Our Expert Mold Design
Efficiency-Driven Solutions
With over 30 years of experience in mold design using CAD software, Plast Fab specializes in precision 3D mold designs. Our services include detailed feasibility reports, mold flow analysis, and advanced design techniques like side core and multi-cavity molds. We focus on delivering high-quality parts through optimized runner systems.

Our Streamlined Mold Design Process




Step 1: Consultation We analyze your project requirements and plastic part design.
Step 2: DFM Design We optimize your part using Design for Manufacturability (DFM) principles for efficient injection molding.
Step 3: Mold Design Our engineers develop the technical plastic injection mold design, including hot runner, insert, or multi-cavity mold specifications.
Step 4: Review & Analysis We use design and mold flow analysis to simulate and verify the mold design before manufacturing.
FAQs
-
Q: What information do you need for a custom mold design quote?
A: For a custom mold design, we need your 3D part file (e.g., .STEP, .IGS), the plastic material you plan to use, the estimated annual production volume, and any specific surface finish requirements.
2. Q: What are the mold design basics I should know?
A: The most important mold design basics involve DFM (Design for Manufacturability). This means optimizing your part for molding by ensuring proper draft angles, uniform wall thickness, and appropriate gate locations to prevent defects and reduce costs.
3. Q: What's the difference between "mold design" and "mould design"?
​ A: They are the same! "Mold" is the American spelling, and "Mould" is the British spelling. We are experts in plastic mould design and mold design for clients worldwide.
4. Q: What's included in your mold design services?
A: Our mold design services include everything from initial concept to a production-ready design package. This includes DFM reports, mold flow analysis (on request), 3D mold assembly files, and 2D detail drawings for all components.
Comprehensive Plastic Part Design
Our process begins with your injection molding part design. We conduct a deep review of all design considerations in injection molding and design consideration for plastic molding. This DFM (Design for Manufacturability) step is a basic mold design fundamental that ensures your plastic part design for injection molding is optimized before tooling begins.
Advanced Mold Flow Analysis
We use design and molding simulation to perform a complete design and mold flow analysis of injection moulding. This critical step validates the injection mold gate design, perfects the plastic injection mold runner design, and optimizes the cooling design in mold injection for cycle time and part quality.
Advanced Mold Design Techniques
Our team excels at complex plastic injection mold design and molding die design. We are experts in hot runner mold design, insert mold design, injection mold slide design, 3 plate mold design, die casting mold design, and high-volume multi cavity mold design.
