Injection Molding Parts Design

Injection Molding Parts Design Services

At TuohaiTech®, we bring together innovation, technology and decades of experience to solve the challenges of turning an entirely new product, concept or idea into a marketable solution. Our expert design team works closely with clients to optimize part designs for manufacturability, cost-effectiveness, and performance.

Our Design Process

We follow a systematic approach to ensure successful part design and development:

1. Concept Analysis: Review your product requirements, application, and performance needs
2. DFM Review: Design for Manufacturability analysis to optimize for injection molding
3. 3D Modeling: Create detailed 3D CAD models using SolidWorks, Pro/E, or UG
4. Mold Flow Analysis: Simulate material flow to identify and eliminate potential issues
5. Prototyping: Rapid prototyping for design validation and testing
6. Design Optimization: Refine design based on prototyping results
7. Production Release: Finalize design and prepare for mold manufacturing

Design for Manufacturability (DFM)

Our DFM analysis ensures your part can be produced efficiently and cost-effectively:

• Wall Thickness Optimization: Uniform walls prevent warpage and sink marks
• Draft Angle Analysis: Ensure proper part ejection from mold
• Rib Design: Add strength without increasing wall thickness
• Undercut Elimination: Redesign to avoid costly side actions
• Gate Location Optimization: Minimize witness lines and flow marks
• Tolerance Analysis: Set realistic tolerances for cost-effective production

Advanced Mold Flow Analysis

We use state-of-the-art mold flow simulation software to predict and optimize the molding process:

• Fill Analysis: Predict material flow and identify potential short shots
• Pack Analysis: Optimize packing pressure to prevent sink marks
• Cooling Analysis: Design efficient cooling systems for consistent quality
• Warp Analysis: Predict and minimize part warpage
• Fiber Orientation: Analyze fiber-filled materials for optimal strength
• Gate Optimization: Determine best gate location and size
