Types of Plastics and Materials for Injection Molding
Practical design guidance from Texas Injection Molding engineers for developing robust, manufacturable plastic parts.
How to Choose the Right Injection Molding Material
Material selection starts with understanding how your part will perform, where it will be used, and what it must withstand.
01 — Application
Start by defining how the part will be used and what it needs to accomplish.
e.g. end use, environment, regulatory requirements
02 — Material Properties
Evaluate the required properties to support the application.
e.g. strength, heat resistance, chemical resistance, dimensional stability
03 — Select a Material Family
Use your requirements to narrow the options to the right family of plastics.
e.g. commodity, engineering, or high-performance
04— Specify Material
Compare specific resin grades and manufacturers to find the best fit.
e.g. grade, additives, color, regulatory compliance
