How Much Does Injection Molding Cost?

Injection molding is an amazing manufacturing process to create high-quality, mass-produced plastic parts. But for those new to the process, the initial cost can be intimidating. In this article, the professionals at Buzz Trading shed light on the factors affecting injection molding costs, giving you a better understanding of the price involved in bringing plastic parts to life.

Injection Molding Costs: There is No Set Price

The truth is there’s no one-size-fits-all amount when it comes to injection molding costs. Prices can vary widely, ranging from a few hundred rands for simple, low-volume molds to upwards of thousands for complex, high-production molds. To give you a better idea, let’s explore the factors that influence the final cost:

  • Mold Complexity:Simple designs with minimal features will naturally cost less to produce compared to intricate designs with tight tolerances and special features.
  • Mold Material: The most common material for injection molds is steel, but the specific type of steel used can impact the cost. Higher-grade steel offers greater durability for high-volume production runs but comes at a premium. Thankfully, at Buzz Trading we use 3D-printed molds which are much lighter on the pocket.
  • Number of Cavities: A single-cavity mold produces one part per cycle, while a multi-cavity mold can produce multiple parts simultaneously. While multi-cavity molds have a higher upfront cost, the cost per part reduces significantly as production scales up.

Injection Mold Cost Calculator: A Helpful Tool, but Not a Crystal Ball

Several online injection mold cost calculators can provide a rough estimate based on some basic parameters. These tools can be a valuable starting point, but they shouldn’t be considered as set in stone. The true cost will depend on the specific details of your project, which is why consulting with a reputable injection molding company is crucial.

Injection Molding Costs in South Africa

While it’s difficult to provide exact figures due to the ever-changing economic landscape, injection mold costs in South Africa generally follow the same trends as the global market. However, it’s advisable to get quotes from local mold makers to get a more accurate picture of the pricing specific to your project and the current market conditions.

Injection Molding Cost Per Kg: Not Always the Best Metric

It might be tempting to compare injection molding costs based on the price per kilogram of plastic used. However, this approach doesn’t consider the significant role mold complexity plays in the overall cost. A small, intricate mold might use less plastic but have a higher overall cost due to its design.

Beyond the Mold: Additional Costs to Consider

When calculating the total cost of injection molding, it’s important to factor in additional expenses beyond the mold itself. These might include:

  • Per-unit molding costs: These can include factors like machine setup time, labour costs, and machine running costs.
  • Finishing costs: Secondary processes like painting, plating, or assembly might add to the final cost per part.
