Custom PVC USB Port Plug & Silicone Stopper Alternative – Dispensing Vulcanization Molding Process

In this video, you’ll see our dispensing vulcanization molding process used to manufacture custom PVC USB port plugs and components similar to silicone stoppers. The machine dispenses pink liquid PVC for custom logos and gray material for the plug body.

After precise multi-color dispensing, the mold is pre-cured in an oven, then closed manually and transferred into the compression machine for vulcanization. The result is a smooth, custom-fit plug that is perfect for sealing USB ports.
