High-Quality Electronic Plastic Housing Service & Factory

Micro-Miniaturization & Ultra-Thin Walls

Modern handheld IoT, consumer wearables, and smart automotive sensors require wall thicknesses scaled down to 0.40mm - 0.60mm without structural buckling or weld-line embrittlement. Achieving this requires high-speed electric injection units, high-flow liquid crystal polymers (LCP), and polyphthalamide (PPA) blends coupled with vacuum-assisted cavity evacuation.

• Sub-0.5mm nominal wall thickness capability
• Differential shrinkage mitigation via Moldflow

Thermally Conductive Engineering Resins

High-power density electronics (such as GaN fast chargers, LED controllers, and ADAS edge computers) are dumping metal die-castings for weight reduction. Through ceramic- and graphite-filled polymers (TC-plastics reaching 1.0 to 15.0 W/m·K), our injection molding processes yield enclosures that actively dissipate heat while offering dielectric electrical isolation up to 25 kV/mm.

• Conductivity range: 1.5 - 12.0 W/m·K (in-plane)
• Zero-corrosion, 40% weight reduction vs ADC12

Integrated EMI/RFI Shielding Solutions

Eliminating the messy secondary operation of conductive spray painting or nickel plating, modern housing engineering leverages carbon-nanotube (CNT) doped compounds, stainless steel fiber masterbatches, and selective in-mold physical vapor deposition (PVD). This delivers 40dB - 70dB attenuation across 30 MHz to 18 GHz frequencies directly out of the press tool.

• Compliance: FCC Part 15 & CISPR 32 Class B
• Eliminates secondary chemical overspray costs

Post-Consumer Recycled & Bio-Polymers

Global carbon border taxes and ESG directives mandate sustainable engineering materials. We formulate UL-Yellow-Card certified post-consumer recycled (PCR) polycarbonates (up to 85% rPC) and bio-based Polyamides (PA1010/PA11) that preserve halogen-free UL94-V0 flame retardancy, RTI values over 105°C, and pristine cosmetic piano-black or frosted finishes.

• UL 94-V0 flammability down to 0.75mm
• Complete material traceability & RoHS/REACH

Ultra-High Precision Toolroom Tech

Tool durability is the bedrock of electronic housing consistency. Our tooling facilities operate 5-axis Makino D200Z and Roku-Roku high-speed graphite milling centers (up to 40,000 RPM) paired with Swiss AgieCharmilles Form 200/300 mirror-finish EDMs. This guarantees intricate rib roots, undercut slider locks, and core-cavity alignment accuracy within 3 microns.

• Steel Grades: ASSAB S136, Stavax ESR, NAK80, 1.2343
• Mirror Polish: SPI A-1 diamond finish (Ra < 0.012 µm)

All-Electric Injection & Robotics

Our cleanroom injection cell houses clamping forces from 30 tons to 650 tons powered by all-electric Sumitomo and Fanuc Roboshot machines. Digital closed-loop servo feedback provides injection speed control to 0.01 mm/s. Integrated 6-axis linear robots ensure zero-contact part demolding, insert placement, and continuous automated visual sorting.

• Class 100,000 (ISO Class 8) cleanroom production
• Automated brass threaded insert heat-staking

Metrology Laboratory & Automated AOI

Quality control is executed in an environmentally controlled constant-temperature metrology suite. Every batch is evaluated against critical GD&T features using bridge-type Zeiss CMMs, Keyence automated optical image measuring systems, and laser 3D scanning for comprehensive surface contour error color mapping.

• Volumetric measurement accuracy: 0.9 µm + L/350
• Real-time statistical process SPC chart generation

DFM Stage 1: Wall & Rib Optimization

We audit internal boss towers and stiffening ribs to adhere strictly to a 0.50x to 0.60x nominal wall ratio, preventing sink marks on Class-A cosmetic surfaces. Draft angles are evaluated at a minimum of 1.0° to 1.5° for smooth ejection, with heavy textured finishes (VDI 3400 / SPI) optimized up to 3.0° - 5.0° to prevent drag scarring.

DFM Stage 2: Rheological Fill & Warpage FEA

Utilizing Autodesk Moldflow Insight, we simulate fiber orientation vectors in reinforced plastics (e.g. PA66-GF30) to predict anisotropic shrinkage and warpage before steel machining. Gate designs (valve-gated hot runners, sub-gates, edge fans) are precisely engineered to locate weld lines outside of high-stress zones.

DFM Stage 3: Verification & Environmental Stress

Validation covers First Article Inspection (FAI) with 100% full-dimension bubble drawings. Parts undergo thermal shock testing (-40°C to +85°C across 500 cycles), glow wire flammability (GWFI/GWIT), salt spray fog corrosion testing on overmolded pins, and drop impact testing from 1.5 meters onto solid concrete.
