1) Injection molded pallet
Plastic material is introduced in pellet form into a "hopper" positioned at the top of a machine and forcing it along a horizontal chamber or "barrel" of an extruder by means of the rotation of a screw.
The plastic material is heated as it moves through the barrel so when it reaches an open cavity, it is a molten mass ready to assume the configuration of the mold.
The mold is closed and pressure is applied to form the pallet. Once the pallet is cooled and taken from the mold, it can be further processed into secondary operations such as painting, trimming or fastening.
2) Manipulator
A stationary (does not mean that nothing moves) movement assist device that is often equipped with end effectors for handling different types of loads. End effectors include all forms of grippers, forks, barrel grabs, etc. Manipulators counteract the weight of the load, rendering it almost weightless by way of hydraulic or pneumatic cylinders, or simply by way of counter weights and the exercising of very limited manual control. Most manipulators require manual actuation and control and are therefore manual assist devices. They are mounted to the floor, wall or ceiling. In some cases, manipulators are mounted to a fixed base plate and the entire unit can be moved via a trolley, cart or frok lift truck.
3) Injection molded container
Plastic material is introduced in pellet form into a "hopper" positioned at the top of a machine and forcing it along a horizontal chamber or "barrel" of an extruder by means of the rotation of a screw.
The plastic material is heated as it moves through the barrel so when it reaches an open cavity, it is a molten mass ready to assume the configuration of the mold.
The mold is closed and pressure is applied to form the container. Once the pallet is cooled and taken from the mold, it can be further processed into secondary operations such as painting, trimming or fastening.
4) Barrel
A cylindrically shaped vessel or container generally made from plastic, wood, aluminum or steel.
