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.

The process of buying molding materials should be less stressful. Consider learning the variation of properties each resin holds. Start by evaluating the hardness of different materials that are commonly used for the production of different commodities. Hardness is measured in units between zero to one hundred and classified as type A and type D depending on hardness level. Invest time to learn the mode of measuring plastic hardness to have an insight of what to expect when you select a specific level of hardness to produce an application.

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.

It is common to see buyers select cheap molding plastics with the intention of saving extra money. However, the cheapest polymers may not produce quality applications in the long run. This means you should not compromise the quality of the application by purchasing low-cost polymers. Buy materials that fit application specifications to ensure the final products function according to set requirements.

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.

Consider the material property to make sure it fits the product application. Properties vary in many ways depending on material performance. Make use of measurement charts to identify materials that suit your flexibility, hardness and weight requirements.

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.

The final step is to match material property with application functionality. This can be done by revising charts provided by injection molding plastic suppliers. Once you have identified the right molding element, it is important to decide the kind of modifications that work best to enhance performance. It is easy to improve performance by applying fillers, alloys or additives.
