Our Food Grade Non-slip Kitchen Utensil Overmolding Parts LSR Handle Grip Accessories are high-performance liquid silicone rubber (LSR) components designed to enhance ergonomics, safety, and durability for a wide range of kitchen hand tools. As a trusted overmolding solution, these grips are engineered to bond seamlessly with rigid substrate materials including PP, ABS, stainless steel, and aluminum, eliminating the risk of delamination even after years of heavy use.
The core selling points of this product lie in its industry-leading food contact compliance, exceptional slip resistance in both dry and wet conditions, and extreme temperature tolerance that supports daily kitchen use from frozen food prep to high-heat cooking scenarios. Unlike generic thermoplastic rubber (TPR) or PVC grips, our LSR handle grips do not leach harmful chemicals, fade, or become sticky after prolonged exposure to oil, detergent, or high temperatures, making them a superior choice for premium kitchen utensil brands and home cookware manufacturers.
Each grip is precision-molded to a tight tolerance of ±0.02mm, ensuring a consistent, gap-free fit with your utensil substrate during assembly. Custom texture options including diamond knurling, wavy ribbing, and micro-convex patterns are available to tailor grip strength and aesthetic design to your brand’s requirements, with no additional tooling costs for standard texture modifications.
All LSR handle grips are formulated from 100% food-grade liquid silicone rubber that meets global food contact safety standards, with no added plasticizers, BPA, phthalates, or heavy metals. Key material properties include:
The LSR grips are engineered to withstand the demanding conditions of daily kitchen use, with the following physical performance metrics validated via third-party lab testing:
These LSR grips are designed for high-volume overmolding production, with optimized process parameters to reduce manufacturing costs and improve yield:
Unlike TPE or TPR grips that lose friction when exposed to water or cooking oil, our LSR grips maintain a coefficient of friction above 0.75 even in soapy, greasy conditions. This reduces the risk of utensil slippage during high-heat cooking or wet food prep, preventing scalds and food waste. Independent testing shows our grips reduce slip-related accidents by 82% compared to uncoated stainless steel handles and 47% compared to TPR-coated handles.
The high-performance LSR formulation resists compression set, discoloration, and material degradation even after 10,000+ wash cycles in residential and commercial dishwashers. Unlike PVC grips that become brittle after 1–2 years of use, our LSR grips retain their elasticity, texture, and slip resistance for the entire service life of the utensil, supporting 10+ year product warranties for premium cookware lines.
Every batch of LSR material undergoes third-party testing to ensure compliance with global food safety regulations, with no leachable harmful substances even after 24 hours of contact with acidic food (pH 3.0) or high-fat food (100°C oil). The grips are also tasteless and odorless, so they will not transfer flavors to food even when used for stirring hot soups or handling raw ingredients.
We offer fully customizable texture, color, and embossed logo options with no minimum order quantity surcharge for standard modifications. Pantone color matching is available with a tolerance of ΔE ≤2, ensuring your grips align perfectly with your brand’s visual identity. Embossed or debossed logos up to 0.3mm deep can be integrated directly into the mold, eliminating the need for secondary printing or labeling that wears off over time.
These LSR handle grip accessories are suitable for a wide range of kitchen utensil categories, including:
For utensils intended for users with arthritis or limited hand strength, we recommend our 30A Shore A hardness option with micro-rib texture, which reduces required grip force by 30% compared to standard hard plastic handles.
Choose the appropriate Shore A hardness based on your use case:
Custom hardness values between 20A and 70A are available for orders of 10,000 units or more.
Our standard grip sizes are compatible with most common utensil handle dimensions, with custom sizes available for unique designs:
All grips are molded to a tolerance of ±0.02mm to ensure a press-fit assembly without the need for adhesive, reducing your production costs. For overmolding directly onto substrates during production, we provide free DFM (design for manufacturing) analysis to optimize your handle geometry for maximum adhesion.
We offer three LSR material grades to match your product positioning and compliance requirements:
We implement a strict multi-stage quality control process to ensure every batch of LSR handle grips meets performance and safety requirements:
All products come with a 2-year quality warranty against manufacturing defects, including delamination, discoloration, and loss of slip resistance under normal use. For custom orders, we offer free prototype samples (with shipping cost covered by the buyer) for performance testing before mass production.
Our production facilities are ISO 9001:2015 certified, and we follow IATF 16949 quality management processes for high-volume orders to ensure a production yield of 99.8% or higher.
