Selecting the right material is one of the most important decisions you will make when planning your injection molded parts. The material you choose will determine the part’s strength, flexibility, temperature resistance, and cost, impacting your product’s performance and success in the market. Whether you are working with an injection molding company for a new product launch or scaling up your existing product, understanding your material options helps you make informed decisions and avoid costly mistakes. Understand Your Application Requirements The first step in choosing the right material is to analyze the requirements of your product: Mechanical Properties: Does your part need to be rigid or flexible? Should it withstand heavy loads or impacts? Thermal Properties: Will the part be exposed to high or low temperatures? Chemical Resistance: Will the part come into contact with chemicals, oils, or water? Appearance: Do you need a specific color or surface fini...
Controlling the way molten plastic fills and cools in a plastic injection mold to form a part is an evolving science. Youthful companies are injecting new energy into this industry all the time, to improve the quality and accuracy of molding that in turn will enhance the usefulness of parts being made. Dividing the part to be built into basic groups helps minimize molding problems and improve accuracy.
Versatile Applications
Plastic injection moldingare used for making all kinds of components for everything from aerospace to consumer electronics. The process can produce parts with holes, springs, threads, hinges and other finely defined uses. Sophisticated tooling can be rendered accurately to 100th of a millimeter. Parts can be as simple as a toothbrush or set of nails or as complex as a lipstick or laparoscopic surgical instrument.
Flawless Products
Whether flexible or rigid, small or large, objects made through a plastic injection mold are generally flawless. The products can also be textured, polished, plated or colored. The range and capability of the process is matchless. Customized machines of all sizes Plastic Manufacturing in the United States multiple products that we use on a daily basis and parts for use in specialized applications.

Finely tuned measuring devices exist in the process, to form for example, a foam cup and its tightly-fitting plastic lid. Lego is another example of a precision product available in many colors, shapes and sizes and made purely with plastic injection mold. Today there is outstanding software that allows precise measurement of 3D objects. This technology is widely used to measure surface and form profiles for enhanced accuracy.
Measurement Devices
Dimensions of components need to be precise to prevent faults from occurring when the part is in use. For example micro gear drives used extensively in motor vehicles and household appliances can be troublesome if not accurately made. Automatically identifying potential flaws and faults using specialized measuring devices allows for improvements to the part during the development process. The plastic injection molding created using these measurements can be optimized and corrected.
The Process
Integral to all Injection Molding Manufacturers, the process begins with heating thermoplastics to the temperature best suited for its application. Frictional heat and external heating bands convert dry materials into molten plastic. This is injected into a plastic injection mold at high speed, with pressure. Inside the mold, the molten plastic cools and solidifies to form the part. Depending on the scale and complexity of the part, the system is either highly automated or involves human interaction.

Highly sophisticated measuring devices detect the inner geometry of injection mold parts. Surface inspection can be performed in a non-destructive way. Components of every type can be measured in their full form through 360 degrees of rotation. By detecting typical component errors, plastic injection molding can ensure repeatability with remarkable accuracy.
