Have you ever thought about your life if we never had plastic chairs? We would be stuck with the outdated wooden chairs that were uncomfortable to sit on. The heavy metal chairs were super difficult to move around, and transporting them was a huge task. 

Thanks to the invention of plastic chairs, we are blessed with lightweight, durable, and easily transportable chairs that come in an array of bright colors for us to choose from.

Plastic chairs hold a significant market share in the seating furniture industry. According to a report by Grand View Research, plastic chairs accounted for approximately 35% of the global seating furniture market in 2020

The modern globe requires convenience in all aspects of life. With plastic chair injection molding, that convenience is brought to a level greater than ever. 

Here comes the king of the injection molding industry!

YuanCheng Mold offers advantages over many conventional production methods. With plastic chair injection molding, the entire process is completed in a single step, significantly reducing manufacturing time. Let’s discuss plastic chair injection molding and how YuanCheng appears as the show’s star.

What is a plastic chair injection molding | A basic know-how

When we talk about plastic chair injection molding, it refers to transforming molten thermoplastic materials into complex shapes. 

It is the most common manufacturing technique for plastic chairs and other types of furniture. This method uses pressure instead of heat to create components with precise shapes and sizes that are often difficult or impossible to obtain in any other way.

This process results in a product with greater structural integrity and longer service life. With the help of advanced technology, it has become easier to create plastic chairs in large quantities with superior quality.

Injection molding is the most widely used manufacturing process for plastic chairs. According to Straits Research, the global plastic injection molding market is categorized by the types of raw materials and applications used. Polypropylene is the most significant contributor to raw materials’ market share. As of 2021, the market value was estimated to be USD 48,999 million.

Understanding the plastic chair molding process concept is easy, but what happens is a little complex. Every chair we see starts with a design that is then created with the help of plastic injection molding.

The whole process can be broken down into the following steps:

  • Designing the product and creating a prototype:

This involves defining the product’s shape, features, and dimension that needs to be manufactured. A 3D CAD model is created to ensure accuracy and precision in the design. 

This is followed by creating a prototype of the designed product with rapid prototyping technology, which helps verify its functionality and performance.

  • Designing the plastic injection mold:

Once the product’s design is finalized, the plastic injection mold is designed with the help of specialized software such as Pro/E, AutoCAD, and Mastercam. 

The mold consists of two parts, the injection side and the ejection side, designed with utmost precision to ensure the product is properly formed.

  • Manufacturing the plastic injection mold:

The plastic injection mold is constructed using high-grade steel. More intricate designs require specialized tools such as EDM (Electronic Discharge Machining), which is used to cut complex shapes accurately.

  • Collecting raw material for the plastic injection mold:

Once the mould is manufactured, the raw material must be collected for the plastic injection mould. The small granules of plastic, known as pellets, are ordered from the plastic supplier and loaded into a hopper. 

Different plastics require different quantities of material to be injected, which must be carefully considered during injection molding. HDPE, LDPE, ABS, and Polypropylene are some of the most common plastics used in injection molding.

  • Injection molding process:

Injection Molding is a process that forces molten plastic material into a mould cavity. The raw material is fed into a heated barrel, mixed, and moved into a mold by high pressure. This process begins with melting the plastic material and injecting it into a closed mould. 

The molten plastic is injected through a nozzle and forced into a mold cavity under high pressure. Then, the parts are allowed to cool before they are ejected from the mold and sent for trimming or other secondary operations.

Injection molding process allows highly specific parts to be produced with repeatable accuracy. It also offers the flexibility to use multiple plastic materials, colors, and textures in a single piece. The injection molding process is ideal for producing high volumes of identical parts with tight tolerances and superior surface finish quality.
