Frequently Asked Questions

What is Mold Flow Analysis and why is it important?

Moldflow analysis is a simulation tool used to predict how molten plastic will flow inside a mold. It helps identify potential defects like air traps, weld lines, and sink marks before manufacturing, reducing costly mold modifications and production delays.

Do you provide DFM reports with mold design?

Yes, every custom mold design includes a comprehensive Design for Manufacturability (DFM) report. This report highlights potential issues and provides recommendations to improve part quality and reduce production costs.

What types of molds can you design and build?

We specialize in overmold, 2K, insert, automated, and appliance molds. Our team has experience across consumer electronics, automotive, medical, and industrial applications.

How long does it take to complete a mold project?

Timeline varies based on complexity, but typical projects range from 4 to 8 weeks. Moldflow analysis is delivered within 3 business days. We provide detailed project schedules upon confirmation.
