light fixture injection moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized light fixture injection moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For light fixture injection moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

The injection molding of lamps must follow the three core principles of optical-grade precision, heat-resistant stability, and efficient intelligent manufacturing. The following are systematic technical analysis and operation points:

I. Material Science Breakthrough (2025 Optical-Grade Polymer)

1. Material Selection Matrix

Light-diffusing PMMA, LED lampshade, transmittance 92% + haze 85%

Weather-resistant ASA, outdoor lamp housing, UV resistance 5000 hours without yellowing

Flame-retardant PC/ABS, downlight structural parts, UL94 V-0 grade (0.4mm thickness)

Glass fiber reinforced PP, large street lamp base, bending modulus ↑280% (vs pure PP)

II. Intelligent mold system (optical-mechanical-electrical integration)

1. Core design standards

graph TB

A[Optical simulation] --> B(Light diffusion microstructure design)

B --> C[Conformal cooling water channel]

C --> D[Nano coating]

D --> E[IoT strain sensor]

Optical structure innovation:

Microprism array (beam angle control ±3°)

Submicron bite (Ra=0.2-0.5μm anti-glare)

Life guarantee:

Core material: powder metallurgy H13 steel (hardness HRC60±1)

Surface treatment: diamond-like coating (friction coefficient ≤0.03)

III. Precision injection molding process (zero defect control)

1. Key process parameter matrix

Melt temperature, 220-280℃±1℃, infrared spectrum online analysis, transmittance ↓3% for every 5℃ deviation

Injection speed, 80-120mm/s±2%, servo motor encoder feedback, flow mark/focus risk ↑300%

Packaging pressure, 60-100MPa±0.3MPa, cavity pressure sensor array, shrinkage fluctuation＞0.15%

Mold temperature, 60-90℃±0.5℃, distributed thermocouple network, residual stress ↑ leads to cracking

2. Defect prevention technology

Bubble elimination:

Vacuum-assisted injection molding (cavity pressure ≤ 5mbar)

Ultrasonic melt degassing device (gas content < 0.1%)

Weld line weakening:

Local mold temperature control (temperature difference ± 30℃)

Micro-exhaust structure in welding area (depth 0.01-0.03mm)

IV. Quality monitoring system (optical level detection)

1. Full-dimensional detection technology

Light transmittance uniformity, imaging colorimeter, Δxy≤0.003,

Structural dimensions, blue light 3D scanner, ±0.02mm

Surface defects, AI machine vision, identification of ≥ 0.1mm² defects

Heat aging resistance, thermal cycle test chamber, 85℃/1000 hours

V. Green smart manufacturing practice (2025 strong standard)

1. Energy saving and carbon reduction technology

A[recycled material pretreatment] --> B(supercritical cleaning and impurity removal)

B --> C[electromagnetic induction heating]

C --> D[waste heat recovery power generation]

D --> E[Carbon Neutrality Certification]

Carbon footprint control:

Carbon emissions per ton of product ≤620kg CO₂ (traditional process ≈1100kg)

Photovoltaic power supply coverage ≥40%

2. Circular economy solution

Chemical recovery of PC: closed-loop depolymerization → monomer purity 99.97% → regeneration of optical grade materials

Mold steel regeneration: laser cladding repair (cost ↓65% lower than new mold)

VI. Risk control list

Optical performance attenuation, 3000h light flux maintenance rate ≥90%, adding hindered amine light stabilizer

VOC release, formaldehyde ≤0.01mg/m³, molecular sieve adsorption devolatilization process

Electrical safety, IP67 waterproof structure design, ultrasonic welding + sealing ring composite
