Frequently Asked Questions (FAQs)
How do I evaluate the quality of a plastic injection moulds manufacturer?
Check the manufacturer’s certifications (like ISO 9001), client references, product samples, and case studies. Visit their facility if possible, review their quality control processes, and ensure they use robust materials and advanced technology.
What minimum order quantity (MOQ) do manufacturers usually require?
MOQs can vary widely based on the complexity and size of the mould. Some factories accept small orders for prototypes, while others focus on large production runs. Always discuss MOQs upfront to ensure the manufacturer matches your project needs.
How long does it typically take to get a custom mould made?
The entire process—from design approval to finished mould—can take 4 to 12 weeks, depending on the mould’s complexity, size, and the manufacturer’s schedule. Simple projects may be quicker, while intricate moulds may take longer.
What factors influence the cost of plastic injection moulds?
Costs depend on the mould size, complexity, materials used (e.g., steel vs. aluminum), required tolerances, and the expected production volume. Extra features like inserts, surface finishes, or rapid cooling channels also affect pricing.
How can I ensure good communication with an overseas mould manufacturer?
Choose manufacturers with English-speaking sales or technical teams, prompt replies, and clear communication channels. Use video calls, share detailed drawings, and confirm all agreements in writing to avoid misunderstandings.
