As a professional enterprise focusing on R&D, manufacturing and technical services of high-precision progressive stamping dies, we are proud to launch our flagship Curling Die – a revolutionary progressive stamping curling die specially designed for circular parts processing, which breaks the long-standing technical barriers in the stamping industry. For a long time, the production of thick circular curling parts has been limited to single die processing due to the lack of strip connection area during curling forming, resulting in extremely low production efficiency and difficulty in realizing automatic mass production; most manufacturers in the industry cannot solve this technical difficulty and fail to develop progressive curling dies.
Our R&D team has broken through industry technical bottlenecks through years of research and innovation, independently designing a unique progressive curling die with a "part pushing part" feeding structure, successfully realizing automatic continuous stamping and curling forming of circular parts. This innovative die solves the core pain points of low efficiency of single die processing and difficulty in automatic production of circular curling parts, delivering high precision, high efficiency and long service life, making it the ultimate solution for high-quality mass production of circular stamping parts.
Circular Parts Precision Curling Forming: The core function of this curling die is to complete high-precision curling processing of various circular stamping parts, especially for thick circular parts that are difficult to process with traditional dies, ensuring uniform and standard curling forming effect.
Progressive Die Automatic Feeding Production: Adopts the innovative "part pushing part" feeding structure, abandoning the traditional strip feeding method, realizing automatic feeding and continuous processing of circular parts without connecting strips, and completing full-automatic production from forming to final blanking.
Micron-Level Dimensional Control: Precisely controls the inner circle size tolerance of circular parts, which is the critical assembly size of finished parts, and fully meets the strict assembly matching requirements of downstream products.
Wide Thickness Range Adaptation: Supports stamping and curling processing of parts with a thickness range of 0.05mm to 3.00mm, covering ultra-thin precision parts to thick conventional parts, with strong adaptability.
High-Precision Punching & Forming Integration: Integrates precision punching, curling forming and final blanking in one progressive die process, reducing multiple processes and manual operation, improving production efficiency and product consistency.
Stable Long-Term Mass Production: Designed for industrial mass production, with stable structure and reliable performance, ensuring consistent product quality and dimensional accuracy during long-term continuous operation.
Our progressive curling die stands out in the global stamping die market with exclusive innovative technology and outstanding performance advantages, completely surpassing traditional single curling dies and solving the industry's long-term production pain points, bringing a comprehensive efficiency upgrade for circular parts processing.
Industry-Breaking Feeding Structure: The exclusive "part pushing part" automatic feeding structure is the core technical breakthrough, which allows formed parts to push the subsequent parts into the next forming station for continuous processing, and finally completes blanking, perfectly solving the problem that circular curling parts without connecting strips cannot be produced by progressive dies.
Ultra-High Processing Precision: The die processing tolerance can reach an ultra-fine +/-0.007mm, with strict control of the inner circle critical assembly size; the inner core is designed to imitate the product matching parts, and two-station forming is adopted to ensure that the finished parts fully meet the tolerance requirements.
Ultra-Long Service Life: The designed working life of the curling die is up to 1 million strokes, thanks to the selection of high-quality mold materials and precision manufacturing process, supporting long-term stable mass production and reducing die replacement and maintenance costs.
Wide Processing Range: Adapt to part thickness from 0.05mm to 3.00mm, and the minimum punching hole diameter can reach 0.08mm, covering various precision and conventional circular curling parts, meeting diverse processing needs of different industries.
High-Efficiency Automatic Production: Replaces traditional single die manual processing with progressive die automatic production, greatly improving production efficiency, reducing labor costs and product defective rate, and realizing large-scale standardized production.
Professional Mold Design Team: Our mold workshop has a professional design and manufacturing team with more than 10 years of industry experience, mastering core stamping technology and able to solve various complex stamping and curling processing difficulties.
High-Quality Standard Parts Configuration: Adopts internationally renowned brand standard parts, equipped with MISUMI precision guide pins and bushings to ensure die operation accuracy, and equipped with Kaller high-performance gas springs to ensure stable stamping and feeding.
Our progressive curling die is manufactured in strict accordance with international industrial mold standards, with meticulous material selection and precision processing to ensure durability and stability. The die adopts a standard progressive die structure, with upper and lower die sets made of 45# high-quality steel, with strong structural rigidity and bearing capacity; upper and lower backup plates and punch holder plates are made of D2 steel, heat treated to HRC58-60, with excellent wear resistance and impact resistance.
Core mold working parts are carefully configured: stripper plates and lower die plates adopt high-quality DC53 steel, heat treated to HRC58-60, with good toughness and wear resistance; punches, stripper inserts and die sections also use DC53 steel, with higher standard heat treatment to HRC60-62, further enhancing wear resistance and service life. All mold plates and core working parts have no additional post-treatment after heat treatment, retaining the optimal mechanical properties after precision processing; the entire die is assembled with precision, and the standard parts are strictly selected to ensure long-term stable operation and 1 million strokes of service life.
This high-precision progressive curling die is widely used in various industrial fields that require circular parts curling forming processing, especially suitable for mass production of precision circular stamping parts. Core application industries include hardware manufacturing, for various circular hardware accessories, fasteners and decorative parts; electronic and electrical industry, for precision circular electrical contacts, connector parts and shell components; automotive parts manufacturing, for automotive circular stamping parts and small assembly components; home appliance manufacturing, for various circular accessories and functional parts of home appliances; as well as precision mechanical parts, communication equipment parts and other fields that require high-precision circular curling forming and mass automatic production.
