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.

In September 2025, the Shanghai Visa Plastics team embarked on a four-day trip to western Sichuan. They tempered the team spirit amid the mountains and rivers of Jiuzhaigou and Huanglong, and gained innovative inspiration from the ancient Shu civilization at Sanxingdui. They supported each other during the plateau hike, practicing the corporate belief of "win-win cooperation"; facing the thousand-year-old cultural relics, the craftsmanship spirit and technological innovation resonated across time. This was not only an enhancement of team cohesion but also an in-depth awakening of professional craftsmanship. The Visa people will carry this harvest and work together to open a new chapter in plastic technology with greater enthusiasm and more solid collaboration.

Daicel Group announces the full integration of its subsidiary Polyplastics' engineering plastics business, effective April 2026. This restructuring aims to create a more competitive high-performance materials platform, combining Polyplastics' leading products and technologies in POM, LCP, and other fields. Through unified management and strategic synergy, Daicel will optimize global operations, enhance innovation capabilities, and provide more comprehensive and efficient solutions for automotive, electronics, healthcare, and other industries, strengthening its position as a global leader in engineering plastics.

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.

PPA (Polyphthalamide), a high-performance specialty engineering plastic known as the "special steel" of plastics, is quietly reshaping manufacturing. With exceptional heat resistance (long-term use at 150-180°C), high strength/rigidity, and excellent chemical resistance, PPA is an ideal material replacing traditional plastics and metals. It plays a key role in automotive electrification (e.g., charging components), electronics miniaturization (e.g., 5G antennas), and industrial extreme environments, driving industries towards lighter weight and higher performance.

PFAS, known as “forever chemicals,” are a large group of fluorinated substances with extremely stable carbon-fluorine bonds that resist degradation in the environment and pose health risks. In engineering plastics, fluoropolymers such as PTFE, PFA, and PVDF are used either as base materials or processing aids to provide heat resistance, low friction, and non-stick properties. Due to tightening regulations by the EU, U.S., and China, customers now demand PFAS test reports to verify compliance. This requirement helps avoid customs detention, meet brand owners’ sustainability mandates, and prevent costly lawsuits. Without a valid report, products risk being excluded from supply chains. The industry is rapidly moving toward PFAS-free alternatives. A certified test report has become a mandatory pass for global trade in engineering plastics.
