Cost Model Overview

This document describes the User Guided Injection Molding cost model. With some notable differences, this Cost Model is based on the same calculations as the GCD-driven cost model for Injection Molding found in the Plastic Molding process group.

Important differences between user guided IM and the GCD-driven model include the following:

• The concept of undercuts replaces the analysis of slides and slide bundles used in the GCD-driven model.

• Tooling is always assumed to be constructed with a Standard Mold Base. Custom made tooling is not supported.

• Manual overrides of tool dimensions are not available in the user guided model.

In general, plastic molding costs are determined by aggregating material, labor, machine, and tooling costs.

This overview section summarizes assumptions and limitations of the following aspects of the model:

• General Process

• Part Geometry

• Materials and Stock Forms

• Machines

• Tooling
