Small order quantity of Silicone Sleeves are acceptable
Each batch of materials are in line with the FDA certificate & RoHS requirements, do not have to worry about product quality problems.
Efficiency is the primary productivity, our production people can quickly produce large quantities of silica gel sleeve. ISO management system, quality and quantity guaranteed.
Silicone Bottle Sleeve can be divided into 2 types: full silicone sleeve which "wrap" the whole bottle and half silicone sleeve with shorter height. For these 2 kinds of water bottle sleeve, mold-making ways are also different:
Mold-making way 1 for shorter silicone sleeve: Cheap & Easier to make, also the production process is easy and without parting line.
Mold-making way 2 for full silicone sleeve: More Expensive & complicated, also the production efficiency is lower than way 1, for this kinds of mold-making way, there will be a parting line on the sleeve.
For the longer Silicone Sleeve, there will always be a parting line which will affect the products appearance.
Small parting line will make the Silicone Sleeve looks more beautiful with good quality, while big parting line will make the products looks like cheap products. So for many customers, the mostly esthetical issue is that they are concerned about the parting line. what will be the quality of that line and how big it will be. For the problem, we are confident that the products we made can abosolutely satisfied your needs, there are 5 points that affect the parting line:
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.
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.
Mold Steel Material, Located pins, Silicone sleeve surface matte smooth coating can also improve the parting line.
Fluorosilicone VS. Silicone for Gasket Seal Valve: Fluorosilicone (FVMQ) is an elastomer which likes silicone (VMQ) offering excellent extreme temperature stability along with greater resistant to fuel, oil, petroleum based fluid, non-polar solvents, acid and alkaline chemicals similar to fluorocarbon rubber (FKM, FPM, Viton). Fluorosilicone gasket, seal, o-ring and check valve are widely used.
