Top 5 Types of Plastic Moulding Techniques with WeyMould

The demand for the best Plastic Molding Company is undoubtedly on a rise today. While there are huge competitors in the market, WeyMould has built and secured its place amongst the most prominent list over the years. Being one of the leading groups in the plastic molding industry; WeyMould has an experience of over 10 years in the service. Furthermore, it always lies in the client’s interest in the detailing of the required product molding. Go on, and check out this simple guide that tells about the types of plastic molding and how it works.

1. Injection Molding

In Injection molding, custom plastic parts are made by injecting molten plastic material at high pressure into another metal mold. Afterward, once the molten plastic is injected into the mold, the mold is cooled and opened to reveal a solid plastic object. These also include PVC Pipe Fitting Injection Molding Machine, steel or aluminum tools, etc.

2. Compression Molding

As the name suggests in compression molding, heated plastic material is placed into a heated mold, and further compressed into a particular shape. This is an example of PET Preform Mould, in which the plastic is compressed into the right shape, and the heating secures that the plastic holds the greatest strength. Finally, at last of this process involves cooling, trimming, and then removing the plastic part from the mold.

3. Blow Molding

During the blow molding procedure, a hollow, thin-walled, and custom plastic parts are created. It is mainly used for producing products with consistent thickness, keeping the shape important. Blow molding machines work by heating the plastic and inject air blowing up the hot plastic like a balloon. The plastic then expands and turns into a mold. Further, the whole structure is cooled and hardened, and the part is ejected.

4. Extrusion Molding

Extrusion molding is the same as injection molding. However, in this one, a long continuous shape is produced and a die is used instead of a mold. Extruded parts of plastic are created by squeezing hot raw material through a custom die. In this process, the melted plastic extrudes directly into a die. Afterward, the final product is made.

5. Thermoforming

In this manufacturing process called thermoforming, a plastic sheet called thermoplastic is heated to a flexible forming temperature and it is created into a specific shape in a mold. Finally, it is trimmed to create a usable product. There is a wide variety of thermoplastic that comes in a variety of materials, colors, finishes, and thickness. In thermoforming, a variety of different types of molds are used and processed to achieve the final product. Thermoforming requires low pressures, and the molds can be produced within a reasonable budget using inexpensive materials.
