Key Factors that Affect the Cost of Injection Molding

Price is often a major consideration when comparing companies that offer plastic injection molding in China. It’s normal for businesses to want to save money, but it’s also crucial to understand the things that can impact the cost of the service and why some parts are potentially more expensive to manufacture than others. With this information, businesses can make informed choices and work with the right injection molding partner.

Here are the key factors that can impact the cost of injection molding:

Design complexity

The more complex and intricate the part, the more challenging it is to configure the injection molding process. As such, the end product can become more expensive. The part’s surface finish, number of undercuts, and tolerances are among the aspects that can impact part complexity.

Resin

Resin can impact the price of the injection molding service based on its quality, color, availability, additives, and compounding. For instance, anything with abrasive compounds, like carbon, glass, or mineral, will need special molds, which can cost more.

Size

Plastic injection molding in China can cost more when building larger parts. A large component needs a same-sized mold, resulting in more material to manufacture and a higher price.

Mold material

Molds are crucial to the plastic injection molding process, and their material can significantly impact the cost of the service. Aluminum is less expensive and ideal for short production runs. However, low-volume production requires a durable material, which can be more expensive. That said, steel molds can be cost-effective because they last longer.

Mold base and cavities

The cost of the injection molding service can also depend on the mold base, the case that holds all components, cavities, and inserts. The mold’s construction and size are dependent on the mold’s size and material. In addition, more mold cavities can mean higher manufacturing costs because they require more tooling and labor.
