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...

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...

Project Background With the ongoing trend of high integration and modularization in new energy vehicle electrical systems, battery structural components play an increasingly critical role in vehicle platforms. As a key part for bearing, fixing, and protecting battery modules, the battery bracket requires high mechanical strength, dimensional stability, and environmental aging resistance, while mee...

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...

Introduction Polyphenylene Sulfide (PPS) is a semi-crystalline thermoplastic engineering polymer composed of alternating benzene rings and sulfur atoms in its molecular backbone, with the structural formula -[Ph-S]n- (Ph representing a phenyl ring). This unique combination of rigidity and stability has earned PPS the nickname “Plastic Gold.” PPS Long Glass Fiber Reinforced Four Core Properties of ...
