Examples of plastic injection molded parts

This assembled piece consists of around 20 individual pieces made from hard plastic to softer flexible material that is held together by metal screws. Some plastic parts have metal inserts that were molded into the piece during production to allow for rigid construction.

Babies have the problem of getting only a little food in their mouths. This baby bib adjusts sizes and catches extra food that inevitably falls. The bib is a thin flexible material allowing for easy manueverability and roll-up for travel.

Exterior antenna housing, mount, and shaft were all made to interlock and be installed on top of an RV or mobile home. This is only one of the many antennae.

Intricate angles on these teeth need to match-up for seamless use. This gear is part of an antenna array crank to be able to deploy the array when you reach your destination.

This crank shaft is engaged by a gear, whos main function is to translate rotational motion to linear motion via this molded helix. The aluminum shaft is for strength and cost, but an overmolded plastic helix is added for the motion.

A secure fit is needed for every screw. We can mold the initial screw and mold the mating threads of the screw. Thus fitting together with good dimensional accuracy.

Electrical components generally need good air flow for cooling during heavy loads/operations. Creating the necessary openings and rigidity was crucial. This is one solid piece that mounts to the frame.

This transformer case is meant to shield the outside world from the high power lines that are housed inside. The other benefit of this case is the ability to see through the shield to quickly identify if there are any issues inside without needing to turn-off the lines and unscrew the housing.

Sometimes you want your product's housing to really pop-out to entice your consumers. Who wouldn't want some realistic looking fangs?

Texture, lettering, and graphics can be added to any mold. This flexible piece has an added texture to give the part better asthetics and grip.

High visability products can help alert people of hazardous areas. These blockade lamps are used in traffic construction zones with an installed LED.

Most portable products need some sort of battery power. This battery housing is molded, then metal contacts are installed. This battery housing holds 8x AA batteries, so there are four on the front and four on the back.

Plastic parts can be made into virtually any color. This is a medical breathing aparatus filter housing, and the hose would attach to the thinner cylinder.

This customer was tired of working with cumbersome glasses on a daily basis to see close-up objects. Instead, they created these foldable glasses that could collapse to fit in their pocket with their lenses protected.

Battery cap clips can be made to attach and cover battery terminals. The added shielding prevents the contacts from discharging to other objects.

Creating a completely solid piece of plastic is avoided in plastic injection molding. On this design you can see all of the supporting structures that were implemented to give the part strength in different directions. This will also make the design have less material. This reduces the weight and cost per piece.

Tough compact designs with limited assembly can be made. This breathalyzer housing needed to be compact, portable, and easy to use. All of the necessary components were able to fit inside of this housing.

In your home you may have an in-sink garbage disposal that is rarely used. Placing this piece over the switch will help differentiate important switches from light switches nearby. This is also used as a safety feature for kids. This also has a memory hinge for continuous opening and closing.

Electronics in a corrosive or dirty environment need a housing to protect the electronics. This piece helped the customer protect the electronics from particulates, but allow various connectors to attach.

Keeping electronics secure and safe is one reason for creating a housing. Another reason this customer needed an electrical housing was to completely submerse their electronics in resin to hide their proprietary setup.

A majority of faceplates for wall outlets are made out of plastic. This faceplate requires a metal insert to hook-up coax cables. There are additional fitting tabs and holes to allow for screws to securly fit to the wall.

Plastic hand cuffs are a cheaper alternative to the traditional metal hand cuffs. These are made out of a more wear resistant material.

A product handle can serve as an electronic housing. This handle is for a medical breathing aparatus. The stand-offs help combine both halves with bolts.

This mouse has a rubber overmolded grip that magnifies text for disabled people.

Overmolding flexible material helps provide a softer contact to people's hands while the hard plastic keeps the slide tough.

Kids are never easy on objects. This pencil case holds their utensils and withstands repetitive dropping. All of the hinges and latches are the same material.

Many products require some assembly. If the product designer understands different methods of product creation, their overall part cost can be reduced. This product has three metal inserts molded into the part to help reduce secondary steps for assembly.

Support structures are added to this flexible pad to make them more rigid. Additionally grooves were added to give the part more grip.

Most phones today are inside some sort of protective case. This case is meant to wrap around your phone and stick out slightly to have the flexible material take the impact of the fall.
