Injection Moulders: The Machine

The machines that practice injection molding create the plastic products that surround us regardless of the context we are in, as long as we are within civilization's bounds. In fact, even campers encounter plastic products when wandering into the wilderness, because they bring plastic items with them in the form of tents, bottles, food packages and so forth. Understanding how injection moulders' work further explores the significance of this process and the many products we utilize on a daily basis. The most basic plastic molding machine contains a sparse number... Read More

Cutting Costs in Injection Molding

Injection molding is one of the least expensive molding processes in the plastic industry. Because of this, injection molded plastic is used for creating millions of plastic products each day, from small plastic fasteners to plastic dishes and more. However, costs can still rise due to factors such as increases in plastic prices, problems with the machine, or even changes in the product lines. If a manufacturing company wants to keep prices low, they can try some of the following steps to keep injection molded plastic costs down: Plastic types:... Read More

Custom Injection Molding: A Manufacturing Must

Because every industry must look towards the future to ensure their place in it, custom manufacturing is a must in every industry. This is how new products are created, through the creativity and experimentation of custom manufacturing. Custom injection molding in particular is necessary for the prototypes that precede new products. Without injection molding companies willing to make custom molds for prototypes and specialized product manufacturing, we would be stuck with the same old products we have now. Without progression in industrial design that industry will fail. Injection molded plastics... Read More

Rapid Injection Molding: Prototypes and Short Production Runs

When discussing production processes like how injection molded plastics are made, there will obviously be short-cut processes that utilize the basics of the original but are able to do it faster and for smaller quantities. There are a number of reasons that a method like this, such as rapid injection molding, is necessary. When a company is developing a new product, they need to create prototypes to test before they run a full-line production. Sometimes a company needs a limited supply of products that are significantly fewer then the average... Read More

The Fascinating History of Injection Molding

Although metalworking and woodworking are two product development processes that have been around for centuries that does not mean that they are the only two interesting histories as far as production evolution goes. Plastic belongs to the 19th and 20th century, the material utilized more then any other to serve tasks in our daily lives as well as producing the manufacturing products that make the everyday products possible. The types of plastic now are numerous, although when it was first developed in 1861 by Alexander Parkes there was only one... Read More

Save Energy with Injection Molding Labels

Injection molders require a large amount of energy to operate. The machines complete many different processes at once, including heating and softening the plastic, pressing the plastic into the mold, cooling the plastic, and releasing it from the mold. All of these processes require many different motors and moving parts to complete quickly and effectively. Some units even have computers that evaluate the quality of the item before it is released from the machine, which requires an even greater amount of energy. In recent years, many factories have tried to... Read More

Injection Molding

Roughly 32% of all plastic processing applications utilize injection molding. Injection molding is the most common plastic processing method today, and enables manufacturers to fabricate plastic products in configurations that vary in complexity. Injection molding can be used to fabricate items such as automotive parts, computer parts, medical equipment, toys, tools, and office supplies. Other examples include screwdriver handles, video game cartridges, mop buckets, monitors, contact lens containers, and catheters. In almost every industrial or consumer industry, injection molded parts are used to some extent.

Thermoplastics is the most common material used for the injection molding process. However, elastomers, biodegradable plastics, and thermosets can also be used. More specifically, materials that can be used for injection molding include ABS, polycarbonate, and polypropylene. Some materials, however, are more expensive than others. To keep costs low, manufacturers may find an alternative type of plastic for the fabrication process. Researching the pros and cons of various types of plastic can keep costs at a minimum. For example, not all plastics can be recycled, but materials such as polystyrene, polyethylene, and nylon can. One of the best ways to save money during the production process is recycling and reusing plastics. Many manufacturing companies have representatives that will help customers in choosing the right product the first time, which will fulfill the needs of the customer quickly and save the company money.

The injection molded process itself comes with a variety of advantages. The process has a high production rate, and little to no need for further processing upon completion of the injection molded part. Despite the high tooling cost, the injection molding process has a very low production cost per part. Injection molding is the process of choice to produce highly complex items that no other process can create. Additional advantages include energy efficiency, precision in forming parts, and that it produces a small amount of waste.

Hydraulic oil machines are the most common type of injection molding. These machines use hydraulic fluids to propel the mold through the machine. Toggle injection molding comes in at a close second in terms of popularity, Toggle injection molding machines move the mold through the machine using mechanical links. In recent years, hybrid hydraulic and toggle machines have emerged into the injection molding industry and are increasing in popularity, due to their ability to eliminate the problems that the other machines may have, such as rapid wear and tear of the equipment, and slow processing rates for parts.

The injection molding process remains the same regardless of which machine is ultimately used. In the first step, the barrel section of the machine is heated. The next step involves placing the pellets, or granules, into a hopper. Inside the hopper, a screw mechanism forces the granules into the heated barrel, where the granules are melted down. The molten plastic is injected into a split die chamber mold cavity. Once the cavity is full, it is clamped shut. Additional fluids such as water circulate through the mold’s cooling system and remove the heat. The part is held in the mold under a high amount of pressure until it completely hardens. Finally, upon the solidification of the part, it is extracted from the mold.

Rapid injection molding is another process that can be utilized. It is the same as normal injection molding, using the same materials and the same type of molds, but it is quicker and has a lower production cost. Because the molds go through the process at a much quicker rate, they need to be of the utmost quality. In the early stages of developing a new product, a company will need to develop a prototype before production of that item can begin. Alternatively, they may request that a product be made in a limited quantity as opposed to it being mass produced. Therefore, rapid injection molding is a recommended process for prototyping and small-scale production. Toys, gears, and enclosures are common items that undergo prototyping. Industries that frequently utilize rapid injection molding for prototyping include appliances, aerospace, electronics, automotive, and medical.

Injection molding machines are made up of a network of motors, heaters, and moving parts that require an extensive amount of energy to carry out their functions. Over the years, research has been done to make injection molding machines more energy efficient. One method that has been developed is a labeling system, which displays the rate of energy that is used by the machine. Regulated consumption of energy can help save a company money in production costs, and a labeling system is anticipated to assist in making that happen.
