Just send us your drawing, 3D model, or even a rough sketch with dimensions — we’ll handle the rest. What type of silicone do you use for the plugs? + Our silicone plugs are made from high-quality food-grade or medical-grade silicone, compliant with FDA, LFGB, and REACH standards.

We also offer PVC or TPE alternatives if needed. Are your silicone plugs durable for industrial or electronic use? + Absolutely. Our plugs are heat-resistant (-40°C to +250°C), waterproof, and highly resilient. They're suitable for USB ports, battery compartments, power stations, medical equipment, and other sensitive electronic interfaces. Can I add a logo or marking to the silicone plug? + What if I only have a rough idea or drawing? + No problem! Our design team can help transform your rough sketch, hand-drawn image, or idea into a finished 3D model suitable for mold making and mass production. We provide DFM (Design for Manufacturing) support at no extra charge. What payment methods do you accept? + We accept bank transfers (T/T), PayPal, and Alibaba Trade Assurance.
