From small gears and kids’ toys to auto parts and medical parts, plastic injection molding is used to make a variety of consumer products. It’s a highly effective, and efficient, way to produce large volumes of plastic products. After creating a mold, manufacturing companies can use it to produce countless products in that same size and shape. But what exactly is plastic injection molding?
Plastic injection molding is a molding process characterized by the use of thermoplastics. Plastic injection molding specifically uses thermoplastic as the raw material that’s poured into a mold.While it has undergone numerous improvements and changes since, plastic injection molding has origins dating back to the 19th century. In 1872, brothers John and Isaiah Wyatt patented the first injection molding machine, which they used to inject heated plastic into a mold.
Also known as thermosoftening plastics, thermoplastics are polymer materials that temporarily become softer and more pliable when exposed to heat. During plastic injection molding, thermoplastic material is heated until it turns from a solid state to a liquid state, at which point it’s poured into the mold.
Thermoplastics are ideal for injection molding because of their ability to become pliable when exposed to heat. Furthermore, excess thermoplastic material can be easily recycled, thereby reducing waste for manufacturing companies. How Plastic Injection Molding Is Performed
Before plastic injection molding can be performed, a mold must first be created. Common materials used to make molds for plastic injection molding include stainless steel, high-carbon steel and aluminum. For high-volume applications, though, steel is preferred because of its superior strength and resistant to wear than that of aluminum. Steel molds can easily last for hundreds of thousands of applications, making them a cost-effective solution for manufacturing companies that produce large volumes of plastic products.

Steel molds can easily last for hundreds of thousands of applications, making them a cost-effective solution for manufacturing companies that produce large volumes of plastic products.
Once the mold has been created, thermoplastic material in the form of small pellets are fed into a large drum-like barrel where they are heated and pushed sideways towards the mold. As the injection molding machine’s screw pushes the liquefied material, the material eventually reaches a nozzle that further pressurizes and pushes the thermoplastic material into the mold.
Next, the liquified thermoplastic material is cooled — typically at room temperature — until it hardens. Depending on the type of injection molding machine used, it may feature a platen that opens after the material has cooled, allowing for the removal of the newly created plastic product.

Designing and producing custom injected molded parts is a fairly complicated process. Though there are some fairly obvious components to this endeavor, there are also some less obvious aspects that must be considered and perfected. Let’s take a look at the most important items to consider before diving into the injection mold design process. Define the Physical Properties The physical properties of the custom injection molded part must be defined at the outset of the process. Of critical importance is the part’s caliber of strength, amount of stiffness, impact resistance level, electrical concerns, wear/scratch mar and whether it needs to be flame retardant. Environment Take some time to think about the types of chemical exposure the custom injection molded part will be subjected to. If it can’t withstand the rigor of such exposure, the design must be revised. Consider the level of warmth and humidity the part will be subjected to. If it fails to function when the temperature and humidity rise, the part’s design must be altered. Perform extensive temperature-failure analyses prior to the production of the injection mold design.
Additional environment considerations include stress cracking, UV-define failure-color and property/material degradation due to wear and tear. Cost Establish a reasonable cost target. You must figure out exactly how much the product will cost to produce. Furthermore, the price of the product for sale should also be defined. Aesthetic Concerns Though utility is the utmost concern when it comes to injection mold design, the part’s look also matters. Consider what you would like the surface appearance to look like. The part’s color and decorations should be selected prior to the start of production. Compliance Issues Consider compliance concerns before commencing production. The part must be in compliance with regulatory and agency standards. Consider the Project Origin Take some time to define the project origin. The subtleties of the injection mold design process hinge on whether it is a new project design, a new product, new application, a metal-to-plastic conversion or a new product that is meant to replace an alternative material. Mold Ability Consider whether the part fits injection molding capabilities. Determine if the identified resin is appropriate for the part’s idiosyncratic design. Perform a mold flow analysis.
The considerations outlined above all play important roles when deciding on injection mold design. The most successful projects are launched without flaw due to a completion of research during the design and conception stage. Everyone from engineers to resin suppliers, molding vendors and beyond will play an important role in working through the considerations outlined above.Designers, engineers and other relevant team members will prove essential to the successful development and design of plastic injection molded components.

