Custom plastic molding is a method used for making parts from both thermosetting plastic materials and thermoplastic in production. Through this process, plastic is injected at high pressure into a mold which is the inverse of the shape of the product. Custom plastic molding is generally used for manufacturing a variety of parts, from the smallest component to packaging.
Custom plastic molding is the most common method of production, with some commonly made items including screen filters and manufactured plastic parts. Custom plastic molding will produce thousands of parts in all different shapes and sizes, no project is too big or too small for us to handle. Custom plastic injection mold design and production of tools give your company the ability to transform your project from concept to reality.
Custom plastic molding process involves taking plastic in the form of pellets and heating these bits and pieces until a liquefied state is obtained. This transition is called plasticizing. The pressures may tend to rise and cause flashing or short shots in the part if the melt temperature is too low.
If the temperature is too high you should encounter the mechanical failure of the part due to material degradation. In this process, you should remember as if your part is not able to accept the melt without suffering other problems you will have wasted time and money.
Plastic has become one of the most important things in our life. There are so many things from plastic that it is hard to imagine what our lives would be like if it was never invented. With so many of our everyday products being made of plastic, it is easy to understand why custom plastic molding parts are such a huge industry.
Plastic molding can also custom mold a wide variety of plastic products which is called custom plastic molding including garden pots, food backage box, plastic storage box, plastic chair, cabinets, office trays and boxes, barriers, barricades and traffic signage and displays for product and marketing promotions. If you are planning to go into plastic molding business, you should first know the different processes. Choose from a plastic molding process that fits your budget, your expertise, and your resources. Here are the basic definitions of various methods of plastic molding.
Many manufacturers use this custom plastic molding that always been a fast-moving, chaotic, and challenging business. It also has an elevated possible for a profit, even today, despite the international competition and tight margins. You want to be a success, you see the possibilities, but the global pricing and high expenses make it very difficult.

What is Rapid Injection Molding?
Rapid injection molding or rapid tooling injection molding is a popular manufacturing technique that has been idolized for years. Rapid injection molding is similar to conventional molding, yet different enough to affect how parts are designed. This technique lets companies quickly get low-cost and dimensionally accurate prototypes as well as low-volume production parts from plastics.
Rapid injection molding falls between rapid prototyping and conventional injection molding. This technique supports prototyping, bridge tooling, and low-volume production. Additive methods such as FDM and SLA work well for testing form and fit, but often such parts are not a substitute for testing with real injection molded parts. Rapid injection molding is also fast and cost-effective enough to fix problems when initial designs are not quite right.
Rapid injection molding has increased the quality of a final product by increasing the time companies have to test designs. Some manufacturers did quite a bit of testing with rapid prototype based polyurethane castings, but because the material properties of cast materials can differ significantly from those of injected molded resins, many times testing left unsolved.
What is What is Rapid Injection Mold or Proto mold?
Rapid injection mold and proto mold are two different terms that refer to the same thing. They both describe a type of mold used in rapid injection molding, which is a manufacturing process that allows companies to quickly produce small to medium-sized batches of plastic parts or products.
A rapid injection mold or proto mold is typically made from aluminum or soft steel, which can be created quickly and cost-effectively compared to traditional injection mold. These molds are designed to be used for a shorter period of time and for lower production volumes than traditional injection molding molds.
The use of rapid injection molds or proto molds in rapid injection molding allows companies to quickly produce prototypes or low-volume production runs of plastic parts or products. This process is faster and more cost-effective than traditional injection molding, which requires more time and expense to create molds.
Rapid injection molds or proto molds are a valuable tool for companies that need to quickly produce high-quality plastic parts or products for prototyping, low-volume production, or quick-turnaround projects.
Difference between Rapid plastic Injection Molding and production injection molding
The main difference between rapid plastic injection molding and production injection molding is the production volume and the lead time.
Rapid injection molding is a fast and cost-effective way to produce small to medium-sized batches of parts or products. It uses advanced software and machinery to create molds quickly and efficiently, which reduces the lead time and turnaround time. Rapid injection molding can produce parts or products in a matter of days or weeks, making it suitable for prototyping, low-volume production, and quick-turnaround projects.
Production injection molding, on the other hand, is a more established method of producing parts or products at a larger scale. It involves creating a mold and then injecting molten material into the mold to create the final product. Production injection molding is best suited for larger production runs and can produce high volumes of parts or products at a lower cost per unit. It is ideal for long-term production projects that require consistent quality and high-volume output.
Another difference between rapid tooling injection molding and production injection molding is the cost. Rapid injection molding has higher upfront costs due to the investment in advanced software and machinery. However, it can be more cost-effective for small to medium-sized production runs. Production injection molding, on the other hand, has lower upfront costs and is more cost-effective for larger production runs.
In summary, the main differences between rapid injection molding and production injection molding are the production volume, lead time, and cost. Rapid injection molding is faster, more expensive upfront, and best suited for small to medium-sized production runs, while production injection molding is slower, less expensive upfront, and best suited for larger production runs.
The technique of rapid tooling injection molding
The technique of rapid tooling injection molding makes testing much more beneficial. It is because everyone knows that new products must pass extensive design, prototype evaluation, and functional testing before they are considered ready to distribute to markets. In this case, rapid injection molding becomes one of the best techniques for prototypes that need to undergo design changes during the developmental stage.
By rapid injection molding technique, you can make as many prototypes as possible needed to get the best products, or you can name it pilot production. It is perfect for market testing until the production plastic mold is ready, or about a three or four month wait. When production volume does not justify to make prduction plastic mold, this molding technique can supply production parts.
If you never knew the process of rapid injection molding, the following can help. The process uses aluminum molds milled on 3-axis CNCs instead of the expensive, hardened tool steel molds used with traditional methods. Molds comprise an A-side, sometimes called the cavity side and a B-side, sometimes called the core side. The A-side mounts to the fixed portion of the injection molding press.
Then, in rapid tooling injection molding, resin is injected through this section of the mold into the part cavity by way of the sprue, the path the resin takes until it reaches the runners. These guide the resin to the gate, the location where the plastic enters the part cavity. The B-side, on the other hand, mounts to the moving side of the press and includes the steel ejector pins. Before designing the mold, parts are oriented so they will remain on the B-Side when the mold opens.
The process of rapid injection molding also requires technology, such as 3D CAD with high speed CNC machining equipment to quickly manufacture injection molds. This way is efficient, as it enables the low cost creation of injection-molded prototypes and makes low volume runs of production parts affordable. It allows manufacturers to get prototypes in just few days. It is also a way company’s image since it lets you to have more preparation before launching products.

