Why Are Resin, Plastic & Acrylic Jewelry So Popular_ Materials, Production Process And Care.pptx

Hey jewelry fans! Ever wondered why resin, plastic, and acrylic jewelry are everywhere these days? Well, it’s all about the materials and how they’re made. Resin is like magic goo that turns solid when it cools down. It’s super versatile, cheap, and can be made into anything from bangles to hairpins. The best part? It looks super realistic—like glass or jade!
Plastic jewelry is another game-changer. It’s made using molds and can be shaped into anything you can imagine. There are tons of ways to make it, from injection molding (perfect for complex shapes) to thermoforming (great for big, hollow pieces). And acrylic jewelry? It’s like glass but lighter and tougher. It’s easy to work with, comes in vibrant colors, and can be cut, engraved, or even laser-processed.
But making these pieces isn’t always smooth sailing. Resin can have air bubbles or deform if not handled right, and acrylic can crack under stress. That’s why skilled craftsmen are key! With the right care, these pieces can last forever. Just avoid scratches, keep them dry, and they’ll shine like new.
So, whether you’re a jewelry store, designer, or even a celebrity looking for custom pieces, resin, plastic, and acrylic jewelry are your go-to. They’re trendy, affordable, and perfect for any style!

9. Common Problems and Solutions in the Production of Resin Raw Blank Problem Causes Solutions Air Holes - Complex structures or small injection ports without vents. - High vacuum resistance in dead corners. - Use thinner resin or reduce filler concentration. - Reduce red/white materials to extend curing time. - Ensure vacuum pump reaches -0.1MPa. - Add venting designs in molds for complex structures. Oil/Pin holes - Oils and thinners in slurry gather or disperse. - Stratification in cooler seasons. - Use higher-concentration resin and reduce filler. - Minimize oil addition (below 5‰). - Ensure fillers like stone powder are dry. - Add oils 15-20 minutes before use and mix thoroughly. Stone Powder After Alkali Soaking - Surface resin not fully cured, eroded by alkali. - Increase curing agent (1.5%-2.5%) or add slow-drying agents. - Control alkali concentration (pH 11-12) and soaking time. - Avoid low-concentration resin. Deformation - Uneven internal stress from resin shrinkage. - Use resin with lower shrinkage rate. - Reduce red/white materials and stack products for curing. - Use thermal insulation and accelerated curing (30-80℃). - Increase filler or reinforcement. Cracking - Slow post-curing or improper demolding. - Internal stress from resin shrinkage and thermal expansion. - Use higher-concentration resin. - Use slower-curing resin and add reinforcements (e.g., wires, fibers). - Avoid sudden dimensional changes in product design. - Add 10% soft resin for toughness. Stratification - Poor cross-linking with styrene monomer. - Excessive oils or damp fillers. - Avoid low-viscosity resin and excessive diluents. - Control oil addition (below 5‰) and mix thoroughly. - Use dry stone powder and avoid prolonged slurry storage. Watermarks - High humidity or damp fillers. - Poor-quality curing agents or accelerators. - Low temperatures or damp molds. - Use high-quality resin and dry fillers. - Ensure sufficient curing agent and proper resin temperature (30-40℃). - Dry new molds before use, especially in humid conditions.

13. Plastic Jewelry Production Process Category Subcategory Description One-Time Molding Injection Molding - Uses molds (metal, wood, fiberglass, gypsum) to shape thermoplastic and thermosetting plastics. - Produces complex shapes, precise dimensions, and inserts. Extrusion Molding - Forms continuous profiles (pipes, sheets, films) by melting and shaping plastic through a die. - High productivity, low cost, and suitable for most thermoplastics. Compression Molding - Uses heat and pressure to shape thermosetting plastics in molds (molding or laminating). - Simple equipment but long cycle times and low efficiency. Casting and Forming - Includes static casting, centrifugal casting, cast film casting, and rotational molding. - Produces large, hollow, or film products. Secondary Molding Blow Molding - Uses gas pressure to expand preforms into hollow products (injection or extrusion blow molding). - Common materials: polyethylene, polypropylene, PVC, polyester. Thermoforming - Heats thermoplastic sheets to soften and shape them using molds or differential pressure. - Includes compression and differential pressure (vacuum/air pressure) molding. Bi-axial Stretching - Reorients thermoplastic films or sheets above glass transition temperature for improved strength. Secondary Processing Machining - Cutting, drilling, milling, and laser processing (cutting, drilling, engraving, welding). Connection Processing - Mechanical (threads, rivets), hot melt (welding), and adhesive bonding. Finishing Processing - Mechanical finishing (grinding, polishing), coating, painting, printing, and metal plating.

15. Introduction to Acrylic Materials High transparency (92% light transmittance) and excellent surface hardness and gloss. Lightweight, with a density half that of glass and 43% of aluminum. Outstanding weather resistance, UV stability, and acid-base resistance. High mechanical strength, toughness, and thermal shock resistance (7-18x stronger than glass). Excellent processing performance, suitable for thermal and mechanical methods like cutting, engraving, and laser processing. Good printability and surface decoration effects with vibrant colors. Easy to repair, maintain, and clean. Advantages of Acrylic: Prone to stress cracking due to room temperature creep under load. Hygroscopic, requiring drying before processing. Low surface hardness, making it susceptible to scratching. Disadvantages of Acrylic:
