Product Name: Precision Engineered Machine Screw Product Description: Our machine screws are meticulously crafted to deliver exceptional durability, precision, and reliability across a range of industrial and commercial applications. Designed to meet OEM standards, these screws are suitable for assembly in machines, electronics, automotive, and construction industries. Key Features: Material: High-grade stainless steel, carbon steel, or alloy steel for superior strength and corrosion resistance. Size Range: Customizable lengths and diameters are available as per specifications. Threading: Accurate and smooth threading ensures easy installation and a secure fit. Finish Options: Zinc plating, black oxide, nickel, or custom coatings for enhanced aesthetics and protection against wear and corrosion. Tolerance: Manufactured strictly to ISO/ANSI/DIN standards to guarantee dimensional accuracy. Applications: Widely used in machinery assembly, electronic enclosures, automotive assemblies, and structural applications. Production Process for Machine Screws: Material Selection: High-quality raw materials like stainless steel rods or carbon steel wires are selected based on the required properties. Cutting: The raw material is cut into precise lengths matching the screw size using automatic cutting machines. Cold Heading: The cut blanks are fed into a cold heading machine, where the screw head is formed by applying high-pressure force without heating the material. Thread Rolling: Threads are created through a rolling process, where the blank is passed between hardened dies to ensure a strong and accurate thread profile. Heat Treatment: Depending on the material, screws are heat-treated to enhance their strength, durability, and wear resistance. Surface Finishing: A protective coating or plating is applied to prevent rust and improve appearance. Common finishes include zinc plating, galvanizing, or black oxide coating. Quality Inspection: Each screw undergoes rigorous quality checks for dimensions, threading accuracy, tensile strength, and finish. This ensures they meet international standards. Packaging: Machine screws are packed in bulk or customized quantities, labeled with size and specifications for easy identification. Customization Options: We offer tailored designs for machine screws to meet specific requirements, including variations in head shapes (flat, round, hex), drive types (Phillips, slot, hex), and material grades. Our commitment to quality and precision ensures that every screw contributes to the seamless operation of your machinery or assembly line.
LVT (Luxury Vinyl Tile) is another name for PVC sheet flooring. In 2013, Gwell successfully developed LVT floor extrusion lamination production line, and realized one-time lamination of WPC floor laminating materials, which improved production line efficiency and quality stability. It has been exported to some countries in Europe and America. Because its design and color are rich, it is popular to be used at home outfit and commercial domain. LVT extrusion production process: floor materials such as PVC plasticizer, calcium powder, mixed by high speed mixer mixing and delivered by rotating conveyor to the conical twin-screw extruder, then extuded by T die and attach the wear-resisting layer and printing layer to the product with specified thickness. Extrusion laminating process can replace the traditional rolling, laminated and complex process. It is easy to operate, has low investment cost, and can reduce the labor intensity of workers. Also it can keep workshop clean, and the production line will adopt optical sensor detection and alarm, so it has a high degree of automation.

A machine screw is a screw with a slotted head or socket heads often used for fastening metal parts securely together in various types of machinery or construction. Machine screws are unique, though, because of their size. These are used in threaded holes and are likely to end up with a stronger joint.
