Company Introduction: YUYAO SHINER PLASTICS MANUFACTORY CO., LTD. leads the industry with expertise in crafting customized plastic solutions tailored to unique specifications.

Q: Are you a factory or trading company?
A: We proudly operate as a factory specializing in custom plastic injection molding, complemented by expertise in rubber parts and sophisticated after-treatment processes, including painting, printing, and assembly.
Q: What information is required for a quote on a custom plastic part?
A: Ideally, supply a 3D drawing in IGS/STEP/X-T format. However, equivalent information in other formats, such as a CAD drawing with weight details or physical samples, is also acceptable.
Additionally, please specify quantities needed and any special requirements, including painting, printing, or assembly.
Q: What materials can you work with?
A: We manufacture plastic parts using a range of materials, including PC, PP, ABS, Nylon, PA6, PA66, TPE, PVC, PBT, and Nylon with Glass Fiber. For rubber parts, we utilize NBR, Silicone, and more.
Q: I have a design for a custom part but am unfamiliar with the injection process. Can you offer advice on potential issues like shrinkage?
A: Absolutely. Our expert engineering team is adept in both design and injection feasibility. Upon receiving your drawing, we assess its suitability for injection molding and identify any design issues such as unnecessary material that could cause surface imperfections. We provide feedback to optimize your design before proceeding.
Q: What color options are available for my plastic part?
A: We can produce any color within the Pantone and RAL color systems, ensuring your product meets your exact visual specifications.
Q: What are your lead times for mold creation and production?
A: Typically, sample delivery takes 30-35 days post mold order. Production lead time varies from 2 to 8 weeks, contingent on order size.
Q: What is your mold life guarantee?
A: We offer a lifetime guarantee on molds. Generally, molds can sustain up to 500,000 shots before aging. Should production reach this level, we replace the mold at no extra cost to ensure continuous quality. Your initial mold investment covers all future production needs.
Q: Does the mold become our property after full payment?
A: Yes, upon full payment, the mold is your property. We securely store it to facilitate your production. It remains unchanged unless you request modifications. We guarantee it won't be used for third-party production without your consent.
Q: What are your delivery terms?
A: Our terms are EXW for air shipments and FOB Ningbo for sea shipments. As Ningbo is our closest port, we also offer coordinated shipping to other locations at negotiable rates.
