Custom Plastic Injection Molding

Featured image

Injection molding has been around for about 150 years, but modern advances bring precision, efficiency, and cost-effectiveness to this staple of manufacturing. So, what is plastic injection molding, and how can it provide quality, precision, and cost-effective parts for your manufacturing processes?

The process of injection molding involves injecting different melted materials into a mold where they quickly cool and are ejected as finished, hardened manufactured components. The ability of injection molding companies to produce several components that are accurately sized in just seconds makes the cost of plastic injection molding an efficient way to produce several different kinds of components. Materials used in the injection molding process include glass, thermoplastics, resins and polymers into precisely shaped products and product parts.

Injection Molding Machine for Plastic Parts Production

Continuing innovations mean that over 18,000 materials can be used in the injection molding process, so manufacturers can choose the material that works best for their products and product parts. Whether you use glass, resin, or plastic for your injection molding products, the fundamentals of the plastic and metal injection molding processes are similar. Depending on the materials used and the complexity of the end result, there can be wide variations in injection molding costs. However, working with a knowledgeable manufacturing partner who understands the nuances of adjusting the manufacturing process will get you the most out of the materials used and could reduce the cost of plastic injection molding.

One of the most experienced and knowledgeable plastic injection molding companies in Ohio, or in the U.S. for that matter, has the experience in plastic injection molding that will meet the needs of your projects. When searching for “plastic injection molding companies near me” be sure to visit websites that will help you determine which injection molding companies are qualified to handle your materials and produce the results you require.

Plastic Injection Molding for Fast-paced Production

The evolution of the plastic injection molding machine has made plastic injection molding products easier to produce, more durable, and increasingly less expensive. Like so many other industries, as the cost of technology has decreased, so has the cost of plastic injection molding. But also similar to technology trends, the quality, reliability, and speed of production for plastic injection molding has increased, even as the cost goes down. Working with plastic injection molding companies that meticulously assist in planning your plastic injection molding project will bring you into a collaborative process that ensures success.

Modern Production with Injection Molding Machines

The functions of plastic injection molding machines may have evolved some over time, but they all essentially have three different parts to them: the mold, clamps, and an injection unit. As part of the 20th century developments in the injection molding process, the injection unit includes a heated barrel and a screw mechanism that feeds the materials used, usually in the form of small pellets or beads. As materials advance up through the injection unit, they are heated until they are pushed, in melted form, into the molds.

While the machine is certainly doing all the work at this point, working with an injection molding company that can translate your manufacturing components to accurate and efficiently produced parts is important. An integrated engineering team as a part of the injection molding company that you choose is vital. This will ensure that molding is done in a way that considers ideal materials properties, and the best size, shape, and layout of the mold. This will also help guarantee that the best plastic injection molding machine is used for your manufacturing needs.

Understanding the Cost of Injection Molding

Injection molding costs vary according to the size, complexity, quantities needed, and materials used. While there is a wide range of costs associated with injection molding, it can still be a very cost-efficient production method. For the development of simpler, smaller molds, this lower cost can make injection molding ideal for developing a small number of initial prototypes.

As your injection molding projects become more advanced, you need to understand more than just injection molding cost. For companies that attempt to low-ball the cost, you may be sacrificing the expertise of highly trained specialists who understand the importance of the right machine and properly mixed materials for each project.  This could cost your project unnecessary expense and delays.

Experienced Injection Molding Companies

While many plastic injection molding companies can produce basic designs in plastic that are easily replicable, it takes a more experienced injection molding company with specialized plastic injection molding machines to bring more complicated designs to fruition. Experienced companies will not only understand the manufacturing process, but also provide the engineering consultation services, refined injection molding cost estimations, and the materials’ management that can protect your supply chain for the long run.

Be sure to ask questions about the complexity of projects in the portfolio of the injection molding company that you consider. Think about the different materials they have experience with and the variety of machinery that can be used to produce the best results. When it comes to plastic injection machines, there are no one-size-fits-all solutions.

Multi-Shot Molding in 240, 730, & 1000 ton

The two- or three-shot injection molding process is relatively simple. One material is injected into a mold to make the initial section of the product, followed by a second or even third injection of different materials that are compatible with the original material. One machine cycle reduces the number of required product runs while allowing for larger quantities, consequently decreasing labor required to mold parts. It ensures strong bonds between materials without the need for further assembly, resulting in improved aesthetics, ergonomics, and durability. It’s an efficient, cost-effective process that results in higher quality and greater product versatility.

Insert Molding

Insert molding incorporates highly advanced equipment to develop innovative, complex products through the process of molding or forming plastic parts around other, non-plastic parts or inserts. The inserted component is most commonly a simple metal object; however, non-metal materials can also be utilized. This process also allows for flexibility in various markets and incorporates partner technology to produce accurately designed plastic parts.

Robotic Part Handling

Robotic part handling involves putting parts through an assembly process and the transferring, feeding, or removing of parts or tools from machines. End-users utilize robots to improve throughput, quality, flexibility, and consistency while eliminating employees from potentially hazardous jobs. Robotic part handling helps in quick changeovers from one product to the next, can handle a high mix of products, and adjust to throughput demands. Robot technologies are increasing for optimum precision and production during the manufacturing process.

Automated/Robotic Part Trimming

Automated/robotic part trimming is a material separation process that takes place when a router bit, attached to a high-speed automated routing spindle (on the end of the robot), is driven into a part and robotic router head. Then it is guided along the area to be trimmed with clean edges to a predetermined depth. Part trimming delivers flexibility, productivity, safety, quality, and cost-competitiveness to enhance production results considerably.


Overmolding is a process that combines two or more molded plastic or elastomer parts into a single finished product. In the overmolding process, the base layer gets molded first, and then the additional plastic layers are molded over and around the original part. It creates customizable solutions to perfectly match the unique mold design specs and particular needs of the overmolding project.
