Frequently Asked Questions About Plastic Injection Molding

What are the steps of injection molding?
The four basic stages or steps of injection molding include clamping (closing the mold together), injection (heated plastic is injected into the mold), cooling (allowing the part to harden for the exact amount of time), and ejection (releasing the part). At a high level view, injection molding is a fairly simple process; however, there are lots of smaller details and processes that makes working with an experienced manufacturer of the injection molding process critical. Understanding the injection molding process step by step is what allows us to produce quality products every time.
Which products can be made by injection molding processes?
Injection molded products and injection molded parts are very prevalent. Examples of injection molded parts include household products like plastic bottles, bottle caps, furniture, flower pots, toys, and hangers. However, these are just a very small handful of examples of products that use the injection molding manufacturing process. Since the manufacturing process for injection molding can be customized for almost any shape or size, the injection molding process is one of the most versatile manufacturing processes available. We specialize in custom components that have been used in a variety of products and industries including life sciences, electronics, medical, military and defense and much more.
What are the limitations of injection molding?
Injection molding has many advantages including allowing for the creation of complex parts, compatibility with many materials and colors, and its efficiency and reliability. However, because injection molded parts require the creation of custom tooling and a mold, startup costs can sometimes be higher and lead times may be longer. Reach out to us to determine whether the injection molding process is the right manufacturing solution for you. We can help to weight the advantages and disadvantages of the injection molding process in order to make sure that your project is successful.
What type of materials can be processed through injection molding?
One major advantage of the injection molding manufacturing process is that there are countless materials that are compatible with injection molding. We specialize in Ultem and Peek; however, we are able to work with almost any resin. Reach out to us to discuss the many considerations when determining the right type of material for your injection molded part.
How to determine what type of material to use with injection molding?
There are many types of materials that can be processed through injection molding and therefore a few key factors need to be considered. The application, or where the plastic part will be used, is key to determining what type of environmental factors and conditions should be taken into consideration. Looking at how strong the material needs to be is important so that the plastic part is hard enough to withstand abrasion, temperature and other challenging conditions. Lastly, the appearance is an important piece of the puzzle. Some resins will change appearance once a new color is added and whether the part will be visible or not is important to deciding the right material to be used in the injection molding process.
What are some different types of injection molding processes that you can assist with?
Our additional capabilities include insert molding, over molding, tool building, sonic welding, EMI shielding, product assembly, hot stamping, and class 10,000 Clean Room molding. We also can assist with product design and prototype tooling.
