Injection molding often encounters burn marks, a critical defect that severely impacts product appearance and quality. This article deeply analyzes the root causes of burn marks and proposes systematic countermeasures.

High-Performance PPS (Polyphenylene Sulfide) Film with Broad Application Prospects PPS (Polyphenylene Sulfide) is a high-performance specialty engineering plastic, classified as a high molecular weight crystalline polymer with a density of 1.35 g/cm³. It features a linear molecular structure formed by alternating benzene rings and sulfur atoms. The combination of rigid benzene rings and flexible thioether linkages endows PPS with outstanding properties, including excellent heat resistance, flame retardancy, chemical corrosion resistance, mechanical strength, and dimensional stability.

The J10C achieves a transformative advancement in China’s aviation sector through five core material innovations: carbon fiber composites for weight reduction, stealth coatings for RCS suppression, ultrahightemperature ceramics for extreme environments, titanium/aluminum alloys for structural reinforcement, and advanced resinbased materials for electronic warfare. These breakthroughs propel China’s aviation industry from "follower" to "leader," laying the technical foundation for subsequent models like the J20 and J35.

Polyoxymethylene (POM) has become a star material for precision gears due to its metal-like rigidity, excellent fatigue resistance, low friction coefficient, and outstanding dimensional stability. Beyond solving core challenges like wear and noise reduction, it enables innovation in office equipment, automotive components, and micro-transmission systems through lightweighting, design integration, and oil-free operation. Shanghai Weisa Plastic Technology collaborates with industry leaders like BASF and SABIC to provide comprehensive POM solutions—from high-purity Ultraform® to self-lubricating LEXAN™—helping achieve more reliable, efficient, and cost-effective precision drive designs.

At the 2026 CCTV Spring Festival Gala, robots evolved from dancing Yangge to executing backflips—more agile, more dynamic. Behind this leap is a "skeletal evolution" driven by specialty engineering plastics. PEEK is 70% lighter than steel, offering high strength, self-lubrication, and micron-level precision for flexible, accurate joints. PPS provides heat and chemical resistance, ensuring electrical system safety. "Replacing steel with plastics" solves range anxiety and enables cost-effective mass production through injection molding. From walking to running and jumping, every step in humanoid robot evolution relies on breakthrough materials.

The Middle East conflict has disrupted Strait of Hormuz shipping, posing major challenges for imported engineering plastics including supply shortages, price surges, and extended lead times. We recommend extending procurement cycles, diversifying sources, and partnering with a professional trading company to mitigate risks and ensure stable supply.
