In-House Manufacturing Capabilities Built for Custom Silicone Sleeves
We manufacture every custom silicone sleeve entirely in-house — from mold making to final packaging. This gives us direct control over quality, lead time, and consistency at every stage.
Compression Molding
Our compression molding lines are ideal for producing custom silicone sleeves in small to large volumes. This process works well for solid silicone parts with standard wall thickness, offering cost-effective tooling and a wide range of material and color options.
Co-Injection Silicone Molding
For complex or multi-material sleeve designs, we use co-injection molding to bond silicone directly onto plastic substrates or other components — ideal for integrated protective covers and overmolded handles.
Mold Design & Tooling
All molds are designed and manufactured in our own tooling workshop. We accept STEP, IGES, DWG formats or physical samples. In-house tooling means faster turnaround, lower costs, and full control over mold quality.
Prototype & Sample Production
Before committing to mass production, we provide physical prototypes and pre-production samples for your approval. Typical sampling lead time is 10–15 business days depending on mold complexity.
Quality Control & Clean Production
Multi-stage quality inspection from raw material testing to final appearance check. Our assembly and packaging lines operate in a dust-free environment to meet hygiene standards required by international buyers.
Surface Finishing & Branding
We offer silk screen printing, spray coating, oil finishing, and laser engraving to enhance product appearance and brand value. Every sleeve can be finished to match your exact visual and tactile requirements.
How Our Custom Silicone Sleeve OEM Process Works
Whether you're a first-time buyer or an experienced importer, our process is designed to be straightforward and low-friction.
