Silicone Handle Grip, also called Silicone Handle Sleeves & Cover, which made from elastomeric silicoen rubber materials by compression molding or injection molding, is designed to cover plastic or metal handle, like heat insulation, anti-slip, electric insulation, anti-oil or dust proof, also designed to improve handle grip touch feeling and friction etc.
Silicone Handle Grip & Sleeves, which is becoming more and more popular, not only high elastic, heat insulated and electric insulation, but also silicone materials is easy to vulcanize and matte smooth process.
Silicone Handle Grip's surface, generally need dermatoglyph finishing or sand blasting. After silicone handle grips product, some also need matte smooth process to improve handles grips touching feeling and anti-dust effects.
Before molde-making and Silicon Handle Grips production, silicone handle grips manufacturers not only care about the molded parting line or silicon rubber flashing, but also should think of silicon rubber handle grip parting lines positions and parting lines sizes telorances.
Elastomeric Rubber Handle Grip main materials: Silicone, Neoprene, NBR, EPDM, PU & Polyurethane etc, different handle cover materials have different properties and usage.
Elastomeric Rubber + Plastic & metal overmolded handle grips by compression molding, which should think about plastic handle locations, also should in view of plastic or metal which should heat resistance, the best up to 200oC. Like choose PBT or PBT+GF.
Liquid silicone Rubber (LSR) + Plastic & Metal overmolded handles grips by LSR injection molding, which is more precision, compare with silicone rubber + plastic & metal handle grips by silicone rubber compression mold tooling. And also, LSR + Metal & Plastic Handle Grips almost not consider plastic or metal thermal resistance, because down LSR injection mold plate temperatures is lower, which is about 140-160oC
