# LSR Overmolded Metal Handle Grip Sleeve
*Manufactured by 橡楚（湖北）橡胶有限公司*

LSR Overmolded Metal Handle Grip Sleeve is a custom-molded component that combines a structural metal core with a durable liquid silicone rubber (LSR) outer coating, designed to improve grip comfort, vibration dampening, and corrosion protection for handheld tools, equipment handles, and industrial fixtures.
At 橡楚（湖北）橡胶有限公司, located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, we produce these overmolded sleeves using food-contact and industrial-grade virgin LSR materials, paired with precision overmolding processes that create a permanent, non-delaminating bond between the silicone outer layer and metal inner core. Unlike slip-on rubber grips that shift, crack, or peel over time, our overmolded design delivers consistent long-term performance even in harsh temperature, chemical, and high-wear environments.
Our core selling points include: permanent bonding between LSR and metal, customizable hardness and dimensions for any application, compliance with standard material safety requirements, and resistance to extreme temperatures and common industrial contaminants.

Our overmolding process adheres to the following controlled production parameters to ensure consistent quality:
---
Our production process combines mechanical surface pre-treatment of the metal core with chemical priming that creates a molecular-level bond between LSR and metal. Unlike assembled or glued grips, our overmolded sleeves will not separate, peel, or shift even after years of repeated use, heavy loading, or exposure to temperature fluctuations. This eliminates maintenance and replacement costs associated with loose slip-on grips.
LSR has a natural soft, non-slip texture that stays comfortable even during prolonged handheld use. It effectively absorbs up to 30% more operational vibration than rigid plastic or solid rubber grips, reducing user fatigue and lowering the risk of repetitive strain injury (RSI) for workers using hand tools or industrial equipment daily. The non-porous surface of LSR also resists dirt and sweat buildup, keeping the grip clean and non-slip in wet or oily conditions.
Our LSR material maintains consistent performance across a far wider temperature range than thermoplastic rubber (TPR) or natural rubber grips. It remains flexible in sub-zero temperatures down to -40°C and does not soften, degrade, or leach chemicals at continuous temperatures up to 200°C, making it suitable for both cold outdoor industrial applications and high-heat equipment use. It also resists corrosion of the inner metal core by blocking moisture, oils, and other corrosive contaminants from reaching the metal surface.
We produce LSR overmolded metal handle grip sleeves in custom dimensions, hardness grades, and surface finishes to match your specific product design requirements. We can add texture, grooves, ergonomic contours, or color coding to the LSR outer layer to meet functional or branding needs, and work with customer-specified metal core materials to match required load-bearing capacities.

Select the LSR outer layer hardness based on your application needs:
All our LSR overmolded metal handle grip sleeves are custom-manufactured to match your required dimensions. We accept specifications for inner metal core diameter, outer LSR diameter, total length, and end contour to integrate directly into your finished product. Standard stock sizes are not offered, as each sleeve is produced to match customer design requirements.
We offer two standard material grades:
