2005: Starting in Pingshan, Shenzhen

In 2005, YF Zhichengjia was officially established in Pingshan, Shenzhen. At that time, China's precision fastener industry was transitioning from rough machining to precision manufacturing. The domestic market was dominated by low-cost, general-purpose fasteners, and the high-end precision segment was largely imported. The company chose to start with precision small screws, taking "accurate manufacturing, fast delivery" as its foundation. This was a deliberate niche choice: rather than competing on price in the commodity bolt market, the company focused on the tiny, high-precision screws that consumer electronics and telecommunications equipment needed, where tolerance requirements and consistency mattered far more than raw tonnage. Today's headquarters is still located in Kengzi, Pingshan, Shenzhen, around Zhongxing Road, serving as the hub for the company's R&D, management, and precision small-parts manufacturing.

2008-2013: From Phone Precision Screws to Automotive Supply Chain

2008 was the company's first step: it entered a leading customer's phone business and subsequently fully integrated into the industry's top-tier phone supply chain. Consumer electronics demand extremely high precision and consistency from miniature screws. Phone internal space is compact to the millimeter, and screws as small as M0.5 must hold together displays, batteries, and camera modules without failing over years of daily handling. A head offset of 0.05mm on a micro screw can disrupt automated assembly. This experience built the company's manufacturing capability for M0.5~M2 ultra-precision fasteners and established the optical sorting and automated inspection routines that now serve all product lines.

In 2013, the company obtained IATF 16949 automotive quality management system certification and formally entered the automotive industry supply chain. Moving from consumer electronics to automotive meant quality standards, traceability, and PPM-level defect control all had to step up a grade. Automotive customers demand PPAP documentation, FMEA, SPC, and full lot traceability from furnace heat number to delivery batch - a step-change from consumer electronics. This certification laid the groundwork for the later entry into new energy, because the NEV supply chain inherits the same automotive-grade quality expectations.

2017: Cold-Heading Transition into New Energy Vehicles

2017 was the turning point in the company's manufacturing philosophy. Through process optimization, the company switched aluminum sleeve production from CNC machining to cold heading, entering the NEV supply chain in one move. Cold near-net forming not only retains the complete metal flow line and improves strength but also dramatically reduces cost - internal data shows that switching CNC to cold heading can bring about a 20% cost reduction. The economic logic is straightforward: CNC turns a solid bar into chips, with material utilization around 50%; cold heading reshapes the wire in a die in seconds, with material utilization near 98%. This transition upgraded the company from "making precision small parts" to "making structural components and system-level joining solutions," and it was the process foundation that later enabled the 600MPa-class aluminum bolt development.

2023: Xiangyang Subsidiary and Wire Thread Insert Business

In 2023, the company established a subsidiary in Hubei - Zhichengjia Metal Technology (Xiangyang) Co., Ltd. - fully entering the NEV supply chain and simultaneously developing the wire thread insert (thread insert) product line. The Xiangyang base is close to the central China NEV vehicle and three-electric industrial belt, which includes major OEM assembly plants and their Tier-1 suppliers. Locating manufacturing there means shorter delivery radius to automotive customers and lower logistics cost. The base undertakes scaled manufacturing of automotive-specialty parts and wire thread inserts, forming a dual-base structure with the Shenzhen headquarters that handles precision small parts and R&D.

2025: Indonesia Setup and Today

In 2025, the company established an Indonesian subsidiary to further expand international business, forming a global production footprint of Shenzhen headquarters, Xiangyang base, India, and Indonesia. To date, the company has grown into an innovative enterprise with industry leadership in precision fasteners and aluminum components: ~500 million pieces per month, 26 active patents, serving 100+ customers, with products covering mid-to-high-end markets such as new energy vehicles, embodied intelligence, HPC AI servers, low-altitude economy, and consumer electronics. The customer mix has shifted dramatically over twenty years: from the early days of consumer electronics screws, to automotive fasteners after 2013, to NEV structural parts after 2017, and now to humanoid robot joints and AI server rack fasteners. Each shift required a new capability - tighter tolerances, higher strength, new materials, or a new certification - and the company invested ahead of the curve rather than after losing a bid. This pattern of building capability before the market arrives is the common thread running through all five milestones.
