Frequently Asked Questions
Q
What is Liquid Silicone Rubber (LSR) and why is it ideal for mobile phone waterproof seals?
Liquid Silicone Rubber (LSR) is a high-purity, two-component platinum-cured silicone material processed through injection molding. It is ideal for mobile phone waterproof seals because it offers excellent compression set resistance, wide temperature tolerance (–55°C to +200°C), outstanding biocompatibility, and the ability to be molded into extremely precise micro-geometries — making it the preferred choice for high-performance consumer electronics sealing.
Q
What tolerances can Kingod achieve for custom silicone seals?
Kingod's advanced LSR injection molding processes achieve ultra-tight tolerances of ±0.05mm, which is critical for mobile phone sealing applications where even minor dimensional deviations can compromise IP waterproof ratings. Our automated quality control systems ensure every part meets your exact specifications consistently across high-volume production runs.
Q
Can Kingod produce overmolded silicone seals bonded to metal or plastic substrates?
Yes. Kingod specializes in complex overmolded components where silicone is directly bonded to plastic or metal substrates during the molding process. This eliminates the need for adhesives, improves bond integrity, and creates a robust, integrated seal assembly — commonly used in SIM tray seals, button assemblies, and display perimeter gaskets.
Q
How does Kingod protect my design confidentiality?
We take intellectual property protection very seriously. All customer designs, technical drawings, and project details are treated with strict confidentiality. We are happy to sign Non-Disclosure Agreements (NDAs) before any technical discussions begin, and our internal processes ensure that your proprietary information is never shared with third parties.
Q
What is the typical lead time for prototypes and mass production orders?
Prototype tooling lead times typically range from 2 to 4 weeks depending on part complexity, allowing you to perform functional testing before committing to full production tooling. Mass production lead times vary based on order volume and part specifications, but our team will provide a detailed timeline during the quotation stage to support your product launch schedule.
Q
How do I get started with a custom silicone seal project at Kingod?
Getting started is simple. Contact Kingod directly and share your technical drawings, design requirements, and application details. Our engineering team will review your project, provide Design for Manufacturability (DFM) feedback, recommend the most suitable silicone formulation, and prepare a comprehensive custom quote — all at no charge for the initial consultation.
