Frequently Asked Questions
Clear answers to your engineering and manufacturing concerns.
What is your Minimum Order Quantity (MOQ) and primary business model?
We specialize in custom plastic injection molding and mold fabrication (OEM/ODM). Our standard MOQ for mass production is 1,000 units. For low-volume prototyping or bridge production, we offer flexible pilot batches via MUD quick tooling. Note: We do not supply off-the-shelf public stock molds.
What details are required to get an accurate quote and DFM analysis?
To help our engineering team provide a precise quote and Design for Manufacturability (DFM) review, please provide:
1) 3D CAD files in .STP / .STEP or .X_T formats;
2) Material requirements (e.g., PC, ABS, TPU, Silicone, or required surface texture);
3) Estimated order volume and timeline.
What is the typical lead time for mold fabrication and T1 samples?
For MUD Quick Tooling, first-off samples (T1) can be delivered in as fast as 10 to 14 days. Standard production tooling typically takes 3 to 5 weeks, depending on mold complexity, cavity count, and surface finishing requirements.
How does YG TECH protect our designs and intellectual property (IP)?
We strictly safeguard your assets. We execute a mutual Non-Disclosure Agreement (NDA) before receiving any proprietary CAD models. Furthermore, 100% legal ownership of the mold belongs to you once full tooling payment is completed.
What manufacturing tolerances and facility certifications do you hold?
Our standard machining tolerance is ±0.01 mm (ultra-precision up to ±0.005 mm). Our facility operates under ISO 9001:2015, ISO 14001:2015, and ISO 13485:2016 (Medical Devices), featuring an ISO Class 8 cleanroom and 140+ injection presses ranging from 50T to 800T.
What are your standard payment and international delivery terms?
Standard tooling terms are 50% deposit, 30% upon T0/T1 sample dispatch, and 20% upon final sample approval. Production runs require 30% deposit and 70% balance prior to shipment. We support international freight terms including EXW, FOB, CIF, and DDP (Door-to-Door).
