The shrinkage rate of plastic reflects the degree of dimensional reduction in a plastic part after it is removed from the mold and cooled. Factors affecting plastic shrinkage include the type of plastic, molding conditions, and mold structure. Different plastics exhibit varying shrinkage rates. Additionally, the shrinkage rate is significantly influenced by the part's shape, complexity of internal structure, and the presence of inserts.

In modern industry and everyday life, friction and wear of mechanical components consume energy, shorten equipment life, and can also cause annoying noise. How can you achieve smoother gears, more durable bearings, and quieter equipment? The application of self-lubricating plastic materials provides an innovative solution to this dilemma. This material not only retains the advantages of traditional plastics, such as light weight and easy molding, but also "self-lubrication", becoming an effective means for mechanical engineers to solve friction and wear problems.

Engineering plastics with exceptional heat resistance maintain robust mechanical properties in high-temperature environments, making them indispensable for demanding applications. Beyond widely known high-temperature nylons, five other categories of heat-resistant engineering plastics play critical roles across industries.

This article systematically decodes nine key performance indicators of engineering plastics, covering basic properties, mechanical strength, surface and electrical characteristics, temperature/weather resistance, chemical stability, and cost economics. By comparing the performance differences and application scenarios of various plastic materials, it reveals the scientific principles and trade-off wisdom in material selection. The text emphasizes that in this era where materials define products, a deep understanding of plastic properties is fundamental for achieving product innovation and enhancing performance and value. It also looks forward to development trends toward high performance, functionality, and environmental sustainability.

PES is a high-performance specialty engineering plastic. Thanks to its unique molecular structure, it maintains excellent mechanical strength and dimensional stability even under long-term high-temperature environments (above 180°C). It also offers transparency, hydrolysis resistance, flame retardancy, and is BPA-free. Widely used in medical devices (e.g., reusable sterilizable instruments), electronics (high-temperature connectors), and automotive components, PES is a critical material for high-end industrial and technological products.

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.
