PC Lampshade Cover Making Machine, PC Diffuser Tube Light Extrusion Machine

【YAOAN Intelligent Manufacturing】High Efficiency & Precision · PC Lampshade Extrusion Line —— Illuminating Industrial Excellence

In today's rapidly evolving lighting industry, PC lampshades have become indispensable core components in fields such as LED lighting, automotive lamps, advertising light boxes, and smart homes, thanks to their excellent light transmittance (up to 88%-90%), superior impact resistance (200 times that of ordinary glass), and lightweight characteristics. However, PC material is extremely sensitive to processing conditions—trace moisture can cause bubbles in products, and temperature fluctuations can lead to dimensional deviations.
How can you achieve high efficiency, high yield, and high consistency in large-scale PC lampshade production? Dongguan YAOAN Intelligent Equipment Co., Ltd. provides you with a comprehensive deep solution from raw material handling to finished product cutting.

YAOAN PC Lampshade Extrusion Line · In-Depth Core Technology Analysis

We understand that high-quality PC lampshades stem from the ultimate pursuit of process perfection. The YAOAN PC Lampshade Extrusion Line integrates automation, precision, and stability, making it a powerful partner to enhance your production capacity and quality. The complete line consists of six core units, each rigorously validated through engineering:

1. Raw Material Pre-treatment Unit: Precision Drying, Eliminating Defects at the Source

High-Efficiency Auto Loader: Utilizes closed negative pressure conveying technology to eliminate dust spillage, ensuring a clean working environment; equipped with a material level sensor for unattended continuous material supply.

Large-Capacity Dehumidifying Drying Hopper: Specifically designed for the hygroscopic nature of PC material, equipped with a honeycomb rotor dehumidifier achieving a dew point of -40℃. Integrated design combining dehumidification, drying, and conveying ensures the PC moisture content is strictly controlled below 0.02%, fundamentally preventing bubbles, silver streaks, or yellowing in the final products.

2. Extrusion Plasticizing Unit: Core Power, Guaranteeing Melt Uniformity

S specialized PC Single Screw Extruder:
S screw Design: Features a barrier type + mixing head structure specialized for PC, with an L/D ratio up to 33:1, sisignificantly enhancing plasticizing efficiency and mixing effect, ensuring uniform molecular weight distribution of the material and improving melt fluidity.

T temperature Control System: Equipped with imported brand PID intelligent temperature control modules

a cross five independent temperature control zones, achieving precision up to ±1℃, effectively preventing

d degradation of PC material due to localized overheating.

D drive System: Driven by an AC variable frequency or servo motor, providing high output torque and low energy

c consumption, ensuring stable operation even under high backpressure conditions.

3. Precision Forming Unit: Die Design, Shaping the Initial Form

PC Specialized Extrusion Die:
Material & Flow Channel: Made of high-quality H13 or 5CrNiMo die steel, subjected to vacuum heat treatment and nitriding, offering high hardness, wear resistance, and long service life. The flow channel is designed using fluid simulation optimization, featuring a streamlined shape with no dead spots, ensuring uniform melt pressure distribution to the die lip.
Lip Adjustment: Equipped with high-precision restrictor bar adjustment bolts and die lip micro-adjustment devices, allowing precise control of the extrudate thickness uniformity, effectively eliminating weld lines, and ensuring lampshade wall thickness tolerances are controlled within a minimal range.

4. Vacuum Sizing & Cooling Unit: Shape Solidification, Guaranteeing Precise Dimensions

Vacuum Calibration Cooling Tank:
Multi-Stage Sizing Technology: Typically equipped with 2-4 sets of precision sizing sleeves, utilizing a stepped aperture design to gradually cool and solidify the high-temperature parison to the final dimensions. The sizing sleeves utilize water circulation cooling for high efficiency.
Powerful Vacuum System: Configured with a high-power water ring vacuum pump, combined with precision-machined vacuum slots on the sizing sleeves, generating strong and uniform adsorption force, ensuring the round tube or profile tightly adheres to the inner wall of the sizing sleeve, guaranteeing outer diameter precision and roundness.
Circulating Cooling System: The main tank body is made of stainless steel, equipped with multi-dimensional adjustment devices (up/down, left/right) for easy alignment with the haul-off center; multi-stage spray and immersion ensure thorough cooling of the product, eliminating internal stress.

5. Stable Haul-Off Unit: Synchronized Output, Eliminating Tensile Stress

Servo-Driven Belt Haul-Off:
Drive Method: Employs servo motor drive coupled with a high-precision gearbox, offering fast response and excellent synchronization. The haul-off speed forms a closed-loop control with the extrusion speed, preventing slippage and uneven stretching.
Clamping Structure: Utilizes pneumatic or hydraulic clamping with adjustable and stable pressure. The belt contact surface features high-friction rubber pads, providing sufficient traction without damaging the lampshade surface.

Applicability: Adapts to multiple diameter specifications, easy to adjust when changing products, effectively ensuring the continuity and stability of the extrusion process.

6. Automatic Cut-to-Length Unit: Precision Cutting, Efficient Collection

Automatic Cut-to-Length Saw:
Cutting Method: Options include sawing cutting depending on pipe diameter. Cuts are smooth and flat, free from dust pollution, eliminating the need for secondary trimming.
Control System: Equipped with a high-precision encoder length measurement system. Cutting length can be arbitrarily set on the touch screen, achieving precision up to ±0.05mm. The cutting action synchronizes in real-time with the haul-off speed, achieving "flying saw" effect without interrupting continuous line operation.
Automatic Dump Rack: Finished products automatically fall onto the dump rack after cutting, stacking neatly for easy packaging, significantly reducing labor intensity.
