CAD modeling has revolutionized product design processes, enhancing efficiency, precision, and innovation. This article delves into the world of CAD modeling, exploring its types, evolution, applications, and transformative impact on product design, particularly in plastics and injection molding.

What is CAD Modeling?

Computer-Aided Design (CAD) modeling refers to the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD models are digital representations of physical objects, enabling designers to visualize and manipulate them in a virtual environment. In the context of modern product design and manufacturing, CAD modeling plays a pivotal role by enhancing visualization, improving accuracy, reducing errors, and streamlining the design process.

In the plastic injection molding industry, CAD modeling is crucial. It allows for the precise design of molds and plastic parts, facilitating innovation in custom plastic part design. By simulating the injection molding process, CAD modeling helps identify potential issues before production, saving time and resources.

Types of CAD Modeling

Understanding the different types of CAD modeling is crucial for selecting the appropriate tools and techniques for specific design needs. Here are the primary types of CAD modeling:
