Recently, we officially launched the upgraded TR-2D series two-die thread rolling machine, targeting the fast-growing demand for high-efficiency, high-precision thread processing in the global fastener manufacturing industry. Against the background of intelligent transformation in the hardware manufacturing sector, this new model integrates an optimized mechanical structure, automatic control system and durable core components, helping downstream enterprises achieve large-scale mass production with lower unit cost and higher product consistency.
As a classic cold forming solution for external thread processing, the two-roll thread rolling process has long been the mainstream choice for batch fastener production due to its high material utilization rate and improved metal mechanical properties. The TR-2D series further upgrades the core structure on the basis of traditional two-die equipment: the high-rigidity integral cast steel fuselage reduces vibration during high-speed operation by more than 30%, and the precision-machined crankshaft transmission system ensures fully synchronous operation of the two rolling dies with stable and uniform extrusion force. Equipped with high-quality alloy steel rolling dies, the machine completes thread forming in one pass through cold extrusion. The processed threads feature clear tooth profile, smooth surface finish and continuous metal fiber flow, which significantly improves the tensile strength and fatigue resistance of threaded products compared with traditional cutting processing. The thread precision stably meets ISO 4h–6g international standards, and the dimensional consistency deviation of mass-produced parts is controlled within ±0.006mm, fully satisfying the quality requirements of high-end industrial fasteners.
In terms of automated production, the TR-2D series two-die thread rolling machine is equipped with a fully automatic vibratory bowl feeding system as standard, which realizes orderly arrangement and automatic feeding of workpieces without manual intervention. The PLC control system with an intuitive touch screen interface supports one-click parameter setting for different specifications, and the production speed can be adjusted steplessly from 60 to 180 pieces per minute according to product size and material hardness. The whole production workflow from feeding, thread rolling to finished product discharging is fully automated, and can be seamlessly connected with the front-end cold heading production line to build an unmanned fastener production workshop. The built-in automatic circulating cooling and lubrication system provides continuous cooling and lubrication for rolling dies and workpieces during operation, which not only improves thread surface quality, but also extends the service life of rolling dies by more than 25%, supporting 7×24 hours of continuous industrial production.
To adapt to the diversified production demands of customers, this series of equipment optimizes the quick-change structure of rolling dies. The replacement and debugging time for different product specifications is shortened by 40% compared with traditional models, greatly reducing downtime during product switching. The system is also equipped with a die wear monitoring function, which gives early warning of die loss status to avoid batch defective products caused by die wear, controlling the scrap rate of mass production below 0.9%. The equipment has low requirements for operators. After simple training, workers can complete daily operation and routine maintenance. The modular component design makes after-sales maintenance more convenient, and common faults can be quickly located and solved, effectively reducing the operation and maintenance cost of the equipment throughout its life cycle.
The TR-2D series two-die thread rolling machine has wide processing adaptability. It can process various metal materials such as carbon steel, alloy steel, stainless steel, copper and aluminum, and is suitable for producing hex bolts, machine screws, self-tapping screws, studs, threaded rods, anchor bolts and other standard and non-standard threaded parts. At present, this equipment has been widely applied in fastener manufacturing, automotive parts, photovoltaic hardware, construction engineering, furniture hardware and other industries. For manufacturing enterprises, introducing this two-die thread rolling machine can not only effectively increase production capacity and improve product quality, but also reduce labor input and material waste, with a significantly shorter investment payback period than similar high-end equipment.
While providing high-quality equipment, we also offer customers a full range of supporting services. All TR-2D series two-die thread rolling machines come with a 12-month whole-machine warranty and lifetime technical consultation support. We can provide customized services according to customers' product specifications, production capacity requirements and factory layout, including adjusting equipment parameters, matching feeding and discharging mechanisms, and providing automated production line transformation solutions. In addition, we have a professional after-sales service team that can provide on-site installation, commissioning and operator training services to ensure the equipment can be put into production quickly and stably after delivery. Original spare parts are supplied for a long time to solve customers' worries in long-term production.
With the continuous growth of global demand for high-quality fasteners, we will continue to focus on the R&D and innovation of thread forming equipment, launch more cost-effective and reliable industrial equipment, and grow together with customers in the fastener manufacturing industry around the world.
