TPU Material — A Preferred Elastomer from the plastic injection molding manufacturer Perspective
TPU Material Definition and Basic Concepts
Thermoplastic polyurethane (TPU) is a class of high-performance polymers that combines the properties of plastic and rubber. It softens and flows under heat and regains elasticity upon cooling. TPU features excellent wear resistance, oil resistance, weather resistance, and elasticity, making it widely used across various industries. When selecting suitable plastics or elastomers, engineers often conduct an injection molding plastics comparison, evaluating TPU against other materials (such as PP, PE, PA) in terms of processing behavior, mechanical performance, and cost, highlighting its unique advantages.

What is PPO? — Its Widespread Applications in medical injection molding and plastic injection components
PPO (Polyphenylene Oxide) is a high-performance engineering plastic known for its excellent thermal stability, electrical insulation, and dimensional stability. In the production of medical injection molding, automotive injection, injection moulding large parts, and various plastic injection components, PPO, with its outstanding overall performance, meets the stringent requirements of high temperature, high strength, and high precision in medical, automotive, and industrial fields. Below, we will provide a comprehensive analysis of PPO material's definition, properties, and typical applications, combining the original descriptions with specific data.

Silicone Injection Molding is an advanced process that combines the characteristics of thermoset elastomers with high-precision injection technology. Through the injection moulding process step by step, either liquid or solid silicone is injected into molds under high pressure and temperature, then rapidly cured. This method is widely used in plastic injection components and medical device injection molding. Silicone offers the elasticity of rubber and the processing efficiency of plastic, ensuring short molding cycles, high dimensional precision, and excellent weather resistance and biocompatibility. It is ideal for manufacturing baby pacifiers, sealing rings, electronic buttons, and more.

In modern manufacturing, plastic injection mold design is the critical process for achieving efficient, precise, and repeatable production. Through well-considered mold structure and process design, defects can be minimized, productivity increased, and manufacturing costs reduced.

This guide is intended to provide readers with a comprehensive comparison of six commonly used thermoplastic materials for injection molding: PP, PE, PET, PA, PC, and PS. From definitions, mechanical properties, and application scenarios to the impact on finished product performance, we aim to help decision-makers across industrial molding corporation, injection mold inc, moulding maker, and other sectors select the optimal material. Real-world use cases in custom plastic parts, plastic parts manufacturing, medical device injection molding, and automotive injection are included to support informed, practical decisions.

In injection molding projects, the choice of material directly determines product performance, durability, safety, and cost.

Overmolding, also known as multi-shot molding or soft-touch molding, is a high-performance, integrated injection molding process used to combine two or more different plastic materials into a single, functional component. As multi-material technology and mold-making capabilities have evolved, Overmolding has been widely applied across custom plastic parts, medical device molding, plastic parts manufacturing, and medical plastic molding, becoming a key technique in precision manufacturing.

In the modern plastics processing industry, large part injection molding refers to the injection molding of components that exceed typical size or weight ranges. Compared to small or medium-sized plastic parts, large part injection molding requires higher standards for machine tonnage, mold structure, and injection process control.

This technique is widely used in industries such as automotive, medical, aerospace, and construction to produce large housings, structural parts, and functional components. By optimizing process parameters and mold design, large part injection molding ensures dimensional accuracy and mechanical performance, meeting the demands of high-end applications.
