Injection Molding Cost for Plastic Products in China

Are you interested in producing plastic products in China? Injection molding is a popular manufacturing method that can produce high-quality plastic products at a low cost. In this article, we will discuss the factors that affect injection molding cost in China and how you can optimize your production process to reduce costs.

Factors that Affect Injection Molding Cost in China

plastic resin - mold costs
plastic resin is one factor that determines mold costs
  1. Material Cost: The cost of raw materials is a significant factor in injection molding cost. Material costs can vary depending on the type of plastic resin used, the quality of the material, and the supplier. Our company has tight relationships with the right material supplier, that can help you reduce costs.
  2. Part Complexity: The more complex the plastic part, the higher the injection molding cost. Simple parts require less time and labor to manufacture and are therefore less expensive. Designing parts with simplicity in mind can help reduce injection molding costs.
  3. Quantity: The more parts you produce, the lower the cost per part. High volume production can help you reduce the injection molding cost per unit.
  4. Tooling Cost: Tooling is the process of creating molds for injection molding. Tooling costs can be high, but the cost per part decreases as the number of parts produced increases. Choosing a reliable tooling manufacturer can help you reduce tooling costs.

Optimizing Your Production Process

  1. Design for Manufacturing: Designing plastic parts with manufacturability in mind can help reduce injection molding cost. Simple designs, fewer cavities, and uniform wall thickness can all help reduce costs.
  2. Consider Automation: Automating the injection molding process can help reduce labor costs and increase production efficiency. Investing in automated equipment can help you achieve cost savings over time.
  3. Quality Control: Maintaining consistent quality control can help you reduce costs associated with waste and rework. Regular inspections and testing can help ensure that your parts meet specifications and reduce the need for costly rework.


Injection molding is an excellent manufacturing method for producing high-quality plastic products at a low cost per piece. By considering the factors that affect injection molding cost and optimizing your production process, you can achieve cost savings and produce quality products in China.
