At YONGLI, custom is our core. We started in 2009 as a dedicated silicone product workshop focused on innovation and quality. Today, while we offer a growing range of stock kitchenware—think trays, mats, lunch boxes, and more— our heart is still in building something just for you.

Looking to bring your own silicone kitchenware idea to life? Whether it's a baby-friendly lunch box, a uniquely shaped baking mat, or a logo-embossed ice tray, we’re here to help you shape your vision.

Wondering how custom silicone product development works?

Here’s how your idea becomes a real product▶

▛Discovery

We start with a conversation to learn about your brand, product goals, and any functional or aesthetic requirements.

Want to incorporate your logo? Have a specific shape or color in mind? Already have sketches or references?

Perfect—let’s talk.

▞Digital Renders

Our design team creates a 3D model of your product, complete with technical drawings and dimensions. You'll get to review and request any tweaks before we move forward.

▙Prototyping

We produce a silicone prototype for hands-on testing. This is where you can check fit, flexibility, and function— whether it's heat resistance, sealing performance, or kid-proof durability.

▜Tooling

Once the prototype and drawings are approved, we begin machining your production mold using precision CNC equipment.

This ensures clean edges, accurate sizing, and a smooth finish, every time.

▟Production

Time to pour! Our trained team prepares, casts, and cures your products in small or large batches—depending on your needs. Every step includes strict quality checks, from demolding to post-cure inspection.
