4.  Ways of Manufacturing Automotive Plastic Parts

Some of the most common manufacturing processes include:

Injection Molding Automotive Plastic Parts

Injection molding is a process that involves the use of plastic material in raw form, the mold and the injection molding machine.

During this process, the plastic material passes through the machine for the melting process.

The material in molten form then undergoes cooling and solidification hence forming the specific automotive parts.

injection molding

Injection molding involves the following processes;-

Clamping

During the clamping process, there is the closure of the two parts that make the halves of the mold.

The closing is done by the hydraulic clamping unit.

Where the halves clamp together by allowing one halve to slide on the other,

While both attach to the clamping machine.

The clamping unit pushes the halves together while exerting force so as to ensure the molds are together while injecting the material.

Injection

Here raw plastics in pellets form are put in the injection molding machine, where they are in a position to reach the molds.

During injection process pressure and heat enables melting of the material. The material in its molten form gets injected into molds.

After the injection of the molten plastic into the molds, there is pressure packs buildup that holds the material also known as the shot.

Cooling.

The existing molten plastic in the mold gets into contact with the interior surfaces of the mold and starts to cool.

In the process of cooling, the plastic then solidifies in the specific part of design.

Ejection

Ejection process applies where an ejection system ejects the cooled part that has an attachment with the rear half of the mold.

There is an application of a mechanism in which it uses force to push out the cooled part out of the mold.

Extruding Automotive Plastic Parts

Plastic extrusion is basically a continuous process.

Plastic undergoes heating then moves to a hot chamber by the aid of a screw.

The plastic then forcefully passes through a die creating a final shape of the part. Lastly, there is the cooling and cutting to right sizes.

extrusion molding

Vacuum Forming Automotive Plastic Parts

This is a type of thermoforming method , that uses only one mold in the manufacturing of plastic shaping.

Here, a plastic piece undergoes heating and then there is the pulling of a single mold through the process of suction.

vaccum forming

Vacuum forming  is a very flexible and affordable method of shaping plastic parts.

Thermoforming Automotive Plastic Parts

This is a type of manufacturing where there is the heating of a plastic sheet until it becomes pliable.

Thereafter, follows the contouring and shaping by use of a mold, hence creation of a final part.

thermoforming

CNC Machining Automotive Plastic Parts

CNC machining is a process in which there is the removal of the material using a spinning tool together with a fixed part.

The output of the process is of high quality.

Blow Molding Automotive

Blow molding is a process involving the melting of the material, homogenizing, extruding, molding cooling, and the ejection process.

Blow molding

Involves the following steps.

Plastic Resin Feeding.

This is the first step ,where there is conveyance of  plastic pellets into the extrusion hopper machine.

Melting.

The plastic resin inside the extrusion machine undergoes melting by kneading and heating in a continuous process.

Parison Extrusion.

The process prepares perform for insulation.

Here, there is the extrusion of plastic into a perform mold.

Clamping.

Here, a split die captures the parison or perform.

Then there is the sealing of its ends leaving one hole for the injection of compressed air.

Inflation.

The plastic material now takes its form.

Rotation Molding Automotive Parts

The production of large objects with hollows, through the creation of parts having close to uniform thickness of the wall.