What is injection molded parts for?
Injection Molded Parts is plastic parts that are produced through plastic injection molding. It is known that plastic is known to be a very versatile and economical material that is used in many applications. Your computer monitor, mouse and keyboard are the examples of Injection Molded Parts.
Injection molded Parts is created by using an injection molding machine, which works by melting plastic pellets, and injecting them into a mold. Related to the case, designing plastic parts is a complex process, and the manufacturing end of it must be taken into account during the design phase. There are three elements of an injection molded plastic part; the nominal wall, projections, and holes and recesses.
The nominal wall as the first element of injection molded plastics refers to the wall thickness. The wall thickness throughout the part should not vary by more than 10 percent. Varying wall thicknesses in the injection molded plastic parts is one of the main causes of flawed product.
How to design injection molded parts
In designing injection molded parts, people usually avoid excessively thick walls, simply because thick walls use more plastic, and are more expensive to produce. However, there is a limit as to how thin the part can be as well. The strength of the part is a function of the thickness, and the final use of the product will determine the desired strength. Some specialized injection molded plastic parts require reinforcement with glass or carbon fibers.
A projection is another element of injection molded parts that projects out of the nominal wall, such as reinforcement ribs. The ribs must not be thicker than the nominal wall, or else sink marks may result.
Recesses and holes are also a major design element of plastic molding parts. The location of any holes or recesses may significantly affect the part’s overall strength. Trying to create a hole in the side of a part is especially challenging, and the need for side holes should be minimized in the initial design.

Besides the three elements of injection molded parts mentioned above, another design factor is the corners of the part. How the plastic enters and fills the mold is of great concern. Because melted plastic is a fluid, fluid dynamics will dictate the design as well, to a large extent.
In this case, the plastic molding parts will flow better during injection if corners are rounded. In the other hand, the plastics will pull against a sharp corner during the cooling process, and a flawed part may result. To result in a stronger part that is less likely to crack or break, creating a low stress design with smooth transitions is a must.
There are two types of materials used in injection molded parts: thermoplastics and thermoset plastics. No matter what type of material is used, it is generally supplied in a granular or powdered format. Leftover and scrap materials from thermoplastics can be recycled, while those from thermoset plastics cannot, due to their chemical transformation during the mixing and curing process.
Types of thermoplastic materials used for plastic molding parts include: polystyrene, acrylonitrile butadiene styrene (ABS), polyimide, polypropylene, polyeththylene, and polyvinyl Chloride (PVC). Meanwhile, thermoset plastics consist of two or more base materials that are mixed together and then the mixture undergoes a chemical reaction to create a new material. Types of thermoset plastics used in injection molding include epoxy and phenolic.
Injection molding allows manufacturers to produce quality plastic components repeatably in a cost-efficient manner. As a result, injection molded parts are used in nearly every industry, from toys to automobile components.
