Product Introduction

Our bolt forging machine is a heavy-duty cold forging equipment specially designed for the production of large-size and high-strength bolts. It adopts advanced closed die forging technology and can produce bolt products with large diameters, long shanks and complex head shapes that cannot be processed by traditional cold heading machines. With 25 years of forging technology accumulation, the Rayliter brand has created this bolt forging machine, which has become the preferred equipment for high-strength bolt production in the global heavy industry field for its strong forging force, excellent forming accuracy and stable operation performance.

Our bolt forging machine adopts an integral cast steel bed and a prestressed frame structure, which can provide a forging force of up to 2000 tons, easily coping with the forging needs of high-strength alloy steel. The equipment is equipped with a high-precision feeding mechanism and a mold positioning system, with a forming accuracy of ±0.05mm, ensuring the interchangeability and assembly accuracy of bolts. At the same time, we have optimized the transmission system and lubrication system, reducing the energy consumption and wear of the equipment, and extending the service life of the equipment. Compared with the traditional hot forging process, the bolts produced by our cold forging process have higher strength, better surface quality, higher material utilization rate, and production costs reduced by more than 30%.

 

Application Fields

Our bolt forging machine is mainly used in heavy industry fields with extremely high requirements for bolt strength and reliability. In the wind power industry, it can produce high-strength large-size bolts for connecting wind power towers, blades and hubs, which need to withstand huge loads and harsh natural environments; in the bridge and steel structure industry, it is the key equipment for producing high-strength bolts for bridge steel structures, high-rise buildings and large venues; in the petrochemical industry, it can produce high-temperature and high-pressure resistant bolts for oil drilling platforms, pipelines and pressure vessels; it is also widely used in shipbuilding, engineering machinery, rail transit and other industries, providing high-quality high-strength bolt products for these fields.

Quality Control

We have established a strict whole-process quality management system to ensure that each bolt forging machine meets our high-quality standards. Starting from raw material procurement, we conduct strict quality inspections on all raw materials and components such as steel, motors and electrical components, and only products that meet the standards can enter the production link. During the production process, our professional quality inspectors conduct patrol inspections and random inspections on each process to ensure the processing accuracy and assembly quality of components.

Each piece of equipment undergoes a strict quality inspection process before leaving the factory, including parts inspection, assembly inspection, 72-hour no-load trial operation and load trial production. We will simulate the actual production environment of customers and conduct forging tests using high-strength alloy steel to comprehensively test various performance indicators of the equipment to ensure stable operation and reliable performance. We also accept inspections by third-party inspection agencies designated by customers, allowing you to purchase with confidence. Our products have passed CE certification and comply with relevant international industry standards, providing customers with reliable quality assurance.

Packaging and Transportation

We attach great importance to the packaging and transportation of equipment to ensure that each bolt forging machine can be delivered to customers safely and intact. Due to the heavy weight and large volume of the equipment, we adopt special packaging and transportation solutions. For domestic transportation, we wrap the whole machine with thickened transparent film, protect all vulnerable parts and protruding components with multiple layers of high-density pearl cotton foam, and fix the equipment base with high-strength I-beams as a whole to prevent displacement and collision during transportation.
For export transportation, we adopt FOB trade terms. In addition to basic packaging, we will customize fumigated wooden case packaging according to customer requirements, with moisture-proof and buffer materials filled inside the wooden case to adapt to long-distance sea transportation. We have established long-term cooperative relationships with multiple professional large-piece transportation logistics companies, which can provide door-to-door transportation services for customers and track the cargo transportation status in real time. Before the equipment is shipped, we will conduct a comprehensive inspection and cleaning of the equipment, and provide a detailed packing list, equipment operation manual and maintenance manual to facilitate customers' receipt and use of the equipment.

Qualification Certification

We always put product quality and safety first, and have established and strictly implemented a perfect quality management system. All bolt forging machines have passed CE certification, comply with relevant EU safety, health and environmental protection standards, and can freely enter the markets of Europe and many other countries and regions around the world. Our production process is strictly controlled in accordance with the ISO9001 International Quality Management System standards, with clear quality standards and inspection procedures for every link from raw material procurement to finished product delivery.
We have a number of independently developed patented technologies and are in a leading position in the industry in the design and manufacturing of heavy-duty bolt forging equipment. With reliable product quality and a perfect service system, our products have been exported to many countries and regions in the Middle East, West Asia, India, Russia, Africa and South America, winning wide recognition and a good reputation from customers at home and abroad. We will continue to commit to technological innovation and product upgrading to provide customers with more high-quality products and services.
