Injection Mould Design

Overview

Injection Mold Design & Manufacturing Course Training is a specialized mechanical engineering program that teaches how to design, develop, and manufacture molds used to produce plastic parts through the injection molding process.

The course integrates plastic product design, mold structure design, CAD modeling, and manufacturing methods, enabling students to design molds that can produce high-precision plastic components in mass production.

Month 1 : Engineering Drawing & Fundamentals
  • Technical Drawing Concepts
  • Engineering Standards & Conventions
  • GD&T (Geometric Dimensioning & Tolerancing) Basics
  • Manufacturing Symbols & Interpretation
  • Reading & Creating Industrial Drawings
Month 3 : Software & Practical Training
  • 2D & 3D CAD Modeling
  • Assembly Design & Detailing
  • Real-Time Industry Projects
  • Design Validation & Optimization
  • Final Project & Portfolio Development

Objective of Injection Mold Design & Manufacturing Training

The main objective of this course is to train engineers to:

  • Understand plastic injection molding technology
  • Design complete injection mold assemblies
  • Analyze plastic product manufacturability
  • Develop core and cavity structures
  • Prepare mold manufacturing drawings
  • Understand tool room manufacturing processes

After completing this course, students can work as Injection Mold Design Engineers or Tooling Engineers in plastic manufacturing industries.

What is Injection Moulding

Injection molding is a manufacturing process where molten plastic material is injected into a precision mold cavity under high pressure. The plastic cools and solidifies inside the mold to form the final product.

Injection molding machines are produced by companies such as:

  • ENGEL
  • Haitian International
  • ARBURG

This process is widely used to manufacture:

  • Automotive plastic parts
  • Consumer product housings
  • Electronic components
  • Medical plastic parts
  • Packaging components
