How To Select Injection Mold Plastics

By John Green


Production companies rely on injections molding plastic materials to manufacture high-quality products. However, with a variety of choices to choose from, selecting the right molding components can be challenging. Most production companies tend to choose the wrong products because they are unaware of what to look for in injection mold plastics. Here is a list of qualities to consider and tips to purchase products suitable for a specific application.

Plastic molding materials vary in many ways depending on the category they are placed in. Some of the main properties to look at include; flexibility, hardness, cost, and weight. Material toughness varies from one material category to another. In order to measure resistance or hardness to indentation, you need to use a measuring device to determine whether a material types A or type D. The scale is designed to measure soft and hard materials from zero to one hundred.

People make assumptions that the hardest materials cannot bend to a specific point like soft materials. It may sound odd, but there are some hard molding materials with flexibility features, while soft ones break when a heavy load is loaded due to lack of flexibility. Apart from flexibility, make sure to measure the weight of desired materials to determine if the density guarantees quality products after molding.

Although cost is an important property to look at when choosing injection molding plastic, it should not be the main determinant. Take into consideration the product application before making any decision. This step helps you select a material that meets your production needs as well as budget.

Now that you are aware of the different properties molding materials possess, it is time to purchase the right materials. First, decide what type of application you wish to create using a specific polymer. This step helps you choose a material that suits the usages of the application for a specified period of time. Consider the environment the application will be exposed to, performance quality characteristics and cosmetics you plan to fit in the application. You should also determine a budget to guide you in selecting quality materials that fit your needs.

Hardness, the flexibility, and weight are key aspects that determine plastic molding performance. That is why buyers need to decide the usage of applications beforehand. This step enables buyers to choose molding elements that blend well with commodity performance.

Specify injection molding plastic family before investing on any materials available in the market. Plastic families vary in weight flexibility and hardness factors that determine performance. Take a look at material specifications to determine the right one for product applications. Some common material families are polycarbonate, polyamide also referred to as nylon, polyethylene, Acrylonitrile Butadiene Styrene, and polypropylene.

Understand specific material properties and match their performance with the help of a manufacturer material chart or sheet. Select a material that is designed to perform a specific function depending on your application. Remember, the performance of injection molding materials can be improved with fillers and alloys. With these helpful tips, you can make the right choices within a short duration.
