1. Superior Durability & Weather Resistance
PVC gutter profiles, shaped by high-precision extrusion technology, boast exceptional resistance to corrosion, UV radiation, and extreme temperatures. Unlike metal alternatives, they never rust, fade, or deform, ensuring a lifespan of over 20 years with minimal maintenance—ideal for both residential and commercial buildings across diverse climates.
2. Lightweight & Easy Installation
These PVC gutters are lightweight yet structurally robust. They eliminate the need for heavy lifting equipment during installation, cutting down labor costs and construction time significantly. Their modular design also allows for seamless assembly and customization to fit any roof size.
3. Cost-Effective & Eco-Friendly
Extrusion process ensures high material utilization with low waste, making the PVC gutters more budget-friendly than aluminum or steel options without compromising quality. Additionally, the raw materials used are 100% recyclable, aligning with global green building standards and helping your clients reduce their carbon footprint.
4. Excellent Water Flow & Low Noise
The precision-machined smooth inner walls of PVC gutters (guaranteed by extrusion line’s high-accuracy molds) minimize water resistance, ensuring efficient rainwater drainage even during heavy downpours. Compared to metal gutters that produce loud clattering sounds in rain, PVC profiles operate quietly, enhancing the comfort of building interiors.
The quality and output of PVC gutter profiles produced by SHARC Machine’s PVC raining gutter profile production line are directly affected by raw material properties, process parameter control, mold & calibration system performance, and equipment maintenance management. Here are the core influencing factors in detail:
1. Raw Material Characteristics
– PVC Resin Grade & Formula Stability: The molecular weight of PVC resin determines melt viscosity—too high a molecular weight leads to poor fluidity and uneven plasticization, while too low causes weak profile strength. Stabilizers, lubricants, and fillers must be accurately proportioned; inconsistent ratios will result in surface defects (e.g., streaks, bubbles) and reduced impact resistance of gutters.
– Moisture Content: Excess moisture in raw materials (>0.1%) will produce bubbles, silver streaks, or pinholes on the profile surface. Raw materials must be fully dried before extrusion, especially in high-humidity environments.
– Material Purity: Impurities or foreign particles in raw materials will cause surface scratches, black spots, or even mold blockages, affecting continuous production.
2. Extrusion Process Parameter Control
– Temperature Profile: The temperature of the extruder barrel, screw, and die must be gradient-controlled. Overheating causes PVC decomposition (yellowing, charring), while insufficient temperature leads to incomplete plasticization, resulting in rough surfaces and internal stress cracks in gutters.
– Screw Speed & Traction Speed Coordination: Screw speed determines melt output, and traction speed controls profile shaping. Mismatched speeds will cause problems: faster traction leads to thin walls, size deviation, and deformation; slower traction results in thick walls, high internal stress, and easy cracking during installation.
– Vacuum Calibration & Cooling Conditions: The vacuum degree of the calibration tank affects the profile’s dimensional accuracy—excessive vacuum causes surface scratches, while insufficient vacuum leads to unclear profile contours. Uneven cooling water temperature (optimal range: 20–30℃) or uneven water flow will cause gutter bending, twisting
