Frequently Asked Questions

Find answers to common questions about our services and capabilities.

What materials do you work with for injection molding?

We work with a wide range of thermoplastics including ABS, PC, PP, PA (Nylon), POM (Acetal), PMMA (Acrylic), and various engineering plastics. We can also handle filled materials with glass fiber, minerals, or other additives.

What is your typical lead time for injection molds?

Lead times vary based on mold complexity, but typically range from 4-8 weeks for standard molds. Simpler molds can be completed in 3 weeks, while complex multi-cavity or hot runner molds may take 10-12 weeks.

Do you provide design for manufacturing (DFM) analysis?

Yes, we provide comprehensive DFM analysis for all projects. Our engineering team will review your design for moldability, suggest improvements for cost reduction, and identify potential manufacturing issues before tooling begins.

What quality certifications do you have?

We follow ISO 9001 quality management standards in our processes. While we may not have formal certification, our quality systems are built to meet or exceed ISO requirements with documented procedures, process controls, and continuous improvement practices.

Can you handle small production runs?

Absolutely. We specialize in low-volume production from 100 to 10,000 units. Our flexible manufacturing systems allow us to be cost-effective even at lower volumes, making us ideal for startups, pilot runs, and specialized components.