The small stuff matters a great deal when it comes to custom plastic injection molding parts. Plastic parts are generated from molds that are extremely detailed. The mold design is typically created with the assistance of engineering design experts and the manufacturer’s specialists. Once the design is finished, work must be done to ensure the end product is of acceptable quality. An alliance with the proper manufacturer will generate products that look highly detailed and polished to perfection.
Price is also worth mentioning. Custom injection molding has become quite the popular method for the generation of plastic parts partially because it is not egregiously expensive. Do some digging into the pricing of custom injection molding and you will find the prices are quite fair. It is possible to generate a wide variety of materials in considerable quantities without breaking your budget. Part of the reason why this process proves affordable is the fact that it is almost always fully automated. This level of automation spurs a high output rate that allows for mass production at reasonable prices.
The Price of Custom Plastic Injection Molding Custom plastic injection molding involves varying costs that result from different portions of the process. The final cost of a specific project hinges on all sorts of variables. Different techniques like blow molding and thermoforming have idiosyncratic costs. Though the mold is central to cost, the subtle details of each particular project matter a great deal. A quote for custom injection molding is determined by input like drawings, sample parts, prototypes and beyond. Each input must be analyzed to pinpoint the ideal molding solution.
Everything from tolerance tightness to additional cavities, mold size, core metal, core machining and part complexity impacts the price of custom plastic injection molding. Do not assume this process is beyond your company’s price range. Determine what you are looking for from the custom plastic injection molding process, obtain a quote and you will likely be pleasantly surprised as to how affordable it is.

Custom plastic injection molding is favored by plastic parts manufacturers across the globe for good reason. There are all sorts of advantages to this molding method. This is not the only way to process plastic yet it has quickly become the most preferred method. Here’s a look at some of the benefits of custom plastic molding along with a few drawbacks.
1，The Utmost Efficiency
Custom plastic molding is incredibly fast. This is one of the major reasons why it has gained such popularity as a technology for long manufacturing runs.
Though the exact speed of the process hinges on the nature of the mold, it usually takes between 15 and 30 seconds to progress between cycles.
2，It Keeps Labor Costs Low
Custom plastic molding is an automated process. Just about all the work is performed by robotics, computers and machines. Plastic injection molding equipment functions with a self-gating, automatic technology that allows for uninterrupted operations that require minimal oversight. A single person can control each of these processes.
The end result is reduced overhead expenses thanks to the dramatic decrease in labor and manufacturing costs. Post-production work is limited as the parts are highly precise, strong and finished upon generation.
3，It Creates High-strength Components
Those who need uber-strong parts use plastic injection molding. Custom plastic molding allows for the addition of fillers to components when processing occurs. These fillers decrease the density of the liquid plastic and bolster the strength of the final product.
4，A High Level of Accuracy
Custom plastic injection molding is incredibly precise. This process fabricates just about every type of plastic part. Though some design limitations exist, the molds are built so the final product is within 0.0005 inches of the intended result.
5，Remarkable Flexibility
The plastic injection molding process is quite flexible. The material type can be changed with ease. Even the color the plastic part is to be produced in can be altered without an abundance of time or effort. The extent of this process’s flexibility is nearly limitless regardless of the produced part’s specific size.
These injection molds are exposed to incredibly high pressures, allowing the molds to be pressed tighter than other molding methods. The use of computer aided manufacturing (CAM) and computer aided design (CAD) allows for even the smallest subtleties and most complex of designs to be flawlessly implemented in the part’s creation. It is even possible to experience egregiously tight tolerances of .001 or more.
6，The Custom Plastic Molding Process is Economically Efficient Compared to Plastic
Though it certainly costs some money to create an initial mold, all sorts of plastic components can be created at little cost once the mold is built. Massive production runs that make use of plastic machining often cost upwards of one-quarter more than custom plastic injection molding. Some manufacturing experts report a large production run with plastic injection molding is 25 times less costly than plastic machining. It is clear that this method of producing plastic parts is well worth the initial investment.
7，Custom Plastic Injection Molding is as Resourceful as It Gets
Plastic injection molding is resourceful in that it does not use any more plastic than necessary to generate parts. Unused plastic is ground up and melted in order to be recycled. Furthermore, the part molds’ high tolerance minimizes waste in the manufacturing process.
8，Dexterity
Injection molding machines are designed to process several different plastics simultaneously. Compatible materials are often used in a single injection mold in which the core material is fully encapsulated. The advantages of this process range from enhanced strength to cost minimization and decreased energy use thanks to the secondary’s plastic’s lower melting point.
The Few Disadvantages of Custom Plastic Injection Molding
Custom plastic molding has a couple flaws of note. The process is fairly expensive at the outset. It can cost a thousand dollars or more to produce an initial mold. The machinery is also fairly expensive. However, once these start-up costs are surmounted, this process pays for itself and then some across posterity.
Additional cons include the fact that parts have to be designed in a nuanced manner for highly effective molding. In some instances, molding considerations can constrain the parts’ design.
