From April 21 to 24, 2026, the 38th China International Exhibition on Plastics and Rubber Industries (CHINAPLAS) will kick off. Gillkon Screw will make a high-profile appearance with three flagship products: cermet screws, special screws for fluoroplastics, and energy-saving drying-free screw & barrel assemblies, providing targeted solutions to three major industry pain points: wear resistance, corrosion resistance and energy saving!
We sincerely invite industry colleagues from automotive, electronics, medical, high-end packaging and other fields to visit our booth 4.1C17 to explore efficient injection molding solutions and discuss high-quality development of the industry together!
Core Exhibited Products | Part 2
In injection molding production, common issues such as high wear, strong corrosion and high energy consumption often lead to rapid wear of ordinary screws, or failure to balance efficiency and quality, seriously slowing down production and increasing costs. Gillkon’s three flagship products are designed to solve these core industry problems!
1. Cermet Screw | Ultra-Wear Resistant & Ultra-Corrosion Resistant
Material & Technology:
Made of high-purity alloy powder formed by vacuum high-temperature sintering, with uniform, dense and non-segregated alloy composition, excellent high-temperature toughness and resistance to high-temperature softening. Nano-scale spherical metal powder achieves the optimal ratio of wear-resistant and corrosion-resistant metal elements. Special ceramic components are added and sintered under vacuum to form composite expanded particles.
Core Performance:
Hardness 58–62 HRC, ultra-wear resistant and ultra-acid corrosion resistant, suitable for working conditions below 650℃.
Application Scenarios:
Halogen-free plastics with 50% GF and other high-fiber, high-wear, halogen-free and high-acid corrosion environments. Compatible with raw materials including DSM PA4T, Kingfa PA6T, PA10T, DuPont HTN, etc.
Two-year warranty.
2. Special Screw for Fluoroplastics (Patented Product)
Specially developed for fluoroplastic production, with customized grades from civil to semiconductor level, perfectly solving production pain points such as heat resistance, cold resistance and acid corrosion resistance. Preferred by 90% of domestic semiconductor fluoroplastic product manufacturers.
Polyfluoro No.3 | High-End Semiconductor Grade (Core Promotion)
Material & Performance:
Adopts imported nickel-based tungsten carbide spherical alloy powder, suitable for long-term use under 550℃. Tensile strength 1150MPa, yield strength 820MPa, iron content below 1%, metal ion content controlled at PPT level.
Core Advantages:
Eliminates screw deformation and barrel scraping during high-pressure injection; prevents reductive corrosion of iron by hydrofluoric acid gas, improving product purity and yield; reduces startup/shutdown difficulty and screw deformation; resolves blackening and black spot issues in flow channels, and enhances anti-corrosion protection.
Supporting Services:
Provides full-chain turnkey services for production capacity implementation, including clean room construction, machine selection, mold technology, etc.
Application Fields:
Civil fields such as wires & cables, solar photovoltaic, chemical engineering; semiconductor & photovoltaic fields such as wafer carriers (cassettes), photovoltaic pipe fittings/tees.
Compatible Materials:
PFA/PVDF/PTFE/FEP. Solutions for excessive metal ions in high-purity PFA for the semiconductor industry are available.
3. Energy-Saving Drying-Free Screw & Barrel Assembly | Patented Technology (ZL202122366462.3)
Subverts traditional raw material drying processes, enabling direct production without pre-drying through proprietary screw technology, mainly solving pain points such as high drying cost, complicated operation and high workshop temperature.
Exhaust Principle:
Abandons external drying equipment. Moisture is instantly vaporized by raw material self-temperature plus screw shearing, and efficiently discharged through a dedicated exhaust port in the middle of the barrel, achieving dry material production.
Core Advantages:
-
Extreme Energy Saving: Reduces processing electricity cost by over 30%, eliminating equipment, time and labor costs for drying.
-
Easy Operation: No pre-drying preparation required; startup with small amount of raw materials to avoid waste.
-
Quality Improvement: Better toughness of finished products, excellent molding performance for PA + glass fiber materials.
-
Eco-Friendly: Reduces drying heat sources and improves workshop working environment.
Application Scenarios:
All injection molding production requiring raw material drying, especially for large-scale, high-energy-consumption enterprises.
