Customer Reviews

We attach great importance to precision. Hoya's molds have an error of only ±0.005mm, and can be used right from the first try. Although Heya is new to exporting, it has a very good understanding of automotive molds and is truly trustworthy!

—— Nguyễn Văn Hiếu

Heya's molds are accurate to 0.004mm and have excellent corrosion protection. Delivery is fast, within 3 weeks, definitely better than domestic suppliers!

—— Somchai Phetchakul

We needed a precise hook structure. Hoya immediately provided excellent advice based on the 3D design, resulting in a 100% perfect fit without any adjustments. Despite being a new exporter, Heya truly understood our needs!

—— Rina Sari

The mounting holes need to be very precise. Heya's mold accuracy is ±0.005mm, allowing for immediate installation. Responsive to design revisions, very professional for a new supplier!

—— Lim Chee Seng

Providing customized corrosion resistant solutions for us. Mold life in humid & hot environments increased by 2 times. Local service team responds quickly.

High Precision Electroformed Inserts For Appliance Knobs

Engineered as core structural components for appliance knobs, these high-precision electroformed inserts solve critical industry challenges: loose fitting (knob wobble) and short service life (wear-induced failure). Unlike traditional machined inserts prone to dimensional deviation, electroforming deposits nickel alloy layer by layer—creating a dense, stress-free structure with ±0.001mm precision.

Product Specifications

Attribute	Value
Product Name	High Precision Electroformed Inserts - Durable Tight-Fit For Appliance Knobs
Highlight	Micron-level tight fit, wear-resistant electroformed structure, enhanced knob durability, 360° smooth control
Tolerance	±0.001mm (insert outer diameter); ±0.002mm (internal spline/groove); ≤0.002mm fitting clearance
Hardness	52-56 HRC (nickel-cobalt alloy, 20-25% Co); 48-52 HRC (high-purity nickel, 99.95%)
Feature	Ra ≤0.008μm smooth surface (low friction), corrosion-resistant (oil/cleaners), no internal stress, 500,000+ rotational cycles
Processing Method	High-precision electroforming (nickel ion deposition) + CNC micro-trimming (fitting surface refinement) + Anti-corrosion coating
Material	Nickel-cobalt alloy (high wear resistance for frequent use), high-purity nickel (stable dimensional accuracy), nickel-chromium alloy (corrosion resistance)
Application	Kitchen appliance knobs (rice cooker temperature controls, oven timer dials), laundry appliance knobs (washing machine program settings), small home appliance knobs (air fryer temperature adjusters, blender speed dials)

Core Advantages

±0.001mm Tight Fit - No Wobble, No Loosening

Micron-Level Dimensional Accuracy: Electroforming's layer-by-layer deposition ensures ±0.001mm tolerance—creating a "zero-play" fit with knob body and control shaft
Consistent Fitting Clearance: ≤0.002mm clearance prevents loosening over time, even after repeated assembly/disassembly or thermal expansion
Universal Shaft Compatibility: Supports internal spline, square hole, or D-shaped hole designs—customizable to match appliance control shafts

Enhanced Durability - 500,000+ Rotational Cycles

Wear-Resistant Nickel-Cobalt Alloy: 52-56 HRC hardness resists abrasion from rotational friction—no metal shavings or deformation
Stress-Free Structure: No internal stress maintains dimensional accuracy across -40℃ to 120℃ temperature range
Corrosion Resistance: Nickel-chromium alloy variant resists oils, cleaning agents, and moisture—no rust-induced binding

Smooth Control Experience - 360° Friction-Free Operation

Ultra-Smooth Surface: Ra ≤0.008μm finish reduces friction coefficient to 0.05—enabling effortless, silent rotation
Precise Torque Control: Consistent dimensional accuracy ensures uniform torque across all knobs—avoiding "stiff" or "loose" variations

Application Scenarios

Appliance Category	Target Knobs	Core Benefit
Kitchen Appliances	Rice cooker temperature dials, oven timer/heat controls, air fryer temp adjusters	Tight fit for precise temperature control; corrosion resistance to kitchen grease
Laundry Appliances	Washing machine program knobs, dryer cycle selectors	Wear resistance for frequent use; no wobble during adjustment
Small Home Appliances	Blender speed dials, coffee maker setting knobs, toaster browning controls	Smooth operation; durable for daily adjustments

Customization Support

Structural Customization: Tailor internal design (spline count, hole shape/size) to match your control shaft—accepts 3D CAD files (STEP, IGES) or physical samples
Size Adaptation: Supports insert diameters from 3mm to 20mm, lengths from 5mm to 30mm—ideal for mini knobs and large dials
Material Tuning: Recommend alloy based on use case: nickel-cobalt for high-frequency use, nickel-chromium for humid environments

Quality & Service Commitment

Quality Inspection

CMM (±0.0005mm accuracy) for dimensional tolerance verification
Laser confocal microscopy confirms surface roughness Ra ≤0.008μm
Rotational durability testing simulates 500,000 cycles to confirm wear resistance

Compliance & Standards

Meets ISO 9001 (quality management) and FDA 21 CFR Part 175 (food contact safety) standards—full traceability documentation provided

Technical Support

Dedicated engineers advise on insert-knob matching and mold integration—available for pre-production sample testing
