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 aerospace industry is undergoing a lightweight revolution powered by specialty engineering plastics. Imported high-performance materials like PEEK, PI, and PPS, renowned for their exceptional lightness, extreme environment resistance, high strength, and flame retardancy, are increasingly replacing traditional metals in cabin interiors, engine components, avionics, and UAV structures. Advancements such as composite reinforcement and 3D printing compatibility are further expanding their applications. Amidst market growth and sustainability demands, these plastics have become key enablers for efficient and green aerospace manufacturing, with a promising future.

From Feb 9-10, our team escaped to Chongming Island for a spring retreat. Day 1 featured our year-end review meeting, followed by team games and a warm dinner. Day 2 brought creative crafting sessions and collaborative challenges. Though brief, these two days refreshed us amidst nature and strengthened our bonds. We return energized and united—ready to embrace the exciting journey of 2026 together!

This article delves into the complete transformation process of engineering plastic pellets from raw material to precision parts. It systematically introduces the three fundamental processes of injection molding, extrusion, and blow molding, extending to specialized techniques like thermoforming and rotational molding.

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.
