Explore our foundational range of precision machines, die & punch sets, industrial fasteners, and structural anchors engineered to strict DIN, ANSI, and ISO standards.
In modern high-speed metal forming and cold forging industries, Machines Die & Punch sets are the vital core components that determine the precision, speed, and cost-effectiveness of parts production. Precision punches, header dies, thread rolling dies, and custom forming tools are subjected to extreme cyclical stress, thermal shock, and mechanical wear. As a leading manufacturer and exporter, Sinsun Hardware addresses these challenges by supplying tools made from premium alloys, including tungsten carbide and high-speed tool steels.
Our global commercial clients spanning the automotive, aerospace, construction, and electronics sectors require cold heading tooling that delivers exceptional wear resistance, high impact toughness, and prolonged service life. By integrating advanced raw material processing with high-precision manufacturing, we ensure that every punch and die facilitates maximum uptime on multi-station headers, keeping manufacturing lines running seamlessly worldwide.
How we achieve tolerances of ±0.02mm and surface roughness of Ra ≤ 0.4μm using German engineering and Taiwanese technology.
We source our raw materials exclusively from premier mills such as Xingtai Steel and Ansteel Group, utilizing high-grade carbon steels, high-tensile alloy steels, and tungsten carbide. The microstructural integrity of our materials is ensured through in-house spheroidizing annealing, resulting in tooling that resists chipping and cracking under extreme stress.
Our tooling workshop and cold heading lines feature German-imported multi-station cold heading machines and precision Taiwanese processing lines. We employ tail-gripping mechanisms for drill screw tooling, custom EDM thread profiling, and automated CNC grinding to achieve dimensional tolerances as tight as ±0.02mm.
Every punch and die undergoes dedicated thermal processing across our four in-house heat treatment lines, securing a consistent hardness profile of HRC 28-32 for target fasteners and up to HRC 62 for forming tools. We apply PVD and CVD coatings (such as TiN, TiCN, and AlTiN) to minimize friction and extend tool life by over 300%.
A timeline of Sinsun's continuous manufacturing expansion, technological integrations, and worldwide logistics breakthroughs.
Sinsun Hardware was founded with a vision to deliver reliable fastening and tooling solutions, establishing our primary manufacturing plant in Northern China.

Introduced German multi-station cold heading machinery and precision Taiwanese quality testing devices, minimizing tool error to micrometer levels.
Commissioned a 12,000 sqm smart warehouse holding over 18,000 pallets. Implemented a fully integrated ERP system to track and expedite global shipments.
Achieved an annual output of 36,000 tons with four advanced in-house heat treatment lines and custom gas-fired spheroidizing annealing furnaces operating 24/7.
How Sinsun collaborates with global engineering and procurement teams to turn raw ideas into verified, high-performance tooling.
Our engineers partner with your technical division to analyze cold forming challenges, machinery constraints, and material requirements.
We generate 3D models and CAD blueprints of the custom punch or die. Rapid prototyping is conducted to verify form, fit, and feed paths.
Tooling samples are subjected to rigorous testing, including finite element analysis (FEA), impact resistance testing, and metallurgical evaluation.
Mass production starts on high-speed machining centers, followed by precise heat treatment to achieve optimal hardness and structural toughness.
Our dedicated laboratory inspects every batch for dimensional accuracy, concentricity, and surface finish before dispatch.
Custom protective packaging prevents corrosion during transit, backed by complete customs documentation and global shipping coordination.
Discover how Sinsun Hardware partners with automotive and offshore companies to resolve structural engineering and tooling challenges.
Challenge: A Tier-1 automotive manufacturer was facing frequent punch cracking and tooling wear during the manufacture of M10 high-strength engine flange bolts (Class 10.9), leading to regular downtime.
Sinsun Solution: We developed custom carbide-tipped punch pins and cold heading insert dies using an optimized WC-Co alloy composition, combined with an AlTiN PVD coating to reduce friction and wear.
Result: Tooling lifespan increased by 220%, machinery uptime was restored to 98.5%, and the manufacturing cost per unit dropped significantly.
Challenge: A marine engineering client required robust tooling capable of cold forming high-hardness duplex stainless steel anchors without material galling or structural cracking.
Sinsun Solution: We designed heavy-duty forming dies using premium tool steel (M2 grade), processed through vacuum heat treatment and gas quenching, followed by a double-tempering cycle to maximize toughness.
Result: Zero die failures reported during production, maintaining clean anchor threads and dimensional tolerance compliance across a run of 500,000 units.
