How to calculate the cost price of plastic mould correctly?

Calculating the cost price of a plastic mold accurately requires a systematic approach and consideration of various factors. Here’s a step-by-step guide on how to calculate the cost price of a plastic mold correctly:

  1. Gather Design Information: Obtain detailed mold design information, including the number of cavities, part complexity, material requirements, surface finish, and any special features needed.
  2. Material Cost: Determine the material required to build the mold, such as the mold base material, core and cavity materials, and any additional components like inserts or sliders.
  3. Machining and Labor Costs: Estimate the machining and labor costs based on the mold’s complexity and the time required for various manufacturing processes, including milling, drilling, EDM, polishing, and assembly.
  4. Mold Size and Weight: Consider the size and weight of the mold, as larger and heavier molds may require more materials and additional handling, impacting the overall cost.
  5. Mold Lifetime and Maintenance: Estimate the expected number of cycles the mold can produce before requiring maintenance or replacement. This affects the amortization of the mold cost over the number of parts produced.
  6. Overhead and Profit: Include overhead costs, such as utilities, facility expenses, and administrative costs. Add a reasonable profit margin to ensure the mold manufacturer’s viability.
  7. Injection Molding Machine Compatibility: Consider any adaptations or modifications needed to ensure the mold is compatible with existing injection molding machines, which can add to the cost.
  8. Surface Finish and Texture: Account for additional costs associated with achieving specific surface finishes or textures on the molded parts.
  9. Miscellaneous Expenses: Include any other miscellaneous expenses, such as transportation, taxes, and handling fees.
  10. Compare Quotes: Request quotes from multiple mold manufacturers, as prices may vary based on their expertise, capabilities, and location. Compare the quotes to get a sense of the market price.
  11. Cost Analysis: Perform a comprehensive cost analysis to ensure all relevant factors have been considered, and the pricing aligns with the mold’s complexity and requirements.
  12. Cost Breakdown: Break down the overall cost into individual components, such as material cost, machining cost, labor cost, and overhead.

It’s important to work closely with experienced mold manufacturers or engineers during the cost calculation process to ensure accuracy and transparency. Additionally, having a clear understanding of the project’s specific requirements, production volume, and quality expectations will help in obtaining a more precise cost price for the plastic mold.

1、 Look at the mold structure. Is it a two plate mold? Three plate mold? Is hot glue duct used? If there are any special requirements, such as reset first, push plate push out, need for reaming, oil cylinder, etc., make sure the mold structure is clear first.
2、 Look at the material of the mold core. The size of the mold core and the difficulty of processing. For example, if there are many tendons and more electrodes are needed, the processing cost must be higher. There is also a difference between the front mold slider and the rear mold slider. The inclined jacking of the front formwork is different from that of the rear formwork.
3、 See the size of the mold base. Different brands are different.
4、 Look at the transportation cost. For example, if you want to export something to foreign countries, you should also add the costs of mold trial, sample delivery, taxes, etc.

Due to the complex production situation of plastic mold manufacturers, in actual work, various cost calculation methods are often used at the same time or in combination. This mainly depends on the production characteristics of plastic mold manufacturers, whose goal is to achieve both correct calculation of product costs and simplified cost accounting.

Calculating the cost price of plastic mould is an essential part of the plastic mould manufacturing process. Accurately calculating the cost price of plastic mould helps manufacturers make reasonable price quotations, control costs, and achieve sustainable development. Here are some key steps to calculate the cost price of plastic mould correctly.

  1. Material cost: The cost of raw materials is the most important factor in determining the cost price of plastic moulds. The cost of the raw material used to make the mould, such as steel, aluminum, or copper, can vary depending on the type, quality, and quantity required.
  2. Machining cost: Machining cost refers to the cost of turning, milling, drilling, and other processing operations. The complexity of the mould design and the precision required for the final product can significantly affect the machining cost.
  3. Labor cost: The cost of labor includes the salaries, wages, and benefits of the workers involved in the manufacturing process. The level of skill and experience required for the workers can affect the labor cost.
  4. Overhead cost: Overhead cost includes expenses such as rent, utilities, insurance, taxes, and depreciation of equipment. These costs are indirect and cannot be traced to a specific product or service, but they still need to be accounted for when calculating the cost price of plastic mould.
  5. Tooling cost: Tooling cost refers to the cost of producing the tools used in the plastic mould manufacturing process, such as jigs, fixtures, and molds.
  6. Design and engineering cost: The cost of designing and engineering the plastic mould is also an important factor. This cost includes the time and effort spent on designing and optimizing the mould for the specific product requirements.
  7. Quality control cost: Quality control cost refers to the cost of inspecting and testing the moulds to ensure they meet the required specifications and standards.

By taking into consideration the above factors and calculating the cost price of plastic moulds accurately, manufacturers can make informed decisions on pricing and cost management, which can ultimately lead to greater profitability and success in the market.
