Plastic Chair Mould Manufacturers

What is the production process of plastic chair mold? How to do injection molding?

The production process of plastic chair mold generally includes the following steps:

Mold design and manufacturing: The design of the mold needs to be carried out according to the size, shape, and wall thickness of the product. Molds are usually made of metal materials, such as steel, aluminum alloy, etc. Manufacturing molds requires processes such as CNC machining, milling, drilling, and grinding.

Plastic pellet processing: Plastic pellets are heated and pressurized to make them into a molten state to form a plastic melt.

Mold Preheating: The mold is heated to an appropriate temperature to ensure that the plastic material can fully flow and fill the mold cavity when injected.

Injection molding: inject the heated plastic melt into the cavity of the mold, and after the plastic cools and solidifies, the molded plastic chair can be taken out.

Cooling and demoulding: Take the formed plastic chair out of the mold, and then place it in a cooling device for cooling to ensure the quality and performance of the product. After cooling, the finished product can be ejected from the mold.

In the injection molding process, factors such as temperature, pressure, flow rate, and cooling rate of the plastic melt need to be considered to ensure that the plastic material can fully flow and fill the mold cavity while avoiding product defects such as warping, deformation, and air bubbles wait. To ensure product quality and stability, injection molding requires multiple trials and optimizations.

How does the cost of producing a plastic chair using plastic chair mould compare to other manufacturing methods?

Compared to other manufacturing methods, the cost of producing plastic chairs using molds is generally lower for several reasons:

1. The manufacturing and production process of plastic molds is relatively simple, and the cost of mold manufacturing is usually low.

2. The injection molding process has the advantages of high efficiency, rapidity, and automation, which can greatly increase production efficiency and output, thereby reducing production costs.

3. Compared with other materials, the price of plastic raw materials is lower, and the material processing process is relatively simple, which further reduces the production cost.

4. There is no need to use other special equipment in the production process of plastic chairs, only injection molding machines and plastic molds are required, so the production process is simple and the operating cost is relatively low.
