Gold & Platinum Jewelry Casting Equipment for Independent Studios

Since its establishment in 2003, Yihui Casting has been deeply involved in the field of precision casting for jewelry for 23 years. It has helped over 10000 jewelry factories and designer studios worldwide complete production line construction and process upgrades. Relying on independently developed K gold/platinum dedicated full process precision casting equipment, mature standardized process system, and designer exclusive full cycle empowerment services, Yihui Casting has created a lightweight, zero threshold, low loss, fully closed-loop one-stop solution for K gold/platinum high-end custom studios targeting the core pain points of independent designers.

The plan covers the entire process from studio space planning, mini production line construction, equipment matching, K gold/platinum exclusive craft teaching to design implementation and commercial empowerment. It does not require industry craft experience, large-scale site renovation, or high paying hiring of senior technicians. Designers can master core operations from scratch in just 3 days, perfectly adapting to 18K gold/14K gold, PT950/PT900 platinum full materials, covering all categories of wedding ring customization, high-end jewelry, designer brand styles, and IP co branded styles. It also takes into account 1-piece customization and 3-50 piece small batch production scenarios, completely solving the core problem of designer creativity implementation, helping designers achieve independent and controllable creativity, quality control, cost control, and delivery, and creating high premium products. The original designer brand.

Domestic high-end jewelry customization market has entered a period of explosive growth for designer brands. By 2025, the domestic jewelry customization market will exceed 280 billion yuan, with K gold and platinum high-end customization as the core categories of designer brands and becoming the core engines of industry growth

According to the "White Paper on China's High end Jewelry Customization Industry 2025", the domestic K gold/platinum designer customization market will exceed 76 billion yuan in 2025, with a compound annual growth rate of 31.8%, far exceeding the growth rate of traditional gold products. Independent designer brands will contribute 62% of the market growth.

Small niche designer brands, wedding ring customization, IP co customization, and personalized commemorative jewelry have become core demands. Over 78% of high-end jewelry consumers consider "designer original design" and "exclusive customization" as the core factors in their consumption decisions, and the premium ability of designer brands is 3-10 times higher than that of traditional factory goods.

Cross border e-commerce and social media channels enable independent designer brands to directly reach global consumers. By 2025, the cross-border export scale of designer brand K gold/platinum jewelry will exceed 12 billion yuan, with an annual growth rate of over 58%, becoming the core trend for jewelry cross-border overseas.

But for independent designers, the barriers from creativity to commercial implementation are extremely high: according to the "2025 Jewelry Designer Industry Survival Report", over 82% of independent designer studios have encountered development bottlenecks within one year of establishment, with a one-year closure rate of 57.3%. The core problems are low design implementation and restoration, out of control quality control of outsourced processing, high sampling costs and long cycles, opaque precious metal losses, limited environmental compliance, and weak ability to undertake small batch orders. More than 90% of designers' core energy is consumed by communication, rework, and quality control issues with contract factories, making it difficult to focus on creative design itself, ultimately falling into a vicious cycle of "good creativity → difficult implementation → poor quality control → poor reputation → low premium".

Outsourcing may be practical during the early stage of a jewelry brand, but it can limit sampling speed, process control and small-batch flexibility. A compact in-house casting setup gives designers greater control over prototype development, alloy handling, production scheduling and finished-product inspection.

Yihui Solution Positioning and Whole Process Logic

Is This Jewelry Casting Solution Right for Your Studio?

Complete Lost-Wax Jewelry Casting Workflow

A reliable jewelry casting line must coordinate every step from pattern preparation to final inspection. Yihui configures the equipment as one connected workflow according to the customer’s alloy, flask size, casting-tree weight, product detail and required batch frequency.

1. Jewelry Design and 3D Printing

Produce high-resolution castable resin or wax patterns for prototype development and customized jewelry designs.

2. Wax Injection and Tree Assembly

Replicate approved designs for repeated small-batch production and assemble suitable sprue systems.

3. Vacuum Investment Mixing

Prepare investment slurry under vacuum to reduce trapped air and improve mold consistency.

4. Programmable Burnout

Remove wax or resin and prepare the flask using a controlled heating and holding program.

5. Gold or Platinum Casting

Select a compatible vacuum-pressure or centrifugal casting configuration according to the alloy, required temperature, flask size and casting weight.

6. Devesting and Cleaning

Remove investment residue while protecting prongs, recessed structures and fine surface details.

7. Grinding and Polishing

Remove sprues and burrs before magnetic finishing, buffing and ultrasonic cleaning.

8. Metal Analysis and Final Inspection

Verify alloy composition, surface condition, dimensions and casting quality before delivery.

Gold vs Platinum Jewelry Casting Requirements

Do not select a casting machine only by its stated maximum temperature. Alloy compatibility, crucible material, temperature measurement, casting force, flask size and atmosphere control must be evaluated together.

Frequently Asked Questions

Can one casting line process both gold and platinum?

Some supporting equipment can be shared, but the melting and casting configuration must be verified for the actual alloy. Platinum requires a higher-temperature system, compatible crucibles, suitable temperature measurement and appropriate casting force.

Should I choose vacuum-pressure or centrifugal casting?

Vacuum-pressure casting is commonly selected for gold, karat gold and silver jewelry. Centrifugal casting is often selected for platinum and other high-temperature or lower-fluidity alloys. Final selection depends on the alloy, flask, casting weight and jewelry geometry.

What equipment is essential for a small jewelry casting studio?

A practical setup normally includes pattern-making or 3D-printing equipment, an investment mixer, a burnout furnace, a compatible melting and casting machine, devesting equipment and basic finishing tools.

What information is needed before configuring the equipment?

Please provide the alloy, normal and maximum casting weight, flask size, batches per day, most difficult design, available voltage, cooling conditions, protective gas and workshop dimensions.

Can the production line be expanded later?

Yes. A studio can begin with essential casting and finishing equipment, then add wax injection, higher-capacity burnout, additional polishing systems or metal analysis equipment as production increases.

Do you provide installation and operator training?

Installation, commissioning, remote guidance, operator training and process support can be provided according to the selected equipment package and project location.
