipment stability: Hasung machines use high-quality materials and advanced manufacturing processes, ensuring stable performance and reducing production interruptions caused by equipment failures.
● User's experience
Jewelry practitioners generally give feedback that the operating interface of Hasung devices is simple, intuitive, and easy to use. Its rapid heating and precise casting greatly improve production efficiency and effectively shorten product delivery cycles. Moreover, the stability and reliability of the equipment also reduce maintenance costs, bringing good economic benefits and production experience to jewelry production.
Steps for Casting Jewelry Via Induction Casting Machine
To cast jewelry with an induction jewelry vacuum pressure casting machine, the first step is to design and start the plate. The wax plate is made by hand or 3D printing, and then the wax mold is trimmed and planted into a wax tree. The wax tree is then placed in a stainless steel cylinder and filled with gypsum and vacuumed to solidify. The gypsum mold is then baked and dried, and the metal material is placed in the melting chamber of the casting machine to melt.
The baked gypsum mold is placed in the casting chamber, vacuumed and protected by gas, and the molten metal flows into the gypsum mold cavity under vacuum and pressure. After cooling, the gypsum is blasted out of the casting and cleaned. Finally, the casting is subjected to subsequent processing such as trimming, polishing, mold holding, and inlaying to produce exquisite jewelry.
Benefits of Casting And Melting Machines
for Jewelry Manufacturer
Improving production efficiency: Traditional manual melting and casting of jewelry is time-consuming and labor-intensive, while casting and melting machines can quickly complete the melting and forming process of metal, greatly shortening the production cycle and allowing jewelers to produce more styles of jewelry in a shorter time, meeting market demand.

FAQ
1. Q: Does jewelry lose value when melted?
A: It will not lose its value because commonly used metals in jewelry, such as gold, platinum, silver, etc., all have inherent value. These metals have limited reserves in nature and possess good physical and chemical properties. For example, gold has excellent ductility and corrosion resistance, while platinum has high melting point, high density, and other characteristics. Their value is based on their scarcity and unique properties. Even if the metal is melted, its chemical elements and physical properties remain unchanged, maintaining its value as a precious metal.
2. Q: How Does Induction Heating Heat Jewelry？
A: Induction melting machines use copper induction heating coils to provide alternating magnetic current to the metal inside the coils. This alternating magnetic current generates resistance in the metal, causing it to heat up and eventually melt. Induction furnace technology does not require any flames or gases that may be harmful to the environment to melt metals.
3. Q: What is the process of smelting jewelry?
A: Design and layout-Material preparation-Melting metal-Casting molding-Surface treatment-Gemstone inlay (if any)-Quality inspection.
4. Q: How do you smelt jewelry with borax?
A: Borax mainly plays a role in assisting melting and removing impurities in jewelry smelting. The general steps for smelting with borax are as follows: Preparation work-Raw material selection-Add borax to remove impurities-Heating and melting-Purification and molding-Follow up processing.
5. Q: What flux do you use to melt jewelry?
A: Adding the following materials during the melting process of gold can improve its purity: borax, sodium carbonate, Saltpeter, Activated carbon.
6. Q: Can you provide customized services?
A: Of course you can! We focus on providing customized services to meet your unique needs. We have a professional team to follow up on the entire process from scheme design to product delivery, ensuring that every detail meets your expectations.
