The production of Free Sample Graded Guard using TPU begins with high-precision plastic injection molding machines. TPU requires strict temperature, pressure, and injection speed control to achieve balanced flexibility, strong rebound, and long-lasting durability. Our advanced machines melt the TPU pellets evenly, then inject them into custom steel molds to form perfectly fitting graded guard frames for PSA, BGS, TAG, CCG, CCIC, PCG and CGC slabs. The technology ensures consistent thickness, accurate dimensions, and smooth edge finishing without deformation. Because TPU supports gradient coloring, the injection system includes color-metering valves for multi-color effects, producing vibrant and attractive protectors. Continuous production lines enable fast molding cycles, large output capacity, and stable quality. Each piece is checked for clarity, elasticity, and surface integrity before entering the dyeing or coloring process. With efficient TPU injection molding, we deliver durable, visually striking, and reliable Free Sample Graded Guard products. Right now we have 8 TPU plastic injection molding machines in our factory.

For silicone-based Free Sample Graded Guard, we use dedicated silicone injection molding machines designed for high-consistency LSR (liquid silicone rubber). LSR is fed through a precise mixing unit, combining base material and curing agent in exact ratios. This ensures consistent softness, elasticity, and superior shock absorption, ideal for protecting graded slabs. The machine injects silicone into the mold under controlled pressure to form guards with perfect stretchability and a tight, secure fit around PSA and BGS slabs. Silicone molding also prevents bubbles and uneven surfaces, guaranteeing a clean finish. Because silicone naturally resists heat, UV, and yellowing, it delivers long-term stability even with frequent handling. Our system supports solid-color and soft-tone gradient effects, producing visually appealing options. After molding, each silicone graded guard undergoes curing, trimming, and quality checks for surface smoothness and flexibility. Having 20 machines, this technology ensures stable output and premium-quality Free Sample Graded Guard products.

Coloring is one of the most important steps in producing attractive Free Sample Graded Guard products. Our dyeing machines are specially configured for TPU and silicone materials, allowing solid colors, smooth gradients, and complex multi-spot effects. TPU dyeing uses heat-penetration techniques where pigments bond deeply into the polymer, producing strong, vibrant colors that resist fading. This method enables beautiful dual- or triple-gradient finishes. For silicone, we use low-temperature absorption dyeing or surface-coating dyes depending on the style required. The machine rotates and heats materials evenly, ensuring consistent hues across every piece. When creating multi-gradient or spotted designs, controlled pigment injection technology produces unique combinations with artistic visual effects. Each batch is checked for color stability, fade resistance, and uniformity. This advanced dyeing system enables us to offer a wide range of stylish, customization color options for Free Sample Graded Guard, making each protector visually appealing and brand-ready.
