FAQs About Injection Molding Service

We have a minimum order  qty of 500 pcs. For orders below this quantity, we recommend considering 3D printing or vacuum casting, as these methods are often more cost-effective while still meeting your tolerance requirements.

Once an order is placed, the process begins with mold design and creation, which typically takes around 3-5 days. After the mold is ready, it usually takes an additional 3-5 days to produce the molded parts. This timeline ensures that each step, from designing to final production, is handled with precision and attention to detail, guaranteeing high-quality results for your project.

The cost of our services is influenced by various factors, including the size of the components, the complexity of the mold, the number of cavities, the type of material used, and any post-processing requirements. To ensure accurate pricing, we analyze these factors in detail on our platform before providing a quote. This comprehensive evaluation allows us to offer competitive and tailored pricing for each project, ensuring that you receive the best value for your investment.
