Star Harvest Jewelry Factory
20+ Years of Excellence
20-Day Lead Time
50,000+ Monthly Capacity
Moving from a boutique design to global distribution requires a jewelry factory that understands consistency.
Many brands struggle with quality drift during scaling; Star Harvest eliminates this through:
1:1 CAD-to-Product fidelity
Vertical integration from R&D to packaging
Full compliance with international standards.
Built for Precision & Scale
Our facility utilizes state-of-the-art tech to ensure every piece meets the rigorous standards of premium jewelry houses.
By optimizing electroplating formulas (such as cyanide-free gold plating) and vacuum plating (PVD) processes, we achieve precise control of coating thickness (±0.1μm), color stability (△E≤1.5) and wear resistance (5,000 steel wool tests without bottom exposure).
Real 14K/18K Gold Vacuum Plating (Thickness: 0.1μm – 2μm+)
We offer a variety of jewelry settings for stones, such as pave, bezel, and claw.
2-Year Tarnish Resistance (depending on plating spec)
Making a mold is the first step in jewelry manufacturing, which directly affects product accuracy and subsequent production efficiency. We use highly elastic silicone mold technology to perfectly replicate complex design details and provide stable and durable production molds for brass and stainless steel jewelry.
Treeing (also known as “wax tree assembly”) is a key step in splicing the trimmed wax model to the wax rod according to the requirements of the casting system. This process directly affects the metal fluidity and yield rate during casting, and is especially suitable for the mass production of copper and stainless steel jewelry.

Sand casting is a small and medium-sized jewelry manufacturing process that uses sand molds to form jewelry. It is suitable for mass production of copper-based alloy and stainless steel jewelry. This process has low cost and fast mold turnover, and is particularly suitable for products with rugged or retro styles.
Dewaxing is a key step in lost wax casting, which directly affects the surface quality and detail restoration of the casting. The wax pattern is removed through precise temperature control to provide a clean cavity for subsequent metal pouring.
Making a mold is the first step in jewelry manufacturing, which directly affects product accuracy and subsequent production efficiency. We use highly elastic silicone mold technology to perfectly replicate complex design details and provide stable and durable production molds for brass and stainless steel jewelry.
The assembly process is the final stage of jewelry production, which directly affects the integrity and wearing comfort of the finished product. This process is suitable for key processes such as component connection, clasping, and assembly after polishing of copper/stainless steel jewelry to ensure that the product meets the quality standards of the brand.
Brazing & Soldering is a key process for connecting metal parts in jewelry manufacturing, which directly affects the firmness and appearance integrity of the product. It is suitable for precision welding of copper and stainless steel jewelry to ensure that there is no cold solder joint, discoloration or solder overflow at the joint.
Forming & Shaping is a key process to ensure that the finished jewelry meets the designed size and is comfortable to wear. It is suitable for curvature adjustment, structural correction and surface optimization of copper and stainless steel jewelry to avoid the risk of breakage caused by deformation or stress concentration.
Mold Polishing & Finishing is a fine processing step in jewelry manufacturing. It is responsible for removing burrs, pores and joint lines after mold casting, improving surface finish and shape accuracy, and ensuring that the product meets design requirements and subsequent processing needs.
Grinding & Lapping is a key process for precision finishing of metal jewelry surfaces, eliminating tool marks, oxide layers and microscopic bumps, and providing a qualified base surface for subsequent polishing/electroplating. It is mainly used for batching, welding and structural interfaces of copper and stainless steel materials.
Copper plating is a process of electroplating a copper layer on the surface of a jewelry substrate (stainless steel/zinc alloy/silver). It is mainly used for:
O tipo de processo de impressão usa tecnologia de gravação a laser ou estampagem mecânica para formar uma marca clara e permanente na superfície da joia, atendendo às necessidades de logotipo de marca, marca de material metálico (como prata 925) e marca de certificação de conformidade. Este processo suporta gravação de alta precisão de 0,1 mm e é adequado para materiais comuns de joias, como cobre e aço inoxidável.
O polimento é usado para melhorar o acabamento e o brilho da superfície da joia, remover marcas de processamento (como marcas de torneamento, pontos de solda) e fazer com que o produto apresente diferentes efeitos, como espelho, fosco ou escovado. Este processo utiliza uma combinação de métodos mecânicos e químicos, adequado para cobre, aço inoxidável e outros metais, e atende aos padrões de qualidade de aparência dos mercados europeu e americano.
O processo de eletrodeposição forma uma camada protetora metálica na superfície da joia através de deposição eletrolítica, alcançando resistência à oxidação, resistência ao desgaste e personalização de cores (como platina, ouro rosa, preto fosco, etc.). Este processo está em conformidade com os padrões ambientais RoHS/REACH, é adequado para substratos de cobre e aço inoxidável, e pode atender aos rigorosos requisitos dos mercados europeu e americano para espessura de revestimento (0,5-5μm) e resistência à corrosão.
O processo de embalagem afeta diretamente a segurança do transporte do produto, o efeito de exibição da marca e a experiência de desembalagem do cliente. Oferecemos soluções de embalagem que atendem aos padrões ambientais europeus e americanos (papel certificado pelo FSC, materiais biodegradáveis), adaptando-se a diferentes tipos de produtos (peça única/conjunto), necessidades logísticas (transporte marítimo/aéreo à prova de umidade) e requisitos de personalização da marca (impressão de LOGO, inovação estrutural).
