Silicone Protective Sleeve

Silicone Protective Sleeve also known as Silicone Case, Silicone Cover, Rubber Case and Water Bottle Silicone Sleeve.Silicone Sleeve is made of elastic silicone which is soft and flexible. Silicone Case usually be used for dust-proof of mobile phone, anti-scalding of the glass bottle and anti-falling of fragile part. Silicone Protective Sleeve is reusable and environment friendly. Sleeve can be made of silicone and rubber materials like EPDM, neoprene, NR, NBR and PTFE. 

Silicone Protective Sleeve

Silicone Protective Sleeve also known as Rubber Case, Silicone Cover, Rubber Sleeve and Water Bottle Silicone Sleeve. Silicone Sleeve is made of elastic silicone which is soft and flexible. Sleeve can be made of silicone rubber or elastic plastic materials like EPDM, neoprene, NR, NBR, PVC, TPR, TPU etc. Protective covers are usually used to prevent dust, drops, slips and burns. 

The most common protective covers in life are electronic equipment protective covers and water bottle protective covers. The protective case is usually formed by compression mold, and its surface is treated according to different uses and designs. The surface of the protective case is treated by a process such as silk screen painting, embossed logo or hydrographics transfer painting, etc.

Silicone Rubber Sleeve Prototype

  1. Small order quantity of silicone sleeve are acceptable;

  2. Raw materials are in line with the FDA certificates & RoHS requirements;

  3. High efficiency, 24-hour production. 

Silicone Protective Sleeve's Usage (just for reference):


Silicone Sleeve Surface Characters & Logo Treatment:

1. Silk Screen Painting

    Advantages: Not easy to fade, Light resistance

    Disadvantage: Can’t print gradient color, Suitable for simple color patterns


2. Roll Painting

    Advantage: Easy to print cylindrical protective case

    Disadvantage:Higher cost

3. Hydrographics Transfer Painting

   Advantages: Colorful pattern, Pattern individuation, High efficiency

   Disadvantages: Not wear resistant, Higher cost


4. Embossed Logo

    Embossed Logo: The logo on the surface of the mold is prominent, mold price is lower.

    Intaglio Logo: The logo on the surface of the mold is depressed, mold price is higher.

Silicone Sleeve of Two Different Parting Lines

Parting Line Influencing Factors:

  1. Mold's die-cutting edge: If didn't keep good maintainance of mold sharp edge, once it is damaged, the parting line will also become bigger.

  2. Mold surface treatment: It will also influence the parting line, generally, for products with high requirements about parting line, we recommend to do EDM process after CNC process to make the mold surface as texture surface.

  3. Mold Steel Material, Located pins, silicone sleeve surface matte smooth coating can also improve the parting line.


Long Sleeve: A separate movable plate needs to be placed in the middle of the upper and lower plates of the mold, and the parting line relatively obvious. Less efficient, more expensive, less perfect in appearance.

Short Sleeve: Only need the uper and lower plates. More efficient, cheaper, and perfect appearance.
