High-Precision Electrical CD Pattern Round Knobs: Custom Injection
Molding Solutions
To meet the demand for precision operational components in
household appliances, smart electronics, and other industries, we
offer custom injection molding solutions for high-precision
electrical CD pattern round knobs. By integrating CD pattern
technology with round knob structures, our tailored solutions
address both functional and aesthetic requirements across diverse
electrical scenarios.
- Custom Size Range: Diameter 5-50mm, thickness 1-8mm, supporting specialized round
knob structures (e.g., stepped, flanged). Coaxiality error ≤0.01mm
ensures precise assembly.
- CD Pattern Customization: Adjust spacing (0.08-0.5mm), depth (0.02-0.1mm), and density
based on electrical design specifications. Supports continuous
concentric circles or segmented patterns, balancing anti-slip
texture and reflective decoration.
- Mold Precision Guarantee: Cavity surface roughness Ra ≤0.03μm, ensuring 99% clarity of CD
patterns on molded round knobs with no burrs or edge
collapse—meeting IP65 dustproof and waterproof standards for
electrical products.
Kitchen Appliances: For high-temperature and oil-contaminated environments, we use
S136 corrosion-resistant mirror steel molds. A CD pattern spacing
of 0.2-0.3mm ensures anti-slip operation while facilitating daily
cleaning. Molded knobs pass 100,000 rotation tests (5N load) with
98% CD pattern retention, compatible with high-temperature plastics
like ABS/PC.
Smart Home Appliances: Combining etching-filling technology, mold surfaces feature CD
pattern grooves (0.15-0.25mm spacing) filled with high-transparency
epoxy resin, enabling knobs to achieve "matte metallic finish when
powered off + glowing CD patterns when powered on." Molds are
compatible with two-shot injection parameters (e.g., PMMA melting
temperature 230-250°C, TPU holding pressure 50-70bar) for tight
bonding between light-transmitting layers and substrates.
Commercial Electrical Equipment: To withstand frequent operation and harsh environments, cemented
carbide (WC-Co) molds are used. A CD pattern depth of 0.05-0.1mm
enhances wear resistance, allowing knobs to endure 500,000+ presses
with no significant pattern wear. Mold surfaces undergo special
treatment to resist repeated wiping with 75% alcohol, meeting
disinfection requirements for medical devices.
- End-to-End Custom Response: Deliverable from 3D drawing analysis to mold trial within 7
business days, supporting small-batch trials (0-20 units) and mass
production scaling (800 units/batch).
- Flexible Process Matching: Customize optimal process combinations based on production
volume, budget, and performance needs (electroforming for mass
production, CNC + laser engraving for small batches), reducing
trial-and-error costs by 30%.
- Lifecycle Support: Provide mold maintenance manuals (including pattern repair
solutions) and injection parameter guidance (e.g., melt
temperature, holding pressure) to ensure ≥99.5% consistency of CD
patterns during mass production.
Company Profile
As the manufacturing backbone of Heya Precision (Dongguan HeYa Precision Mould Co., Ltd.), our factory is
purpose-built to deliver precision, consistency, and
reliability—supporting your electroformed mold core, plastic
molding, and OEM/ODM needs since 2005.
- Strategic Location: Based in Dongguan, China’s core precision manufacturing
hub—enabling efficient access to raw material suppliers, logistics
networks, and global shipping ports (Shenzhen/Hong Kong), ensuring
timely delivery for international clients.
- Optimized Space: Over 1000㎡ of dedicated production area, divided into functional
zones (precision machining, electroforming, plastic molding,
surface treatment, and quality inspection) to streamline workflows
and minimize cross-contamination risks.
- Compliant Environment: Adheres to industrial safety and environmental standards, with
well-ventilated workspaces, anti-static flooring in precision
zones, and organized storage for mold components—reflecting our
commitment to orderly, professional production.
Our factory is equipped with advanced machinery to uphold Heya Precision’s promise of micron-level accuracy:
- Precision Machining Zone: Hosts high-speed CNC engraving machines (for intricate mold
details) and multi-axis CNC machining centers—capable of handling
complex mold geometries with dimensional tolerance as tight as
±0.005mm, critical for electroformed mold cores.
- Surface Treatment Zone: Features in-house mold texturing (pattern etching) and brushing
finish equipment—eliminating reliance on third-party vendors to
reduce lead times. We also offer outsourced texturing/brushing
services for external mold manufacturers, showcasing our flexible
capabilities.
- Plastic Molding Zone: Includes injection molding machines tailored for small-to-medium
volume plastic parts, compatible with diverse resins (PC, PMMA,
ABS) commonly used in automotive, electronics, and consumer goods
industries.
- Skilled Workforce: A 30+ team of experienced professionals, including 5+ senior mold
engineers (with 10+ years in precision machining), 12+ certified
technicians, and dedicated quality inspectors—ensuring every stage
(from raw material intake to final mold testing) meets Heya Precision’s standards.
- End-to-End Quality Checks: Embeds strict inspection checkpoints:
- Raw material verification (mold steel, resins) with supplier
certificates;
- In-process testing (CMM measurements for machining accuracy,
surface roughness tests for texturing);
- Final validation (mold trial runs, dimensional sampling) before
shipment.
Our factory’s layout and processes are designed to adapt to your
unique needs:
- Flexible Production Lines: Accommodate small-batch prototype orders (e.g., 1–10 mold cores)
and medium-volume production (100–5,000 plastic parts) without
compromising precision.
- Collaborative Workflow: Dedicates project managers to OEM/ODM clients, ensuring clear
communication between your team and our factory—from design
confirmation (DFM analysis) to production scheduling and
post-delivery support.


At Heya Precision, our factory isn’t just a production site—it’s a partner in your
success. Every machine, process, and team member is aligned to turn
your precision mold and plastic component needs into reality, on
time and to spec.
