Vertically Integrated Production
Haosen integrates multiple forming processes to support different structures, designs, and cost requirements, including stamping for efficient production, laser cutting for clean and accurate shapes, lost wax casting for detailed 3D designs (through a long-term partner foundry in which we hold an equity stake), and lathe machining for tight-tolerance components. This allows us to optimize the right manufacturing route for each product, reduce dependency on outsourcing, and ensure consistent quality and lead time from prototype development to scale-up production.
Surface Finishing Solutions
Haosen provides end-to-end surface finishing options to meet different style demands and durability standards, including enamel for vibrant color effects, PVD plating for premium wear resistance, and electroplating for stable and cost-effective finishes. With controlled process parameters and strict QC inspection, we minimize common issues such as uneven coating, weak adhesion, and color variation across batches—helping your products maintain an appearance and consistent quality in mass production.
Metal Material & Plating Analysis
Our jewelry factory utilizes professional EDXRF Spectrometers (Thick800A) for non-destructive material analysis on every batch. We precisely monitor PVD plating thickness to guarantee superior wear resistance and finish longevity. This rigorous screening ensures Lead (Pb), Cadmium (Cd), and Nickel (Ni) levels are 100% compliant with REACH and California Proposition 65 standards.
Salt Spray Test
We perform jewelry’s 72-hour accelerated testing in a Salt Spray Chamber. This deep-level oxidation test verifies the durability of our jewelry finishes, ensuring maintains its original metallic luster even under harsh coastal conditions.
Constant Temperature Test
Simulates extreme global climates to verify physical stability. This quality check prevents fading, rusting, or structural damage caused by temperature fluctuations, providing consistent reliability for international markets.
Logistics Reliability Test
We use specialized Vibration Testers to replicate the rigors of global shipping. Our protocol simulates vehicle speeds of 25~40km/h with a precise vibration frequency of 100-300rpm, ensuring the structural integrity of both the jewelry and its packaging. This high-intensity simulation guarantees that Haosen orders withstand long-haul transit and arrive in pristine condition.
