FAQs
Clear answers to your engineering and manufacturing concerns.
What is your MOQ sample lead time for custom phone cases?
Our standard MOQ for mass production runs is 1,000 units per model/colorway. For early-stage brands launching new device models, we offer MUD (Master Unit Die) quick tooling, enabling functional T1 prototype samples in as fast as 10 to 14 business days so you can hit critical retail launch windows.
Do you provide product design services, and how are they charged?
Yes. We have an in-house engineering team providing end-to-end support, including 3D modeling, industrial design, and DFM structural optimization. While our design services are initially fee-based, we will fully refund the design fee if you choose to proceed with mold creation and production through us, giving you a cost-effective path from concept to market.
How long does it take from 3D drawings to getting physical samples?
For urgent projects, we utilize MUD quick tooling, which allows us to deliver the first batch of functional T1 samples in as fast as 10 to 14 days. Standard production tooling typically takes 3 to 5 weeks depending on the complexity of the case structure and surface finishes.
How do you ensure precise dimensions and drop-test reliability?
A phone case has to fit the device perfectly. We maintain mold machining tolerances within ±0.01 mm. Every batch undergoes strict in-house testing—including drop tests, button tactile feedback checks, and surface adhesion evaluations—before leaving our factory to ensure retail-ready quality.
How do you handle intellectual property (IP) protection?
We take your privacy very seriously. All design files and custom solutions are protected by strict Non-Disclosure Agreements (NDAs) signed prior to project review. Once tooling is fully paid, the mold and design ownership belong 100% to you.
Can we visit your production facilities in Dongguan?
We always welcome clients, partners, and auditors to visit our 40,000-square-meter manufacturing facility in Dongguan. Please contact our sales team in advance to schedule a guided tour of our cleanrooms, injection molding workshops, and testing labs.
