Injection molding is one of the most common manufacturing methods for production parts; this also means that there is an abundant list of material options available for molding. These materials are each engineered and include general, common materials, like PC-ABS, as well as specialty materials like injection-molded PEEK.
When considering plastic injection molding
materials for your product there are many properties to consider. We have provided general characteristics for many of the commodity, engineering, and performance grade plastic materials to help guide you to the best material for your application. We are providing a 4 step guide to help with material selection.
1. Application – Begin with a thorough understanding of the product application.
Where it will be used?
How long it needs to last?
What environmental and mechanical conditions will the product be exposed?
What cosmetic or other performance characteristics do you desire for your product?
What economic or cost constraints do you have for your product?
2. Material Properties
To be able to effectively evaluate and select materials it is important to have a general understanding of plastic material mechanical performance, chemical resistance, environmental requirements and the technical standards used to measure performance. moldplasticinjection provides an excellent resource to understand these properties. moldplasticinjection Material Properties.
3. Select a material family
Once you have a good understanding of the application and material properties you can begin narrowing your search to a family of plastic resins. You can use the following charts to help narrow your search to a few materials or review summary descriptions of the most commonly specified materials in our Thermoplastic Material Guide below.
4. Specify Material
Use the moldplasticinjection Materials resource to pull up manufacturers’ material data sheets to review specific materials and match their performance to best suit your application. Additional performance can be achieved by compounding materials with alloys, fillers, and additives. The Engineers at moldplasticinjection help guide our customers through the complex material selection process to find cost-effective solutions with the right performance characteristics.
With every part you manufacture, the material you select should be intentional. In this instance, careful consideration should be given to the part’s utility, efficiency, and cost. It is important to understand that while certain materials may be more popular than others, there’s no such thing as one-size-fits-all in manufacturing. At the end of the day, your material selection will always be directly related to your part’s application.
