Company Introduction: Welcome to YUYAO SHINER PLASTICS MANUFACTORY CO., LTD, where tradition meets innovation in creating bespoke plastic injection molded parts.

Q: Are you a factory or trading company?
A: We are a dedicated factory, specializing in the artistry of custom plastic injection molding parts, complemented by our expertise in rubber components and advanced after-treatment processes like painting, printing, and assembly.
Q: What info do you need if I want to get a quote for a custom plastic part?
A: Ideally, we'd prefer a 3D drawing in IGS/STEP/X-T format. However, if other formats offer equivalent information, such as CAD drawings with weight details, or even samples, those are welcome as well.
Additionally, please specify related requirements such as the desired quantity and any special needs like painting, printing, or assembly for a comprehensive quote.
Q: What material can you handle?
A: Our capabilities span a broad spectrum of materials, including but not limited to PC, PP, ABS, Nylon, PA6, PA66, TPE, PVC, PBT, Nylon with Glass Fiber, Polycarbonate with Glass Fiber, AS, PS, as well as rubber materials like NBR and Silicone.
Q: I have a custom plastic part to make. I have the design but am unfamiliar with injection and unsure of potential shrinkage issues. Can you advise?
A: Absolutely. Our seasoned engineering team excels in both design and injection feasibility. Upon receiving your drawings, we will conduct a thorough feasibility assessment, identifying any design challenges, such as excessive material use that may lead to surface sink marks, ensuring optimized cost-efficiency and quality before proceeding.
Q: What colors can you achieve for my plastic part?
A: We can produce any color within the Pantone and RAL color system, providing you with a seamless match to your design vision.
Q: What's your lead time for mold and production?
A: Typically, sample delivery is within 30-35 days from mold order placement. The production lead time varies from 2 to 8 weeks, contingent on the order size.
Q: What's the mold life guarantee?
A: We offer a lifetime guarantee. Generally, a mold starts aging after about 500,000 shots, but if production reaches this benchmark, we will manufacture a new mold at no extra cost to ensure continuous stable production. You incur the mold cost just once, and we take full responsibility for all subsequent productions.
Q: Is the mold our property after full payment?
A: Yes, the mold is entirely your property after full payment. We maintain it in-house solely to serve your production needs. No changes occur without your express consent, and we do not replicate from this mold for third parties without your authorization.
Q: What are your delivery terms?
A: Our delivery terms are EXW for air shipments and FOB Ningbo for sea shipments. As Ningbo is our nearest port, we ensure a smooth shipping process, and can also coordinate deliveries to other locations worldwide with negotiable terms.
