Ultra-thick ABS Sheet is scarce with no stable supply; thick sheets warp and deform, have poor dimensional accuracy, and have a high scrap rate after processing, affecting project delivery; severe internal shrinkage cavities and bubbles fail to meet mechanical strength and structural component requirements; long procurement cycles and difficulty in customization mean no one is willing to take on small-batch, high-thickness orders; thick sheets are costly and have a low yield rate, leading to uncontrolled overall processing and material costs; and no professional manufacturer can provide stable mass production of 200mm and thicker sheets. As a professional manufacturer, AHD focuses on ABS Plastic Sheet R&D, breaking through ultra-thick production barriers to solve your procurement pain points

Challenges in producing ultra-thick ABS sheets
1. Extrusion Molding: Challenges in Melt Flow and Uniformity
Ultra-thick ABS sheet extrusion process challenges are prominent. ABS melt viscosity is high, and when thickness exceeds 50mm, the core melt flow rate is only 1/3 of the surface, prone to uneven density. 200mm thick sheets have a huge theoretical deviation risk without process optimization. AHD’s 32-year manufacturing experience optimizes screw design, increasing core melt flow rate to ensure uniform density.
2. Cooling control: Warpage and root causes of internal stress
Thick ABS sheet warping is mainly caused by uneven cooling. The surface cools rapidly and solidifies, while the core cools slowly, generating huge internal stress. Conventional cooling leads to 200mm thick sheets with high warpage and dimensional stability failing industrial standards. Internal shrinkage cavities and bubbles reduce tensile strength by 30%, failing mechanical performance requirements.
3. Mass Production and Customization: The Dilemma of High Costs and Low Yields
Large thickness ABS sheet manufacturing has a yield rate of only 30%-50% for conventional processes, with high raw material and energy costs. Most manufacturers refuse small-batch 200mm ABS sheet orders due to long mold adjustment cycles and high scrap rates.
AHD 200mm Ultra-Thick ABS Sheet Technology Breakthrough Solution
1. Formula Optimization: Low Shrinkage, High-Stability Modified System
| Conventional ABS Sheet | AHD 200mm Ultra-thick ABS Sheet | |
| Shrinkage Rate | 0.5%-0.8% | 0.3%-0.4% |
| Tensile Strength | 38MPa | 45MPa |
| Warpage Degree | 3-5mm/m | ≤0.8mm/m |
2. Technological Innovation: Gradient Cooling and Precision Temperature Control Technology
AHD adopts a three-stage gradient cooling system for ultra-thick ABS sheet technology breakthrough:
Pre-cooling: slow cooling for 30min to release initial stress.
Main cooling: uniform cooling with circulating water, surface-core temperature difference controlled within 5℃.
Post-cooling: constant temperature setting for 2h to eliminate residual stress.
This solves uneven cooling, with 200mm sheets achieving dimensional stability meeting precision equipment requirements.
3. Equipment Upgrade: Advanced Large-Tonnage Extrusion Production Line
AHD has introduced advanced thick-plate extruders, equipped with different dies, to achieve stable production of ABS sheets ranging from 100mm to 260mm. Real-time monitoring of melt pressure, temperature, and flow rate ensures product consistency and significantly improves yield.
