FAQ

What Is Plastic Injection Molding

Plastic Injection Molding refers to the type of manufacturing technology used to produce high performance plastic components of varying complexity. An assembly line of specialized machines melts, injects, and casts plastic into the shape of a given mold. Plastic injection molding produces plastic parts with high precision and consistency in shorter lead times.

The process begins with mold design, where a mold is made from steel or aluminum materials that meet a part's specifications. CAD design is often used to create a prototype mold before the final mold is used in the production process. After selecting the proper plastic material based on compatibility with the mold, the plastic resin is melted and injected into the mold cavity. After the mold cools, the solidified plastic is ejected from the cavity, ready for surface treatment. Excess plastic is also removed to ensure cleanliness.

Advantages of Plastic Injection Molding

Plastic injection molding offers many advantages in terms of improving production efficiency, machine performance and promoting safety standards.

Production of complex shapes

Although speed can vary depending on the size and complexity of the parts and molds being produced, plastic injection molding typically runs 15 to 120 seconds per cycle. With faster production comes higher profit margins.

Complex part design

With automated equipment and the right design, plastic injection molding can produce highly complex parts with uniformity, producing large volumes in short lead times and using less energy. Manufacturers consider wall thickness, corner transitions, vent placement, weld lines and other features to ensure plastic parts perform as intended.

Flexible material options

A wide range of material options are available to help manufacturers meet varying requirements for flexibility, heat resistance, elasticity, water absorption, and impact resistance.

Reduced waste

Advanced technology reduces the waste generated during plastic injection molding by recycling the waste material for future use.

Low labor costs

Plastic injection molding machines maintain streamlined production and handle multiple functions, freeing employees to perform more pressing tasks for the company. Working with automated tools helps reduce the need for additional human labor and labor costs.

Surface Finishing

Plastic injection molding also makes parts more receptive to various surface coating and finishing options, from glossy to matte. There are many color options and masterbatches that can be customized for branding or other needs.

Plastic Injection Molding Materials

Polyethylene (PE): The most widely used plastic in the world, this chemically resistant polymer comes in two types: the opaque high-density polyethylene (HDPE) and the more flexible low-density polyethylene (LDPE). PE is best suited for making housewares and automotive parts.

Acrylic (PMMA): With its clear surface, acrylic, or poly(methyl methacrylate), is translucent, shatterproof, lightweight, and resistant to ultraviolet rays and extreme temperatures. Because of its lightweight properties, acrylic is better suited for making aquarium tanks, windows, solar panels and bathroom cabinets.

Acrylonitrile Butadiene Styrene (ABS): With a low melting point, ABS can be easily molded into any desired product and supports various colors, textures and finishes. ABS is ideal for making keyboard keys, sports equipment and protective headgear.

Nylon (polyamide): Also known as PA, nylon comes in four main grades: 11 for outdoor applications, 12 for the lowest melting point, 46 for the highest operating temperature, and 66 for acid resistance.

Polyoxymethylene (POM): Also known as acetal, polyoxymethylene is stiff and resistant to chemicals, and works well to make knife parts, eyeglass frames, and lock systems.

Polycarbonate (PC): A naturally transparent material, polycarbonate retains its color and is stronger than glass, making it suitable for making windows, safety goggles, automotive parts and silicone molds.

Thermoplastic Polyurethane (TPU): Replaces hard rubber and has excellent temperature resistance and strength, making it ideal for sportswear and footwear.

Thermoplastic Elastomer (TPE): A combination of plastic and rubber, TPE easily retains its shape after stress and is more cost effective to mold into weather seals and medical devices such as breathing tubes.

Plastic Injection Molding Applications

Through its ability to produce complex parts and products, plastic injection molding has helped in the following applications:

Food industry

Using food-grade, BPA-free materials such as Polyethylene (PE or PET), plastic injection molding can produce food and beverage containers, filtration parts, overcaps, and conveyor system parts.

Medical devices

Stricter than food safety standards, medical equipment and devices must be manufactured with FDA or medical-grade resins to reduce patient risk. Products such as testing kits to dental X-ray components are usually lightweight and require precision. Other medical devices include IV connectors, pumps, test tubes, forceps, syringes, catheters, and scalpels.

Automotive Industry

Being able to mass produce complex parts, plastic injection molding can create components such as engine parts, connectors, sensors, bumpers, door panels, and seating components.

Electronics

Plastic injection molding matches technological complexity with automated machinery and precision. Molded parts include cases for electronic devices, USB connectors, HDMI connectors, and LEDs

Food industry

Plastic injection molding uses less energy to produce complex parts while meeting demands in short lead times. This helps with producing accessories, pipes, window profiles, foam panels, and insulation boards.

Tooling

Plastic injection molding produces molds, dies, fixtures, and rapid prototypes of any components for accurate testing.
