Injection molding processes remain among the most influential manufacturing methods in modern plastics engineering. Despite decades of industrial evolution, these processes continue to serve as the backbone of mass production for plastic components across medical, automotive, construction, consumer goods, and industrial applications. From a materials engineering perspective, injection molding processes are best understood not only through machine capabilities or mold design, but through the way polymers respond to heat, pressure, shear, and cooling under real production conditions. Subtle differences in material behavior during processing often determine whether a process is stable, repeatable, and economically viable at scale. This article is

Outdoor environments place significant stress on materials, with ultraviolet (UV) radiation being one of the primary causes of degradation. Prolonged UV exposure can lead to discoloration, reduced mechanical strength, and shortened product lifespan, especially in plastic applications. For engineers, manufacturers, UV-resistant plastics play a critical role in ensuring long-term performance and reliability in outdoor use. By integrating suitable UV stabilizers, these materials help maintain both functionality and appearance over time. Read the full technical insight on UV resistant plastics in the TLD Vietnam blog. Understanding UV Resistant Plastics UV-resistant plastics are materials that have been specifically formulated or treated to

Polymer films are extensively applied in medical, agricultural, packaging, and industrial fields, where mechanical performance has a direct impact on functionality, reliability, and service life. Among the key mechanical properties, stiffness is particularly critical, as it influences resistance to deformation, handling characteristics, and structural stability during use. Film stiffness does not arise from a single parameter but from the interaction of multiple factors. Material composition, molecular structure, processing conditions, and environmental exposure collectively determine the final stiffness profile of a polymer film. A clear and systematic understanding of these influences is essential for engineers, product developers, and procurement professionals when

Injection molding is a process where molten material is injected into a mold to create a precise shape. While plastics are most common, metals and rubbers can also be used. Choosing the right material is critical, as it directly affects the product’s strength, flexibility, durability, and overall performance. Materials differ in melting points, shrink rates, and other properties, which can impact molding success.
