Resin Tile Conical Twin Screw

Nanhaiya Resin Tile Conical Twin Screw is China's earliest manufacturer specializing in the production of conical twin-screw barrels specifically for resin tiles. With over a decade of experience in plastics machinery, we utilize advanced production processes and equipment to design and manufacture a wide range of screw types. Our products offer competitive pricing and cover a wide range of European and American markets. We look forward to becoming your long-term partner in China.

Product Introduction

This resin tile conical twin-screw is made from 38CrMoAla steel. Raw material is crucial to screw performance, and we select high-strength and wear-resistant steel from renowned Chinese steel producers that meets national standards (GB/T 3077).

We utilize a thread rolling process. This process creates a fuller, stronger thread profile, preventing breakage. It also controls the thread pitch error to ≤0.1mm, ensuring uniform engagement and minimizing loosening.

Nanhaiya's resin-clad conical twin-screw barrels have undergone numerous R&D and improvements and are now integrated into various manufacturers' production lines, achieving state-of-the-art performance. We offer a 1-2 year warranty, depending on the specific material addition ratio. Nanhaiya's barrels undergo a nitriding process, with a 2mm thick layer of nickel-tungsten alloy spray-welded on the most wear-prone areas. This increases the surface hardness of the barrel from HRC55-60 to over HRC65, boosting wear resistance by 2-4 times.

Feature And Application

Nanhaiya's tapered screw with a gradual pitch design for resin tiles can gradually increase the shear and compression of the PVC mixture, achieving high-efficiency plasticization at low temperatures, avoiding decomposition of additives, and ensuring the anti-aging performance of the resin tiles.

The meshing structure of the screw can stably control the melt pressure, reduce fluctuations, ensure that the thickness of the hollow cavity or surface of the resin tile is uniform during extrusion molding, and improve structural stability.

The multi-stage exhaust port design of the barrel can effectively discharge moisture and volatiles from the raw materials. Combined with the strong mixing ability of the twin screw, the additives are evenly dispersed, ensuring that the surface of the resin tile is smooth and free of defects.

 Resin tiles are a new type of building material that is lightweight, waterproof, heat-insulating, and corrosion-resistant. They are widely used in the construction field and can be used for roofing, wall materials, decorative materials, awnings, and sunshades.

Details

Advanced tempering, precision machining, and nitriding processes ensure the comprehensive performance of core components.

Vulnerable areas of the screw and barrel are reinforced with a nickel-tungsten alloy layer, achieving a 2-3mm thick layer and significantly improving wear resistance.
