1、 Source control: Blocking the halogen pollution chain

1. Eliminate secondary pollution in the processing stage
   When processing halogen containing flame retardant materials (such as brominated epoxy resin) in traditional machine barrels, high temperatures can cause halogen compounds to decompose, releasing highly toxic gases such as dioxins. The halogen-free barrel is made of special materials such as high nickel alloy and tungsten carbide, and is equipped with a precision temperature control system (± 1 ℃ accuracy) to stabilize the processing temperature within the safe range of halogen-free materials (such as LCP material processing temperature controlled at 380-420 ℃), avoiding halogen release from the source and ensuring that the production process complies with environmental regulations such as RoHS and REACH.

2. Prevent heavy metals from entering the product
   Through modular design and permanent magnet filtration system (magnetic strength ≥ 12000Gs), the halogen-free drum can capture 99.9% of micrometer sized metal particles. When processing magnesium powder filled PC/ABS halogen-free materials, this technology reduces the surface silver defect rate of the product from 1.2% to 0.03%, avoiding heavy metal pollution of electronic components and meeting the strict requirements of 5G equipment for signal integrity.

2、 Efficiency improvement: reduce energy consumption throughout the entire lifecycle

1. Extend equipment lifespan and reduce resource consumption
   When traditional machine barrels process halogen-free materials, their lifespan is less than 6 months due to corrosion. However, halogen-free machine barrels can extend their lifespan to 3-5 years through a double-layer metal composite structure (inner wear-resistant alloy+outer high-strength carbon steel) and laser cladding repair technology. A company's actual test shows that the full life cycle cost of a single equipment has been reduced by 45%, which is equivalent to reducing steel consumption by 62% and energy input by 83%.

2. Optimize processing parameters and improve energy efficiency ratio
   In response to the high filling and viscosity characteristics of halogen-free materials, the halogen-free barrel adopts a low shear screw groove design (L/D=28:1) and an intelligent temperature control system, which compresses the temperature fluctuation range of the melt from ± 5 ℃ to ± 2 ℃. When processing PA6T halogen-free materials, this technology increases the tensile strength of the product by 15%, while reducing the energy consumption per unit output by 18%, which complies with the ISO 50001 energy management system standard.

3、 Circular economy: supporting closed-loop utilization of materials

1. Compatible with recycled material processing
   The halogen-free barrel can stably process halogen-free materials containing 30% recycled materials through surface hardening treatment (hardness up to HRC65) and corrosion-resistant coating technology. When producing laptop casings, this technology enables the flame retardant rating (UL94 V-0) and surface roughness (Ra=0.8 μ m) of recycled materials to reach the level of raw materials, promoting the conversion of electronic waste into products.

2. Support the development of bio based halogen-free materials
   For bio based halogen-free materials such as PLA/PHBV, the halogen-free barrel solves the problem of poor thermal stability by optimizing the screw compression ratio (2.5:1) and the barrel cooling system. The bio based battery casing developed by a certain enterprise using this technology has reduced its carbon footprint by 67% compared to traditional petroleum based products, and has obtained T Ü V Rheinland carbon neutrality certification.
