What is the production process of plastic furniture？

Do you know how to make the plastic furniture which we have meet everyday? For example, what machines and equipment are needed for plastic table, plastic chairs and so on. I believe most people are not clear.Here we want to talk about the production process of injection molding products.

The first step-drawing

Drawing is to describe the shape, style, structure, size and other details of the product through the computer. In the industry, it is called design and development of product 3D drawing. With the product 3D drawing, you can start the second step.

The second step is to make the hardware mold according to the 3D drawing. The mold needs to go through drawing review, modeling, material preparation, mold base processing, mold core processing, electrode processing, mold parts processing, inspection, assembly, trial mold, production, etc.

Take a look at the mold of this furniture chairs. The mold is divided into two parts: upper and lower mold.  Generally speaking, simple small products will choose set mold.  one product can be injected at a time, of course, the structure of the product the more complex, the more accessories, the larger the product size, the higher the cost of the mold.

The manufacture of plastic furniture is an injection molding process. First, let’s take a look at the true features of the so-called injection molding machine

Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould. Injection moulding can be performed with a host of materials mainly including metals  (for which the process is called die-casting ), confections, and most commonly thermoplastic and thermosetting polymers.

Injection moulding uses a special-purpose machine that has three parts: the injection unit, the mould and the clamp. Parts to be injection-moulded must be very carefully designed to facilitate the moulding process; the material used for the part, the desired shape and features of the part, the material of the mould, and the properties of the moulding machine must all be taken into account. The versatility of injection moulding is facilitated by this breadth of design considerations and possibilities.

The third step is to test the mold after the mold comes out TO test whether the mold is qualified or not, and whether the product injected reaches the expected effect. This requires the injection molding machine.

We know about the machinery, but what about the raw materials？

The raw material of plastic furniture：There are five varieties of general plastics  PE-polyethylene PP-polypropylene PVC-polyviny   PS-polystyrene  Acrylonitrile ABS.They are thermoplastics.

Engineering plastics generally refer to plastics that can withstand certain external forces, have good mechanical properties, high and low temperature resistance, good dimensional stability, and can be used as engineering structures, such as polyamide polysulfone, etc

In the process of injection molding, if you need to make color products, you can add the corresponding toner according to the color demand.Here are the colors created by adding different masterbatches of colors.
