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.

Many people choose soft polymers because they are certain the softer materials are more flexible. In fact, some of the softest materials are not as flexible as many people assume. You are likely to find a hard injection mold plastic that is flexible than soft polymers like nylon. Prior to selecting a molding element, consider the weight. You can decide to choose light or heavyweight materials based on company preferences. Keep in mind, the weight of finished products is determined by the density of plastic molding.

Cost is a major concern for buyers in the market for injection molding plastics. However, pricing should not be the sole determinant when it comes to buying polymers. Your top priority should be the product application. Do not compromise quality by selecting a cheaper material that is not designed for the desired application.

Identifying a material worth company investment is not as complicated as buyers think. All you have to do is determine the purpose of the commodity. Understanding the use of an application within set time frames helps in determining the right plastics for molding. Decide how much you are willing to spend on an injection mold material and the modifications you want. Other factors include environmental aspects and performance.

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.
