Precision-engineered fastening solutions calibrated to meet strict international tolerances and localized Malaysian industrial guidelines.
Established in 2006, Sinsun Hardware has grown to become Northern China's largest producer of Self-Tapping Screws and a premier global manufacturer of industrial blind rivets. Operating from our state-of-the-art 30,000 sqm integrated production facility, we maintain absolute structural oversight at every stage of the manufacturing process.
Our infrastructure includes a 12,000 sqm smart warehouse holding an excess of 18,000 pallets. Backed by multi-lingual support centers, we ship over 8,500 containers annually to the Middle East, Southeast Asia, South America, and Russia. We bring precision-engineered fastening solutions directly to Malaysia’s key manufacturing and logistics hubs.
Understanding local supply demands under the New Industrial Master Plan (NIMP) 2030
As Malaysia advances its position in global supply chains, key regions like the Klang Valley, Johor Bahru, and Penang demand high-performance mechanical fasteners to support automation and precision manufacturing. Blind rivets (popularly known as pop rivets) play an essential role in various sectors across the country:
For micro-electrical enclosures, server racks, and heat shields. Mechanical fasteners must offer minimal vibration looseness, anti-corrosive finishes, and tight tolerances down to ±0.02mm to ensure board protection.
Automobile structural components require high shear strength (>1,000 MPa) to endure continuous fatigue. OEMs and Tier-1 suppliers in Malaysia count on verified carbon-steel and stainless-steel dome-head peel rivets for bumper and dash assemblies.
With massive solar projects sprouting across Kedah and Johor, framing systems require structural rivets capable of handling high wind loads. Salt-spray resistance reaching over 1,000 hours is vital for these outdoor assemblies.
Why Tier-1 industrial buyers across Malaysia partner with Sinsun Hardware
Our production facilities host over 200 German-imported multi-station cold heading machines and precision Taiwanese tooling. This machinery operates at speed and high capacity, outputting 1,200+ pieces/minute/machine with exceptional repeatability.
We operate 4 continuous gas-fired heat treatment lines with a combined 20-ton daily capacity. Precise atmosphere control manages carbon restoration, ensuring our blind rivet mandrels hit target tensile thresholds (HRC 28-32) to prevent premature pin failure.
Sinsun sources raw wire rods exclusively from premium producers like Xing Tai Steel and Ansteel Group. Prior to heading, we perform in-house spheroidizing annealing to guarantee a uniform microstructure and seamless metal flow.
Every single production batch undergoes 12 strict quality checkpoints. We verify dimension tolerances (±0.02mm), shear/tensile breaking values, surface finish (Ra ≤ 0.4μm), and plating thickness via electromagnetic scanners.

How Sinsun Hardware solves fastening challenges for industrial projects in Malaysia
Challenge: A Tier-1 automotive assembly facility in Shah Alam was experiencing mandrel-pull through and joint failures in bumper brackets, resulting in high scrap rates on their assembly line.
Sinsun Solution: We provided custom multi-grip peel rivets designed with an expanded blind-side footprint and a reinforced mandrel head. This design spreads clamping loads across wider areas, accommodating varied panel thicknesses.
Result: Joint failures dropped to zero, assembly scrap rates decreased by 18%, and the components successfully passed 2,500 hours of continuous vibration testing.
Challenge: A coastal infrastructure contractor required blind rivets for aluminum seawater intake channels that could withstand extreme tropical marine corrosion.
Sinsun Solution: We supplied closed-end marine grade aluminum-magnesium alloy (AlMg5) rivets with passivated stainless steel mandrels, ensuring a tight seal that prevents water ingress.
Result: These assemblies have run for over three years with no signs of galvanic corrosion or sealing failures, meeting the project's longevity requirements.
