  • How to Make a Plastic Injection Mould

    The design and production of a mold for mass production of injection molded plastics must be perfect, since an imperfect mold will create an imperfect part and lots of them. Also, because they are expensive, it is not a process that manufacturers purchasing molds for their production line want to mess around with. Quality metals, designs and function are all highly important in the mold making process. Steel and steel alloys such as stainless steel are popular choices for mold material because of their strength and corrosion resistance. Since these...

  • Getting the Perfect Prototype Part

    If you are a manufacturing company that is developing a new product that requires injection molding, then obviously looking for an injection molded plastics job shop is your first step in getting the part created. However, if you are hung up on the fact that you aren't sure exactly what you want, don't let it stop you from contacting an injection molding company. The process in and of itself always involves custom molds, and most companies therefore have the capability to help create a prototype that will suit your needs...

  • Christmas Toys from Plastic Injection Molding

    If Santa's workshop really existed, it would be full of elves with excellent industrial and commercial manufacturing expertise. Particularly because our modern society has demands beyond wooden toy soldiers and cloth dolls with yellow yarn hair and the population continues to rise, mass production would be vital for the survival of the North Pole. A system that would be working on overtime this close to Christmas would be the equipment for plastic injection molding. Plastic injection molding is one of the most common techniques for producing basic children's toys, such...

  • Avoiding the Pitfalls of Sourcing in China

    by Michael Bloom Chairman, Offshore Solutions, Inc. Abstract Considering sourcing in China? China offers raw materials, inexpensive labor and engineering skills. Then why do so many projects fail in China? Learn how to recognize the pitfalls of sourcing and then overcome them, how to organize a project, choose a manufacturer, and deliver high quality product to your loading dock on schedule. For U.S. manufacturers to remain competitive they must combine the best of American technology and advanced products with components built at lower offshore labor rates. "Purchasing Agents" are now...

  • Invention of Injection Molded Plastics

    John Wesley Hyatt was born on November 28th, 1837 in Starkey, New York. He started work as a printer at the age of 16, but in 1863, he was intrigued by an award offered by a New York billiards company who was looking for a cheap substitute for ivory for use in their billiard balls. The award was hefty at $10,000, and John Wesley Hyatt dedicated many hours of his time to finding this solution. Eventually, John and his brother found a way to make billiard balls by injecting celluloid...

Industry Information

Plastic Injection Molding

Plastic injection molding is the most common manufacturing technique in the modern world of manufacturing, and is used for products that we use in our everyday lives, such as bottle caps, children’s toys, and automotive dashboards. In the process of plastic injection molding, molten plastic is injected into a mold machine and is then solidified. Almost any plastic product can be made using a plastic injection mold.

The typical layout of a plastic injection molding machine consists of a hopper, which is a chamber in which the plastic pellets, or granules, are placed in preparation for heating. The next vital component is the heating chamber, where the pellets are melted down. In its molten state, other substances such as dyes or other chemical agents can be added in order to change the final product’s color and texture. The injection mold consists of two hollow cavities which clamp together under pressure. The cavities are injected with the molten plastic, are joined together, and left for a short amount of time to cool and solidify. Once solid, the two halves of the mold are separated, and the plastic product is ejected out of the mold by a set of ejector rods or pins.

Plastic injection molding is able to yield close-tolerance products at high-volume runs. Therefore, the process is frequently used for prototyping and mass production. Both of these processes are common in industries such as automotive, computer, plumbing, medical, food service and consumer. Plastic injection molding is utilized to some extent by so many industries due to how many advantages the process has. These advantages include:

  • Speed. Plastic injection molding is popular for long manufacturing runs because of its speed. The speed ultimately depends on the complexity of the product, but the downtime in between cycles generally lasts less than a minute. In addition to how fast the molding process itself is, the final product often times is finished as soon as it leaves the mold, and does not need to undergo any additional processes such as surface finishing.
  • Low labor costs. Most injection molding machines feature automated mechanisms that keep production going at a steady rate. Because so much of the machine is automated, they require little supervision.
  • Accuracy. The injection molding process involves filling a mold that is cut with the utmost precision. The structure of the molds as well as the pressure applied in the process ensure that there is very little variation in the product’s configuration from copy to copy.
  • Strength. Some injection molds feature fillers that reduce the plastic’s density during molding, and even after molding. In applications that require their plastic components to be exceptionally strong, plastic molding has strengthening capabilities that other processes do not.
  • Complexity capabilities and versatility. Since the injection molds undergo such high volumes of pressure, the molten plastic presses harder against the mold. As a result, the design of the part can feature highly intricate details. It is simple to change not only the type of material used to fabricate the products, but the additional chemicals that change the products appearance. Plastic injection molding machines can also be designed with co-injection molding capabilities. In other words, these machines can handle more than one material at a time.
  • Minimal waste. The process of injection molding is highly energy-efficient. Although the final product may include a joining line where the two halves of the mold cavity meet, the total amount of wasted plastic is very minimal and can be easily removed during the finishing process. The small amount of plastic waste that the process may produce can be recycled and reused.

In addition, another advantage to the plastic injection molding process is the broad range of materials that can be used. The choice of material typically depends on the intended purpose of the product. Thermoplastics are a common material that is used, because of its ability to become malleable once heated and rigid once it is cooled. Other materials that are used are thermosets and elastomers such as rubber. As beneficial as the plastic injection molding process is, it is not perfect. One disadvantage that comes with injection molding is the initial cost of the equipment. However, once the machinery is established and the mold is created, both will last a long time and be able to produce plastic components at a cost-efficient rate. Injection molding has many advantages that far outweigh its drawbacks, and is considered a worthy and beneficial long term investment by manufacturers worldwide.
