PFT, Shenzhen Abstract This study evaluates robotic polishing and chemical polishing techniques for jewelry finishing, focusing on labor cost efficiency and surface uniformity. A comparative analysis was conducted using a sample set of 120 silver and gold components. Robotic polishing employed a six-axis articulated arm with variable-speed polishing heads, while chemical polishing applied controlled acid baths under standardized conditions. Surface roughness measurements (Ra) were recorded using a contact profilometer, and labor costs were calculated based on process time and operator involvement. Results indicate that robotic polishing achieves consistent surface uniformity (Ra variation ≤5%) with higher initial equipment costs but lower per-piece labor expenses. Chemical polishing delivers comparable uniformity for simple geometries but exhibits greater variability on complex surfaces and incurs higher safety-related operational costs. Findings support the selection of robotic polishing for high-volume, intricate jewelry production, whereas chemical polishing remains suitable for simpler batch finishing with limited investment. 1. Introduction Jewelry finishing requires high precision to meet aesthetic and quality standards. Surface smoothness and uniformity directly influence product appeal, while labor costs significantly impact production economics. Robotic polishing and chemical polishing are two widely adopted finishing methods, yet their comparative performance regarding operational efficiency and surface consistency requires quantifiable assessment. This study provides a systematic evaluation to guide process selection in industrial jewelry manufacturing. 2. Research Methods 2.1 Design Approach A comparative experimental framework was established, focusing on labor input and surface roughness outcomes. The study incorporated repeatability and reproducibility by testing identical jewelry components under controlled conditions. 2.2 Data Sources Data were collected from a Shenzhen-based jewelry manufacturing facility over a four-week period. Component types included 60 silver pendants and 60 gold rings, representing a range of surface geometries. 2.3 Experimental Tools and Models Robotic Polishing: Six-axis robotic arm (KUKA KR6) equipped with variable-speed polishing heads, programmed for automated path control. Chemical Polishing: Standardized acid bath setup with temperature control (25 ± 1°C) and timed immersion protocols. Measurement Tools: Contact profilometer (Mitutoyo SJ-410) for Ra measurements, labor cost calculated from operator time logs. All procedures were documented to ensure reproducibility, including robot path scripts, chemical bath compositions, and safety protocols. 3. Results and Analysis 3.1 Surface Roughness Comparison Table 1. Surface Roughness (Ra) Comparison Method Simple Geometry Ra (µm) Complex Geometry Ra (µm) Variation (%) Robotic Polishing 0.12 0.15 ≤5% Chemical Polishing 0.14 0.22 15% Robotic polishing demonstrated lower variability across both simple and complex geometries, ensuring uniform finishing. Chemical polishing showed higher Ra variation, particularly on complex shapes. 3.2 Labor Cost Evaluation Figure 1. Labor Cost per Piece Labor cost analysis indicated robotic polishing reduced operator involvement by 60%, whereas chemical polishing required continuous monitoring for safety and quality control. 4. Discussion 4.1 Mechanistic Interpretation The higher uniformity in robotic polishing is attributed to precise tool-path control and consistent contact force. Chemical polishing uniformity is geometry-dependent, limited by differential acid exposure in recessed areas. 4.2 Limitations Robotic setup requires higher initial investment and maintenance. Chemical polishing poses environmental and safety management challenges. 4.3 Practical Implications For high-volume production of intricately designed jewelry, robotic polishing optimizes both surface quality and labor efficiency. Chemical polishing remains applicable for simpler, low-volume batches with cost constraints. 5. Conclusion Robotic polishing provides superior surface uniformity and lower per-piece labor costs, making it suitable for complex, high-volume jewelry finishing. Chemical polishing is adequate for simple geometries but entails higher labor monitoring and safety overhead. Future research may explore hybrid approaches combining robotic pre-polishing with chemical finishing for optimized efficiency and surface aesthetics.

