Got Questions?

Frequently Asked Questions

Everything you need to know about our injection molding services and processes.

What is your minimum order quantity (MOQ)?

Our minimum order quantity is 100 pieces, making us ideal for both small batch production and large-scale manufacturing. This low MOQ allows you to test the market with minimal investment while maintaining high quality standards. We offer flexible scaling options as your production needs grow.

What materials do you work with?

We work with a comprehensive range of engineering-grade plastics sourced from top 500 brands, including:

•Commodity Plastics: PP, ABS, PE, HDPE
•Engineering Plastics: PC (Polycarbonate), PA6/PA66 (Nylon), POM (Delrin), Acrylic
•High-Performance: PEEK, UHMPE

All materials come with full inspection reports and can be customized with additives for UV resistance, flame retardancy, or enhanced durability based on your environmental requirements.

What is your typical lead time?

Lead times vary based on project complexity:

•Prototyping (3D Printing): 3-7 days
•Mold Development: 15-30 days depending on complexity
•Mass Production: 10-20 days after mold approval

We provide detailed project timelines during the quotation phase and offer expedited services for urgent requirements.

Do you offer design and engineering support?

Yes! Our experienced engineering team provides comprehensive design for manufacturability (DFM) analysis. We review your designs to optimize for injection molding, identify potential issues, reduce material costs, and improve production efficiency. We can also assist with 3D modeling, prototyping, and material selection to ensure your product meets both functional and cost requirements.

What quality control measures do you have in place?

Quality is our top priority. Our QC process includes:

•ISO 9001:2015 Certification: Systematic quality management
•Material Inspection: Full reports from certified suppliers
•In-Process Monitoring: 5+ years experienced QC personnel on each line
•ISO 2859 Sampling: Statistical quality control during production
•100% Outgoing Inspection: Every product checked before shipment
•Precision Testing: ±0.1mm dimensional accuracy verification

How do you protect intellectual property (IP)?

We take IP protection seriously. All client designs and technical information are strictly confidential. We offer Non-Disclosure Agreements (NDA) before any project discussion and maintain secure data management systems. Your molds remain your property, and we never share designs or specifications with third parties without explicit written consent.

Can you handle custom packaging and assembly?

Absolutely! As a one-stop manufacturer, we provide complete assembly services, custom logo printing (pad printing, laser engraving, hot stamping), and tailored packaging solutions. Whether you need individual poly bags, custom retail boxes, or bulk industrial packaging, we can accommodate your branding and logistics requirements to deliver market-ready products.
