Design for Manufacturability (DFM) Analysis: We critically analyze your part design to recommend improvements for moldability, strength, and aesthetics while significantly reducing costs.

Advanced CAD/CAE Engineering: Utilizing software like SolidWorks, UG/NX, and Autodesk Moldflow for precise 3D modeling, mold flow analysis, cooling simulation, and warpage prediction.

Mold Flow Analysis: Simulating the flow of plastic into the mold cavity to identify and correct potential issues like air traps, weld lines, and sink marks before cutting steel.

Precision Tooling Design: Designing robust mold structures including complex actions like sliders, lifters, and unscrewing mechanisms for sophisticated parts.

Material Selection Guidance: Advising on the best plastic resin for your application based on mechanical, thermal, and chemical requirements.

Injection Moulding Design

Our Proven Injection Moulding Design Process

Requirement & Concept Review: Deep-dive consultation to understand your part's function, cosmetics, and volume needs.

DFM Report & Quotation: We provide a detailed report with design improvement suggestions and a transparent quote.

Detailed Design & Simulation: Our engineers create the complete mold design and run simulations to validate performance.

Design Approval & Collaboration: We share the design with you for final review and approval, ensuring full alignment.

Seamless Handoff to Manufacturing: The approved design is seamlessly transferred to our precision machining team.

The Design Advantage

Manufacturing-Focused Design: Our designers work side-by-side with our mold makers. This integrated approach ensures designs are not only theoretically sound but also practical and efficient to machine and maintain.

Cost-Saving Focus: We identify opportunities for cost reduction without compromising quality—through optimal cavity numbers, simplified actions, and material efficiency.

20+ Years of Practical Knowledge: Our experience allows us to foresee potential production challenges that software alone cannot predict.

Collaborative Partnership: We see ourselves as an extension of your engineering team, committed to open communication and achieving your goals.

Injection Moulding Design Success Stories

Challenge 1: A part with thick walls causing sink marks. Our Solution: Redesigned rib structure and optimized gate location via mold flow analysis. Result: Perfect surface finish and reduced cycle time."

Challenge 2: A complex undercut requiring an expensive mold mechanism. Our Solution: Ingenious side-action design that simplified manufacturing. Result: 30% reduction in mold cost.

Don't let design flaws delay your project or increase costs. Leverage our injection moulding design expertise to get it right from the start. Upload your part drawings for a comprehensive DFM analysis and quote.
