How do engineers calculate the price of plastic molds?
All kinds of tools and products used in our daily production and life, ranging from the base and body shell of the machine tool to the shell of a germ head screw, button and various household appliances, are closely related to the plastic mold. Now let's talk about how to calculate the price of plastic mold.

  1. First of all, it depends on the customer's requirements, because the requirements determine the selection of plastic mold materials and heat treatment process.
  2. Select a good material, draw a rough mold plan, and calculate the weight of the mold (calculate the price of the mold core material and mold base material) and the cost required for heat treatment. (Both are the weight of the wool embryo)
  3. According to the complexity of the mold core, the processing cost is generally 1.5~3:1 to the price of the mold core material and 1:1 to the processing cost of the mold base.
  4. The risk expense is 10% of the total price above.
  5. Tax
  6. The design cost is 10% of the total mold price.

Calculating the price of plastic molds can be a complex process that involves a variety of factors. It requires the expertise of experienced engineers who can take into account different variables to provide a comprehensive estimate.

The following are some of the key factors that engineers consider when calculating the price of plastic molds:

  1. Mold design: The complexity of the mold design is a major factor in determining the price. The more intricate the design, the more time and resources it takes to manufacture the mold.
  2. Material: The type of material used to make the mold affects the cost. Different materials have different properties and cost structures, which can impact the overall price of the mold.
  3. Quantity: The quantity of molds required can also influence the price. In general, the more molds required, the lower the unit price, as the fixed costs are spread across a larger number of units.
  4. Lead time: The lead time required to manufacture the mold can also impact the price. Shorter lead times generally result in higher prices, as the manufacturer may need to work overtime or expedite production to meet the deadline.
  5. Tolerances: The tolerances required for the mold can also impact the price. Tighter tolerances require more precise manufacturing processes, which can increase the cost.
  6. Surface finish: The surface finish required for the mold is another factor that can influence the price. Higher-quality surface finishes require more advanced machining techniques, which can increase the cost.
  7. Complexity of parts: The complexity of the parts that the mold will produce is another factor that can impact the price. More complex parts may require more advanced molding techniques, which can increase the cost.
  8. Additional services: Additional services such as mold testing, inspection, and maintenance can also affect the overall price of the mold.

In conclusion, calculating the price of plastic molds requires a thorough understanding of various factors, including mold design, material, quantity, lead time, tolerances, surface finish, complexity of parts, and additional services. An experienced engineer can provide a comprehensive estimate that takes all of these factors into account to ensure that the price is fair and competitive.
