Guidelines for Plastic Molding: Manufacturing and Processes

Plastic molding is an ideal solution to many manufacturing problems. From prototype design to mass production, many commonly used plastic parts are injection molded. For example, keyboards, mobile phone cases, and bottle caps can be made of different types of plastic injection molds for sale.

1. Common applications of plastic molding

One of the greatest advantages of this process is its incomparable unit price. After the initial investment in designing and creating molds, parts can be manufactured with high speed and efficiency.

2. The cost of plastic molding

The cost of an injection mold ranges from $1000 to $80000 or more, but the average costs are usually from $10 to $20000. When considering the total cost of a project, the most key factor is always the return on investment (ROI). This rate of return increases as the number of parts created increases. In other words, the larger your project, the faster you will recover the upfront cost of the mold. The main factors that determine the cost of your plastic molding project include:

① Complexity

② Materials

③ Part size

3. Plastic materials used in plastic molding

The most commonly used plastic materials for manufacturing are polypropylene, polyethylene, polyvinyl chloride, and acrylonitrile butadiene styrene (ABS). Because plastic materials can be selected to give different physical properties, it is important to know which materials should be used, depending on the application of your product. For example, some materials are resistant to high temperatures, while others are better in durability. And no matter what kind of products, there is a more suitable material for them.
