Injection molding is one of the most common manufacturing methods for production parts; this also means an abundant list of material options for molding. These materials are each engineered and include general, common materials such as PC-ABS and specialty materials such as PEEK injection-mold.

There are many properties to consider when considering plastic injection molding materials. For many commodity, engineering, and performance-grade plastic materials, we have provided general features to help guide you to the best material for your application. We provide a 4-step guide for material selection.

 

1. Application – Begin with thorough product application understanding.

Where to use it?
How long must it last?
What environmental and mechanical conditions will expose the product?
What is your product's cosmetic or other performance characteristics?
What are your product's economic or cost constraints?

 

2. Material property

To be able to evaluate and select materials effectively, a general understanding of plastic material mechanical performance, chemical resistance, environmental requirements and technical standards used to measure performance is important. Moldplasticinjection provides an excellent understanding of these properties. Moldplasticinjection Properties.

 

3. Choose a material family

Once you understand the application and material properties well, you can begin to narrow your search to a family of plastic resins. In our Thermoplastic Material Guide, 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.

 

4. Specify equipment

Use the resource Moldplasticinjection Materials to pull manufacturers' material data sheets to review specific materials and match their performance to best suit your application. Additional performance can be achieved by compounding alloys, fillers, and additives. Moldplasticinjection engineers help our customers find cost-effective solutions with the right performance characteristics through the complex material selection process.

With every part you make, the material you select should be intentional. In this case, the utility, efficiency, and cost of the part should be carefully considered. It's important to understand that while some materials may be more popular than others, there's nothing like one-size-fits-all in manufacturing. Your material selection will always be directly related to your part's application at the end of the day.