PFT Shenzhen Date: 2025 Introduction: Choosing the Right Manufacturing Method for Shape-Shifting Medical Devices Medical devices that adapt their shape dynamically are becoming crucial in minimally invasive surgery, drug delivery systems, and wearable health tech. Two leading manufacturing approaches dominate this space: 4D printing and silicone molding. Understanding the differences in activation precision, durability, and scalability is essential for engineers, procurement teams, and R&D specialists. This guide breaks down practical insights, supported by real-world experiments and comparative data. What is 4D Printing in Medical Devices? 4D printing is an extension of 3D printing where the printed structure changes shape over time in response to external stimuli, such as temperature, moisture, or pH levels. Key advantages in medical applications: High activation precision: Shapes can shift within 0.1–0.3 mm tolerance. Customizable material properties: Hydrogel or SMP (Shape Memory Polymer) layers allow targeted responsiveness. Rapid prototyping: Design iterations can be tested without creating molds. Real-world example: In our Shenzhen lab, we produced a shape-shifting stent prototype using SMP-based 4D printing. The device reliably expanded from 2 mm to 6 mm in diameter within 15 seconds at body temperature, demonstrating high repeatability across 50 cycles. What is Silicone Molding in Medical Devices? Silicone molding involves creating a mold of the desired shape and casting silicone elastomers that can deform under stress but return to their original form. Key advantages: Durable under mechanical stress: Can withstand over 1 million bending cycles. Biocompatible and chemically inert: Ideal for long-term implantation or contact with bodily fluids. Cost-effective for mass production: Once molds are made, hundreds of devices can be produced with consistent quality. Practical insight: A shape-shifting valve made via silicone molding in our trials showed minor dimensional drift (±0.5 mm) after 100,000 cycles—excellent for long-term wearable devices but lower in activation precision compared to 4D printing. Side-by-Side Comparison: Activation Precision & Durability Feature 4D Printing Silicone Molding Activation Precision ±0.1–0.3 mm ±0.5–1.0 mm Durability (cycles) 50–200 typical 100,000–1,000,000 Biocompatibility Medium (depends on polymer) High Customization High (easy design iteration) Medium (requires new mold) Scalability Low to medium High Lead Time 1–3 days 1–2 weeks per mold When to Choose 4D Printing Rapid prototyping: Ideal for testing shape-shifting behaviors quickly. High precision applications: Microneedles, micro-valves, or devices needing sub-millimeter shape control. Small batch production: Startups or labs needing iterative designs. Tips from experience: Always calibrate printing temperature and layer thickness; even a 2°C deviation can reduce activation precision by 20%. Use SMPs with fast recovery rates for devices requiring instant deployment. When to Choose Silicone Molding Mass production: Hundreds or thousands of identical devices needed. High durability requirements: Long-term implants or wearable devices. Biocompatibility critical: FDA-approved silicone grades ensure safety. Practical insight: Optimize mold release agents to prevent micro-bubbles, which can reduce activation consistency. Use multi-cavity molds for batch consistency and shorter production cycles. Hybrid Approaches: Combining 4D Printing and Silicone Molding In some medical device designs, hybrid manufacturing maximizes both precision and durability: 4D-printed inserts embedded within silicone molds can achieve micro-scale shape shifts while maintaining bulk durability. Case study: A micro-valve for insulin delivery achieved ±0.15 mm activation precision and over 200,000 cycles durability by combining 4D-printed SMP cores with molded silicone bodies.

The Scenario You Don’t Want to Face  The spindle winds down with a metallic whine and then a hollow click—then silence fills the shop. I’m standing there, hand on the control pendant, eyes fixed on the probe readout, waiting. The probe reports a number. The controller accepts it. The part is wrong. Why did that happen? It’s maddening!  This scene happens more often than you’d like. One misread probe can ruin an entire batch, delay deliveries, and cost thousands. For procurement professionals, this isn’t just a technical detail—it directly impacts budgets and schedules. So, how do we stop it? Why Probes Lie  Most false readings are caused by poor calibration—the process of aligning a sensor’s output to a known reference. Think of it as verifying your kitchen scale with a 5 lb dumbbell. Examples of calibration tools: Gauge Block: A hardened steel block ground to an exact thickness (e.g., 10.000 mm), used to check probe accuracy. Touch the probe to the block, compare the reading, and adjust the offset if necessary. Tool Setter: A dedicated device for measuring tool length and diameter automatically. We place the cutter into a tool setter to confirm diameter before critical runs.  Skip these checks, and offsets—the numeric corrections the CNC applies to compensate for tool and holder length—start drifting. Cutters dig too deep or leave material behind. Say goodbye to precision!
