Injection Mold 1. If the mold cavity is poorly machined, with defects such as scratches, micro-pores, wear, or rough surfaces, it will affect the gloss of the plastic part. To address this, ensure precise machining of the mold to achieve a lower surface roughness for the cavity; if necessary, polish and chrome-plate the cavity. 2. If the cavity surface has oil stains, watermarks, or excessive mold...

1. Raw Material Quality or Batch Variations: Cause: Differences in raw materials (especially masterbatch) from different batches may lead to color mismatch, or unstable raw material quality can result in inconsistent product colors. Solution: Ensure Consistent Raw Materials: Choose reliable suppliers and perform color difference tests whenever a new batch of materials is used to ensure color consi...

When the deep black texture of carbon fiber intertwines with the luxurious glow of 24K gold on the Xiaomi SU7 Ultra, this "aesthetic violence" experiment in materials is pushing the boundaries of traditional automotive design. With 21 carbon fiber components, a total coverage area of 5.5 square meters, and an extreme focus on lightweight construction, Xiaomi applies its internet-driven "stacking l...

Overview of Carbon Fiber Reinforced Thermoplastic Composites Carbon fiber (CF) is produced by carbonizing organic fibers at high temperatures in an inert atmosphere. It is an excellent reinforcing material due to its high strength, high specific modulus, superior thermal properties, chemical stability, and damping, vibration reduction, and noise reduction characteristics. Compared with traditional...

In the injection molding process of glass fiber-reinforced materials, fiber floating is one of the most common surface defects. It appears as an uneven surface caused by exposed glass fibers on the part. This issue not only affects the visual appearance of the product but can also negatively impact secondary processes such as painting, coating, or electroplating. Today, we will take a deep dive in...

Project Background In high-performance bicycle design, the brake lever is not only a key control component but also directly impacts riding safety and handling precision. Traditional materials often fail to balance lightweight and strength, whereas long fiber reinforced thermoplastics offer outstanding rigidity, impact resistance, and fatigue durability, making them ideal alternatives to metals or...

In the field of polymer applications, shrinkage rate is a critical parameter that profoundly affects the dimensional accuracy, performance, and final application outcomes of polymer products. Whether in everyday plastic items or precision components used in advanced industrial sectors, understanding and controlling the shrinkage of polymer materials is essential to ensuring product quality and fun...

Application Background The bicycle bottle cage may look like a small accessory, but it plays an essential role. It needs to securely hold a bottle in place on rough roads, withstand outdoor exposure to rain, temperature shifts, and UV, while still allowing smooth insertion and removal. At the same time, riders expect it to be lightweight, durable, and visually aligned with the premium image of mod...
