Product Description
This high-precision anti-slip knob mold is engineered to solve the
core pain points of "poor grip, inconsistent texture, and size
mismatch" in appliance and instrument knob production. Unlike
traditional machining molds that struggle with uniform anti-slip
texture replication, our solution combines electroforming’s
stress-free deposition with laser texturing’s micron-level
control—ensuring every knob cavity features sharp, consistent
anti-slip patterns that prevent hand slippage, even with oily or
wet hands.
Crafted from automotive-grade nickel-cobalt alloy, the mold boasts
exceptional wear resistance (52-56 HRC) and thermal stability (-40℃
to 150℃), easily withstanding high-temperature resin injection
(180-220℃) and repeated demolding. We offer full customization from
size to texture: whether you need a 10mm mini knob for precision
scales or a 60mm ergonomic knob for oven controls, the mold
delivers ±0.002mm precision to match your product’s exact
requirements. Compliant with FDA 21 CFR 175 (for food-contact
appliances) and ISO 9001, it’s the trusted choice for appliance
brands and instrument manufacturers worldwide.
Core Advantages
1. Precision Anti-Slip Cavity: Enhance Grip & Usability
Laser texturing technology creates anti-slip patterns (ribbed,
knurled, grainy) with ±0.001mm depth tolerance—no blurred edges or
uneven texture. For example, knurled textures on blender knobs
improve grip during high-speed operation, while grainy patterns on
oscilloscope knobs enable precise adjustment without slippage. The
mold’s smooth inner surface ensures texture is perfectly
transferred to the knob, with no "missing texture" defects.
2. Full Customization: Fit Every Knob Requirement
Size Flexibility: Supports knobs from 5mm (mini instrument knobs) to 80mm (large
oven knobs), with tapered or ergonomic shapes tailored to hand
comfort;
Texture Customization: Adjust roughness (Ra 1.5-6μm) and pattern—Ra 1.5-2.5μm for
appliance knobs (comfortable to touch) and Ra 4-6μm for industrial
instruments (enhanced grip);
Structure Adaptation: Integrate internal splines, D-shaped holes, or set screws into
the cavity for seamless assembly with control shafts.
3. Dual-Scenario Durability: Appliances & Instruments
Optimized for different use environments: - Home Appliances: High-purity nickel material meets FDA food-contact standards,
resistant to kitchen oil and detergents (ideal for rice cookers,
air fryers); - Measuring Instruments: Nickel-chromium alloy resists humidity and chemical exposure,
ensuring stable performance in lab or industrial settings (perfect
for oscilloscopes, precision scales). The mold withstands 300,000+
production cycles without texture wear, reducing replacement costs
by 50% vs. standard steel molds.
4. Smooth Production: Fast Demolding & Batch Consistency
Electroformed mold surface (Ra ≤0.008μm) reduces resin adhesion,
enabling fast, damage-free demolding (saving 20% production time).
No mold wear means 99.9% batch consistency—every knob has identical
size and texture, avoiding customer complaints about "loose" or
"stiff" controls. Supports PPAP documentation for automotive or
industrial instrument supply chains.
