What is Silicone Sleeve？
Silicone Bottle Sleeve, also known as Silicone Glass Bottle Sleeve, Silicone Sleeve for Glass Bottle, Silicone Sleeve for Water Bottle. Bottles in our daily life are usually made of glass or stainless steel material, it's not convenient to hold when served hot drinks directly grasp, therefore silicone bottle sleeve shows up which is high temperature resistance and made from elastic silicone rubber by compression mold tooling.
Properties of Silicone Sleeve：
PROTECTIVE: Our custom-designed silicone sleeve protects your glass water bottle from bumps and scratches. Provides a non-slip gripping surface so you can safely transport your beverage wherever you go
NON-TOXIC: Made of high-quality 100% FDA food-grade silicone that is BPA/BPS-free, phthalate-free and contaminant-free
MADE TO FIT: Sleeve wraps around the bottom base of the glass to provide a padded surface
MINIMALIST DESIGN: A modern aesthetic makes this perfect for everyday life. From the office to the gym or your next weekend adventure, you can get your daily H2O without compromising style. This silicone sleeve gives you optimal gripping surface while allowing you to monitor your daily water intake
ECO-CONSCIOUS: By 2050 there will be more plastic in the ocean than fish. By choosing a glass water bottle you are actively helping to reduce single-use plastic bottle pollution and keeping our oceans clean.
Custom Silicone Sleeve Production Process：
Silicone sleeve for glass bottle uses high temperature vulcanized FDA Food Grade Silicone as the main raw material and produced by compression molding then moulding vulcanization:
1. Silicone Sleeve's design: Customers can offer the 3D & 2D design drawing for us, if don't have, let us know the basic dimension, our engineer can also help with the design.
2. Material Compression Moulding: Make a mold of silicone sleeve, after the mold is well-finished, prepare the raw FDA Food Grade Silicone, it includes raw FDA Food Grade Silicone mixing, color of improvement, calculate the weight of raw material, etc. Then make a preliminary silicone rubber sleeve by the silicone mold.
3. Surface symbols & logo treatment:
Silk Screen Printing: it means to add some symbols or logo on the surface by printing process, which can make the products more beautiful.
Logo Embossed on the surface, there are also many customers choose this kinds of production process, which means logo will be a little protruding from the silicone sleeves' surface as the followed picture shows.
Logo Debossed in the surface, generally customers seldom choose this production process, for debossed logo, the symbol will be get dirty easily & not easy to clear up.
4. Surface protective treatment: For shorter silicone sleeve, Matte Smooth Coating can make the silicone sleeve have a better tactile and anti-dust function. For full silicone sleeve, generally our customer will also require inside matte smooth coating (double sides). In this way, it will make the full glass bottle sleeve easy to "get on/off" from the bottle, so that users' can save the assembly time and will also have a better using experience.
5. Silicone protective covers’ flash-removed: because during the molding process, there will be some raw edges (flash) stick on products, so need to remove them by hand.
How to produce the Silicone Sleeve with Minimum Parting line?
1. Use good located pins, which will make the mold more accurate, and mold misalignment situation.
2. Choose harder mold steel material, If choose harder mold steel materials, good mold-making equipment and good mold assembly, parting line can also be minimum.
3. Mold surface treatment will also influence the parting line, generally, for products with high requirements about parting line, we recommend to do EDM after CNC process, and then choose matte smooth coating on the product surface, it not only can make the parting line smaller, also can make the grip has better tactile & anti-dust function.
