Comparison of key mechanical properties between ABS LGF30 and alternative materials
Standard ABS Shortcomings
Insufficient strength, prone to cracking and deformation under long-term stress, and unable to meet the structural requirements of high-load components.
Short Glass Fiber Reinforced ABS Issues
Uneven fiber dispersion and easy fiber breakage during processing lead to unstable finished product performance and a high defect rate.
Metal Substitution Drawbacks
High weight increases energy consumption (especially in automotive parts), increases processing costs, and significantly extends production cycles.
Reinforcement Process: Advanced long fiber infiltration technology
Achieve structural strength close to metal with the cost and weight of plastic. More About ABS LGF30

Production Process Section: LFT-G® ABS LGF30 Pellet Manufacturing
Intro
Our ABS LGF30 (30% Long Glass Fiber Reinforced ABS) pellets are made via a streamlined, high-precision process to ensure consistent fiber dispersion and mechanical strength. Here's our core production flow:
Step-by-Step Production
1. Fiber Roving Prep: Premium fiberglass rovings are unwound and aligned for uniform distribution-critical for maintaining 30% long glass fiber loading in ABS LGF30.
2. Polymer Melting: Virgin ABS resin + performance additives are melted in an extruder to create a homogeneous thermoplastic melt, optimized for fiber bonding.
3. Impregnation (Core Step): Fibers are saturated with molten ABS in an advanced impregnation die, ensuring full coating and a precise 30% fiber-to-resin ratio for ABS LGF30.
4. Pulling & Cooling: The composite strand is pulled to maintain tension, then cooled to solidify the matrix and preserve the 11mm fiber length that defines ABS LGF30 performance.
5. Granulation: The solid strand is cut into 0.5" / 11mm ABS LGF30 pellets, ready for downstream injection molding or extrusion.
Case Study: Automotive Bracket Innovation with LFT-G® ABS LGF30
The Challenge: Heavy, Expensive Aluminum Brackets
A leading automotive supplier faced mounting pressures to reduce vehicle weight while maintaining structural integrity and controlling costs. Their engine mounting brackets, made from aluminum, presented multiple problems:
• Excessive Weight: Each aluminum bracket weighed 850g, adding unnecessary vehicle mass
• High Production Costs: Expensive material + machining + assembly operations
• Complex Manufacturing: Required multiple components, fasteners, and secondary operations
• Corrosion Concerns: Needed additional protective coatings
• Limited Design Flexibility: Difficult to integrate additional features
The client needed a solution that could maintain or improve performance while reducing weight and cost by at least 30%.
The Solution: ABS LGF30 Metal Replacement
Material Switch: Replaced aluminum with ABS LGF30 (30% Long Glass Fiber Reinforced ABS)
Engineering Approach:
Part Consolidation: Redesigned 5 separate aluminum components into a single, injection-molded ABS LGF30 bracket
Topology Optimization: Used FEA analysis to remove non-essential material while reinforcing stress points
Design Integration: Incorporated mounting points, cable routing channels, and structural ribs into one piece
Process Optimization: Implemented hot-runner injection molding with optimized cooling for maximum fiber retention
Key Advantages of ABS LGF30 for this application:
Excellent stiffness-to-weight ratio
Superior vibration-damping properties
Good flow characteristics for complex geometries
Inherent corrosion resistance
Cost-effective raw material vs. aluminum
