Selecting The Right Materials For Your Prototype Plastic Parts

Selecting the Right Materials for Your Prototype Plastic Parts

Everyone understands the need for proper material selection. Choosing the right material is very important if you are going to optimize the functionality, strength and even profitability of your product. 
When producing a plastic part, you will be confronted with a lot of resins to choose from. You will need to consider a number of factors from temperature to elasticity or end-use. Here are a few things to keep in mind when making your choice. 

Purpose and end-use requirements 
Consider the functionality and exact purpose of your product. Automobiles will require plastic injection molding parts that are light to contribute to fuel efficiency, while medical purpose equipment will demand lube-free resins that do not leach or contaminate samples. 

Cost optimization 
In order to be profitable, you will need to select the proper resin that can match and surpass the cost of production of your part. Do not go after high-performance resins when standard options like ABS will suffice for your performance needs. 

Strength and Durability 
Knowing the type of load or force that your end-use part may be dealing with will be of great importance. You should also anticipate the misuses that may arise and what type of durability each resin brings. 
Properties such as elasticity, fatigue limits, ease of wear and tear and friction. As heat plays an important part in deforming plastics, consider how you resins react to certain extremes and lows and whether they will perform optimally at the temperatures in which they are likely to be exposed. 

Appearance and Finishing 
Talk to your manufacturer or material expert before picking any type of resins for their appearance properties. Finishing plays an important role in consumer purchase choices. If your product demands a specific colour or a combination of colours to attain the desired property, ensure that you pick resins worthy of those combination. 
Colours may be important for pure visual attractiveness or for reflection, shading or deflection of light waves. 

Environmental conditions and factors
What conditions or factors are your product going to be deployed in? Do they require certain specific characteristics to perform in these conditions? Attending to these environmental queries will aid the correct selection of materials.
You will find that certain resins have better water-shielding capacity, chemical resistance and flame retarding capacities than others, all of which may affect the usability or efficiency of your part.
