Empowering high-end manufacturing with precision metal parts and leading the wave of industrial innovation

Today, with the deep integration of Industry 4.0 and intelligent manufacturing, the performance and precision of metal parts have become the core indicators for measuring the level of high-end manufacturing. As a pioneer in industry technology, Hangzhou Public Hardware Co., Ltd. deeply empowers strategic fields such as automobiles, aviation, electronics, and medical care with core products such as machined parts, spring series products, and customized fasteners, and reshapes the manufacturing standards of metal parts with "millimeter-level precision" and "innovative design".

Intelligent manufacturing drives industrial upgrading

As a benchmark enterprise in the field of mechanical processing, Public Hardware realizes full-process automation and flexible production through the Industrial 4.0 production line, covering high-end needs such as key components of automobile engines, precision components of medical equipment, and high-strength structural parts of aerospace. Its machined parts are known for their "zero defect" quality. They adopt modular design and green manufacturing processes to significantly reduce energy consumption and material waste while improving production efficiency. For example, the motor shaft parts provided for new energy vehicles achieve a mirror effect with a surface roughness of Ra0.4 through five-axis linkage processing technology, greatly extending the product life.

Technological breakthrough from torsion to traction

In the field of springs, Public Hardware has built a complete product matrix covering torsion springs, double torsion springs and traction rod springs:

Torsion springs: using high-strength spring steel materials, optimizing stress distribution through heat treatment process, achieving fatigue life of millions of times in scenarios such as automobile clutches and industrial robot joints, and technical indicators reaching international advanced levels.

Double torsion springs: original bidirectional symmetrical structural design, while providing double torsion torque in medical equipment, smart home appliances and other fields, through zinc plating + nickel plating composite coating to achieve 96 hours of salt spray test without corrosion, breaking through the durability limit of traditional springs.

Spring traction rod: integrating lightweight design and high-precision assembly technology, providing core support for rail transit shock absorption systems and engineering machinery hydraulic devices, successfully replacing imported products, and helping the process of domestic equipment independence.

Build a solid manufacturing foundation with "industrial rice"

Facing the stringent requirements of high-end equipment on fastener performance, Public Hardware has created a full-chain solution from material research and development to intelligent manufacturing:

High-strength customized parts: using aerospace-grade alloy steel, through cold heading + heat treatment integrated process, to achieve a tensile strength of over 1200MPa, widely used in heavy projects such as wind turbine towers and bridge steel structures.

Intelligent fastening system: Develop embedded sensor fasteners to monitor torque and looseness in real time, and provide predictive maintenance solutions for industrial robots, data center servers and other equipment.

Lightweight innovation: Using topological optimization technology, while ensuring locking performance, the weight of automobile chassis fasteners is reduced by 30%, helping new energy vehicle companies achieve a breakthrough in endurance.

Technology empowerment: creating a metal parts industry ecosystem

Public Hardware's technological innovation is not limited to the product level, but also extends to the field of industrial chain collaboration:

Build a virtual simulation system from design to production, shorten the new product development cycle by 50%, and increase the first trial production pass rate to 98%.

Materials Laboratory: Joint R&D center established with universities, successfully developed special materials such as -60℃ spring steel and non-magnetic stainless steel fasteners, filling many domestic gaps.

Global service network: Technical service centers are set up in Southeast Asia and Europe to provide value-added services such as localized selection design and failure analysis, and realize the global output of the "China Solution".

Casting the industrial foundation with the spirit of precision

From the intelligent production line in the machining workshop to the microscopic inspection of the spring laboratory, from the personalized production of customized fasteners to the localized service of the global market, Hangzhou Gonggong Hardware Co., Ltd. is redefining the value connotation of metal parts manufacturing with "technical depth" and "service temperature". Driven by the dual goals of "dual carbon" and "dual circulation" strategy, this company based on precision is working with global partners to open a new chapter in high-end manufacturing.
