In the dynamic and highly specialized field of plastic processing and extrusion machinery, Moiron has emerged as a leading force in China, dedicated to providing top-notch extruder screw barrels and related components. With decades of combined industry experience, our company has continuously evolved to meet the ever-changing demands of customers, both domestically and internationally.

Moiron was founded with a clear vision: to become the go-to source for high-quality screw barrels and comprehensive solutions in the extrusion and injection molding industries. Located in [specific region in China known for its industrial prowess], our state-of-the-art manufacturing facility spans over 1000 square meters and houses the latest machinery and technology. This enables us to maintain strict quality control at every stage of production, from raw material sourcing to the final finishing touches on each screw and barrel.

Our team consists of highly skilled engineers, technicians, and craftsmen who bring their expertise and passion to work every day. They are well-versed in the intricacies of screw and barrel design, manufacturing, and maintenance, ensuring that each product that leaves our factory meets or exceeds industry standards.

Our flagship products, extruder screw barrels, are engineered to perfection. We offer a wide variety of sizes and configurations to suit different extrusion applications, whether it's for plastic pipe production, film extrusion, or profile extrusion. The screws are meticulously designed with optimized flight geometries and helix angles to ensure efficient material conveyance and melting, while the barrels are made from high-quality alloy steels with precise internal diameters and surface finishes to withstand high pressures and temperatures.

The feed section is a critical part of any extrusion process. Our feed barrels and feed screws are designed to provide a consistent and reliable supply of raw materials into the extrusion system. The feed screws have carefully calculated pitches and depths to handle different types of plastics, from granular resins to powders, preventing bridging and ensuring smooth feeding. The feed barrels are equipped with features like cooling jackets or heaters, depending on the requirements, to maintain the ideal temperature for material handling.

For the injection molding industry, we manufacture specialized screws and barrels. Injection molding screws need to rapidly melt and homogenize the plastic material within a short cycle time. Our designs incorporate features such as mixing sections and non-return valves to enhance the melting efficiency and prevent backflow. The barrels are engineered to withstand the high injection pressures and provide uniform heat distribution, resulting in high-quality molded parts with excellent surface finish and dimensional accuracy.

These are custom-designed for specific mold applications. They play a crucial role in ensuring the proper filling and packing of the mold cavities. Mold screws are often tailored to the unique requirements of the molded product, such as the wall thickness, complexity of the part, and the type of plastic being used. Our engineers work closely with customers to develop the optimal mold screw design for their projects.

In certain conveying and dosing applications, timing screws are essential. They are used to accurately meter and transport materials at a controlled rate. Moiron's timing screws are manufactured with precision machining to ensure consistent pitch and diameter along the entire length.

We also produce a range of barrel valves, including pressure relief valves, check valves, and flow control valves. These valves are integrated into the barrel system to regulate pressure, prevent overpressure situations, and control the flow of molten plastic. They are made from durable materials and engineered to provide reliable performance in harsh operating conditions.

Our screw manufacturing process begins with the selection of high-grade alloy steels. These materials are carefully inspected for chemical composition and mechanical properties to ensure they meet our strict standards. The raw material is then machined using advanced CNC lathes and milling machines. The screw flights are cut with extreme precision, and the surface is finished to a smoothness that minimizes friction and wear. Heat treatment is a crucial step, where the screws are hardened and tempered to achieve the desired hardness and toughness, enhancing their durability and performance in high-stress extrusion environments.

Barrel manufacturing at Moiron is equally meticulous. We use seamless alloy steel tubes as the base material. The internal diameter of the barrel is precision-ground to exacting tolerances to ensure a perfect fit with the screw. The outer surface is often machined to accommodate cooling channels or heating elements, depending on the application. The barrels are then subjected to a series of surface treatments, such as nitriding or chrome plating, to improve wear resistance and corrosion resistance, prolonging their service life.

At Moiron, quality is not an afterthought; it's embedded in every step of our operation. We have implemented a comprehensive quality management system that adheres to international standards.

Before any screw or barrel leaves our factory, it undergoes a rigorous inspection process. This includes dimensional checks using precision measuring instruments to ensure that the screw diameter, barrel internal diameter, and other critical dimensions are within tolerance. We also perform hardness testing, metallurgical analysis, and surface finish inspection. For extruder screw barrels and injection molding screws, we conduct performance testing under simulated operating conditions to verify their functionality and efficiency.

Accurate measurement of screw diameter is crucial for proper fit and performance. We use calibrated micrometers, laser measurement devices, and coordinate measuring machines (CMM) to measure screw diameters at multiple points along the length. This ensures that any taper or out-of-roundness is detected and corrected. For other dimensions like screw pitch, flight depth, and barrel length, we have established standardized measurement procedures to maintain consistency and accuracy.

Over time, the internal lining of barrels can wear out due to the abrasive nature of molten plastics. Moiron offers professional barrel relining services. We remove the worn-out lining and apply a new, high-performance coating. This not only restores the barrel's original dimensions but also improves its wear resistance, allowing customers to extend the life of their existing barrels and reduce replacement costs.

In case of damage or wear, our team of experts can perform comprehensive screw and barrel repair. We can refurbish damaged screw flights, replace worn-out barrel sections, and realign components to bring them back to optimal working condition. Our repair services are prompt and cost-effective, minimizing downtime for our customers.

Understanding that each customer has unique requirements, we offer customization services. Our engineers work with clients to design and manufacture screw barrels tailored to their specific extrusion or injection molding processes. Additionally, we provide technical support throughout the product's lifecycle. Whether it's installation guidance, troubleshooting, or process optimization advice, our team is just a phone call away.

Our products find applications in a wide range of industries.

In the production of plastic pipes, profiles, sheets, and films, our extruder screw barrels are the backbone of the production lines. They enable manufacturers to produce high-quality products with consistent dimensions and properties, meeting the demands of construction, packaging, and automotive industries, among others.

For the manufacturing of plastic parts used in electronics, consumer goods, and medical devices, our injection molding screws and barrels play a vital role. They ensure the precise filling and molding of complex part geometries, with excellent repeatability and minimal defect rates.

From plastic bags to rigid containers, our screw barrels are involved in the extrusion and molding processes that create packaging materials. The ability to handle different types of plastics and achieve high production speeds is essential for meeting the fast-paced demands of the packaging sector.
