What is custom injection molding?

It is a way of making plastic products by melting plastic and pouring it into a mold to form a desired shape. The process is called “custom” because the mold and the product design are made specifically for a customer’s unique requirements.

Injection moulding processes step by step

  1. Product development
  2. Prototype to check the part
  3. Mold Design
  4. Tooling Manufacturing
  5. Material and Master Color Preparation
  6. Clamping the mold on the injection molding machine
  7. Injection of the molten resin into the mold
  8. Cooling the part in the mold
  9. Ejection of the part
  10. Inspection of the plastic part
  11. Packaging the part

Advantages

  • Automation and high production rate
  • Material and color flexibility
  • Plastic material can be recycled, and minimal waste
  • Part cost is low for high-volume production
  • Consistent quality and high tolerance precision
  • Flexibility design, part can be complex shapes

Disdvantages

  • Initial tooling cost is high
  • Not economical for 1 to 100 pc

Tolerance

The tolerance for injection molded parts includes dimensional tolerance, part weight tolerance, and surface finish tolerance. It mainly depends on the part design, plastic material, tooling design, mold making, and injection molding manufacturing process.

Plastic Part Cost

Plastic part cost=raw material cost + injection molding manufacturing cost + package cost

The price of custom injection molding can change a lot based on factors such as part design, plastic material, part volume, mold cavity number, molding cycle time, molding machine size, and package.
