The injection molding process involves melting plastic resin pellets and injecting the molten resin into a metal mold under high pressure. The mold is then cooled down before being opened to reveal a solidified shape that has conformed to the shape of the mold cavity. The process is repeated as many times as designed to make the required number of parts. Injection molding is used to create a wide range of plastic parts with intricate feature requirements and complex geometries. These components can be found in a wide range of everyday items, from consumer goods to industrial components. Below is the typical application of injection molding.
The typical application of injection molding
#1 Food and Beverage
In the Food and Beverage Industry, injection molding can be used. The food and beverage industries rely heavily on plastic materials for product packaging and containers when it comes to injection molding. Plastic injection molding is an obvious fit to ensure various specifications are met, including BPA-free, FDA-certified, non-toxic, and GMA-safe regulations, because this industry must adhere to strict sanitization and safety regulations. Injection molding is ideal for the food and beverage industry’s packaging and container needs, from bottle caps to TV, and dinner trays.
#2 Automobile Components
Injection molding has applications in the food and automotive industries. Many of the parts found on modern automobiles necessitate a wide range of intricately designed features in order to function properly. As a result, many automotive industry leaders have turned to plastic injection molding to develop, plan, and manufacture the parts they require. Bumpers, dashboards, and smaller pieces such as cup holders and mirror housings are examples of injected molded elements.
#3 Medical Devices and Parts
Injection Molding can be used in Medical Devices Industry. Medical injection molding is a process used to make components for medical devices. In this process, liquid plastic material is injected into a metal die or cavity. Plastic injection molding is critical for medical and pharmaceutical products because many medical products must be shatter-proof, non-porous, and perfect with complex geometries and intricate features. Furthermore, they can be sterilized by steam or radiation without being harmed and are resistant to blood, body fluids, and other biological contaminants.
Injection molding can be used to create medical components such as pill bottles, syringes, IV tubing, drug delivery devices, Petri dishes, and medical x-ray parts. Injection molding of medical parts is an excellent method for producing a wide range of complex components for the medical industry.
The medical industry can benefit from injection molding’s shorter production times and lower production costs while still producing high-quality medical-grade products.
#4 Household Products
Injection Molding can be used in Household Appliance Industry. Injection-molded products or parts can be easily found in your own kitchen like food contact products and kitchen appliances. Plastic injection molding parts for household products have many advantages, such as being lightweight, high strength, corrosion resistance, and good electrical insulation. Like other industries, household injection molding products can be made more affordable by high-volume production.
#5 Agriculture Industry
Injection Molding can be used in Agriculture Industry. Historically, the agriculture industry would invest in metal-made components simply because they provided a long-lasting solution. Reinforced plastic options are now common due to new plastic material properties such as UV resistance, impact resistance, humidity resistance, and much more. Plastic injection molding is an obvious fit for the agriculture industry, from feeding troughs to specialized harvesting components, due to its ability to create durable agriculture products that withstand the elements on a farm.
#6 Electronics Industry
In the Consumer Electronics Industry, injection molding can be used. Although many people think of electronic components as primarily metal pieces of machinery that run on electricity, using corrosion-resistant plastic housings to extend system longevity improves overall performance. As you might expect, manufacturing housings via plastic injection molding processes is preferred. Plastic injection molding is used in many products, from the computer mouse you’re using right now to the television in your living room.
