Custom Injection Molded Transparent Enclosure Parts

Core Processing Technologies: The Foundation of High-Quality Transparent Enclosures

1. High-Precision Injection Molding Equipment & Parameter Control

• Advanced injection molding machines: Equipped with 20+ sets of precision injection molding equipment (100-500 tons clamping force), including Haitian MAⅢ series and Sumitomo SE-EV models. These machines feature servo-electric drive systems for stable pressure control (±0.1bar) and high-speed injection (up to 300mm/s), ensuring uniform melt filling even for thin-walled enclosures (minimum wall thickness 0.3mm).
• Intelligent parameter optimization: Adopts MES system to real-time monitor and adjust key parameters (melt temperature, injection speed, holding pressure) based on material properties. For example:
  • PC materials: Melt temperature controlled at 280-300℃, holding pressure 80-100bar to prevent internal stress and cracking.
  • PMMA materials: Lower injection speed (50-80mm/s) to avoid shear-induced yellowing, ensuring 92%+ light transmittance.

2. Ultra-Precision Mold Manufacturing & Surface Treatment

• Mirror polishing technology for molds: Molds for transparent enclosures undergo 8-level mirror polishing (Ra≤0.02μm) using diamond abrasives and ultrasonic polishing machines. This eliminates mold surface defects (scratches, pits) that could transfer to the product, ensuring the final enclosure has a “glass-like” smooth surface.
• High-efficiency cooling system design: Integrates 3D-printed conformal cooling channels (±0.1mm precision) that fit the enclosure’s complex contours. Cooling time is reduced by 30% compared to traditional straight channels, minimizing warpage (≤0.1mm/m) and improving dimensional stability.
• Anti-sticking mold technology: For PMMA and PETG materials prone to adhesion, the mold cavity is treated with PVD coating (titanium nitride), reducing friction coefficient by 40% and ensuring smooth demolding without scratches.

3. Advanced Secondary Processing & Assembly Technologies

• Precision cutting & drilling: Uses 5-axis CNC machining centers (DMG MORI model) with ±0.002mm positioning accuracy to process holes, slots, and notches on transparent enclosures. Suitable for electronics enclosures requiring precise alignment with internal components (e.g., sensor ports, button positions).
• Laser welding: Adopts fiber laser welding technology (welding seam width 0.1-0.5mm) for assembling multi-piece transparent enclosures. Compared to traditional glue bonding, it avoids residue and yellowing, ensuring 100% airtightness and maintaining 90%+ light transmittance at the joint.
• Optical coating: In-house vacuum coating line applies anti-reflective (AR) or anti-fingerprint coatings. AR coating reduces light reflection from 8% to ≤1.5%, enhancing display clarity for screen enclosures; anti-fingerprint coating makes the surface oil-repellent, reducing cleaning frequency by 50%.

4. Strict Quality Inspection Technology

• 3D optical measurement: Uses Zeiss COMET L3D 3D scanners to inspect the entire enclosure surface, with a point cloud density of 5 million points/sec. Dimensional deviations are visualized in color maps, ensuring all key dimensions (length, thickness, hole position) meet ±0.005mm tolerance requirements.
• Optical performance testing: Equipped with UV-Vis spectrophotometers (PerkinElmer Lambda 950) to detect transmittance (380-780nm wavelength) and haze; only products with transmittance ≥90% and haze ≤1% pass inspection.
• Defect detection: Automated optical inspection (AOI) systems with 20MP cameras and AI image recognition (99.9% defect recognition rate) identify micro-bubbles (≥0.05mm), scratches (length ≥0.1mm), and foreign particles, ensuring zero defective products in mass production.

Technical Advantages in Material Adaptation

 

Application Cases: Technology in Action

• Medical monitor enclosures: For a Fortune 500 medical device company, we produced PC transparent enclosures with 0.8mm thin walls. Using conformal cooling and laser welding, the product passed ISO 13485 certification, with transmittance ≥91% and dimensional stability after 1000 sterilization cycles (autoclave 134℃).
• Smart home display enclosures: Custom PMMA enclosures with AR coating for a leading IoT brand. The 5-axis CNC machined ports ensured precise alignment with internal circuit boards, and the anti-fingerprint coating reduced customer complaints by 60%.
